There are multiple dimensions of diversification beyond 'what' (asset classes): 'how' (style/factor choices) and 'when' (rebalancing decisions); a portfolio with correct asset allocation but all allocated to deep value underperforms if growth outperforms; timing of rebalancing has huge impact.

“There's really just more than one dimension of diversification. We often think about what I call the what dimension as in what are we investing in. [...] But I think we should also think about how those investment decisions are being made and when they're being made, right? [...] if you got your asset allocation correct, uh but you put all your equities into deep value stocks over the last decade, you know, you've sort of lagged behind equity markets. So your how decision wasn't necessarily well diversified.”

Chasing performance—buying what has recently done well—is endemic to human nature (something good brought joy, I want more of it) but is a horrible way to invest; virtually all manifestations of bad investing are forms of performance chasing, including within quantitative communities.

“it's endemic. It's innate in in the human uh uh psyche. The notion of um something's hurt me, get me out of here, something's been good for me, given me profit, given me great joy. I want more of that. This is all very much human nature. It's a horrible way to invest.”

Building wealth is not difficult; it is actually very easy, but people fail to do it because they are constantly lured by 'siren songs' of something new, better, and sexier that causes them to crash on the rocks—analogous to Ulysses being tempted by sirens.

“building wealth is not difficult. It's actually very easy. So why don't people do it? And the answer is that there's always a siren song of something new, better, sexier, something. And to continue on the Greek mythology there, and then people go and they crash on the rocks, right?”

Liquidity is everything in trading and investing—both in terms of market liquidity (ability to buy/sell at fair prices) and personal liquidity (ability to hold positions without forced liquidation). Positioning yourself in illiquid positions during periods of illiquidity is guaranteed to cause losses.

“Liquidity. That word is everything. Liquidity can mean the thing that spurs demand and that creates enough liquidity to keep it going. It can also mean the removal of it, right? Is there isn't enough demand or there's not enough money to go around. But it's also important to think about when you're trading or your positioning, how liquid you are and how liquid the things you're investing. And ultimately, it doesn't matter how much demand there is today or tomorrow for something that won't ultimately have liquidity at some point. Doesn't matter what its earnings are if it doesn't have access to markets.”

Be flexible as an investor, not dogmatic—don't commit to a single strategy (value-only, growth-only, quality-only) but adapt based on what the environment calls for, similar to how football coaches run their offense based on what the defense gives them.

“I think a lot of people get caught up in sticking to like, hey, I've got my one philosophy. I I'm a I'm a low PE investor or I'm a I like to invest in fast growth companies or I like to find the highest quality and that's what I want to invest in. Um I would say what you want to be is you want to be flexible as an investor and um you know I I live in Los Angeles now but I I grew up in the Boston area and I'm a Boston sports fan. I'm a fan of the New England Patriots and our longtime coach Bill Bich. He had a way if if I was going to use a sports analogy, there were a lot of football coaches that their focus is um you know their their belief is I want to have a power run game or I want to have a passing game and that's the the offensive philosophy I believe in. His approach was I want to be flexible enough to run my offense based upon what the defense gives me.”

Fundamental investors should write down their investment thesis at the time of purchase and periodically review outcomes against decisions, because it's easy to forget why you did something and conflate luck with skill when a stock rises for the wrong reason.

“I think you need to write down what you're doing at the time that you do it because it takes, if you're a fundamental investor, it takes years really to work out whether the decision that you made actually resulted in the outcome that you thought. And the only way that you learn is by looking at outcomes against decisions. And it's so easy to forget why you did something. And really the worst case scenario as funnly as funny as this sounds but the worst case scenario is when you get some the stock goes up but for a reason that you didn't identify. So you got lucky but then you you start conflating that luck with some skill.”

Investors should view their stock holdings as businesses they own, not as trading vehicles or pieces of paper, because this mental frame prevents costly emotional trading and encourages long-term wealth building through patient ownership.

“Well, it would be that you own a business. You own a business and and this idea that you own a trading sardine uh instead of a business leads to so much bad behavior. And and really you guys raised it the best. Uh you know when Jack was talking about selling those winners, you know, it if you just think that that I own this wonderful portfolio of businesses and I want to pass them on to my kids or my grandkids, I think it it keeps you out of owning stuff because you think it has a quick double and it keeps you out of uh uh selling stuff simply because it doubled.”

When investing, understand why you should get paid for owning an asset and why the counterparty would want to give you that return; if the answer is unclear, you're speculating not investing.

“whenever you're investing in something, make sure you understand why you should get paid for owning this asset, for performing this activity. understand why it not only makes sense for you as the investor but whoever is going to be funding that investment on the other side. Um why it makes sense for them to be giving you the return you need. I would say there's, you know, that there's a lot of errors people can make as investors, but one of the crucial ones that people make time and time again is forgetting about the fact um that if you're going to sustainably get a return, it needs to make sense to give you that return in terms of the person on the other side.”

What matters for investing success is not what you know about the future (which is unknowable) but what you do along the way—i.e., the process and discipline you apply, not the accuracy of your predictions.

“we think it's what we know that matters. Meaning, what's going to happen? What's going to happen in the future? What's the market going to do? Whether we're trying to do that on our own or trying to figure out which Yahoo on TV or which strategist is going to have the best market call. It's not what we know that matters, meaning about the future. It's what we do along the way that matters.”

Base rates—the empirical frequency of outcomes in reference classes—should be a foundational analytical tool for investors, as it provides a more grounded reality check than individual information gathering and personal experience.

“I think that I would encourage people to learn about and apply base rates as they think about the world of investing. By the way, it's not just valuable for investing, but really business or your life actually. It's good for your life. And again, a base rate uh you know the the the basic setup is the natural way to think about the world or solve your problems is to gather a bunch of information and combine it with your own inputs and experience and project into the future. And that's that's what we all do left to our own devices. Using base rate says I'm going to think about what I'm facing now or my problem as an instance of a larger reference class.”

During periods of market volatility and losses (as in growth stocks, crypto, or bond losses), the most important lesson is self-forgiveness combined with willingness to continue taking action, because shame-driven inaction is more destructive than the original mistake.

“I think that something that is really really important especially in this environment, I think that we have a lot of investors who may have felt like they were overexposed to, you know, growth stocks with no earnings. Uh, they may have invested far too much in crypto. Um, you know, I think a lot of investors right now, maybe they invested long on the yield curve and they're kind of shocked to see interest rates rise and they're looking at losses on their bond bond portfolio. And uh, I think that uh, point number one is be kind to yourself. You're only human. It's okay to be human. Don't think of yourself as a god.”

Investors should evaluate each position as if they just purchased it today—asking whether they would buy it at the current price with their current risk preferences—rather than holding out of complacency from past gains or losses.

“Paul basically believes that you should look at your portfolio like you just put everything on that day. You know, you know, it's don't get too complacent. Oh, I've got this position. I I'm well ahead. I don't have to worry about, you know, it's that type of thing. question is if you just put this position on it today, would you be comfortable with it or would you be comfortable with with it where your risk point is”

For most investors, it is better to be like Rip Van Winkle (sleeping through market cycles) than Nostradamus (predicting the future), because public market returns come from time-in-market and diversification, not from avoiding downturns through forecasting.

“despite all the amount of time we spend talking about the future and forecasting and things people should think about. I think um the quote is um for most investors it's better to be uh whip rip van winkle than Nostradamus meaning you know what does everyone on CNBC do all day they like predicting what's going to happen with Google earnings or the price of wheat or what's the Fed's going to do and is gold a good part of their portfolio like all these things everyone stresses about but in reality like coming up with a portfolio particularly with public markets like I want that sucker to be on autopilot I ever want to think about my public market investments ever.”

Individual investors should keep the bulk of their wealth in a simple, straight-and-narrow diversified portfolio and allocate only a small speculative 'play money' portion to riskier strategies, as this separation prevents catastrophic errors.

“my my advice to individual investors has always been to keep to the straight and narrow. Right? If you want to have a little a little puddle of money over here that's your more speculative play money. That's fine. I get that. I mean we all do that. That's fine. I have mine. Not going to share with you the stuff that I blow up in like everybody else. But that's fine, right? But the bulk of your wealth building should stick to the straight and narrow.”

Investors faced with many strategy choices should prioritize finding a good strategy they can stick with over finding the theoretically best strategy they will abandon, because consistency beats optimization.

“I think for most people the good strategy you can stick with is vastly superior to the great strategy that you can't stick with. It's just really hard for people to find that one strategy and stick with it. So I think that's that's kind of the the lesson I impart on a lot of people is just if you find a strategy that works for you, don't worry what everyone else is doing and just stick with your own strategy and and call it a day.”

Diversify broadly and be humble about what you can know, recognizing that the future will likely look quite different from the past in terms of inflation, growth, geopolitical risks, and technological shocks.

“I mean it would be diversify, right? It would be be humble about what you know and what you can know and um don't be over reliant on what you observed in the past. The past is one one sample draw from an infinite variety of potential sample draws that we might we might get in the future in terms of combinations of um inflation, growth, geopolitical risk, supply demand dynamics, technological shocks, etc. And the future is probably going to look quite a bit different from the past. And so the the best way to prepare for the unknown is to diversify.”

When uncertain about a position, cut it in half gradually (scale out) rather than holding or selling everything; this allows you to reduce uncertainty without making a binary all-or-nothing decision.

“you know about how do you get out and I said what do you do when there's a position you have all you just undecided you're not sure if it's just a short-term move against you or you're wrong and he says if he's ever in a situation where he's not sure first thing he does is cut in half and if he's still unsure children a while later cuts it again. He says, "You know what? Before too long, you don't have a problem."”

Stop thinking of savings as investments for getting rich; savings are emergency reserves that need to be available when most needed and to outpace inflation, and this is fundamentally different from trying to get rich off returns.

“stop thinking about your savings as investments. That's where I think the industry's lied to all of us is everybody thinks I'm going to put this money away and I'm going to get rich off of it so then I can retire to a beach somewhere. These are your savings. You need there to be when they need them most and to outpace inflation. As soon as you started thinking about a way to get risk, you're going to take imprudent risks and you're likely going to lose most of them or they can be underwater for decades. So the only way to get rich is in your business, your job, whatever you want to do, but your savings need to be as robust as possible so they'll be there when you need them most.”

The less you think about selling, the more you're thinking about the quality of what you're buying, which is where outperformance actually comes from—not from superior exit timing but from superior entry selection.

“The less you think about selling, the more you're thinking about the quality of what you're buying. So the less you think about selling, the more you're thinking about the quality of what you're buying. It's that simple.”

Do your own independent research to form conviction before investing; even when using others' work, verify it yourself, and large investment wins come not from big wins but from avoiding large losses through independent diligence.

“the most important thing would be just to do your own work. you know, doesn't mean that you can't use other people's work, but I think you need to verify that other person's work. And kind of what we talked about before. I mean the key to this to stock picking is doing independent research to form that independent conviction so you can just know what to do before other people you know and even when I was a private full-time investor yeah I had big big wins but just that independent research and conviction and just having a pulse in that business you know it was the large losses I never took that kept me in the game as much as the big wins”

Try not to sell; instead focus on buying excellent companies as early as possible and letting them persist. If you only had 20 punches (buys) in your lifetime with no sells allowed, you'd invest much more carefully.

“I would say try never to sell um you know we had a lot of fun with sell discipline earlier I think too much is made of it. Um I think I think you have to think about selling a lot if you're not buying good stuff in the first place. Like maybe you were buying it for a trade. You thought maybe we're in a cycle and you'll sell at the end of the cycle. You're trying to time the market. And so so many reasons that people sell are because the thing they bought in the first place, they didn't buy something excellent or they didn't buy something that would persist.”

Being skeptical of consensus when everyone is pessimistic; when consensus says things are terrible, consider what might actually go right; look around at the ground truth rather than accepting the narrative.

“being somewhat skeptical about the consensus uh when when when everybody is so convinced that things are going to go wrong uh ask yourself you know try to think about what what might might go right and again look look around you you know you know uh what do you see do you see doom and gloom or do you see some some optimistic things going on out there?”

Long-term thinking requires believing that companies are trying to build value over time and policy makers are trying to grow the economy; this underlying optimism is necessary to maintain conviction and take a long-term plan seriously.

“they don't trust that people who are running companies are trying to build value over time. Policy makers in general, you know, big maybe quotation marks or something are trying to find ways for the e economy to grow over time or for there to be more wealth accumulation. So long-term, you know, try to be very optimistic and and and and have a long-term plan that you can execute.”

The most important thing in stock picking is doing your own work: verify others' work, form independent conviction, maintain a deep understanding of the business; the largest losses you avoid matter more than the big wins you capture.

“the most important thing would be just to do your own work. you know, doesn't mean that you can't use other people's work, but I think you need to verify that other person's work. And kind of what we talked about before. I mean the key to this to stock picking is doing independent research to form that independent conviction so you can just know what to do before other people you know and even when I was a private full-time investor yeah I had big big wins but just that independent research and conviction and just having a pulse in that business you know it was the large losses I never took that kept me in the game as much as the big wins”

Be flexible and enjoy life; the 4% rule debate misses the point that flexibility (ability to vary spending with life circumstances) is more important than precise sustainability calculations.

“I'd say to to be flexible and also to enjoy life for sure. So I do and kind of this whole 4% rule debate. I do tend to get associated with 4% is high and therefore you've got to be more conservative about your approach to retirement, but being flexible, being able to go with the flow.”

Base rates—the natural frequency of outcomes in a reference class—should be the primary tool for thinking about investing and decision-making, as they correct for the human tendency to overweight personal information and experience.

“I would encourage people to learn about and apply base rates as they think about the world of investing. [...] Using base rate says I'm going to think about what I'm facing now or my problem as an instance of a larger reference class. I'm going to basically ask what happened when other people or organizations were in this position before.”

If you are buying one-week call options on AMC, you are not investing; the counterparty (market maker) is the casino with no reason to give you good returns; you provide only upside exposure (no downside participation), so the counterparty rationally only gets the downside—not a sustainable strategy.

“for the retail investors who are buying, you know, one week call options on AMC, the reality is you're not investing. The person on the other side has no reason to want to give you a high return, right? The person on the other side, for one thing, is a market maker, and the market maker is the casino. The casino is only there to try to make money off of your activity. But the simple truth is, whenever you're buying a call option, you're not doing anything useful. You only get the upside. And if you only get the upside, the person on the other side only gets the downside. There's no reason for them to want to give you a good return in the long run.”

Sustainable investment strategies must make sense for both the investor and the counterparty/funding source; if it doesn't make sense for the other side, it's not a sustainable strategy.

“Whenever you're investing in something, make sure you understand why you should get paid for owning this asset...whenever you're buying a call option, you're not doing anything useful. You only get the upside. And if you only get the upside, the person on the other side only gets the downside. There's no reason for them to want to give you a good return in the long run. So I think investors could avoid a lot of errors if they thought not just about does this make sense for me but does this make sense for me and the guy on the other side if it doesn't make sense for the guy on the other side this is not going to be a sustainable strategy.”

Never sell too much; selling too much creates tax drag and opportunity cost; buy excellent companies as early as possible and let them persist; if you need to sell, you probably didn't buy excellent quality to begin with.

“I would say try never to sell um you know we had a lot of fun with sell discipline earlier I think too much is made of it. Um I think I think you have to think about selling a lot if you're not buying good stuff in the first place. [...] those are the two things that I'm always trying to do is I'm trying to buy things that are excellent as early as possible and I'm going to let that persist for better and for worse. And so I really don't have to think about selling too much.”

Get mastery over data analysis to bust myths; treat everything with skepticism ('if anything seems obvious, probably not true'); compelling stories about investments often have hidden skeletons that undermine simple narratives.

“Get enough mastery over data analysis to be able to do some myth busting and treat everything that you see out there with uh a pinch of salt. and and really try to validate things and also like if anything ever seems obvious in investing probably not true like if anything like so such a clear-cut distinction that it's like obviously I should be all in definitely not the case um and in fact like that feeling should be worries so a deep deep skepticism is probably the biggest lesson I can I can impart”

What matters in investing is not knowledge of the future but what investors do along the way; the focus should shift from trying to predict unknowable future events to executing a disciplined process.

“It's not what we know that matters, meaning about the future. It's what we do along the way that matters.”

There is probably no perfect way to save and invest; the key is to pick a strategy and stick with it—a good strategy you can stick with is vastly superior to a great strategy you abandon due to constant comparison with others' approaches.

“I think there probably is no perfect way to save and invest. [...] I think for most people the good strategy you can stick with is vastly superior to the great strategy that you can't stick with.”

A systematic approach using a suite of indicators or tools aligned with your investing style is superior to being bogged down in headlines and noise; know your investing style (trader vs long-term holder) and select tools that match it.

“I think I'd go back to the systematic approach. Um, you know, to to have a suite of indicators or tools. [...] to really narrow in on the tools that suit your process and your way of thinking and also your investing style. Um, to know what your investing style is.”

The biggest takeaway about dealer positioning is that it drives price movement, but supply and demand is the truly critical principle; people lose sight of this simple thing by focusing on secondary factors like fundamentals; fundamentals are part of supply/demand but must be kept in perspective.

“I think that's the biggest takeaway, right? That's part of why people kind of follow me and are interested in in in kind of what we're uh we're talking about. But at the end of the day, like I mentioned, that's one part of one critically important thing. The only thing which is supply and demand. I think so many people just lose sight of that simple little thing.”

Write down your investment decisions when you make them to create a record; reviewing past decisions against actual outcomes is the only way to learn; the worst case is when a stock goes up for reasons you didn't identify, causing you to conflate luck with skill.

“I think you need to write down what you're doing at the time that you do it because it takes, if you're a fundamental investor, it takes years really to work out whether the decision that you made actually resulted in the outcome that you thought. [...] the worst case scenario as funnly as funny as this sounds but the worst case scenario is when you get some the stock goes up but for a reason that you didn't identify.”

Valuation doesn't work on 1-3 year time horizons; over 3+ years, valuation begins to have material influence; positioning dynamics can keep assets mis-valued for extended periods; pretty charts and models that imply specific outcomes miss the time dimension—it takes months to years for outcomes to be realized.

“Valuation doesn't work under you know one two three years you know three years and beyond and you typically start to see valuation have a material influence on financial markets [...] It takes time for those things to be realized, understood, appreciated, and priced in. You know, often several months, several quarters, if not a few years.”

Investing has two components: the opportunity to win big (like Nvidia stock options) and the catastrophic loss scenario that can set you back years; avoiding catastrophic losses is as important as capturing big wins; this is asymmetric risk management.

“investing is is there's there's two parts of this. Um a lot of people focus on the one big win that will set them up for life, right? [...] Most people are focused on the positive aspect of that. You also have to be focused on the negative aspect of that. You have to avoid the catastrophic losses, right? Because that can set you back years”

The law of compounding is essential; buying and holding typically wins over time; hedging your portfolio when smart adds compounding by reducing drawdowns and allowing better emotional discipline through volatile periods.

“It's the law of compounding I mean I think it's so valuable and I think that people need to stick with that and in general you know just buy and hold I think wins out over time and and I think that if you can hedge your portfolio when it's smart that adds the compounding right because um and that could be I think a lot of times the edge that people either need or or helps them kind of mentally”

When uncertain about a position, reduce the position size in half rather than staying frozen; continue to cut if still uncertain; this prevents the freeze that leads to holding everything or selling everything, and creates a continuum of choices.

“when there's a position you have all you just undecided you're not sure if it's just a short-term move against you or you're wrong and he says if he's ever in a situation where he's not sure first thing he does is cut in half and if he's still unsure children a while later cuts it again. He says, "You know what? Before too long, you don't have a problem." And and it's a great piece of advice, really a stupendous piece of advice in my opinion, because a lot of people become frozen. They can't decide, you know, hey, I get out here, I'm going to sell right at the bottom, and then the market's going to reverse and or I hold on, it's just going to keep on going. and they they think like there's just a choice of holding everything or selling everything.”

Investors who are currently overexposed to growth stocks without earnings, cryptocurrency, or duration risk (long bond positions) should be kind to themselves, treat this as a normal part of investing, forgive themselves, and continue learning rather than retreating into inaction.

“point number one is be kind to yourself. You're only human. It's okay to be human. Don't think of yourself as a god. Don't compare yourself to lottery winners. [...] take your lumps, be forgiving, don't let them push you into inaction and continue to learn and update your models of the world.”

In addition to continuous learning, be flexible and avoid dogmatism; do not assume your point of view is correct; always look for reasons why it might not be; flexibility is a core investing virtue.

“I would say in addition to continuous learning which I said at the at the outset I would say be flexible. Don't be dogmatic. Be flexible and just don't assume that your point of view is is is the right point of view. Always look for reasons why it might not be.”

Individual investors should keep the bulk of wealth building to 'the straight and narrow' (diversified, disciplined, boring strategies), and may reserve a small 'puddle of money' for speculative plays; this separation protects core wealth.

“my advice to individual investors has always been to keep to the straight and narrow. Right? If you want to have a little a little puddle of money over here that's your more speculative play money. That's fine. I get that. I mean we all do that. That's fine. I have mine.”

The older one gets and the more expertise one acquires, the more one realizes how little one knows; this is not a sign of failure but of deepening understanding—complexity and interdependencies are vast, making overconfidence impossible.

“the older I get, I feel like the the more I realize, the less I know about all of this stuff. And so, it's this weird sort of journey in finance and economics where, you know, you typically think that like the the old guys are the ones that know everything. And I the more I I find myself becoming an old guy, the more I just sort of have realized how little I know about all this stuff because it's so freaking complex.”

It is okay to be wrong in active management; the only way to avoid being wrong is to be a closet indexer (never taking a bet), which means you never add value; taking active risk means regularly being wrong, and this must be accepted as the cost of value creation.

“it's okay to be wrong in this business really is if if you're not wrong ever which I the only one way I can think you can't be wrong is is that you're basically a closet index you and you sell yourself as an active manager, but you'll closet index you because the way you're never wrong is you never take a bet.”

Liquidity is everything; it can mean the presence of demand and funding (positive) or the removal of it (negative); when trading or positioning, you must consider your own liquidity and the liquidity of assets you own; without liquidity, nothing matters—not earnings, not fundamentals.

“Liquidity. That word is everything. Liquidity can mean the thing that spurs demand and that creates enough liquidity to keep it going. It can also mean the removal of it, right? [...] it's also important to think about when you're trading or your positioning, how liquid you are and how liquid the things you're investing. And ultimately, it doesn't matter how much demand there is today or tomorrow for something that won't ultimately have liquidity at some point.”

Diversification is humility about what you know and what you can know; the past is one sample draw from infinite possible futures involving different combinations of inflation, growth, geopolitical risk, and technological shocks; the best preparation for the unknown is diversification.

“I mean it would be diversify, right? It would be be humble about what you know and what you can know and um don't be over reliant on what you observed in the past. The past is one one sample draw from an infinite variety of potential sample draws that we might we might get in the future”

More alpha can be created in portfolio structure than in security selection; this includes both offensive approaches (return stacking) and defensive approaches (creating resilient portfolios across economic regimes).

“I think a lot of people try to find alpha in security selection and I think there's a lot more alpha to be created over time in portfolio structure. Uh and it can both be offensively through ideas like return stacking but also defensively uh in terms of how you create a resilient portfolio.”

Watching CNBC or financial media all day is a recipe for a terrible investing philosophy because it creates information overload and behavioral distortion without providing actionable insight.

“watching CNBC all day is a recipe for a terrible investing philosophy, you know. So spend less time kind of tracking markets on a minute-by-minute basis, reading everything that's happening.”

Investing is fundamentally about preserving and growing wealth, not getting rich quickly; the core mistake most investors make is chasing 100-baggers and 10-baggers rather than focusing on steady wealth preservation, which causes them to miss the foundational tenets of investing.

“Investing is about preserving and growing wealth. It's not about getting rich. [...] I would like to have a 100 bagger in my portfolio. Yes. But I shouldn't be actively looking for those things because if I look for those things, I'm going to miss the core tenants of investing.”

Valuation typically does not matter for 1-3 year horizons, but over 3+ years and especially in positioning dynamics, valuation becomes materially influential on returns.

“Valuation doesn't work under you know one two three years you know three years and beyond and you typically start to see valuation have a material influence on financial markets but generally speaking you know you something can remain over undervalued for you know several years before it really starts to get um influenced again by by by some of those positioning dynamics”

Individual investors should maintain their primary source of income (their job/profession) as the foundation for wealth building and not let investing distraction reduce their earning power, because income generation is more important than investment returns for most people.

“So, keep your focus on preserving and growing wealth, which means you need the income to create the wealth. So, if you're a doctor, go back to being a doctor. Don't spend your lunchtime looking at what stocks are doing, what your portfolio is doing. Read up some medical stuff. If you're an engineer, be an engineer first.”

Know what you own (understand holdings even if delegated to an advisor) and minimize fees and taxes; these two practices alone are sufficient for good outcomes.

“know what you own, even if it's like delegated through an investment advisor. Like I I think it's always a bad idea when the client's just like, "Oh, you're the investment guy. Deal with it." I think fundamentally you have to know what you own. Period. And then the second one is do whatever you can to keep the fees and the taxes to a minimum. Right? If you just do those two things, know what you actually own and why. I probably had to add and then keep your fees and taxes to a minimum, it's all good.”

Investing is fundamentally about preserving and growing wealth, not about getting rich quickly or chasing 100-baggers, and this core principle is increasingly lost as YouTube celebrities and media promote unrealistic get-rich-quick narratives.

“Investing is about preserving and growing wealth. It's not about getting rich. Neither get in nor get out as an investing strategy.”

The biggest sin an active asset manager can commit is becoming so focused on generating outperformance (alpha) that they neglect the core responsibility of preserving the underlying 90% of value (beta), causing catastrophic losses.

“The worst sin you can do as an asset manager is lose track of the fact you're trying so hard to put your footprint of outperformance on it that you blow the other 90%. And that is, you know, you get too bearish, whatever, or too bullish and and, you know, get it too aggressive or too conservative, probably more you can get yourself and too bearish and you miss out on on the way most of us make most of our money.”

Master the basics of blocking and tackling—fees, taxes, diversification, asset allocation—before pursuing complex strategies, because most investors fail at the basics but ignore them in pursuit of exciting complexity.

“Don't get ahead of yourself. Um, if you do a good job of blocking and tackling in the initial housekeeping, if you do a good job of those things, you'll be better than 90% of all investors because they don't do a good job of that stuff. They jump it and go straight to the complexity, the most exciting stuff, the stuff everyone else is talking about. Um, if you just do a good job of of the basics, you'll be better than than most.”

Diversification is the single most important factor for building durable wealth over time, requiring diversification across asset classes and strategy/alpha exposures, not just holding stocks and bonds.

“Diversification. It's that simple. Diversification, right? Is the ticket to uh is the ticket to building durable wealth over time. And when I emphas I emphasize that diversification, I don't mean stocks and bonds are not diversification. It's better than holding an old stock portfolio. It's better than holding one stock. But true diversification means diversifying your asset class exposures and diversifying your strategy exposure, your alpha strategy exposures, right?”

For average investors not doing this full-time, they should assume they don't have an edge; if they insist on actively managing, they need strong data skills and should hand off to professionals if they don't have them.

“I mean, to the average investor, which would would be like your guy in the the street, maybe. Uh I I think if you do this, if you don't do this like with a 100% full-time job, you need to have the right skills and you need to have the right tools. Uh meaning that you better be able to manipulate data. you better be able to understand the data and spend a lot of time um uh even in the gray areas that that you just really probably should hand the keys over to somebody else”

Building long-term wealth is not difficult; it is actually very easy, but people fail to do it because they are constantly distracted by the 'siren song' of something new, sexier, or better, which causes them to crash on the rocks (fail to compound).

“building wealth is not difficult. It's actually very easy. So why don't people do it? And the answer is that there's always a siren song of something new, better, sexier, something. And to continue on the Greek mythology there, and then people go and they crash on the rocks, right?”

Watching CNBC and financial media all day is a recipe for a terrible investing philosophy because it encourages reactive, emotionally-driven trading rather than disciplined long-term strategy.

“watching CNBC all day is a recipe for a terrible investing philosophy, you know. So spend less time kind of tracking markets on a minute-by-minute basis, reading everything that's happening.”

Timing the market via get-in/get-out strategies (betting on two moments in time) is not an investing strategy—it is gambling and no one has ever been successful doing this repeatedly over time.

“neither get in nor get out is an investing strategy. Not even close. It's just gambling on two moments in time. And there's no one that has ever been successful doing that over and over again.”

Individual investors should look at their portfolio as infrequently as possible (ideally once a year or less), because frequent monitoring increases perceived risk and triggers reactive emotional decisions due to loss aversion (prospect theory), while professionals need daily monitoring for client management.

“Look at your portfolio as little as possible. Probably probably 20 of your other people have said the same thing. Uh but that just means it's true. Um particularly for for what you call the average in investor. I think there have actually been studies on this. Uh but just intuitively, you know, whoever looks at it more loses.”

Professional asset managers typically add less than 10% incremental value beyond what diversified indexing provides, with most of that limited value coming from staying fully invested rather than making timing or selection bets.

“as a professional asset manager for many years the reality is I think we we impact just a small poor part of incremental mature. I mean probably less than 10% of the total result is going to be due to our decision if we add value. We're talking 10% or less that we add truthfully because the reality is you take in a pot of assets and the vast majority of it is already spoken for.”

Simplicity in portfolio construction is superior to complexity—use at most a few diversified funds (balanced index fund, total stock market, international, reserves)—because simpler portfolios are cheaper, less taxing, and leave more time for the rest of life.

“Simpler the better. Honestly, if you can do it with two funds, do it with two funds. I mean, you don't need any more than a balanced index fund and a tax deferred portfolio and then in your taxable portfolio if you're going to have stock in there, total stock market, total international and a you know, something for a reserve fund of some sort. But I mean, the absolute simpler you make it, the better it is for you, the better it is for your family, the cheaper it is, the less taxing it is, and the more time you have to spend doing the things that you enjoy doing”

Pretty charts and patterns (valuation setups, leading indicators) create false confidence in timing; realizing such setups takes months or quarters or years, not days, and this timing delay is often overlooked.

“It takes time for those things to be realized, understood, appreciated, and priced in. You know, often several months, several quarters, if not a few years. I, you know, the older I get, I feel like the the more I realize, the less I know about all of this stuff.”

Know your circle of competence and don't try to pick single stocks unless you're a professional; most taxi drivers will already have heard the stock story by the time you hear it.

“Know what you know and know what you don't know. And if you you know make your money, you're in some kind of certain function or specialty in the world, go and do that. Uh it's unlikely that you're a professional stock picker that could pick single name stocks. the time you've heard about the story of any stock by the taxi driver, the story is probably already over.”

Control your ego in investing, especially in group settings, as ego-driven positioning or contrarianism for its own sake leads to poor decisions.

“try to control your ego, which is against your nature, but um try to control that. It was really hard to especially when you're in a group of people go and um you know not every one of all them be careful about that”

Many successful investors in other fields come to investing with unrealistic expectations (e.g., 15% annual outperformance vs. S&P 500), not understanding how difficult and competitive active management is.

“he had made a lot of money in another industry, a lot of money. He was very successful and he um actually asked me to run his money and his expectations were to beat the market by um like the hurdle rate was 15% above the S&P 500 um every year or something like that and he had just started out and um I had a pretty serious conversation with him that this is an unrealistic goal and and why and so that's kind of the thing I see more most often with I would say the average investor is just a lack of an appreciation for how hard this game is”

Compounding and buy-and-hold strategies outperform over time, and hedging when appropriate adds to compounding by reducing drawdowns without sacrificing upside, allowing investors to remain psychologically invested through volatility.

“it's the law of compounding I mean I think it's so valuable and I think that people need to stick with that and in general you know just buy and hold I think wins out over time and and I think that if you can hedge your portfolio when it's smart that adds the compounding right because um and that could be I think a lot of times the edge that people either need or or helps them kind of mentally because again it's hard to just sort of say I'm going to buy and hold through a 20% decline”

Core principles for investing: make sure everything is based on evidence, not opinion (e.g., not Jim Kramer); maintain high diversification; don't take more risk than your ability/willingness/need to take; understand that risk assets have long poor performance periods; never engage in 'resulting' (judging decisions by outcomes rather than process).

“I'd go back uh to my core principles. Make sure everything you're doing is based on evidence, not Jim Kramer's or anybody else's opinions. Uh, and make sure that your portfolio is highly diversified. You're not taking more risk than you have the ability, willingness, and need to take to remember that all risk assets go through long periods of poor performance. So that's a reason why we diversify and never engage in resulting. Don't judge the quality of your decision by the outcome. Judge it by the quality of your process.”

If you don't do this (active investing) as a 100% full-time job, you need right skills and tools (data manipulation, understanding data); otherwise, you should hand the keys over because it's not an easy game, and most people lack appreciation for how hard it is.

“if you don't do this, if you don't do this like with a 100% full-time job, you need to have the right skills and you need to have the right tools. Uh meaning that you better be able to manipulate data. you better be able to understand the data... you should hand the keys over to somebody else... it's not an easy game. I see so many people... lack of an appreciation for how hard this game is”

Know your competencies: if you are not a professional stock picker, understand your skill limitations and focus on your primary specialization; diversify rather than placing all eggs in a single basket.

“Know what you know and know what you don't know. And if you you know make your money, you're in some kind of certain function or specialty in the world, go and do that. Uh it's unlikely that you're a professional stock picker that could pick single name stocks. the time you've heard about the story of any stock by the taxi driver, the story is probably already over.”

As a professional asset manager, the reality is that active management adds less than 10% to total portfolio returns; the vast majority of returns come from asset allocation and market movement; the worst sin is to focus so hard on outperformance that you blow up the core portfolio.

“the reality is I think we we impact just a small poor part of incremental mature. I mean probably less than 10% of the total result is going to be due to our decision if we add value. [...] The worst sin you can do as an asset manager is lose track of the fact you're trying so hard to put your footprint of outperformance on it that you blow the other 90%.”

Finding your investing methodology takes time and iteration; reading is a great exercise for initial exposure, but you must whittle it down into a personal methodology over time—you cannot be simultaneously an Elliott wave strategist, point-and-figure chartist, and value investor.

“it takes time to sort of whittle that down into a methodology because uh you know, you can't be an Elliot wave um strategist and a point and figure chartist and um you know, a sort of a valueoriented investor all at the same time necessarily, right? you have to kind of find your your uh place in the investing world.”

You must have some philosophy that governs your investing; without a governing philosophy, you are just flapping like a fish out of water; the philosophy does not have to be buy-and-hold, but you must have one.

“you have to have some sort of philosophy that governs you, right? And if because if you don't have that, then you're just then you're just flopping like a fish out of water. So some people get there quicker than others. Some people never get there.”

Picking market tops is difficult because if you pick the top, you must also pick the bottom; for most investors, this is impossible; therefore, focus on buy-and-hold with dividend stocks rather than market timing.

“to make money in the markets by picking tops uh is a is a is tricky because then you've got to pick the bottom.”

Control your ego in group settings where everyone is discussing ideas; overconfidence leads to poor decisions; the ability to admit 'I don't know' and suppress the urge to have an opinion on everything is a key discipline.

“try to control your ego, which is against your nature, but um try to control that. It was really hard to especially when you're in a group of people go and um you know not every one of all them be careful about that”

Buffett's parable: imagine a ticket you can only punch 20 times in your life for 20 buys, and you can never sell; taking this mentality to heart in investing would lead to better outcomes than assuming you can actively trade.

“Buffett has a great line, I'm paraphrasing here, something like, "Imagine if you had a ticket you could only punch 20 times in your life and there the 20 buys you can make and you can never sell." And if you take something like that as your mentality, I believe that you will do better with all of your investing than if you didn't.”

The speaker had a wealthy client who made money in another industry and wanted to beat the S&P 500 by 15% annually; this is an unrealistic expectation revealing a common misconception about how hard professional investing is.

“I see so many people who uh I had a a guy one time, I'm going to not describe too much about him, but he had made a lot of money in another industry, a lot of money. He was very successful and he um actually asked me to run his money and his expectations were to beat the market by um like the hurdle rate was 15% above the S&P 500 um every year or something like that and he had just started out and um I had a pretty serious conversation with him that this is an unrealistic goal and and why and so that's kind of the the thing I see more most often with I would say the average investor is just a lack of an appreciation for how hard this game is”

Never engage in resulting—judging the quality of decisions by outcomes rather than process—because outcomes have luck components; maintain your process even during bad luck periods.

“never engage in resulting. Don't judge the quality of your decision by the outcome. Judge it by the quality of your process. And if your process is good, it's likely you just had a period of bad luck and you need to stick with your process.”

Know what you own (understand your holdings) even if delegated to an advisor, and keep fees and taxes minimal, because these two factors determine the vast majority of wealth building outcomes.

“That one's actually pretty easy. I would just say know what you own, even if it's like delegated through an investment advisor. Like I I think it's always a bad idea when the client's just like, 'Oh, you're the investment guy. Deal with it.'... do whatever you can to keep the fees and the taxes to a minimum. Right?”

Neither 'get in' nor 'get out' is an investing strategy; market timing based on two moments in time is gambling, and no one has ever been consistently successful doing it over and over again.

“neither get in nor get out is an investing strategy. Not even close. It's just gambling on two moments in time. And there's no one that has ever been successful doing that over and over again.”

Owning a portfolio should feel like owning a collection of businesses rather than trading sardines (securities); this mindset shift prevents performance chasing and reduces selling pressure, leading to superior long-term outcomes.

“Well, it would be that you own a business. You own a business and and this idea that you own a trading sardine uh instead of a business leads to so much bad behavior.”

Simpler is better; if you can do it with two funds (balanced index + tax-deferred), do it; the absolute simpler you make investing, the better it is for you, your family, costs, taxes, and your time for other activities.

“Simpler the better. Honestly, if you can do it with two funds, do it with two funds. [...] the absolute simpler you make it, the better it is for you, the better it is for your family, the cheaper it is, the less taxing it is, and the more time you have to spend doing the things that you enjoy doing”

The 1970s and 1960s investors who survived high inflation and stagflation did so by holding gold, commodities, inflation-indexed bonds, and real assets—not stocks and bonds alone; today's investors have become desensitized to true diversification because they've only seen assets work one way.

“talk to people who invested in the 70s and the 60s and talk to them about how they survived those dynamics uh without you know uh facing huge painful draw downs in particularly in real terms in their wealth and the way that they did that was by holding a lot of different assets gold commodities uh inflation index bonds”

For stock investors, the simple recommendation is: buy dividend-yielding stocks, put them away, and sleep well; good companies are better, dividend growers are better still, but this is the easiest path to returns.

“Oh, I mean that's a layup. Uh you know, for stock investors, uh buy dividend yielding stocks, put them away. Uh you know, obviously good good companies are better than that. Dividend growers are better than that. And uh you you're going to get a lot of a lot of sleep.”

Charlie Munger's core advice to 'get out of your own way' means minimizing self-inflicted errors through psychology; avoiding the natural propensity to make mistakes requires mastering a set of important ideas and disciplining behavior.

“I think I would say get out of your own way. Um he he didn't he didn't put it exactly that way, but but he could have. It's it's a mongerist mongerism like get out of your own way. Um but but it comes out of his emphasis on the psychology of uh investing of trying to avoid the natural propensity to make mistakes”

Diversification is protection against bad luck, not protection against ignorance; education and research protect against ignorance, but everyone experiences bad luck, so diversification is universally necessary.

“I think education and research and study that's protection against ignorance. Uh, diversification is protection against bad luck. And everyone has bad luck at some point in their career. Uh, and that's really the reason that diversification um matters.”

If you concentrate investments in one asset class or strategy style (deep value over the last decade), you create style concentration risk that can lead to underperformance even if asset allocation is theoretically correct.

“But I think we should also think about how those investment decisions are being made and when they're being made, right? Uh if you got your asset allocation correct, uh but you put all your equities into deep value stocks over the last decade, you know, you've sort of lagged behind equity markets. So your how decision wasn't necessarily well diversified.”

Chase performance—the behavior of buying what's been doing well and selling what's been doing poorly—is endemic to human nature but ruins investment returns, making anti-performance-chasing discipline the core requirement for success.

“Dchase performance Um, it's endemic. It's innate in in the human uh uh psyche. The notion of um something's hurt me, get me out of here, something's been good for me, given me profit, given me great joy. I want more of that. This is all very much human nature. It's a horrible way to invest.”

Avoid catastrophic losses as assiduously as pursuing big wins, because a catastrophic loss can set you back years and eliminate the compounding benefits of decades of gains.

“Investing is there's two parts of this. A lot of people focus on the one big win that will set them up for life. You also have to be focused on the negative aspect of that. You have to avoid the catastrophic losses, right? Because that can set you back years.”

Base rate reasoning is demonstrably underutilized despite its proven power in helping people make better decisions across investing and life.

“It's remarkable how underutilized this concept is now withstanding its demonstrable power.”

Be somewhat skeptical of consensus when everyone agrees something bad is coming; look around and see if you actually see doom, because consensus pessimism often contains opportunity.

“being somewhat skeptical about the consensus uh when when when everybody is so convinced that things are going to go wrong uh ask yourself you know try to think about what what might might go right and again look look around you you know you know uh what do you see do you see doom and gloom or do you see some some optimistic things going on out there?”

Modern investing offers unprecedented access to low-cost, tax-efficient strategies (ETFs) that were previously available only to wealthy individuals and institutions, making individual investors the beneficiaries of democratized financial markets.

“it's probably never been a better time to be an individual investor in terms of the strategies and products and tools we have available. I mean, if you think about some of the strategies that are now offered in a taxefficient ETF that were only available to rich individuals or institutions or hedge funds back in the day and individuals can now use these same strategies at for pennies on the dollar in terms of costs.”

Looking at your portfolio as little as possible is optimal for average investors; frequent observation increases perceived risk and induces loss aversion, leading to poor decisions, while less frequent monitoring preserves emotional discipline.

“Look at your portfolio as little as possible. [...] Probably probably 20 of your other people have said the same thing. Uh but that just means it's true. Um particularly for for what you call the average in investor. I think there have actually been studies on this. Uh but just intuitively, you know, whoever looks at it more loses.”

Supply and demand is the fundamental driver of returns—how many buyers vs. sellers—and this simple dynamic is obscured by overemphasis on second-order factors like fundamentals; liquidity is the critical operational concern.

“The only thing which is supply and demand. I think so many people just lose sight of that simple little thing. How many buyers are there and how many sellers are there? We obfiscate this by thinking about second order factors like fundamentals. Fundamentals matter. The cash flow corporation is part of that supply and demand. But we lose sight of how many buyers versus sellers are there ultimately.”

Risk assets go through long periods of poor performance; this is expected and normal, which is why diversification is essential and why you should not judge your portfolio's quality by its recent returns.

“Make sure that all risk assets go through long periods of poor performance. So that's a reason why we diversify and never engage in resulting.”

The most important thing to being a successful investor is booking gains—realizing profits and never being afraid to do so—because you cannot make money unless you actually take profits.

“The most important thing to being a successful investor is booking your gains. That's it. Booking your gains. Also secondarily is also containing your losses. But you cannot make money unless you actually make money. And you do so by booking gains. Never be afraid of it.”

Portfolio structure and allocation decisions (the 'what' and 'how' and 'when' dimensions) offer more alpha-generation opportunities than security selection, including through return stacking offensively and resilient diversification defensively.

“I think a lot of people try to find alpha in security selection and I think there's a lot more alpha to be created over time in portfolio structure. Uh and it can both be offensively through ideas like return stacking but also defensively uh in terms of how you create a resilient portfolio.”

The most important thing in being a successful investor is booking your gains; never be afraid to take profits; you can always buy again tomorrow; containing losses is secondarily important.

“The most important thing to being a successful investor is booking your gains. That's it. Booking your gains. Also secondarily is also containing your losses. But you cannot make money unless you actually make money. And you do so by booking gains. Never be afraid of it. You can always go back and buy it again tomorrow.”

Get actual base rate statistics for asset classes (adjusted for fees, taxes, transaction costs, and net returns), which often look quite different from convenient marketed portfolios; this 'good housekeeping' separates winners from the rest.

“get to the actual base rate statistics first... most people put their money in equities because they compound at 10 11% a year... If you do that for all asset classes... it'll look quite a bit different than some of the, you know, convenient portfolios that are out there available for people... I consider that, you know, good housekeeping.”

Think long term; compounding is the primary engine; if you save from age 25-30 and let it grow for 40 years, the early savings have disproportionate impact; the earlier you start, the more time compound interest works.

“Think long term. You know, it's it's it's it goes back to the compounding question. It's it's you know I mean just do the basic math like like I was reading about a hedge fund the other day and it was guys who were thinking in college I save $1,000 this this semester and I invest it how much could it be worth in 40 years right”

Deep skepticism about obvious market patterns or clear-cut distinctions is warranted because what appears obvious in investing is usually false, and the feeling of certainty should trigger wariness rather than confidence.

“treat everything that you see out there with uh a pinch of salt. and and really try to validate things and also like if anything ever seems obvious in investing probably not true like if anything like so such a clear-cut distinction that it's like obviously I should be all in definitely not the case um and in fact like that feeling should be worries so a deep deep skepticism is probably the biggest lesson I can I can impart”

Being invested consistently is very important for average investors; the gap between an investing physicist and an expert investor is smaller than the gap between not investing and investing consistently.

“for your average investor Yeah. you know being invested sticking with it is is very very important. Um, for the average investor who you knew would have known more than I did as is a physics major when all I knew was physics, I would say, you know, make your plan, stick with it, you know, know that you can take what's coming uh diversify and uh diversify across different sources of risk”

Patience in holding positions through normal volatility, resisting media noise, and tuning out financial intermediaries who profit from transactions are critical skills, because most money is made by being 'along for the ride' of market appreciation, not timing.

“I would say it's patience, you know, patience. I know like when I was learning investing in all my 20s and 30s, I was much more jittery about things like, you know, company reports a bad quarter, stock starts falling, you know, I'd get get really antsy. I want to get out of it, you know, and uh and I think if you could if there's one thing I could pass on, it would be it would be that just, you know, when you buy something, be a little be more careful about what you buy. be sure you think that you won't own it for a long time and then let it leave it alone.”

Being wrong is acceptable in active management; the only way to never be wrong is to be a closet index (taking no real bets), which generates no alpha but also no value for clients, so risk-taking is necessary for returns.

“it's okay to be wrong in this business really is if if you're not wrong ever which I the only one way I can think you can't be wrong is is that you're basically a closet index you and you sell yourself as an active manager, but you'll closet index you because the way you're never wrong is you never take a bet.”

The single most important attribute for long-term investing success is patience; patience requires tuning out financial media and Wall Street noise that actively incentivizes transactions; this selective filtering is harder than buying/holding but essential.

“I would say it's patience, you know, patience. [...] being patient is being able to tune out all that [financial media and Wall Street]. And not the easy, but that would be, if I could tell the average investor one thing, that would definitely be it.”

Long-Term Capital Management (LTCM) blew up because they were short illiquid things against long liquid things, positioning themselves for liquidity mismatch; in a leptocritic (fat-tailed) market, illiquidity is catastrophic.

“There's a reason the name the the word long-term is in uh long-term capital management. I can't stress this enough. Long-term capital management blew up because they were short puts that were longdated against things that are short. They were short illquid things versus things that were liquid.”

Executing the basics correctly—diversification, tax efficiency, low fees, base rate analysis—puts you ahead of 90% of investors because most skip the fundamentals to pursue complexity and excitement.

“if you do a good job of blocking and tackling in the initial housekeeping, if you do a good job of those things, you'll be better than 90% of all investors because they don't do a good job of that stuff. They jump it and go straight to the complexity, the most exciting stuff”
