Economic Time Bomb: The Silent Threat of Passive Investing Exposed by Michael Green

The passive investing creation-redemption process involves hidden trading activity: when money enters a target date fund, it's initially allocated to futures, then index arbitrage traders recreate those futures using individual stocks, generating trading volume that is 'technically not passive' but entirely tied to passive flows and unrelated to fundamentals.

“if I choose to put money into my Vanguard um Target a fund that's a single flow that goes in and so it doesn't represent a ton of trading activity but actually a remarkable amount of trading activity is happening behind the scenes to facilitate your index investment typically that money going to a Target date fund will do something like allocate initially into Futures in order create the Futures there has to be index Arbitrage Futures Arbitrage traders who are willing to recreate those Futures with the single names that is trading that is not technically passive but is tied to passive Dynamics within ETFs anytime you buy an ETF you have to go through the creation Redemption process that trading activity is technically not passive but very much tied to that process and again has nothing to do with fundamentals”

Passive flows into 401k and IRA accounts automatically buy market-cap-weighted indices, creating an asymmetric force: contributions from employed workers always fuel buying, but withdrawals only come during market strength, so markets can sustain elevated prices as long as employment and net 401k contributions remain positive.

“as long as that flow of funds supports buying activity that pushes prices higher none of the fundamentals actually really matter it's when those layoffs actually begin to mount it's when that narrative begins to change it's when those flows begin to move in the opposite direction that you'll see markets correct”

Passive investing strategies are simple algorithms that buy when cash is contributed and sell when cash is withdrawn, with no thought process or fundamental analysis involved, which removes economic signals from markets and converts them from leading indicators to lagging indicators.

“the growth of passive strategies which are really just simply algorithms that involve anytime you put money into your 401k or into your IRA through passive Vehicles it becomes a really simple algorithm that simply goes did you give me cash if so then buy did you ask for cash if so then sell since there's no thought process that's going into that unfortunately that means we're robbing the markets of the economic signals that they would have historically provided and changing them from leaning indicators to what I would describe as lagging indicators”

Young people can no longer afford homes, driving an explosion of intergenerational living and creating an 'Italianization of America' where homes are passed down within families rather than sold on the market, destroying price discovery and creating trapped, unprofitable real estate portfolios.

“many of your listeners would actually Echo that they're seeing their own children unable to afford homes that's caused an incredible explosion of young people that live with their parents and are increasingly abandoning the idea that they would ever move or get their own home effectively resigning themselves to what I call the italianization of America where you have a very similar phenom on in Italy very small population growth to negative population growth children live with their parents the home never gets sold in the public market it gets passed down as compared to being sold and as a result price Discovery really doesn't exist in a place like Italy you have homes that are very you know difficult to buy if you want to buy a high-end property but you have an increasingly an increasing number of decrepit properties that you could buy for a dollar for example”

Nvidia's 77% gross margins on GPU products are unprecedented in the hardware space and are instead consistent with extreme value-added services like software, indicating Nvidia has a near-monopoly pricing power on AI chips that allows it to extract outsized returns.

“they clearly have come up with products and developed products that not only do they have a unique uh effectively a monopoly on right they have a unique product others do not have currently with the chips that are used for the large language models and what we were increasingly referring to as AI right um because they have that lock they're able to charge ex extraordinary prices the gross margins that they're creating off of those products are nearly unprecedented in the hardware space so I think last quarter they printed something like a 77% gross margin those are levels that are far more consistent with extreme value added Services things like software for example”

Nvidia paid almost no taxes over the prior four years ($87 million total) despite becoming the world's third most valuable company, exemplifying corporate tax avoidance that generates public frustration and raises questions about the fairness of a tax system that lets mega-cap companies contribute nothing.

“Nvidia for example which is just become the world's third most valuable company paid almost no taxes over the prior four years that's really an extraordinary statement when you think about the success of a company like Nvidia I believe their total tax bill over the last four years until this last year was only about $87 million in taxes”

Much of the recent federal debt increase was driven by wasteful giveaways like PPP loans and the Employee Retention Credit, which provided windfalls to business owners in an economy that turned out stronger than expected, disproportionately benefiting those with lawyers to navigate the programs.

“a lot of the increases in debt that you're describing that occurred over the last several years unfortunately we're just a giveaway um in many situations right things like the PPP loans which theoretically allowed allowed companies to continue to employ people um but effectively just covered costs in an environment in which the economy ended up being much stronger than people had anticipated and put providing a windfall for business owners the employee retention credit turned into an outright fraud program initially budgeted to cost $55 billion ultimately costing several hundred billion dollars”

Commercial real estate is suffering from high interest rate exposure; multifamily properties are experiencing severe performance deterioration, making regional banks and small commercial real estate lenders vulnerable to cascading defaults and forced liquidations.

“we are seeing commercial real estate suffer we are seeing that get worse...we're seeing that within commercial real estate we're beginning to see that within multif family residential”

JDS Uniphase still exists and operates profitably as a niche networking company under a different ticker (VIAV), demonstrating that failed dot-com companies didn't disappear but rather consolidated into smaller profitable operations, which could be a model for how overproduction cycles resolve.

“is that company still around it is no it's a company that still exists it's actually uh trading under a different ticker now I believe it's viav is the ticker um they continue to be a a reasonably good networking company that's operating profitably and selling Niche products it didn't go away and I I think that's important for people to understand”

If oil prices rise to $100/barrel in an economy where household budgets are already stretched by inflation and rising rates, people will be forced to cut discretionary spending on travel, vacations, and dining, cascading into earnings misses across tourism, hospitality, and leisure sectors.

“we're actually you know as much as we're worried about oil prices going to 100 bucks the reason it matters now is because people's budgets are so stress stressed right it's a combination of the fact that they have um less disposable income because other prices have risen right so while I'm not particularly worried about continued inflation one of the reasons why I'm not that concerned about it is because I understand that household budgets are so stretched that they simply can't afford to pay that next dollar and so if we actually look at a situation like oil prices going higher unfortunately that means that you're likely to see people forc to spend less elsewhere”

Even though Japan and Germany are entering recession, their stock markets are at all-time highs because foreign capital is being reinvested in those markets through index futures and index investing, which mechanically reinforce momentum without regard to deteriorating fundamentals, exemplifying how passive flows disconnect prices from reality globally.

“even as Japan and Germany are entering recession their stock markets are at alltime highs and that's because we're plowing proceeds into those markets chasing the performance so even as they're underlying economies deteriorate and they face increasing domestic stress Germany for example is very actively seeing protests and demonstrations that's actually unfortunately the same type of phenomenon that we're talking about here where the money that is going into Germany or into Japan is increasingly going in through things like futures or index investing that is simply reinforcing momentum characteristics and markets that didn't exist before”

The 1987 stock market crash was caused by an imbalance in sell orders vs buy orders for S&P futures, and similar conditions exist today but with greater systemic risk because passive investing has saturated the market—Baby Boomer retirements will reverse net flows to negative, creating an imbalance that triggers a correction from which recovery is uncertain.

“1987 was exactly this type of dynamic it was actually caused by an imbalance in orders to sell S&P futures versus buy S&P futures if you were to see something like that happen today it would manifest itself similarly but the challenge that you now have is that the conditions are in place in which the next dollars in are likely to be less than people think they are right we're looking at a situation where basically everybody is into the pool everybody is participating in the stock market and now we're suddenly facing the retirements of the Baby Boomers which means that the net flows actually threaten to turn negative that imbalance is what shows up as a market crash whether we recover from it is a totally separate question”

Unemployment rates are low not because people are finding work, but because the labor force is shrinking due to non-participation; full-time employment has actually fallen over the last year, and youth and minority unemployment are rising significantly, indicating headline unemployment masks real labor market deterioration.

“there's two ways unemployment rates can be low an unemployment rate can be low because many people are finding work and there's lots of opportunity that exists unemployment can also be low because there's simply not many workers entering the labor force unfortunately we're facing the second one much more than we are the prior one and in fact if if we look at things like full-time employment that's actually fallen over the last year we've had negative job growth in terms of full-time employment we're increasingly seeing Rising unemployment rates for um many areas of the market that had benefited and had very strong gains in uh the past couple of years minority employment is is beginning to rise we're beginning to see youth unemployment rise fairly significantly”

Real GDP growth for 2023 was approximately 2.5% in real terms, not the 5% headline figure, which conflates inflation with actual growth and masks that expansion is driven by government sector expansion while the private sector grows slowly or contracts.

“the 5% that you're referring to as a nominal number right so that's a combination of inflation and the real growth rate if we look at what the real growth rate for GDP was for 2023 across the entire year I believe it was around two and a half percent in real terms um that's above potential when we consider the rate of of Labor Force growth but it's not a particularly strong number um at the same time where that growth is coming from I think is actually important as well and what we've seen is we've seen an expansion of the government sector as the private sector continues to grow very slowly and in many situations contract”

Markets failed to signal the COVID-19 crisis until the global economy was shut down, then reacted extremely negatively, demonstrating that passive-induced lag in price discovery allows real economic dangers to build undetected—a pattern Green believes is repeating today with economic weakness masked by positive market performance.

“we experienced this firsthand when we went through the covid Dynamics almost all active managers anyone who actively followed financial markets was aware of the impending Health crisis that was emerging and yet markets didn't respond until we literally got to the point that we shut down the global economy and then they responded in a fantastically negative way”

Hiking interest rates under conditions of very high debt levels is contractionary in theory but actually increases income inequality in practice: those with cash in savings accounts earn higher interest (income boost), while those who need to borrow (young people buying homes) find borrowing unaffordable, creating a K-shaped economy.

“hiking interest rates is perceived as contractionary right the idea behind it is that it's going to slow economic activity unfortunately that model breaks down under an environment in which you have very high levels of debt so what we've actually done is increased the incomes of those Americans who already have money who have money sitting in a money market account or who have money sitting in a bank account they're experiencing higher incomes than they would have historically because of this increase in interest rates at the same time those who need to borrow to go out and purchase I.E those who are starting their lives out are finding that simply unaffordable and so we're actually seeing what I what what's been accurately described as a k-shaped economy those who are well position and have in you know have cash available to them are doing extraordinarily well those who are struggling and trying to get their first step on the ladder are finding it increasingly hopeless”

Nvidia's growth trajectory parallels the dot-com cycle (companies like Cisco and JDS Uniphase grew at similar or faster rates 1999-2001) and faces similar risks: overproduction, inventory write-downs, and price collapse when demand saturation hits, though Nvidia's profitability has been higher and the period longer.

“many people have drawn comparisons to the dotc cycle and I think there's actually a lot of validity to that we saw similar growth rates for Cisco or even faster growth rates for companies like JDS unase that were in specialized areas of the market in that 99 to 2001 time period um this is similar it's just it's gone on longer and is occurring at a scale and a level of profitability that I think surprises many people”

The US retirement system shifted from company-managed defined benefit pensions (professional managers who struggled to deliver returns) to defined contribution 401k plans where individuals manage their own assets; individuals then defaulted to passive 'buy the whole market' strategies because they lacked confidence, making the American worker 'the product' rather than the beneficiary of thoughtful capital allocation.

“our retirement system in the United States stes has developed it used to be that a company would provide a pension plan for you we discovered that those professional investors running pension plans were incapable of managing the assets to deliver the the desired levels of retirements we got rid of the defined benefit plan and replaced it with a defined contribution plan you as an individual were expected to be able to manage your assets to deliver returns that couldn't be done by the companies that in turn then LED people to say well I don't know what I'm doing so I'm just going to buy everything in the market right now everybody is actually presuming that somebody else is doing the work this is very much like the internet phenomenon in Web 2.0 where if you're not paying for the product right you're not paying for manager you're not paying for an asset allocator you're effectively just using historical data that is available to everybody to build a program that would have worked in the past if you're not paying for that service in Internet words we you know internet descriptions we say if you're not paying for it you're the product and that's really unfortunately what's developed is that the American retiree the American worker the American saver has become the product rather than a thoughtful process of capital allocation”

Markets are narrowing into a small set of 'story stocks' (the Magnificent 7 collapsing into the Magnificent 4 and beyond) analogous to the Nifty Fifty of the 1970s and the dot-com darlings of the 1990s, with passive inflows forcing money to chase these crowded trades regardless of fundamental deterioration elsewhere.

“just like the 1990s and today we're seeing a market that is narrowing it is focusing itself on the companies where we have adopted a narrative that says these are almost the story stocks right the nifty50 from the 1970s the just don't sell us JDS UNIF phases or cisos which were the you know selling the pick and shovels to thec site ccle we're seeing the same thing happen now where I would argue the mag 7 is you know the Magnificent 7 is beginning to narrow into the Magnificent four that ultimately will end up being something less than that but that narrowing itself is indicative of money that is flowing in and increasingly just trying to find some reason to be invested”

Rising auto loan delinquencies among young people reflect that those who purchased vehicles at inflated prices can no longer afford payments; as more households hit their breaking point and declare bankruptcy, consumption collapses overnight because debtors lose access to credit, apartments, mortgages, and auto loans.

“we're clearly seeing it in the rising default rates for many individuals in things like young people with auto loans where they went out and paid top price for those vehic Vehicles now they're suddenly recognizing that they just don't have the funds to pay those off we're seeing incredible increases in delinquency rates for young people on auto loans credit cards Etc um when people hit the breaking point their spending patterns change radically right the day before bankruptcy you probably still go buy that cup of coffee and in fact you probably get an avocado toast because you know you about to file bankruptcy and this is going to be the last avocado toast you can buy on a credit card the day after bankruptcy you can't spend on any of that stuff you can't qualify to have get your own apartment you can't qualify for a mortgage you can't qualify for an auto loan and so your pattern of behavior changes radically”

Approximately 85% of all passive investors are placed through their employment into target date funds that they never adjust, which represents a form of discipline but is actually inattention—passive workers are set-and-forget participants who will face the consequences when flows reverse.

“something like 85 percent of all investors are placed you know through their employment into something like a Target date fund and never changed that they just never changed that now there's something to be admired about that discipline but let's be honest it's not really discipline it's in atttention”
