There have been many ridiculous statements made about passive investing over the years. None have garnered as much media attention as hedge-fund manager Michael Burry’s claim that passive investments such as index funds and ETFs are the next bubble. He said these index-tracking investments are “inflating stock and bond prices in a similar way that collateralized debt obligations did for subprime mortgages more than 10 years ago.”
“When the massive inflows into passive vehicles reverse, it will be ugly.” – Michael Burry
Such a bold claim from someone who correctly called the subprime mortgage crisis is certainly cause for concern. But when you peel back the layers, Burry’s statement doesn’t make much sense. Looking for a smarter take than that, I reached out to Erika Toth, a Director of ETFs at BMO Global Asset Management, to explain why passive investing is not in a bubble.
Take it away, Erika:
Debunking Michael Burry’s Passive Investing Bubble Claim
I may not have had Christian Bale play me in a movie, and I did not make millions during the financial crisis, but I have spent years now studying market structure and eating, sleeping, and breathing ETFs. Burry’s comments that sparked a media frenzy (and let’s all agree that the financial media loves to sensationalize) echo some of the most common myths and misconceptions I have encountered on the ETF wrapper.
This “passive investing is in a bubble” argument assumes that all the money invested in passive indices has flowed in to the same indices, that hold the same stocks, in the same proportions. However, there are many different types of passive funds and ETFs: some track the S&P 500, some track indices built around low volatility, quality, value, or momentum filters. Some track specific sectors.

Different investors have different investment objectives and motivations. Some want to buy the market. Some require higher cash flow. Some require lower volatility. Some are searching to exploit market inefficiencies in order to generate alpha. Pension funds have to make sure their liabilities are funded. Some investors are searching for companies that meet the highest environmental, social, and governance standards. Some require certain tax efficiencies or credit qualities to be met. Therefore, it is impossible that the entire world’s stock and bond markets would move to 100% passive.
It’s also important to note that individual stock ownership by households (domestic and foreign) accounts for just over half of the equity market: the largest share, by far. Mutual funds (active and passive) own about 24%; ETFs own about 6%. Pension funds would represent about 10% (government and private); and about 8% is owned in other vehicles such as hedge funds. (This is according to data put together by the Federal Reserve Board: see below).
ETFs themselves are too small a slice of the overall pie to be able to cause a crash in the prices of the stocks they hold; they simply reflect those prices. Those statistics are for the equity market. ETF ownership of the global bond market is even smaller, roughly 2-3% by most estimates.
The theory that everyone will run to the exits at the same time in the event of a major downturn is incorrect, and 2008 is a good example of that. My favourite example comes from Ray Kerzehro, who is Director of Research at independent firm PWL Capital, in the still-very-relevant white paper he published in 2016.
Kerzehro examines how high yield bond ETFs in the U.S. traded during the height of the financial crisis. Keep in mind that high yield bonds are NOT a large cap equity index made up of the largest and most liquid stocks in the world: they are a riskier asset class of lower credit quality and are less liquid as well. So, even in this riskier and less liquid asset class, there was actually no massive exodus from those ETFs.
What happened is that trading VOLUME actually spiked. Buyers & sellers of the ETF units had different views for different reasons, and the ETF structure actually provided price discovery to an asset class where many of the underlying bonds had gone no-bid. Continue Reading…
