A Ridiculous Question on Passive Investing | ETF Trends

By Toroso Investments

Over the past month, the financial media has once again engaged in ETF fear monger and a constant barrage of articles about the “passive bubble.” This renewed focus and blame-game was sparked by a few out of context quotes from Michael Burry in a Bloomberg article:

A number of ETF Think Tank members have encouraged us to enter the debate considering we have covered the passive bubble discussion many times before with data from our research tools.  Last fall we looked into the most over-owned and under-owned securities by ETFs in our “Politics of ETF Influence” research note: https://torosoam.com/blog/the-politics-of-etf-influence/.

Burry, Beets, Battlestar Galactica

In short, we believe the question of whether ETFs are causing a bubble is ridiculous and reminiscent of the absurdly funny scene from the iconic comedy “The Office”.  A must watch below.  Our ETF Think Tank research shows that the data doesn’t support the narrative, furthermore we contend that the transparency benefits of ETFs are not the primary cause of bubbles but rather are exposing bubbles created by herd investing or government intervention.

The self-referenced absurdity in this Office scene is inherent in the question of passive bubble creation.  Not only is the question ridiculous but the entire conversation is without context and “facts” are assumed or declared without evidence. Take the assertion, within the Bloomberg/Burry article, that the passive wave of assets is somehow responsible for the mispricing of Gamestop $GME because it is not in the major indexes. We immediately discovered using our ETF Think Tank ETF Ownership Influence App that $GME is actually extremely over-owned by ETFs relative to the average US equity.

A number of other ETF nerds have furthered this conversation by bringing context and facts to the discussion:

Fact: Burry eats Beets

Simply declaring something a fact, doesn’t make it true. Further, linking two coinciding events does not prove causality. That is the best way to describe the second Bloomberg interview with Burry which focuses on passive investing’s effect on Japanese equities: https://www.bloomberg.com/news/articles/2019-08-28/the-big-short-s-michael-burry-sees-a-bubble-in-passive-investing

This interview expresses our biggest concern with ETF fear mongering: the linking of government-fueled dislocation in market prices to a passive scapegoat. Essentially, ETFs should be applauded for their transparency, which allows investors to identify bubbles rather than be blamed for providing access in the first place. At the ETF Think Tank, we believe, ETFs can identify bubbles, ETFs can provide investors ways to access bubbles and, in some cases, inflate valuations in small sub-sectors or factors. The passive-aggressive headlines of “CDO” like cotangent obscure investors from the facts, benefits and true pitfalls of index investing.

We thought we would also share some thoughts from ETF Nerds that brought data in support of Burry’s argument:

So, What’s Going On?

We took the passive bubble argument to a logical conclusion: If its real, it has to burst at some point.  So, we asked the #Fintwit world:

Assuming the “passive bubble” is real what would you short to capitalize on the “POP”?


As you can see, investors aren’t clear on how to capitalize on the “passive bubble.” Probably because the fears of a broad-based passive bubble are overstated. We agree with the small majority; short the over-owned sectors that ETFs have identified as bubbles whether or not causality is implied.

Here is what we see:

  1. The transparency of ETFs allows investors to identify and participate in bubbles that are actually caused by herd investing or government intervention.
  2. ETFs are not the cause of broad-based bubbles, but can influence the prices of sub-sectors, factors or fixed income capital structure.
  3. We believe the benefits outweigh the risk. The ETF is a fintech-enhanced version of the mutual fund. The structure has no leverage and complete transparency.
  4. The passive bubble is a ridiculous question that needs to be asked in academia not in fear mongering financial media.
