Does this means pillar 2 above does not actually hold, the market can become unbalanced and passive investing can become "crowded" ?
Almost every form of investment strategy has the potential to become crowded. See overvalued markets/single names (if valuation was a constraint then markets/single names would never become overvalued). Also google the term "hedge fund hotel" or "quant meltdown 2007".
However worth noting again that most strategies are less crowded than commonly assumed, especially assumptions from the counterparty who believes the opposite strategy is foolish and crowded. Fundamental investors think momentum is crowded because anyone can implement. Momentum investors think fundies do nothing but catch all the falling knives. Active investors think passive is so crowded. And so on...
Given the ever increasing inflows into passive investing and the death of active management
I disagree that active management is dying (Pershing has an AUM of what? 18 billion? Just 1 fund. Berkshire is running >300 billion market cap...), and plenty of money "outflows" from passive investing every time there is a 5, 10, 20, 50% drawdown in passive indices as investors sell at inopportune moments.
Also Sinner, any other recommendations for other papers illustrating similar "truths" in the market ? Would love to get ahold of your reading list.
I like this http://www.hussmanfunds.com/wmc/wmc140414.htm but others seem to disagree/less enthusiastic. The only contention I have is that it assumes "constant dollars", i.e. no major change in real value of the unit of account.
My list is long, I have pasted plenty of links, feel free to go through my posts.
