mwvt, sure I’m aware of all that. the quants that blew up were not purists or using anything that F&F would necessarily agree with - that’s why i made the steroids comment. DFA makes a lot of sense, and as i mentioned, most investors aren’t disciplined to stick with these hyper-rational portfolios. thus the edge that DFA takes advantage of never really goes away. If mechanical, or formulaic investing is your thing then DFA is a very solid choice imho.
here’s the article i was thinking of which, upon review, wanders around a bit more than i remembered. not even sure that the author has the F&F theory right.

“Academics, notably Eugene Fama at the University of Chicago with Kenneth French at Dartmouth, have documented how, over time, stocks with smaller market capitalizations and lower valuations tend to do better than the overall stock market.
The reason for the outperformance, Mr. Pradhuman said, is both smaller companies and companies with low valuations are more likely to go bust if the economy sours, so they are riskier. Since the U.S. economy has been highly successful, taking the risk of buying the shares of such companies has paid off.
Since history had shown that buying small and low multiple companies was a good idea, many quant models screened for them. When stocks started getting rattled last month after credit markets seized up, worries about business risk rose sharply and the shares of those companies bore the brunt of the selling.
Other investors had bid up the share prices of some of these companies in the belief that leveraged-buyout firms would snap them up at healthy premiums. When credit tightened, takeover prospects dimmed. The combined effect of some quant funds and other investors cutting positions in the stocks sent them lower still.” - WSJ [Continues]

“University of Rochester finance professor William Schwert has found that after academic papers come out highlighting opportunities to outperform the market, those opportunities tend to diminish or outright disappear. The popularity of quantitative strategies in recent years may mean that the opportunities to make money are getting whittled away more quickly than ever, according to Invesco PLC investment strategist Diane Garnick.” - WSJ [Continues]
