Almost never mentioned is that Graham (of Graham & Dodds) almost went bankrupt while applying the methodology. Arguably, untill the recovery actually began, he survived only because he had more money than he had places to put it. Downside volatility.
Graham made his money, primarily because he was overweight the right stocks at the start of the recovery, & then held them pretty much through to the top of the cycle. The methodology got him there, but its not universal - it works only in up-cycles. Were today's hedging instruments available at the time, he might well have actually made more in the down-cycles.
Almost all value investors have been experiencing extreme adverse downside volatility, & in most cases they made thier money in the up-cycles - classic Graham. A very few have modernized the methodology, largely by taking the opposit side of market hedges (ie: FFH-CDS's, WEB-S&P option puts).
We may well eventually conclude that WEB & coy actually had too much capital, & that it effectively drove them into the market too early. They did not risk bankruptcy because they were able to efficiently hedge, something that Graham wasn't able to do.
Its not always a bargain
