The sixth edition of Security Analysis is a strange amalgamation of Graham’s original work (styled in British English) and new commentary from prominent value-oriented investors (in American English). I find it impossible to read fluidly. Nonetheless the contributors make a strong independent showing, especially Seth Klarman and his protégé, David Abrams. They argue—as I have done in numerous essays—that market inefficiencies are smaller in magnitude and frequency than before.
I am especially pleased that both men acknowledge the hedging opportunities present in derivative securities. This has become my favorite area of study and action—and one that appears unlikely to be outmoded soon. (Elsewhere, I have found much of the “value investing” philosophy to be comparatively inadequate.)
