Even after recent turbulence, the Dow Jones Industrial Average is up roughly 30% since its low in March. It is natural for you to feel happy or relieved about that. But Benjamin Graham believed, instead, that you should train yourself to feel worried about such events.
At this moment, consulting Mr. Graham's wisdom is especially fitting. Sixty years ago, on May 25, 1949, the founder of financial analysis published his book, "The Intelligent Investor," in whose honor this column is named. And today the market seems to be in just the kind of mood that would have worried Mr. Graham: a jittery optimism, an insecure and almost desperate need to believe that the worst is over. ...
Stocks have suddenly become more expensive to accumulate. Since March, according to data from Robert Shiller of Yale, the price/earnings ratio of the S&P 500 index has jumped from 13.1 to 15.5. That's the sharpest, fastest rise in almost a quarter-century. (As Graham suggested, Prof. Shiller uses a 10-year average P/E ratio, adjusted for inflation.)
Over the course of 10 weeks, stocks have moved from the edge of the bargain bin to the full-price rack. So, unless you are retired and living off your investments, you shouldn't be celebrating, you should be worrying.
