Value investing - still appropriate?

Ben Steverman in Businessweek asks whether value investing is still the way to go.

Disciples of the value strategy, like Berkshire Hathaway's (BRKA) Warren Buffett, focus on the long-term intrinsic value of a company, hoping to buy shares in good companies at reasonable prices. By focusing on value, they avoid fast-growing firms with expensive stocks, and, by thinking long term, they try not to worry about the fickle gyrations of the market from month to month or day to day.

But amid a severe recession and financial crisis, true value has proven to be a slippery concept. "It's only a value if you can accurately assess today what the future profits will be," says Richard Sparks of Schaeffer's Investment Research. Particularly for financial stocks—some of which haven't or won't survive the crisis—it's nearly impossible to identify the long-term value, whether through profits, cash flow, or other measures.
