Here’s a puzzle: The stock markets are doing very well, yet the performance of the underlying economy doesn’t seem to justify optimism. The buoyant S&P 500 has risen 53 percent since the March bottom. And while the economy expanded at a 3.5 percent rate in the third quarter, unemployment is high, incomes are stagnant, and consumers are shaky.
It’s possible that the stock market is just getting it wrong again. After all, the markets, which are supposed to process investors’ attitudes about the future, hit record highs in October 2007, just as the U.S. economy was about to pitch into recession. But it could be that the notion the stock market is an accurate gauge of the domestic economy’s temperature is outdated.
