Predicting What You Already Knew

A comment supporting Nate Silver's critique of an Economist's recent work:

The market wasn't able to predict the current recession, at least not in any useful way, so why trust it to predict when the economy will emerge?

The current state of the stock market is only one of many factors to be weighed when assessing the health of an economy. An important factor perhaps, but not the only one. Perhaps not even the primary one.
