Most of us hate uncertainty. And it’s our dislike of uncertainty that keeps the weather man and economic forecasters employed. But when was the last time you checked your favorite forecaster’s track record before acting on his or her prognostication? Chances are . . . never. Why bother, right? The weather forecaster gets close enough most of the time – so the economics guys on CNBC and in the newspaper are pretty close most of the time, right? They’re paid to be investment forecasters, after all. Wrong. And that belief could be costing you money.
