The Dow dropped 1300 points in a couple of days and the CNBC fear machine cranked into high gear. Even Fox Business News got into the action with the headline grabber “Biggest market crash in our lifetime coming – economist Harry Dent.” Of course if you google “Harry Dent crash,” he makes the same call every year so it is meaningless. The real question is: should you buy or sell the fear? The answer: it depends.
