On Tuesday, the stock markets put in another dismal performance, with all major indices closing down on the day. The Dow Jones Industrial Average closed at 6726, down 37 points, about 20 points above its low and 125 points below its mid-day high. And immediately after the bell, futures are trading substantially lower, as if the Dow were down another 25 points or so. The market closed at levels last seen in October, 1996. Technology stocks were slightly stronger, with the Nasdaq down only two points, but also much closer to its daily low than high.
