Dow dives 158 on bad day for Wall Street

Wall Street had its worst day in more than four months today as the dollar weakened and concerns about the strength of the retail industry arose following a rare sales decline at Wal-Mart. The Dow Jones industrials fell 158 points.

Us investors were uneasy after the dollar fell for the fifth day in a row and after Wal-Mart, the world’s largest retailer, reported a 0.1% drop in same-store sales, those from stores open at least a year.
