The Dow Jones industrial average closed under 10,000 today, for the first time since February.
Stocks were actually up most of the day, sailing on optimistic U.S. economic reports. But in the last hour of trading, the euro slid down, amid news that China may consider reducing its investment in European government bonds. The Dow lost 69 points to close at 9,974.
Investors have been looking at the euro as a measure of the European debt crisis, and the market has been swinging as the currency rises and falls. The Dow has fallen about 11 percent in the last month.
