Broader stock indicators, which were again taking a much bigger bruising than the Dow 30, ended lower. Technology, Internet and financial stocks suffered some of the biggest losses.

Analysts attributed the selling frenzy to this week's sudden nose dive by the dollar in currency trading. The dollar fell sharply again Thursday after sliding 8.1 percent on Wednesday against the Japanese yen, the biggest one-day drop in a quarter century.
Hedge funds, secretive ventures that invest for wealthy clients, were said to be unloading some of their riskier bets on the dollar, weighing down dollar-denominated investments including stocks and Treasury bonds. With the dollar dropping, there also is less incentive for foreigners to invest in U.S. stocks and bonds.

Hedge fund short-covering of bets against the yen and Japanese bank repatriation of capital have also pressured the dollar.The technology-heavy Nasdaq composite index was down 48.93 at 1,413.67.
