NEW YORK — The stock market greeted news of U.S. military attacks on the Taliban in Afghanistan quietly Monday, with prices falling moderately as investors tried to discern what the action would mean for the country and the economy.

While tech shares eked out a tiny gain, investors mostly locked in profits from last week's rally.

The market was worried that the United States will suffer more terrorism as American and British forces conducted a second day of missile attacks in Afghanistan, retaliating for the Sept. 11 terrorist assaults in New York and Washington. Investors are also concerned about how long and how much the weakened economy will suffer following the attacks.

The Dow Jones industrial average closed down 51.83 at 9,067.94, having risen 272.21, or 3.1 percent, last week.

The broader market finished mixed. The Nasdaq composite index inched up 0.65 to 1,605.95 to just barely claim its first five-session winning streak since the week of June 25. Last week, the tech-focused index rose 106.50, or 7.1 percent.

The Standard & Poor's 500 index, Wall Street's widest measure, fell 8.94 to 1,062.44.

Monday's mild pullback was expected given the political uncertainty and last week's rally, which was spurred by the Federal Reserve's ninth interest rate cut of the year and a push by President Bush for an economic stimulus package worth $60 billion.

``The market is attempting to stabilize,'' said Alan Ackerman, executive vice president of Fahnestock & Co.

Analysts were encouraged by the Nasdaq's narrow gain and that blue chip selling wasn't greater.

``Markets have historically recovered from catastrophes with a decent relief rally. It appears we are in one of those right now,'' Ackerman said.

Still, Monday's session was fairly lackluster as the market flipped between minor gains and losses. Trading volume was lighter than normal, which could be attributed partly to traders' caution, as well as the Columbus Day federal holiday. There also were no major third-quarter earnings reports due to be released.

``This is a combination of things. There is some concern on the part of some investors about the retaliation. There is also some ordinary profit taking from the extraordinary strong run,'' said Bill Barker, investment strategy consultant for Dain Rauscher in Dallas, who also noted the holiday.

``Actually, the market is holding better than you might expect given those things,'' Barker said.

Losses centered on companies whose business prospects remain poor. The nation's three big automakers fell on a report in the Financial Times that Ford Motor, General Motors and DaimlerChrysler are slashing production by a further 196,000 vehicles before the end of the year. Ford fell 38 cents to $17.29, General Motors lost 71 cents to close at $41.65, and DaimlerChrysler slipped 25 cents to $33.87.

But stocks fell across sectors, indicating investors' unwillingness to bet on the success of any business. Banker J.P. Morgan Chase fell 97 cents to $32.44, while Wal-Mart declined $1.29 to $51.11. Fast-food chain Wendy's stumbled 66 cents to $26.54 after issuing a third-quarter profit warning.
