NEW YORK — Wall Street ended a relatively calm session with a moderate loss Tuesday as investors, while happy with the government's plans to spend up to $250 billion to buy stock in private banks, decided to cash in profits from the previous day's massive advance as they refocused their attention on the economy.

It was the first time in nine sessions the Dow Jones industrial average didn't close with triple-digit losses or gains, although it did swing in a 700-point range. The Dow closed down 76 points a day after its record 936-point jump.

Big advances by many bank stocks helped offset some of the declines in the Dow and the Standard & Poor's 500 index, giving them a better showing for the day than the Nasdaq composite index, which fell more than 3 percent. The technology-dominated Nasdaq also lagged ahead of a profit report from Intel, as investors were reminded of the troubled economy and its impact on corporate earnings.

Profit-taking set in after the Dow surged more than 400 points at the opening. Wall Street is expected to see jittery trading in the weeks and perhaps months ahead because of worries about the economy; stocks also tend to ratchet up and down when they're recovering from a plunge like the one Wall Street has suffered in the past two weeks.

"We don't know if the bottom is in," said Lincoln Anderson, chief investment officer and chief economist at LPL Financial, referring to the market's advance Monday after huge losses last week. "We certainly expect heightened volatility for a fair amount of time while we sort out just exactly what's going on."

Investors had snapped up stocks Monday in anticipation of the government's plan. President Bush said Tuesday the government would use a portion of the $700 billion financial bailout passed at the start of the month to inject capital into the nation's major banks, which have been slammed by souring mortgage investments.
