New York ? Wall Street shot higher Monday on better-than-expected manufacturing data, but gave up much of its gains after the Dow Jones industrials surpassed the 9,000 mark for the first time since December.

Analysts said investors were upbeat about an economic recovery, but some were cashing in profits on concerns that the market’s recent surge might have come too far, too soon.

“The economic activity is slow to improve but the market is optimistic,” said John C. Forelli, portfolio manager for Independence Investment LLC in Boston. “For the market, the glass is half-full — as opposed to three-quarters empty as it had been for a while.”

The Dow closed up 47.55, or 0.5 percent, at 8,897.81, following a weekly advance of 2.9 percent last week. It was the best level seen since Nov. 27, 2002, when the Dow closed at 8,931.68.

Earlier in the afternoon, the blue chips rose as much as 153 points to hit 9,003.27. The last time the Dow rose above 9,000 during the day was Dec. 2, 2002; the last time the blue chips closed above 9,000 was Aug. 22, 2002, when they stood at 9,053.64.

The broader market finished mixed. The Nasdaq composite index fell 5.16, or 0.3 percent, to 1,590.75, after gaining 5.7 percent last week. Earlier in the day, the tech-focused index rose as much as 24 points.

The Standard & Poor’s 500 index rose 3.41, or 0.4 percent, to 967.00, having risen 3.3 percent last week. The index closed above its Sept. 21, 2001, low of 965.80 for the first time since July 8, 2002.

The Institute for Supply Management reported that its manufacturing index was 49.4 percent last month, up from 45.4 in April. A reading below 50 means manufacturing activity is slowing; still, the figure was better than the 48.5 that economists were expecting.

However, the Commerce Department said spending on construction projects dipped by 0.3 percent in April from March to a seasonally adjusted annual rate of $862.6 billion. It was the third straight month that spending fell and was weaker than the 0.2 increase analysts were expecting.

Stocks have surged in recent weeks on a wave of better-than-expected earnings and positive economic data. Analysts say investors are more confident about an economic rebound by year’s end, although the market is still vulnerable to sharp declines on profit-taking.

“There’s an undercurrent of improving economic activity,” said A.C. Moore, chief investment strategist for Dunvegan Associates. “It’s hard to see on a month-to-month basis, but if you squint your eyes you can see it. Consumer confidence is returning … that spells for a better market performance as we look at a very low interest rate.”

Forelli agreed, but added that it would be hard for Wall Street to maintain its upward momentum after several weeks of strong gains.
