A multibillion-dollar acquisition by Citigroup and strong sales at Wal-Mart gave those stocks a boost, but failed to energize the markets. Federal Reserve Chairman Alan Greenspan’s remarks to a credit union conference that American consumers are in "good shape" following a wave of mortgage refinancings also had little positive effect.

The fourth straight day of declines reflects lingering concerns over valuations and rising questions about whether the economic recovery will hold, said Stephen Massocca, president of Pacific Growth Equities.

There are also growing worries on Wall Street about the upcoming presidential election, he said.

"Nothing in the headlines today was able to allay those concerns," Massocca said. "We’ve also not seen a significant correction since March, and a lot of people are concerned that we’re due for one, and they’re pulling back while they can."

According to preliminary calculations, the Nasdaq shed 30.41, or 1.5 percent, to 2,007.52, after falling 0.8 percent last week. The tech-heavy index was up just 0.2 percent for the year, having closed 2003 at 2003.37.

The other major indexes were narrowly lower. The Dow Jones industrial average gave up 9.41, or 0.1 percent, to finish at 10,609.62, after a weekly decline of 0.1 percent. The Standard & Poor’s 500 index lost 3.12, or 0.3 percent, to 1,140.99, following a 0.2 percent drop.

The Nasdaq’s weakness is "obviously part of a larger picture of market correction," said Richard E. Cripps, chief market strategist for Legg Mason of Baltimore. But the economy’s underlying strength and the prospect of continued corporate earnings growth are likely to mitigate the long-term impact, he said.

"It’s a consequence of how far, how fast and how widespread the gains have been for the last 10 weeks," Cripps said. "I’d say we’re going through a sentimental correction, not one precipitated by fundamentals."

Intel Corp. dropped $1.00 to $29.00 after the chipmaker reported in federal filings that the Internal Revenue Service was examining its tax returns for 2001 and 2002.
