NEW YORK, Sept 15 (Reuters) - U.S. stocks were falling on Monday, dragged down by the tech sector as investors make space in their portfolios for Alibaba's planned debut later this week and biotech shares weighed further on the Nasdaq.
Alibaba's could be the largest initial public offer in history and has seen "overwhelming" interest, meaning Yahoo's 23 percent stake could be worth more next week than it is now. Yahoo stock was up 1.7 percent with 1.9 million shares already traded.
"The Alibaba IPO is going to have a big effect, drawing money out of some stocks, and how it performs can help say a lot about the tech sector," said Rick Meckler, president of LibertyView Capital Management in Jersey City, New Jersey.
Among the most active stocks on the Nasdaq were Yahoo Inc , holder of a 23 percent stake in Alibaba, up 0.7 percent to $43.18; Avanir Pharma, up 54.2 percent to $10.39; and Apple Inc, up 0.3 percent to $101.96.
On the NYSE, Bank of America, up 0.24 percent to $16.83; Nokia Corp up 2.39 percent to $8.57; and Sprint Corp, down 1.43 percent to $6.90, were among the most actively traded.
The Dow Jones industrial average was falling 32.02 points, or 0.19 percent, at 16,955.49, the S&P 500 was losing 6.52 points, or 0.33 percent, at 1,979.02 and the Nasdaq Composite was dropping 39.60 points, or 0.87 percent, at 4,528.00. Continuación...
