NEW YORK, Oct 9 (Reuters) - U.S. stocks rose in skittish trade on Thursday as investors snapped up beaten down shares after a six-day slide and a solid profit from IBM <IBM.N> spurred hope that the credit crisis might not be stifling all demand.
Shares of International Business Machines Corp, a technology services giant, rose 2 percent, making the stock a top boost to the Dow, while Apple Inc <AAPL.O> , another tech bellwether, led the Nasdaq with a 4 percent gain.
But trading was skittish, with some market participants away for the Jewish Yom Kippur holiday.
The hunt for cut-price shares also fueled a recovery in the shares of natural resource companies, with aluminum producer Alcoa <AA.N> , rebounding nearly 6 percent after the stock was hammered in the wake of a profit shortfall that the company posted on Tuesday.
"What we're seeing is just a bear market rally. An oversold rally," said Dave Rovelli, managing director U.S. equity trading at Canaccord Adams in New York. "You could see a significant rally over the next couple of days. The market is so oversold."
The Dow Jones industrial average <
> added 48.91 points, or 0.53 percent, to 9,307.01. The Standard & Poor's 500 Index <.SPX> climbed 4.08 points, or 0.41 percent, to 989.02. The Nasdaq Composite Index < > shot up 17.03 points, or 0.98 percent, to 1,757.36.IBM shares rose to $92.45 on the New York Stock Exchange, while Apple climbed to $92.83 on Nasdaq.
Even so, lowered profit estimates by some major retailers, including TJX Cos Inc <TJX.N>, fueled some caution about the outlook for consumer spending. TJX shares fell 3.7 percent to $26.61 after the off-price retailer cut its profit outlook.
The expiration of a U.S. Securities and Exchange Commission's ban on short selling in more than 950 financial stocks cast a pall on individual financial stocks, including Morgan Stanley <MS.N> , whose shares slid 11 percent to $14.88 on the NYSE.
Short sellers borrow shares and sell them in anticipation that the price will fall. They then buy the shares back at the lower price, returning them to the broker, and profiting on the price decline.
On the economic front, a government report showed the number of U.S. workers filing new claims for jobless benefits fell 20,000 last week, in line with forecasts as the impact of hurricanes Gustav and Ike eased. For details, see [
