NEW YORK, Aug 6 (Reuters) - U.S. technology shares rose on Wednesday, boosting optimism about future corporate spending and profits, but the Dow and S&P were little changed due to concerns about fallout from the mortgage crisis.
Tech stocks rose after Cisco Systems Inc <CSCO.O>, the largest U.S. maker of equipment that directs Web traffic, said it expects the weak economic environment to be relatively short-lived. Shares jumped 6 percent, making the stock the biggest percentage gainer on the Nasdaq 100 index and a leader on the S&P 500.
The technology sector also got a lift from a report Microsoft Corp <MSFT.O> may buy back as much as $20 billion of its stock to boost its share price. Shares rose nearly 2 percent after the report by Bloomberg News, citing a UBS analyst report. Microsoft could not be reached for comment.
Further declines in oil's price helped the broad market recover from earlier losses sparked by a news of a fourth straight quarterly loss from home finance company Freddie Mac <FRE.N>, which was down 12 percent.
"People were encouraged by what Cisco had to say. There's a different mind-set, even though the Freddie Mac news was pretty bleak," said Dave Rovelli, managing director of U.S. equity trading at Canaccord Adams in New York.
"All big-cap tech is seeing strength. What is also bullish today is the talk that Microsoft might be buying back $20 billion worth of stock. That's a very good sign."
The Dow Jones industrial average <
> was down 12.05 points, or 0.10 percent, at 11,603.72. The Standard & Poor's 500 Index <.SPX> was down 2.41 points, or 0.19 percent, at 1,282.47. The Nasdaq Composite Index < > was up 10.73 points, or 0.46 percent, at 2,360.56.Shares of Cisco rose 5.8 percent to $23.96, while shares of Microsoft rose 1.8 percent to $26.69. For details, see [
]Investors also grew hopeful about future consumer and business spending after oil <CLc1> touched a three-month low below $118 a barrel before paring losses to trade at $119.10 -- still far below a record high above $147 in July.
On the Dow, shares of Caterpillar Inc <CAT.N> rose 2 percent to $69.51, boosted by lower oil prices. Aluminum company Alcoa Inc <AA.N> shares rose 1.4 percent to $32.10.
Earlier, Freddie Mac's wider-than-expected loss pushed stock prices lower and stoked concern about financial shares and the ongoing U.S. housing slump.
Freddie Mac said it was setting aside twice as much money for bad loans and made plans to slash its dividend by at least 80 percent. [

Lancz & Associates Inc, an investment advisory firm in Toledo, Ohio. "I still think there will be more problems, not only with Fannie and Freddie, but also with a number of banks," he said.
