NEW YORK, Oct 22 (Reuters) - U.S. stocks edged higher on Wednesday, with the S&P 500 up for a fifth straight day as technology companies rallied on strong results, though weakness in Boeing weighed on the Dow.
With the session's advance, which builds on a jump of about 2 percent on Tuesday, the S&P 500 is up 4.5 percent over the past five sessions, putting it on track for the biggest five-day rally since December 2011.
Tech names were among the market's biggest advancers a day after both Yahoo Inc and Broadcom beat revenue expectations. Broadcom shares climbed 7.2 percent to $40.01 while Yahoo was up 5.7 percent at $42.47; the two made up the S&P 500's top percentage gainers.
Material stocks also outperformed on the day, up 0.6 percent, after Dow Chemical posted better-than-expected earnings. The stock rose 1.2 percent to $48.78. Continuación...
