NEW YORK, Oct 22 (Reuters) - U.S. stocks rose 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 Tuesday's jump of about 2 percent, 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.
The day's gains were broad, with eight on the S&P's ten primary sectors rising. Tech names were among the biggest advancers a day after both Yahoo Inc and Broadcom beat revenue expectations.
Broadcom shares climbed 6.9 percent to $39.90 while Yahoo was up 5.3 percent at $42.34; 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 0.8 percent to $48.58. Continuación...
