NEW YORK, Nov 11 (Reuters) - The Dow and the Standard & Poor's 500 index closed at 13-month highs on Wednesday as an upbeat forecast from a top homebuilder and data from China pointed to a strengthening global economy.

The Dow's advance was its sixth straight as comments from top Federal Reserve officials suggesting low interest rates will stay for some time added to the positive tone.

Luxury homebuilder Toll Brothers Inc (TOL.N) late Tuesday forecast revenue that was sharply higher than expected, lifting the Dow Jones homebuilders index .DJUSHB 7.1 percent. Toll jumped 16.4 percent to $21.41.

Data before the open showed Chinese factory output rose to a 19-month high in October. Investors bet the data heralded growing demand in the world's third-largest economy. For details, see [ID:nPEK212006].

"There was fairly bullish news coming from China with respect to its industrial production, which has exerted upward pressure on commodities and commodity-related stocks," said Matt Kaufler, portfolio manager and equity analyst at Clover Capital Management in Rochester, New York.

After the closing bell, shares of network equipment maker 3Com Corp (COMS.O) rose 34 percent to $7.64 after Hewlett-Packard Co (HPQ.N) said it agreed to buy 3Com for $2.7 billion. [ID:nN11380741].

The Dow Jones industrial average .DJI was up 44.29 points, or 0.43 percent, at 10,291.26. The Standard & Poor's 500 Index .SPX was up 5.50 points, or 0.50 percent, at 1,098.51. The Nasdaq Composite Index .IXIC was up 15.82 points, or 0.74 percent, at 2,166.90.

The Hewlett-Packard announcement could give investors reason to extend the stock market's gains.

The technology sector is "where the concentration of deal flow is, and it seems to me that might be supportive of the market at this juncture," Rob Stein, managing partner of Astor Asset Management in Chicago, said.
