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.
