NEW YORK, Nov 15 (Reuters) - U.S. stock index futures rose on Friday, buoyed by reassuring remarks by Federal Reserve chair nominee Janet Yellen, setting up the Dow and S&P 500 indexes for fresh record highs.
Wall Street rallied Thursday, with the S&P 500 ending just 10 points away from 1,800, its next level of potential resistance, after a robust defense of monetary stimulus from Yellen, who is expected to succeed Ben Bernanke as chairman of the U.S. Federal Reserve early next year.
New York state's manufacturing sector unexpectedly shrank this month, but business optimism remained relatively resilient, a report from the New York Federal Reserve showed on Friday. The market barely reacted to the data.

No major S&P 500 companies are due to report earnings.
"The post-Yellen rally seems to be continuing but with the S&P 500 within the range of 1,800, the market will be a bit bumpy as we approach that," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.
S&P 500 futures rose 4.3 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures rose 34 points and Nasdaq 100 futures added 9.5 points.
