U.S. stock index futures edged lower on Tuesday after data on retail sales and New York State manufacturing.

January retail sales rose less than expected, while the February reading on New York manufacturing came in above forecasts.

S&P 500 futures fell 1.9 points and were below 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 dropped 6 points, and Nasdaq 100 futures were off 1.75 points.
