S&P 500 and Nasdaq 100 stock index futures fell on Tuesday following results from top global chipmaker Intel Corp that beat expectations, but only gave an informal revenue outlook for the current quarter.

Shares of Intel fell 4.4 percent to $15.30 in extended trading.

S&P 500 futures fell 3.80 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 climbed 10 points, while Nasdaq 100 futures lost 17.25 points.
