U.S. stock index futures rose on Thursday, looking to add to gains in the previous session after the Federal Reserve pledged to keep rates low for an extended period and Visa reported strong quarterly results.

The Fed was also more upbeat about the U.S. economy and employment prospects, which helped to boost bank shares.

There's a better feeling out there, and the fact that the Fed continues to stay on a steady course is contributing to enthusiasm, said Peter Cardillo, chief market economist at Avalon Partners in New York.

Dow component Procter & Gamble Co posted a better profit than it anticipated, but the stock slid 1.5 percent to $62.20 in premarket trading.

Both Aetna Inc and Visa Inc reported quarterly earnings that beat expectations, and Visa raised its revenue outlook.

The earnings show that corporate America is quite optimistic, and that's really helping the market, Cardillo said.

S&P 500 futures rose 5.6 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 jumped 43 points, while Nasdaq 100 futures gained 7.5 points.
