Stock index futures bounced back on Wednesday after five days of losses on the S&P 500 that brought the benchmark index down more than 4 percent.

Tuesday marked the largest daily percentage decline on the S&P in four months, and investors will evaluate if the slide presents an opportunity for those who missed the market gains in the first three months of the year.

After a 12 percent gain on the S&P in the first quarter, this recent pullback should provide an entry opportunity for those underweight in stocks, said Andre Bakhos, director of market analytics at Lek Securities in New York.

Sectors associated with economic growth were among the hardest hit Tuesday, making them attractive to bargain hunters. The Select Sector Financial SPDR ETF gained 1.2 percent premarket with Bank of America up 2.3 percent at $8.74.

Earnings season started on a high note Tuesday a day after aluminum producer and Dow component Alcoa Inc surprised Wall Street with a first-quarter profit, following a loss in last year's fourth quarter. Alcoa shares rose 5.8 percent to $9.86 in premarket trading.

S&P 500 futures rose 10.9 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 86 points, and Nasdaq 100 futures added 18.75 points.
