NEW YORK, Jan 13 (Reuters) - U.S. stock index futures climbed on Tuesday after the S&P 500 fell for a second consecutive session, as financial results from Alcoa helped ease some investor skittishness about the corporate earnings season.
* Alcoa Inc gained 1.1 percent to $16.35 before the opening bell. The company reported a higher-than-expected quarterly profit due to a boost from automotive demand, higher aluminum prices and lower energy costs.
* Another sharp decline in energy shares as oil prices tumbled about 5 percent and growing concern over corporate profits sent equities lower for a second straight day. The benchmark S&P index has fallen in seven of the past nine sessions and is down 3 percent from its most recent record high on Dec. 29.
