NEW YORK, Jan 9 (Reuters) - U.S. stock index futures rose modestly on Wednesday as Alcoa got the earnings season underway with better-than-expected revenue.
* Alcoa Inc also gave a positive outlook for 2013, but kept a cautious tone as worries lingered over a looming U.S. budget confrontation. Shares of Alcoa, the largest aluminum producer in the United States, rose 1.9 percent to $9.27 in premarket trade.
* Even with the encouraging Alcoa report, investors were wary about the outcome of the fourth-quarter earnings season.

* Equities have pulled back over the last two sessions after last week's rally, which was spurred by the "fiscal cliff" deal in Washington.
* S&P 500 futures rose 0.2 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 added 11 points, and Nasdaq 100 futures gained 0.25 points.
* Dish Network Corp late Tuesday announced a bid for Clearwire Corp that trumped Sprint Nextel Corp's $2.2 billion offer, setting the stage for a battle over the wireless service provider. Clearwire was up 9.6 percent at $3.20 in premarket trading.
