Oct 28 (Reuters) - U.S. stocks were higher on Wednesday, boosted by gains in Apple and a sharp bounce in energy stocks, ahead of the Federal Reserve's statement on interest rates.
The Fed's statement is due at 2:00 p.m. ET (1800 GMT), after its two-day policy meeting ends. The central bank hasn't hiked rates in about a decade and markets see virtually no chance it will do so at the meeting.
However, traders will scrutinize the statement for clues on when the Fed will pull the trigger.
The market is likely to remain calm until after the Fed's announcement, said Jeff Powell, managing partner of Polaris Wealth Advisors.
If the Fed uses language that implies 'immediate' or 'impending', people might interpret that as a cue for a move in December, Powell said.
The odds for a rate hike in December are now at 38 percent, according to the CME Group's FedWatch program.
At 12:55 a.m. ET, the Dow Jones industrial average was up 93.1 points, or 0.53 percent, at 17,674.53, the S&P 500 was up 13.4 points, or 0.65 percent, at 2,079.29 and the Nasdaq composite index was up 33.98 points, or 0.68 percent, at 5,064.13.

AIG jumped 3.7 percent to $63.19 after activist investor Carl Icahn disclosed a "large stake" in the insurer and said the company should split itself into three listed entities.

Amgen, GoPro and PayPal will post results after the close.
