Stock index futures were little changed on Wednesday as investors weighed comments from the Federal Reserve on the economy and banking sector against the recent five-day rally.

The Fed said most of the largest U.S. banks passed their annual stress test in a report that underscored the recovery of the financial sector but called out a few laggards, including Citigroup Inc.

The Fed also said late Tuesday it expects moderate growth over coming quarters with the unemployment rate declining gradually versus the modest growth the central bank said it expected in January.

Banks have been a leading component of the 11 percent rally in the S&P for the year, with the KBW Bank index <.BKX> up more than 20 percent and the S&P financial sector index <.GSPF> up more than 18 percent.

The stress tests kind of marked the unofficial end of the 2008 financial crisis, said Rick Meckler, president of investment firm LibertyView Capital Management in New York.

There is a lot of news in the market in the last couple of days of a global nature, Meckler said, referring to the Greek debt crisis and the Fed's policy statement. Given the fact the market has rallied so far, you have investors coming in today and trying to consider what the next phase for the market will be.

Bank of America Corp climbed 2.6 percent to $8.71 in premarket trade. Citigroup Inc dropped 4.2 percent to $34.93.

The increasing optimism on the U.S. economy helped boost the dollar, which hit an 11-month high against the yen and 1-month high versus the euro.
