NEW YORK — U.S. stock futures are mixed in light trading with investors holding back before the Federal Reserve reveals its stance on the economy.

Markets have swung wildly for weeks leading up to the two-day meeting, which ends Wednesday.

Dow Jones industrial futures are down 14 points to 15,230. The broader S&P futures have fallen less than a point to 1,644.40. Nasdaq futures are up 2.75 points to 2,991.25.

Economic indicators are painting an image of an economy on the mend, though still fragile.

It's been uncertainty about how the Fed reads those signals, and whether it will maintain its aggressive economic stimulus efforts.

If the answer is no, the question then becomes how fast it will dismantle a massive bond-buying program that has kept markets flush with cash, and interest rates low.
