NEW YORK (AP) — U.S. stock futures are rising, but only after swinging wildly following the worst day for stocks since 2008.

About two hours ahead of the opening bell, Dow Jones industrial futures are up 172 points, or 1.6 percent, at 10,898. They were down more than 200 points earlier in the morning, but swung higher to be up more than 300 points.

S&P 500 futures are up 20, or 1.8 percent, to 1,131. Nasdaq 100 futures are up 37, or 1.8 percent, to 2,075.

Futures do not always accurately predict how stocks will trade once the market opens.

The Dow plunged 634.76 points on Monday in the first trading since Standard & Poor's downgraded the U.S. credit rating. Worries are rising that both the U.S. economy and Europe's debt problems are worsening.
