A look at highlights from the day's business news:
Stocks advanced Wednesday afternoon, with the Dow, Nasdaq and S&P 500 all touching fresh 2010 highs after the U.S. and Japanese central banks chose to keep interest rates low and the Senate passed a key jobs bill.
The Dow Jones industrial average added 44 points, or 0.4 percent, rising as high as 10,767.98 and surpassing the 2010 closing high of 10,725.43 hit on Jan. 19. Should the Dow close above that level, it would be at an almost 18-month peak.
The S&P 500 index rose 6 points, or 0.5 percent, and was on track to close at its highest point since Sept. 26, 2008. The Nasdaq composite gained 10 points, or 0.5 percent, and was on track to close at its highest point since Aug. 28, 2008.
Stocks were moderately higher in the morning, but picked up the pace in the afternoon after the Senate passed a key jobs bill and the dollar's weakness sparked a rally in commodity prices and stocks.

What's moving the market: Stocks gained after investors let the Fed's news - or rather, lack of news - soak in. Although the Fed decided to maintain historically low interest rates, the central bank also noted that the U.S. economy is improving.
