NEW YORK -- Investors plowed money into stocks and bonds after the Federal Reserve's surprise decision to keep its economic stimulus program in place.
The news sent the Standard & Poor's 500 index and the Dow Jones industrial average to record highs.
Bond yields fell sharply after the central bank said it would continue its huge bond-buying program.
Gold prices also rose and the dollar fell as investors anticipated that the continuation of the program might lead to inflation.
The S&P 500 was up 16 points, or 1 percent, to 1,721 in afternoon trading. The Dow rose 114 points, or 0.7 percent, to 15,641.
The yield on the 10-year Treasury note fell to 2.76 percent from 2.87 percent.
