NEW YORK (TheStreet) -- U.S. stocks jumped on dovish comments from Federal Reserve Chair Janet Yellen. Trading is expected to be more volatile as investors close their first-quarter positions, a time when fund managers often sell their worst-performing stocks and buy the best-performing stocks to improve the appearance of portfolio statements. Global equity markets rose as Chinese and European Central Bank stimulus hopes persisted.
Yellen described the U.S. economy and labor market as far from healthy, suggesting the Fed's low interest rate policy will persist for some time. She told a conference the U.S. economy was "still considerably short" of the two goals assigned to the central bank: supporting low, stable inflation and maximum sustainable employment.
