Some feel that every time US Federal Reserve Board Chairman Allan Greenspan speaks, the US stock market shudders. He gave testimony before the Senate Banking Committee on February 26, 1997 and the Dow Jones industrial average plunged over 55 points that day (after a rebound from a 122 point loss). You can read the chairman's testimony and his recent speeches at the Federal Reserve Board site (the speeches and testimony of other officials are also available). Read the speeches and testimony, watch the market, and judge for yourself the power of one man in the US economy.
