If there was any doubt that the stock market remained dependent on the Federal Reserve, it was proven twice again. Last week, Chairman Ben Bernanke said the central bank could begin pulling back on stimulus measures, commonly referred to as quantitative easing, if officials see evidence of "sustained" economic growth. Those comments along with a flurry of good economic reports knocked the S&P 500 down by 1.1% as traders worried that the Fed might soon release the market to swim on its own.
