The Federal Reserve is widely expected to raise interest rate later this year, perhaps as early as June. The Fed tried to jumpstart the economy during the Great Recession by cutting rates down near zero in December 2008. It hasn't touched rates since.
The stimulus fueled a stock market surge. The S&P 500 has risen about 200% since bottoming out in March 2009. A rising tide lifted all boats. But that rising tide -- the Fed's stimulus -- will soon fade.
