If investors needed a reminder that global stock market rallies have been goosed by the Fed's lose monetary measures, they got it.
On Wednesday, U.S. equities went on roller-coaster ride.
The Dow Jones Industrial Average, up 155 points before FOMC Chairman Ben Bernanke said the Fed could soon begin to tap the brakes, ended the day down 80.41, or off by 0.5%,.
The uncertainty of when the Fed would begin to wind down its $85 billion-a-month in asset purchases sent investors to the sidelines in a hurry.
"This is a very sensitive market and particularity sensitive to any notion that tapering will come too soon," Quincy Krosby, market strategist at Prudential Financial in New York told Reuters.
"No one wants to be selling if the data reaches the point when the Fed begins to specifically talk about tapering. The market doesn't wait for the Fed to move. It will move before. That's how it operates," Krosby continued.
Of course, we knew QE couldn't really last forever. So what should investors do?..
