Gold started selling off the previous week after the Fed planted a QE story at the Wall Street Journal on Wednesday. With only a limited bounce thereafter the selling has been consistent. Why? Hot money is leaving gold markets and moving to stocks. It doesn't help gold that the dollar is also rising returning both to their normal inverse relationship.
The dollar hasn't rallied dramatically but enough to chase gold bulls. Momentum for U.S. stocks is strong even with a smaller than usual number of players as volume remains historically light.
