Gold Prices Are Sliding

As stock markets rally, metals are selling off.

Gold is down 1.3 percent, silver is off 1.4 percent, platinum is down 1.3 percent, and copper is down 0.5 percent. Palladium is however up 0.40 percent.

Gold had its "biggest one day rally in three months" yesterday, according to Reuters, after Fed chairman Ben Bernanke said the Fed was committed to easy monetary policy during his testimony.
