Stocks up, dollar down, commodities up. And although Gold is also influenced by inflation fears etc it is still a commodity.

So if stocks drop, dollar will rise and gold will drop. Unless stocks drop because of some serious fears, then gold might become a safehaven again.

A year ago gold outperformed because there where inflation-fears. Right now these are temporarily gone, so Gold is traded as all other commodities and thus directly correlated to the price of the dollar, which in turn is correlated to the stock market.
