Predicting market direction: It's a lonely sport!

Just for the record, I bought more shares of TZA today at $31.30/share taking advantage of the move up today in the market. I was rewarded for this purchase so far, as the ETF, Ultra Short Triple play, TZA, closed at $33.65/share. The Dow closed at 7,887. The Put to Call closed at 0.78 and the VIX Index closed at 38.10, while Gold closed up today to $893/ounce. Where is the market headed? Why am I buying Shorts?
