The hot potato in this market is the Direxion Financial Bull 3X ETF (NYSE:FAS). Last week it logged 1.788-million transactions, while weekly trading volume was 1.6-billion shares. Investors want to be bullish about the financial sector, and are willing to roll the dice - leveraged for winning big. The extreme volatility of this beast goes without saying, but the potential for a big move in FAS must be enticing for quite a few traders. Another 303-million shares traded today as FAS advanced to close at $5.50.
