FOL Description
FactorShares 2X: Oil Bull/S&P500 Bear (FOL) is a leveraged spread ETF designed for investors who believe crude oil will increase in value relative to large-cap U.S. equities in one day or less.  FOL seeks to track approximately +200% of the daily return of the S&P Crude Oil - Equity Spread Total Return Index (before fees and expenses) by primarily establishing a leveraged long position in Light Sweet Crude Oil Futures and a leveraged short position in the E-mini S&P 500 Stock Price Index™ Futures.
