ProShares Ultra SmallCap600(AMEX:SAA)

SAA, as a levered product, is not a buy-and-hold ETF, its a short-term tactical instrument. Like many levered funds, it delivers its 2x exposure only for 1 day. Rebalance your exposure if you want the multiple for longer periods. SAA offers 2x levered exposure to 600 companies that span mid-cap, small-cap and micro-cap territories, i.e., the S&P 600. Eligible securities are screened through a process that factors in liquidity, price, market capitalization, financial viability and public float. As a short-term instrument, total costs associated with using this ETF are heavily weighted toward trading costs.
