Jeff Black ProShares UlShrt China 25 ETF FXP-N DON'T BUY Oct 14, 2011

ProShares UlShrt China 25 ETF. Being an ultra-short, this is a leveraged inverse correlated play on the China index. Part of the challenge with any of the short or inverse ETF's is its daily tracking. Aon't always have tracking error there with respect to their underlying indices might do. (Not sure I got this last part right. – Ed.)
