How could the so called "UltraShort (2x) FTSE/Xinhua China 25 ProShares " with symbol FXP tumbled $5 dollars to $95 this morning while the China stock market closed down to 8 month new low last night and the S&P 500 also went down this morning?? And at the same time, most of the major China stocks traded in NYSE were down, and another (long) ETF, CAF _ the Morgan Stanley China A Sh Fund, fell about a dollar.
Is FXP an "Ultra Short" or "Ultra Long" ETF ??
I believe it's not the first day FXP behaves like this. What's going on here, can anybody explain?
