Does it include options, futures, swaps, and other instruments? If the ban includes all these instruments, how can a "short ETF" accomplish its task? Or, let us say if I want to short China through FXP, then all of a sudden China puts a ban on shorting. How does the FXP etf go about doing its task of being an inverse of FXI? Input please. Not that i care about shorting, but was just wondering how will all these new government rules will work. And if the etf's get screwed.
