Haven't played with this in a while, but timing indicates another gap up Monday, a bull flag dip for a couple of days and rally into the Fed meeting.
If the Feds don't cut rates (which I do not expect them to) then the dollar will go up. This ETF is not currency hedged so if USD/MXN goes up, this goes down....
You can see USD/MXN coiling on the monthly chart, pay attention to the exchange rate if you're in this long term.
