Hi, I am wondering if anyone here has been able to short any of the ultra or 3x ETFs for more than one day. If you have: What ETF did you short? How many days were you short? Did the shares eventually get called back by the brokerage before you were ready to buy them back? And finally did you pay a hard to borrow fee. If so how large was the fee? Of course feel throw in any other information you'd like about the short ETF experience and thanks for your time.
