Many ultra shorts have a natural drip on them. As in poker it's like a rake. Look at a long term chart of FAS and FAZ. They are triple long and shorts of in finacials. Look at a 1 year chart of fas and faz, you would think if one was up 40 percent the other would be down 40 percent, BUT one is down 18% and the other 35%. My point is down go long ultra etfs. Better to go short IMO>
All these ultra funds, short or long have a rake. They cannot follow 2x or 3x for more than a few days out. BTW, Friday's close was strange, DDM popped on 100 shares from 66.97 to 67.21 at the last second but the bid/ask was 66.97 and 66.99 Something took it up artificially. Shorts watch out Monday all this free money is driving up the DOW.
