I agree that some of the price targets are "enthusiastic", but they are certainly POSSIBLE.....if you doubt it, look at historic prices, how was that obtained????......FAZ is a 3x inverse of the fin index, if the index again reaches similar lows, FAZ should react according......(minus some ETF erosion, of course)....
PS: as a trade off for the erosion, unlike a normal short position there is no worry about losing more than 100% of your investment.....
