Of course it will go that low. Ultimately, it has to. It is a mathematical certainty.
While there may be a reverse split before FAZ reaches that level, it will eventually get there after correcting for the R/S. Neither FAZ or FAS are an appropriate investment based upon what you think may, or may not, happen with the macro-ecomony.
It doesn't matter if you are a bull or a bear, both FAZ and FAS ultimately must lose value over time.
