Holy shit 16 pages of this. This is truly astonishing
I stopped reading after 3 posts, but I am just going to say that there are people a lot smarter than almost all of you who have already modeled this to make sure no "arbitrage" opportunities exist.
In truth FAZ/FAS is no different than any other pair strategy, but people jizz their pants just because it's 3x on something that just in the past few weeks people have been getting a SLIGHT idea for the fair value.
I can tell you that even though you may pick up a few pennies here and there it's probabilistically impossible for you to come out ahead if you make enough trades on either of these stocks.
You can think I'm a jerk, but you'll thank me for this 2nd grade wisdom someday.
