Yep. And SAPX gives more of a rollercoaster-ride than BPAX, that's for sure.
But the rides up are really worth-while, so I tend to switch $$ back and forth whenever needed.
Shorting SAPX is a dangerous game, as this can really fly, and with news around the corner it has potential to stay well above a dollar (once it gets there).
I'm long and strong in BPAX, holding a really nice core. I know what this will bring us!!
