robs.. I think in the grand scheme of things one needs to consider the upward momentum of BIOF. The sector also looks strong (price of corn if falling) so I see the up trend continuing for PEIX. And the technicals show an up trend with PEIX as well (EMA/10 > SMA/20 > SMA/30. I chart this stuff.
I'm also a fundamental trader so I like the reasonable float. Don't like the low cash position though. But the debt is better than BIOF. Love the beta. So we ride the BIOF coat tail for now.
My thinking is that traders will be taking profits on BIOF and migrating over to PEIX thus pushing the PPS higher.
