sure is a frustrating stock this GERN.. I mostly just trade and seldom hold overnight, but I still try to stick with fundamentals to a degree which is why I always gravitate to GERN over STEM and ASTM.. but its amazing, like mainhiker always jokes- STEM and ASTM make double percentage moves half the time off the GERN news releases : )
its probably nothing more then the fact that ASTM and STEM are half the price so traders gravitate to them.. also the liquidity.. but I cant play that garbage!!!
