up/down, up/down, completely random. Moves up 20+ cents should not be followed by double digit drops on no news either way. It really is funny how this stock is played. I'd rather this thing just lay flat for move a few cents, hate seeing the trading games at work. I'd like to think "games" are for kids but clearly not the case in today's stock market. Movement one way or another SHOULD be based on revenue/profit, hitting targets/beating estimates and future potential. In this case, bio, should be based on hitting key targets and potential. I just don't see it reflected here yet, we will though.
I'm sure some of the cause for low volume is people with shares are not unloading them. Why would you sell now if you own them? I would expect demand for shares to be higher then what is coming available, thus price increases, but then again, its too logical and the price seems to rarely reflect logic.
