comparison o two emerging biotechs

Two stocks I invest in and i'm sure many other posters do as well, are ACL and TIS, both closed at 0.35 yesterday 6/2/12. I wonder where each will be in relation to the other in 12 months or 24 months. ACL jumped ahead on news today but i'm certain TIS will soon catch up on it's own progress reports. I really don't mind which stock out does the other I think they both hold lots o promise in this year, that many experts seem to think is the year o the biotechs
