I think $3 is in play as long as there's no news to douse the flames. On the other hand, a 800k volume day with a high of $2.98 and close at $2.93 would set a nice table for a news release on Wednesday.
Having said that...I think CTIX will go over $3.00 tomorrow at some point. This stock is gaining attention exponentially. Nobody wants to get left behind on a double or triple in a week (not expecting that but people dream...see buyout speculation).
