I believe that, increasingly, investors are beginning to see the potential of this little company and realize just how cheap the current sp is. Consequently, CLSN is now a noticeable blip on their radar and, thus, won't stay cheap for much longer IMO. You may find some dips here and there, but don't hesitate for too long -- soon its current sp will be left in the dust along with the day traders. But most importantly, what shares you are fortunate enough to acquire, I would hang on to. This is just my humble opinion. Disclosure: I am long $CLSN.
You could look at the options . A Sept. $4.50 is about .25 to .30 . But as of now it's out of the money . A $4.00 strike price would cost considerably more . If you go out to Jan. A $4.00 call would $1.00 . if the stock moves up 3 , 4 from here you could exorcise and buy the stock .
