How many ACAD you have? See, many don't understand if you only have 100 shares and a stock doubles who cares. I have a load of SNTS also very cheap, I make a lot of money on TSRX and SNTS over the past years and really recent on TSRX up until now. I am not going into every bio out there, is all I am saying and each can have it's seasons. ACAD is OK for now, I don't have any.
TTPH has a ways to go. I didn't buy it yet, but on watch.
