Actually it is, i have invested in just a couple of biotech at a time including RAC until recently and am re looking at it now.
Always find myself getting too excited and put in a lot more than i should. The only times i managed to make a small bit of profit were the times i got out too soon, missed the top, but in hindsight, escaped huge losses had i stayed. Granted, the ones i sold out can still hit big time on the future.
Rare chance to get to hear from a biotech CEO regarding biotech investments. RAC had been the first biotech I bought in big (in my portfolio).
