this is biotech, you need to have a strong stomach and hang in there for the long term.
Heard the same thing about isis and incy and than isis went from 7 to 63 and incy from 7 to 117.
Hang on, this is the kind of stock that could double heart beat. Look at isis, incy from 7 to 60, and 7 to 108. Only a fool would short biotech.
