This month's big Geron (GERN +11.9%) rally takes another leg higher. With today's move, the shares are up around 151% in September.
At least one trader in the options market thinks the rally has further to go: The purchase of 3K November 3 strike calls was partially funded by the sale of 3K November 5 strike calls. Although the upside in this trade is capped, there's still a nice profit to be made if GERN trades up to or above $5 by expiration.
A bet for GERN is a bet on imetelstat in myelofibrosis — look for interim data at ASH in December.
