Well, there's a surprise! PRTA up about 90% this morning after good results for Alzheimer's drug at BIIB and Alsai. I don't know what the connection is though Alzheimers and ameloid plaque has been the area of concentration for PRTA all the way back to the 1980's when they were ELAN. I did not expect this at all and sold one lot last week at $32. Price now $57. I also own some puts to take shares at $35 in December which apparently are going to expire worthless. But by lucky break I also had calls sold at $35 and $40 which expired last week worthless. I should also remember that BIIB wound up owning parts of ELAN some years ago after which scientists from Elan formed up PRTA though the details on that are fuzzy to me. They still occupy some of the Elan buildings in S. San Francisco I believe and I walked through there during the last alzheimers craze.
