Talon was open for trading during the panel and the shares went as high as $1.10 before the final vote count was announced. But the stock's gains quickly evaporated with Talon closing Wednesday up 7 cents to 81 cents a share. As I write this column on Thursday, Talon is down 6 cents to 75 cents. Talon trades on the bulletin boards so it's going to be a volatile stock, but tweets of biotech traders Wednesday suggested few were willing to guarantee Marqibo's ultimate approval with any degree of confidence. If Talon is your kind of stock, I'd say trade carefully. --Written by Adam Feuerstein in Boston. >To contact the writer of this article, click here: Adam Feuerstein. >To follow the writer on Twitter, go to http://twitter.com/adamfeuerstein. >To submit a news tip, send an email to: email@example.com.
