Shorting a biotech that just had another sucesful throat implant on earnings day. Even though they are not FDA approved to sell anything, just the idea that a new treatment can work is enough for a stock to go up. Lesson, do not short BIO stocks.. But this stock did come down and it was actually an accident that I exited my position because I was trying to set a stop loss at 9.01 but it got triggered at 8.83 because I screwed up the order.
