Bought this stock with some incredible alzheimer's news pre-market, because I saw level 2 bids and asks would cause it to gap up a lot. Thought there would be a morning spike. After I got my position, I looked at the last time it spiked big, and saw that it gapped up and struggled, and slowly trailed off all day. I saw it was doing the same thing this morning so I sold for a tiny profit. Good choice, because it fell off a cliff shortly after.
