PTI had merger news which I found to be pretty weak and unwarranted for a big spike, which it had in the pre-market. It has a mid-range, large float which I like (44 million) and was hitting clear, heavy resistance from the recent past and also from since March. I felt comfortable shorting it and waiting for the drop. It was a slow pre-market, so I was looking for quick easy in and outs to hopefully be done for the day pretty early. PTI was one of those.
