I re-bought this pump after realizing my mistake and wanted to hold it for longer. I sold some each day on the way up and got down to half size before it started collapsing. It was pretty illiquid however and I could hardly get any fills. I tried to dip buy it and even though it technically bounced, there wasn't much trade volume and the spread was so wide that it wasn't possible to profit from it. The bounce eventually failed and I had to take a loss with my remaining shares.
