APOP has very little trading volume on Nasdaq. The “average volume” figure is badly skewed by the 3.8M shares traded on 1/4/17, when APOP rose 27% on the heels of an “n=3” PR purporting to show proof of concept: https://finance.yahoo.com/news/cellect-announces-breakthrough-clinical-results-124500349.html If one were so inclined, it might be possible to accumulate a sizable position over time, but it would be tough to unload if things didn’t work out. I don’t have an educated opinion on the company’s technology. If anyone does, please post.
