no worries . cannot count on catalyst sometimes. They may have announced they got a P3 approval on a cure for cancer, but if everyone was watching $ETRM and $BIOC and tons of other moving tickers today so the stock wouldn't have responded much. Wait for volume for conformation. I can understand the disappointment though.
Its not only the volume, it is the volume in relation to the float. I am sure Google had more volume to day than MSTX too but it would not have affected the stock if it was a large float co.
