WSTG...Could be a number of reasons why he sold those shares. Hard to tell. He's been a director for quite sometime. I know one thing, a lot of tech stocks have been doing quite well lately including WSTG. (Heck, PLUS reports tomorrow and it's up $4+ today).
What I like about WSTG is they are well diversified within the company for transitioning into this worldwide work-at-home atmosphere...
