$QSI bringing my average down, but at this point not sure if I should keep digging my own grave deeper 😔. Any advise or just hold where I’m at at $2.16 average. Thoughts?

$QSI Market cap is now $195 million. They have $265 million in cash. You could buy the entire company for $0 and put $80 million in your pocket. Yet, management remains totally silent. QSI's largest institutional shareholder owns 30 million shares, more than twice the shares of the next largest institutional owner. Yet, management has never revealed the identity of that shareholder. Maybe a shareholder lawsuit would loosen their tongues. If we don't get a name on the March earnings call, it may be time.
