I've been in stocks with documented short issues. Poet stock does not act like those did. I have felt for years that short talk is just an excuse for the share performance.  It's a favorite whipping boy for those who can't believe their analysis of a stock is somehow flawed. 

I think there was some funny business associated with the 2016 financing fiasco, but other than that, I'm pretty sure shorting does not explain our undervalued status.
