RE:RE:6M shares traded at the last minute
There is many ways to short a stock. As I mentioned before the earnings, I shorted covered HEXO with some calls with the expectation that Hexo will go down after the earnings.
Shorting is not only about selling high and buying back at a lower price. It sure is more rewarding to do it that way but only if the stock really goes down otherwise you could loose your shirt if it doesnt happen (naked short).
Covered short are a way to cash in some money with the possibility of not loosing your position at the end of the contract. I doubt that Hexo is victim of over shorting as the volatility is not high enough and it doesn't appear on any top TSX shorters report :
