The substantial holder notice from today shows that UBS have 5% of cgc stock. It also shows that they have borrowed a lot of that. The only reason i can think of to borrow stock is to short it.

We may see some price pressure in the coming weeks as UBS starts the short.

Look at RFG as a recent example of UBS shorting. It's done more than 10% since UBS reported they were a substantial holder and that they had borrowed stock.
