I agree, short squeezes don't happen very often, in my experience. But - ANY has about 30 days to cover, the pps keeps rising, more and more breaking news are coming out... I think expecting the squeeze is realistic.
I can see short interest on tmx website for the last 3 months only. When did it start accumulating?
In the US, SEC publishes bi-monthly "failure to deliver" reports. What about Canada? It would be interesting to see if they have any failures to deliver. OVRL started having some last month.
