Cannabis had its own version of the same story, running on the same fuel.
Tilray carried very high short interest going into 2021, with the cannabis sector broadly out of favour after years of disappointment.
It squeezed hard in February 2021 as retail attention rotated out of the original names and into any sector with the same structural setup.
Once traders understood the mechanics, they stopped caring what the company did. The screen was short interest, float and sentiment, not industry.
The playbook generalised. What started with one video game retailer became a method applied across the whole market.
Evidence that the squeeze was a technique, not a single trade.
