Price Context

2026-03-20 to 2026-08-14

Squeeze Radar

Elevated short interest becomes most interesting when price strength forces shorts to defend or cover.

Bearish Conviction

Rising short interest alongside weak trend can mean the bearish trade is being reinforced, not trapped.

Crowding

Latest short interest is 37.4M shares and days to cover is 8.69.

Divergence

Short interest rose while price rose. Bearish positioning is adding into strength, which can create squeeze pressure if the chart keeps improving.
