28Elevated short interest becomes most interesting when price strength forces shorts to defend or cover.
Bearish Conviction
14Rising short interest alongside weak trend can mean the bearish trade is being reinforced, not trapped.
Crowding
27Latest short interest is 11.5M shares and days to cover is 5.35.
Divergence
20Short interest fell while price fell. Shorts are covering despite weak price action, which can suggest the easy bearish pressure may be fading.
