Short Pressure Overhang Short
In plain terms
When informed short sellers maintain heavy positioning for weeks without triggering a squeeze, the persistent overhang is a reliable bearish signal.
How it works
Persistent short overhang (high short volume as a fraction of total volume, sustained over 4+ weeks) without a squeeze signals ongoing informed bearish positioning. The short overhang depresses price gradually as shorts steadily sell into any strength.
