Drechsler-Drechsler 2016 RFS -- Shorting at Close Range: A Tale of Two Types.

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.
