Short sellers turned aggressive this week on several well-known names. Chewy saw the sharpest move among large-cap stocks. Its short interest jumped 17.5 percentage points in seven days. It now sits at 87.3% of free float, one of the highest readings among US names with a market cap above $500M.
Wolfspeed is close behind at 88.9% of free float. Its SI rose 7.6 points in the same period. Shares are down 17% over three months. Zero shares are currently available to borrow, locking out any new short positions for now.
Medtronic was another surprise mover. Its SI leapt from 1.8% to 10.1% of free float in a week, an 8.3-point swing on a $117B market cap name. That kind of move in a large-cap healthcare stock stands out.
EverCommerce carries the highest short score in the software space at 95.6. Its cost to borrow hit 191% APR. Availability is near zero at just 0.1% of SI, making fresh shorts extremely costly.
Tesla sits far lower at 2.5% of free float with a negligible cost to borrow. Colorado battery-electric vehicle registrations rose for a fourth straight month in July 2026, per the Atlas EV Hub, a dataset ORTEX tracks as a leading indicator for Tesla revenue. Tesla reports earnings on 21 October.
Fluence Energy and SailPoint both added over 5 points of SI in the week. Shorts are not yet done rotating into growth names with stretched valuations.
