Short sellers made bold moves in the final week of August. Several mid-cap names saw double-digit swings in short interest. Here are the standout stories.
The Biggest Mover: HighPeak Energy
HPK saw the sharpest jump among stocks above $500M market cap. Short interest hit 43.1% of free float. That's up 8.4 percentage points in just one week. Bears clearly sense pressure in the US oil patch.
Capricor and Klaviyo Under Siege
CAPR now has 45.2% of its float shorted. That's up 8.2pp in seven days. The biotech's cost to borrow sits at 7.3% APR. Availability of shares to borrow is thin at only 39%.
KVYO is a surprise entrant. The marketing software firm saw SI jump from 13.2% to 20% of float. Bears appear skeptical of its valuation. Availability is very high at 697% — shorts have plenty of room to press.
Wolfspeed: The Chronic Short
WOLF remains one of the most battered names on the market. SI stands at 72.1% of free float. Availability has collapsed to effectively zero. Finding shares to borrow is near-impossible.
CoreCivic Catches a Bid from Bears
CXW jumped 5.3pp in a week to 15% shorted. The private prison operator faces renewed scrutiny. SI had been quiet — this spike is fresh.
Healthcare REITs in the Crosshairs
ORTEX flagged a 74.5% surge in short shares on NHI. That's one of the fastest weekly SI builds in the healthcare REIT space. Cost to borrow remains low. Bears are piling in cheaply.
