Short sellers made aggressive moves this week. Data as of August 27 shows several notable spikes in short interest across tech, energy, and biotech names.
SPCX — Space Exploration Technologies — saw SI jump from 18.0% to 23.9% of free float in just days. That's nearly a 6-point rise in a week. With a $1.9 trillion market cap, bears are making a bold bet against Elon Musk's rocket company.
KVYO (Klaviyo) nearly doubled its short interest. SI leapt from 13.0% to 19.9% of free float — a 6.9-point jump. Options data flags puts piling into chip-adjacent names this week, and Klaviyo is catching the same wave.
HPK (HighPeak Energy) surged to 42.4% SI from 33.8% last week. That's an 8.6-point spike. Bears are targeting oil names as the Iran conflict reshapes energy markets.
CXW (CoreCivic) stands out too. SI jumped sharply from 9.8% to 15.3% — a 5.5-point move — making it one of the fastest-rising names this week.
On the structural high end, WOLF (Wolfspeed) remains the heaviest-shorted mid-cap at 73.7% of free float. Availability sits at 0%, meaning shorts are fully squeezed on borrow.
EVCM (EverCommerce) carries the highest short score at 94.5. Its cost to borrow hit 38.2% APR — a signal bears are paying up to hold positions despite tight availability.
