Short interest shifted sharply across several sectors this week. Data from ORTEX as of August 27 shows clear trends — bears piled into biotech and marketing tech, while covering in others.
CAPR saw the biggest weekly jump. Short interest hit 45.6% of free float, up from 36.4% — a 9.2 percentage point surge in just seven days. Capricor Therapeutics bears are betting hard against the small-cap biotech.
Marketing software firm KVYO wasn't far behind. Klaviyo's SI leapt from 13% to 19.9% of FF in a week — nearly doubling. Short sellers appear skeptical of its valuation despite solid revenue growth.
SpaceX stock SPCX also drew fresh attention. SI climbed from 18% to 23.9% of FF, notable given the company's $1.1 trillion market cap. Bears seem undeterred by its scale.
On the other side, CHWY saw heavy covering. Chewy's SI fell from 59.1% to 47.6% of FF — a drop of 11.4 points. Short sellers retreated as the pet retailer showed resilience.
also saw shorts cover. Wolfspeed's SI eased from 80.7% to , though it remains one of the most-shorted large names in semiconductors. Availability sits at zero — no fresh shares to borrow.
ELF — e.l.f. Beauty — halved its short interest from 14.1% to 7.1% of FF, suggesting bears are abandoning that trade entirely.
