Short sellers moved fast this week. Data from ORTEX as of August 31 shows several notable jumps in short interest — with geopolitical risk adding fuel.
HPK (HighPeak Energy) saw short interest leap to 43.1% of free float, up from 34.7% just one week ago — an 8.4 percentage point jump. With crude oil spiking past $90 on US strikes in Iran, bears are betting the small-cap energy firm can't sustain its run.
CAPR (Capricor Therapeutics) also surged to 45.2% SI% FF, up 8.2 points in seven days. Cost to borrow sits at 7.3% — a squeeze risk if sentiment flips.
KVYO (Klaviyo) jumped from 13.2% to 20.0%. That's a sharp move for a $2.6bn SaaS name. Availability remains plentiful at 697%, so shorts can still pile in easily.
NVAX is trending. Unconfirmed rumours of positive Matrix-M safety data circulated today. With SI% FF at 32%, any confirmed good news could trigger a sharp squeeze.
WOLF (Wolfspeed) stays deeply shorted at 72.1% of free float — with zero availability left to borrow. That's a powder keg. DTC stands at over 7 days.
