Short sellers made bold moves this week. Cerebras Systems saw the biggest jump — SI % of FF leapt from 6.25% to 25.6% in just seven days. That's a three-fold increase. The AI chip firm is clearly drawing skeptics.
The rental car sector is under heavy fire. Avis Budget sits at 45.8% SI % FF, up 6.2 points in a week. Hertz is close behind at 44.5%, rising 4.6 points. Both names featured in today's ORTEX market recap alongside insider activity concerns.
Birkenstock is also drawing bears. SI % FF hit 30.2%, up 8.4 points. Cost to borrow spiked to 16.7% APR — one of the highest in the market. Available shares to borrow stand at just 3.4% of short interest. That is dangerously tight.
On the other side, Wolfspeed saw shorts cover. SI % FF dropped from 112% to 95.7%. Zero availability remains though, keeping the squeeze risk alive.
Tesla stays lightly shorted at just 2.7% SI % FF. Despite heavy social media chatter around Elon Musk's empire, short sellers are not positioned against it.
