Short sellers have been busy this week. Cerebras Systems saw the biggest short interest jump among large-caps. SI % of FF leapt to 27.7% from just 6.25% a week ago — a 21-point spike. Availability sits at only 20%, signalling heavy demand to borrow.
Hertz Global remains a favourite target. SI hit 45% of free float, up from 39.6% last week. With availability at just 19%, new short positions are getting harder to put on.
Birkenstock is another notable mover. SI climbed to 30.9% from 22% in seven days. The cost to borrow is a steep 19.3% APR. Available shares to lend stand at near zero — just 0.03% of SI. Squeeze risk here is real.
On the cover side, Wolfspeed bears pulled back hard. SI dropped from 117.9% to 99.8% — an 18-point retreat. That's a sharp short-cover in one week.
America's Car-Mart grabbed headlines today after shares crashed over 62%. SI stood at 34.8% before the collapse. Short sellers will be sitting on large gains.
GameStop holds at 13% SI. No major changes. The meme crowd watches closely but bears aren't adding aggressively here.
