Short sellers made bold moves this week. Cerebras Systems saw the biggest single-week jump among mid-to-large caps. Its SI % of Free Float leapt from 6.25% to 27.71% — a 21.5 percentage point surge in just one day. Availability sits at just 20%. That squeeze risk is real.
lululemon athletica is also drawing heavy attention. SI % FF hit 6.9%, up 20.6% in one week — its highest in 30 days. Analysts cut price targets following a weak earnings print. Bears are betting the pain continues.
Birkenstock shorts are building too. SI % FF climbed from 22% to nearly 31% in a week. The sandal brand has been quietly creeping up short interest lists for weeks.
On the other side, Wolfspeed saw shorts cover hard. SI % FF dropped from 118% to 100% over seven days. Cost to borrow remains steep at 8.7%. Shorts are finding it expensive to stay in the trade.
Hertz remains a favourite for bears. SI stands at 45% of free float — up 5 points this week. GameStop sits steady near 13%, still a social-media fixture but showing no major new moves.
