Bears Pile Into MiniMed and SpaceX; Chewy Shorts Retreat

Short sellers made bold moves this week. Data as of September 24 tells a striking story of divergence.

Biggest new short target: MMED. MiniMed Group saw its SI % of Free Float jump from 38.5% to 68.3% in just seven days — a 29.8 percentage point surge. With only 2.3% availability of short interest remaining, borrowing new shares is nearly impossible. Cost to borrow sits at 18.2%. A squeeze could ignite fast.

SpaceX stays in the crosshairs. SPCX short interest climbed to 30.6% of free float, up 9.8 points on the week. Bears remain committed despite a $1.2 trillion market cap. Availability is loose at 159%, so new shorts can still get in.

WOLF stays extreme. Wolfspeed carries 80.4% short interest. Zero shares are available to borrow. Any positive catalyst could send this semiconductor name sharply higher.

LUCK under pressure. Lucky Strike Entertainment carries a ORTEX short score of 94.8 and 30.6 days to cover. Cost to borrow hit 32.8%. Bears are paying a steep price to stay short.

Chewy shorts covered. CHWY SI fell from 74.1% to 67.2% over the week. Still very high, but the directional shift matters. 433% availability suggests ample shares remain if bears want back in.

Chip headlines dominate the news cycle, with the S&P 500 and Nasdaq closing lower as semiconductor stocks remain volatile.
