Short sellers turned aggressive on WOLF this week. The chipmaker's SI % of Free Float jumped 6.5 percentage points in seven days to 57%. Shares to borrow are near impossible to find — availability sits at just 0.75% of short interest. Bears are betting heavily on continued pain for the troubled SiC semiconductor maker.
ADT also drew fresh short attention. Its SI % FF rose 3.2pp to 9.9% over the same period. Security services may look secure, but shorts disagree.
On the other side, short covering dominated Avis Budget Group. CAR saw its SI % FF drop 8.2pp to 38.7% in a week. That's a major unwind for one of Wall Street's most crowded short trades. KalVista Pharmaceuticals (KALV) shed nearly 9pp of short interest after a sharp rally.
In tech, ARM is in the spotlight after news of AI supply constraints hitting its growth story. Bears hold 11.4% of its float short. PLTR carries just 2.6% SI — shorts have largely given up fighting that rally.
Frontier Airlines (ULCC) saw shorts trim positions by nearly 2pp. Yet the stock remains 36% shorted. Any squeeze catalyst could move it fast.
