WOLF has become the most extreme short in the US market. Short interest hit 117.5% of free float on May 25. That figure rose nearly 10 percentage points in just one week. Availability stands at zero — there are no shares left to borrow.
The semiconductor firm has been under sustained pressure amid ongoing losses and high debt. Bears keep piling in.
WBI — WaterBridge Infrastructure — saw the sharpest weekly jump among liquid names. SI climbed from 28% to 43% of free float, a 15-point move in seven days. Shorts are clearly betting against the midstream energy newcomer.
RHI (Robert Half) also drew fresh bearish attention. SI rose to 30% of free float from 27% a week ago. The staffing sector remains under pressure amid a cooling labor market.
On the other side, WYNN saw shorts exit fast. SI fell from 15% to 11.7% of free float in a week, a 3.4-point drop. Short covering at the casino giant points to renewed confidence. Availability sits at 661%, meaning plenty of room remains to short — but fewer are choosing to.
KALV (KalVista Pharma) saw the biggest SI drop overall — down 9 points to 25% of free float. Short sellers appear to be retreating after earlier bets. Availability has exploded to 1,422%.
Popular retail names GME, AMC, and MSTR remain stable, with short interest barely moving week-on-week.
