Short sellers stepped up pressure on MMED and CHWY in the week to October 5, with both names posting sharp rises in short interest.
MiniMed Group saw its short interest jump 9.5 percentage points in seven days. It now sits at 80% of free float, one of the highest readings in the US market. Its ORTEX short score stands at 90, with availability near zero. Shares to borrow are essentially gone.
CHWY added 4.2 percentage points over the same period. Short interest reached 69.8% of free float. The stock is down 14% over three months.
WOLF, the troubled SiC chipmaker, held near record highs for short interest at 81.2% of free float. It barely moved week on week, but availability remains at zero. That is a squeeze risk worth watching. Analyst commentary this week pointed to strength masking pain in broader semiconductor names, adding pressure on the sector.
TLN, Talen Energy, was the standout mover in the power sector. Short interest jumped 5.1 points to 11.5% of free float in seven days. The nuclear power theme has drawn heavy attention from traders, and ORTEX alt data shows reactor output at Vistra (VST) running 10 standard deviations above its own history as of September 9, a signal that shorts are watching supply dynamics carefully.
HTZ and GRPN both saw marginal short covering. Neither has meaningfully reduced its heavy short burden, with both still above 69% of free float.
US payrolls hit a record 159 million in September, which may keep consumer discretionary names like Chewy in focus for bears betting on spending fatigue.
