Short sellers made bold new bets this week. The moves span healthcare, aerospace, and consumer names — with some eye-popping jumps in just seven days.
MMED (MiniMed Group) saw the biggest mainstream surge. Short interest hit 68.3% of free float, up from 38.5% a week ago — a near-30 percentage point spike. The medical device firm carries a $5.6B market cap and a short score of 90. Availability is razor-thin at just 2.3%. That is a dangerous setup for trapped bears.
SPCX (Space Exploration Technologies) also drew heavy new shorts. SI jumped to 30.6%, up nearly 10 points in a week. The stock is down 3% over three months. A director dumped $411M of NVDA stock this week — a headline that rattled chip sentiment broadly.
SSMR (Sunshine Silver Mining) was a stealth mover. SI rocketed from just 2.6% to 27.3% in seven days. That is a 24-point leap, suggesting a coordinated short thesis is forming.
NKE drew fresh attention as earnings season opens. SI climbed to , up 1.8 points from last week. Options flow is heating up into the print.
LUCK (Lucky Strike) remains deeply shorted at 17.1% with 30+ days to cover — one of the most dangerous squeezes on the board if sentiment shifts.
EVCM (EverCommerce) holds a short score of 94 with near-zero availability at 0.4%. Any positive catalyst could squeeze hard.
