Short sellers made a decisive move this week. MMED (MiniMed Group) saw its short interest leap to 99% of free float, up from 77.6% just five days ago. That is a 21-percentage-point jump in under a week. Availability of shares to borrow has collapsed to just 0.4% of short interest. Cost to borrow sits at 30%.
LEN (Lennar) also drew fresh attention. Short interest rose from 10.3% to 14.1% over the same five-day window, the sharpest move among large-cap names. Lennar carries a $15.8 billion market cap, making this a sizeable bet against the US homebuilder.
NYT (New York Times) climbed from 9.6% to 13.3% short. GAP moved from 12.6% to 16.1%. Both names saw short interest rise more than 3.5 percentage points in five days.
(Hertz) remains heavily shorted at 71% of free float. Shares available to borrow have dried up entirely.
WOLF (Wolfspeed) holds at 81% short interest with a days-to-cover ratio above 11. It remains one of the most challenged names in semiconductors.
MDT (Medtronic) saw a sharp relative move, doubling from 1.6% to 3.6%. ORTEX alt data shows Medicare Advantage penetration hit a record 51.1% in June 2026, covering 36.1 million beneficiaries. That structural shift may be sharpening bearish attention on medical device revenue.
