Short interest in MMED (MiniMed Group) hit 91% of free float as of October 6. That is up from 74.5% just one week earlier. The 16.5 percentage point jump in seven days is the largest move tracked across mid-cap US names. Cost to borrow stands at 29.3%, signalling serious demand to hold the short.
TLN (Talen Energy) also drew fresh attention from bears. Its SI % FF nearly doubled over the week, rising from 6.6% to 11.9%. Talen is a nuclear power generator. Notably, ORTEX Alt Data shows reactor output for SO (Southern Company) ran 10 standard deviations below its own historical average in early September. Nuclear output volatility is on traders' radar across the sector.
UPBD (Upbound Group) climbed from 15.2% to 19.5% short. The rent-to-own retailer faces pressure as captive finance recoveries rose 44% year-on-year in Q2 2026, while credit loss provisions climbed 27%. Bears appear to see more stress ahead for consumer credit-dependent models.
CHWY remains the most heavily shorted large-cap consumer name at 68% of free float, though that figure was nearly flat on the week. SOUN (SoundHound AI) holds 41.6% short with a rising cost to borrow of 2.8%.
BKNG (Booking Holdings) saw a fractional SI dip, though news of a potential FTC action over misleading affiliate ads kept the name in focus. TSLA and NVDA both sit below 2.5% short, with no meaningful change on the week.
