Short sellers stepped up pressure on several notable names in the past week, with the biggest moves concentrated in a handful of stocks already under stress.
MMED (MiniMed Group) saw the sharpest increase among mid-caps. SI % of FF jumped 30 points in seven days to 70.5%. Shorts are betting against the medical device maker hard, and borrowing costs remain elevated at 17%.
LCID (Lucid Group) climbed from 50.6% to 58.1% short interest over the same period. The EV maker has struggled to prove its path to profitability. Bears are not backing off.
GRPN (Groupon) sits at 71.3% short, up 7.8 points week-on-week. Days to cover stand at 9.1. With the stock down 16% over three months, shorts see little reason to cover.
WOLF (Wolfspeed) remains one of the most heavily shorted semiconductors at 81.3% of float. The silicon carbide chipmaker has shed 38% in three months as demand concerns weigh.
BA (Boeing) was in the news after winning the US Navy's next-generation F/A-XX fighter competition. Short interest there ticked down slightly to 1.9%.
On the pharma side, LLY (Eli Lilly) reported striking TRIUMPH-2 trial data for retatrutide, showing nearly 50 lb average weight loss. Shorts have retreated, with SI barely above 0.8%.
Taiwan's export orders hit a record $103bn in August 2026, nearly doubling year-on-year, according to ORTEX alt data. That backdrop supports demand for the chips and electronics that Wolfspeed and peers supply, yet bear positioning in the sector shows no sign of easing.
