Short sellers turned aggressive this week. Several names saw dramatic moves in short interest — here are the standouts.
BRVE (Braveheart Bio) tops the charts. Short interest hit a staggering 648% of free float — up from 237% just seven days ago. That 411 percentage-point spike is the largest weekly jump in the dataset. Borrow availability sits at 95%, so bears can still get in.
MMED (MiniMed Group) is the next biggest mover. SI jumped from 41% to 68.5% of free float in one week. Despite a 40% price rally over three months, short sellers are pressing harder. Cost to borrow is 17%, and only 2% availability remains — the trade is getting crowded.
SSMR (Sunshine Silver Mining) went from almost nothing to 24% of free float in a week. That's a sharp new bearish bet on a miner.
WOLF (Wolfspeed) holds at 81% of free float shorted — one of the highest readings for any NYSE-listed stock above $1B market cap. Borrow availability is essentially zero. A short squeeze would be violent.
PATH (UiPath) fell sharply on Monday. Short interest is steady at 26.7% of free float, but a downgrade and negative headlines may draw fresh bears.
On the ETF side, VUG saw short interest fall 31% in a week — growth ETF pessimism is fading fast.
