Short sellers made sharp moves this week. Data to July 10 shows some striking 7-day swings worth watching.
SPCX — Space Exploration Technologies — saw the biggest jump. Short interest leapt from 3.7% to 25.2% of free float in just seven days. That's a 21.6 percentage point spike. With a $1.1 trillion market cap, any squeeze here would be dramatic.
HTZ climbed too. Hertz now sits at 69% SI % FF, up 8.3 points on the week. Availability is zero — there are no shares left to borrow. Cost to borrow is just 1.6%, suggesting the crowded trade hasn't yet become expensive.
TNGX — Tango Therapeutics — hit 68.6% SI % FF, up 14.4 points. Its availability is huge at 646%, meaning shorts can still add aggressively.
On the other side, WOLF — Wolfspeed — saw shorts cover. SI dropped 16.5 points to 82.7%, still extremely elevated but clearly easing. The chip backdrop matters: Asian chipmakers dominated financial headlines this week, with AI-linked names selling off hard.
MQ — Marqeta — saw short interest collapse from 14.5% to just 2.2%, a 12.3 point drop. Shorts essentially fled the stock.
Bank earnings kick off Tuesday. JPM, GS, and WFC all report — a catalyst that could shake positioning across financials.
