Short interest data as of July 13 reveals some sharp moves across US markets. The biggest story is SpaceX (SPCX), where SI % of Free Float jumped to 26.1% from just 3.7% a week ago — a 22-point leap. That's one of the largest single-week builds seen on any large-cap name. With a market cap topping $1.1 trillion, this reflects serious institutional conviction against the space giant.
TNGX (Tango Therapeutics) remains the most shorted mid-cap name in the database at 68.4% of float, up another 14.5 points in seven days. Bears show no signs of letting go.
UAA (Under Armour) also attracted fresh shorts, with SI rising to 31.6% from 26.3% — a 5-point increase. The apparel brand continues to struggle.
On the unwind side, (Wolfspeed) saw shorts cover hard. SI collapsed from in a week — nearly 20 points of covering. That's a notable squeeze signal.
GME sits at 13.6% of float — still elevated versus meme-era norms. TSLA and NVDA remain lightly shorted at 3% and 1.3% respectively.
Meanwhile, IBM stock tumbled today after missing Q2 estimates — yet its SI is only 3.7%, suggesting bears had largely not anticipated the miss.
