Short sellers made a dramatic move into SPCX last week. Short Interest % of Free Float jumped from 3.65% to 25.22% — a gain of over 21 percentage points in just seven days. SpaceX's $1.1 trillion market cap makes this one of the most notable SI spikes of the week.
Biotech TNGX carries the highest absolute short interest in the data. Tango Therapeutics sits at 68.6% SI of FF. That climbed another 14 points week-on-week. Availability is sky-high at 646%, meaning borrow is plentiful — shorts face no squeeze pressure yet.
The squeeze risk story is elsewhere. EOSE — Eos Energy — has utilization near 97%. Availability has hit zero. Shorts cannot find shares to borrow. That is a classic squeeze setup.
WOLF tells the opposite story. Wolfspeed's SI fell sharply, dropping 16.5 points to 82.7% of FF. Cost to borrow stands at 8.8%. Availability is zero. Bears covering here face real pain.
Trucking firm KNX drew fresh attention. Knight-Swift short interest surged 32% over the past week to 5.96% of float, even as analysts raised price targets.
Iran-US hostilities are pushing oil higher. That geopolitical pressure is adding fuel to energy shorts across the board.
