Short sellers made notable moves this week. SPCX — Space Exploration Technologies — saw its SI % of Free Float jump from 21.8% to 29.4% in just seven days. That's a 7.6-percentage-point rise, one of the largest weekly increases among large-cap names. Shorts appear to be fading the $1.2 trillion space giant despite moderate borrow costs of just 0.56%.
GME also flashed a spike. Short interest hit 7.2% of free float on September 23, up sharply from under 1% a week earlier. The stock continues to attract speculative attention on social platforms. Availability is ample at 240% of SI, so borrow is not yet constrained — but the jump is worth watching.
WOLF remains one of the most structurally shorted names. The chip maker sits at 80.3% SI % FF with 9.7 days to cover. The stock is down 41% over three months. Cost to borrow is low, suggesting the trade is crowded but not yet painful.
Pet retailer CHWY holds 74.9% SI % FF. That figure has climbed steadily from 57% in late August. Short sellers have been adding consistently.
FLWS — 1-800-FLOWERS — sits at 79.6% SI % FF with a punishing 31.4 days to cover. Any positive catalyst could squeeze holders hard.
Braveheart Bio (BRVE) tops the overall list at 367% SI % FF, up 144 points in a week. That extreme reading signals a highly contested float.
