Short sellers are making bold moves heading into September. ORTEX data through August 27 shows several stocks hit with fast-rising short positions. Here are the standout moves.
Klaviyo Jumps Into the Crosshairs
KVYO saw its SI % FF leap from 12.96% to 19.86% in just seven days — a 6.9 percentage point jump. That's the biggest weekly rise among large US names. Bears are clearly betting the marketing software firm's valuation can't hold.
SpaceX Short Interest Climbs
SPCX sits at 23.9% SI % FF. Bears added 5.9 percentage points in a week. The stock draws strong retail and social media interest. Bears are taking the other side of that hype.
EverCommerce: Squeeze Risk Rising
EVCM carries an ORTEX short score of 94.5 — the highest in the market right now. Its cost to borrow has rocketed to 38.2% APR. Availability stands at just 1.5% of short interest. Borrow is extremely tight. Any positive catalyst could spark a violent squeeze.
HighPeak Energy in Focus
HPK shorts rebuilt aggressively. SI % FF jumped 8.6 points to 42.4% in seven days. ORTEX News flagged the move today, noting options sentiment turned bullish despite the short rebuild — a split market signal.
Meme Stocks Stay Quiet
GME SI % FF sits at 14.7%. TSLA is at just 2.5%. NVDA bears remain subdued at 1.2%. Reddit's favourite squeeze targets look quiet for now.
