Markets Wrap: Bears Circle, Insiders Cash Out

Wolfspeed Remains the Most Dangerous Short

Wolfspeed is the defining story of the week for short sellers. Short interest hit 129.9% of free float — up from 103% seven days ago. Zero shares remain available to borrow. Borrow costs sit at 8.7% APR. That combination of extreme positioning and zero availability makes a squeeze technically possible at any moment. Options traders are watching the July 17 expiry chain closely.

WBI's 54-Point Weekly Surge

WaterBridge Infrastructure posted the biggest single-week short interest jump. SI leapt from 31.7% to 85.5% of free float — a 54-point move. Few names outside of distressed situations see moves that large in seven days.

Heavy Insider Selling at NVDA and ASTS

NVIDIA independent director Mark Stevens filed sales totalling over $400 million in June. The trades came near recent price highs. AST SpaceMobile CEO Abel Avellan sold $146.7 million of stock on June 22. The Walmart Walton family also continued selling, filing disposals worth over $617 million. All three are large but reflect insider confidence in locking in gains near highs.

Analysts Back Micron and Rail Stocks

Micron now has 38 buy ratings and a consensus target of $1,410. Analysts also lifted targets across the US rail sector. Union Pacific, Norfolk Southern, and CSX all moved higher — suggesting growing confidence in freight recovery.
