Insiders Dump Big at Nvidia and Tutor Perini

Two major insider sell-offs hit the tape this week, with filings disclosing hundreds of millions in stock sales across very different companies.

At NVDA, director Mark Stevens filed on September 2 disclosing he sold roughly $342M worth of shares. The trades took place August 31 through September 2, covering 1.55 million shares at prices around $220. General Counsel Timothy Teter also filed the same day, disclosing a further $6.5M in sales. Stevens is an independent director, not a company operator — but the sheer scale stands out. Nvidia carries a $5.5 trillion market cap and short interest of just 1.2% of free float.

At TPC, Executive Chairman Ronald Tutor filed on September 2 disclosing he sold 1.5 million shares on August 31 for $128M, followed by a separate 800,000-share sale worth $68M — a combined $197M out the door in a single day. Two independent directors also sold earlier in August. Tutor Perini's market cap sits at $4.6B, making this a concentrated exit by the company's founder and chairman.

Separately, an AAPL buzz angle is circulating: at least one congressman who bought over $1M in Apple stock reportedly holds firm despite CEO Tim Cook's exit. Apple SVP Jennifer Newstead has filed routine weekly sales of around 1,400 shares each — small, recurring, and low-signal.
