GameStop’s CEO Is Buying—Here’s Who’s Joining Him

Today's Top Insider Moves That Matter

Tech cracked. Utilities buckled. Healthcare limped. If you were hiding in defensive names, Monday hit like a wake-up call. Consumer electronics and pharma saw sharp pullbacks, while insurers and builders weren’t spared either. But it wasn’t all doom—semiconductors surged, internet retail rebounded, and parts of industrials quietly outperformed.

Insiders? They moved fast. Executives in high-flying tech trimmed exposure, while heavy-hitters in credit, oil, and real estate made bold buys. Cluster activity spiked in niche sectors and beaten-down names—signals that smart money might be repositioning while the crowd reacts.

Let’s break it down.

Biggest Insider Sales

🚂 Westinghouse Air Brake Technologies $WAB ( ▼ 0.73% ) – CEO Dumps $9.8M Worth of Shares

• Who’s Selling? Rafael Santana (President & CEO)

• What They Sold: 55,942 shares at $175.74

• Total Value: $9.8M

• Why It Matters: A 28% ownership reduction is more than a trim—it’s a signal. With WAB’s stock up sharply this quarter, this sale could mark a top or just prudent timing.

🥣 Kellanova $K ( ▼ 0.18% ) – Foundation Trust Quietly Offloads $9.4M

• Who’s Selling? Kellogg W K Foundation Trust (10% Owner)

• What They Sold: 114,583 shares at $82.03

• Total Value: $9.4M

• Why It Matters: The trust still holds over 47 million shares, but this consistent unloading raises eyebrows. Is K due for a valuation reset?

🧬 Tectonic Therapeutic $TECX ( ▼ 5.76% ) – Director Slashes Stake by 43%

• Who’s Selling? Terrance McGuire (Director)

• What They Sold: 500,000 shares at $17.10

• Total Value: $8.6M

• Why It Matters: That’s nearly half his holdings gone in one trade. When biotech board members cash out this aggressively, it’s worth watching.

🌨️ Snowflake $SNOW ( ▼ 0.16% ) – Director Nets $6.6M While Shares Stay Icy

• Who’s Selling? Michael Speiser (Director)

• What They Sold: 50,741 shares at $129.25

• Total Value: $6.6M

• Why It Matters: Speiser’s still sitting on 2.4M shares, but this sale follows a string of insider moves. Tech names like SNOW could be facing resistance.

💼 Paychex $PAYX ( ▼ 0.69% ) – SVP Unloads Over Half His Stake

• Who’s Selling? Michael Gioja (SVP)

• What They Sold: 31,653 shares at $154.59

• Total Value: $4.9M

• Why It Matters: With a 57% drop in ownership, this isn't subtle. Whether it's tax planning or tactical, insiders don’t slash stakes like this without reason.

The week’s sales are pointing to profit-taking in both high-flying tech and stable dividend names. But not everyone’s heading for the exits...
