GME — Insider Trading Activity

Cluster buy signal. Multiple insiders independently writing personal checks for the same company’s stock is one of the stronger patterns in the Form 4 data — it usually reflects a shared view among people who see the numbers first that the shares are cheap. Historically, 3+ insider clusters have outperformed the broader market over the following 6–12 months. Who is buying. The most credible buyer in this window is the company’s CEO ($50M–$100M), growing their stake by 9%. That insider’s track record: past buys beat the S&P 500 1 of 2 times (avg −2% vs S&P over 6 mo). Overall credibility score: 84/100 (High).

By the numbers. 5 insiders filed 10 open-market purchases at GME over the window, 3,398,897 shares in all at an average of $22.48 a share, most recently on October 2, 2026. On the other side, 2 insiders filed 3 sales covering 18,475 shares at an average of $24.50, the latest on October 5, 2026. That puts the average sale 9% above the average purchase — worth checking against where the stock trades today. Buying over the window ran 14× the dollar value of GME’s trailing 11-month baseline.

How we read these filings — which transaction codes count, how the cluster and credibility thresholds are set, and what the signals have and haven’t predicted — is written up in the insider trading methodology.
