What this means for COO
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 a Director ($1M–$5M), growing their stake by 180%. That insider’s track record: past buys beat the S&P 500 3 of 4 times (avg +8% vs S&P over 6 mo). Overall credibility score: 64/100 (Medium).
By the numbers. 3 insiders filed 5 open-market purchases at COO over the window, 34,701 shares in all at an average of $54.18 a share, most recently on September 16, 2026. No insider sold COO stock on the open market in that period.
