KMT — Insider Trading Activity

KMT is not showing a cluster buy or a step-change versus its own baseline, so what the window amounts to is 2 insiders acting separately, with the largest of them accounting for 57% of the dollars. Who is buying. The most credible buyer in this window is the company’s CEO ($100K–$500K), growing their stake by 3%. That insider’s track record: past buys beat the S&P 500 0 of 3 times (avg −3% vs S&P over 6 mo). Overall credibility score: 47/100 (Medium).

By the numbers. 2 insiders filed 2 open-market purchases at KMT over the window, 12,000 shares in all at an average of $29.56 a share, most recently on September 10, 2026. On the other side, 2 insiders filed 2 sales covering 29,676 shares at an average of $30.46, the latest on September 8, 2026. That puts the average sale 3% above the average purchase — worth checking against where the stock trades today.

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.
