UMBF — Insider Trading Activity

UMBF 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 59% of the dollars. Who is buying. The most credible buyer in this window is a Director (< $100K), growing their stake by 1%. That insider’s track record: past buys beat the S&P 500 7 of 9 times (avg +5% vs S&P over 6 mo). Overall credibility score: 26/100 (Low).

By the numbers. 2 insiders filed 2 open-market purchases at UMBF over the window, 967 shares in all at an average of $139.60 a share, most recently on September 1, 2026. On the other side, 10 insiders filed 13 sales covering 37,402 shares at an average of $148.64, the latest on August 17, 2026. That puts the average sale 6% 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.
