CORZ — Insider Trading Activity

CORZ 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 68% of the dollars coming from one of them. Who is buying. The most credible buyer in this window is a Director ($100K–$500K), growing their stake by 5%. That insider’s track record: past buys beat the S&P 500 2 of 3 times (avg +21% vs S&P over 6 mo). Overall credibility score: 35/100 (Low).

By the numbers. 2 insiders filed 3 open-market purchases at CORZ over the window, 19,000 shares in all at an average of $18.02 a share, most recently on September 15, 2026. On the other side, one insider filed 16 sales covering 110,000 shares at an average of $19.07, the latest on October 5, 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.
