What this means for CINF
CINF is not showing a cluster buy or a step-change versus its own baseline, so what the window amounts to is a single insider acting alone. Who is buying. The most credible buyer in this window is a Director ($100K–$500K), growing their stake by 2%. That insider’s track record: past buys beat the S&P 500 2 of 6 times (avg +0% vs S&P over 6 mo). Overall credibility score: 19/100 (Low).
By the numbers. One insider filed 1 open-market purchase at CINF over the window, 1,000 shares in all at an average of $171.64 a share, most recently on August 25, 2026. On the other side, one insider filed 1 sale covering 7,600 shares at an average of $175.40, the latest on August 3, 2026.
