ASND — Insider Trading Activity

ASND 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 22%. That insider’s track record: past buys beat the S&P 500 3 of 6 times (avg −2% vs S&P over 6 mo). Overall credibility score: 30/100 (Low).

By the numbers. One insider filed 2 open-market purchases at ASND over the window, 2,000 shares in all at an average of $246.33 a share, most recently on August 14, 2026. On the other side, 2 insiders filed 2 sales covering 3,236 shares at an average of $269.75, the latest on September 8, 2026. That puts the average sale 10% 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.
