ALMS — Insider Trading Activity

ALMS 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 ($10M–$50M), growing their stake by 22%. That insider’s track record: past buys beat the S&P 500 2 of 4 times (avg +81% vs S&P over 6 mo). Overall credibility score: 47/100 (Medium).

By the numbers. One insider filed 4 open-market purchases at ALMS over the window, 986,721 shares in all at an average of $10.87 a share, most recently on September 8, 2026. On the other side, 7 insiders filed 8 sales covering 111,084 shares at an average of $12.68, the latest on September 8, 2026. That puts the average sale 17% 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.
