ALP — Insider Trading Activity

Cluster buy signal. Multiple insiders independently writing personal checks for the same company’s stock is one of the stronger patterns in the Form 4 data — it usually reflects a shared view among people who see the numbers first that the shares are cheap. Historically, 3+ insider clusters have outperformed the broader market over the following 6–12 months. Who is buying. The most credible buyer in this window is a Officer ($100K–$500K), growing their stake by 286%. Overall credibility score: 55/100 (Medium).

By the numbers. 4 insiders filed 11 open-market purchases at ALP over the window, 66,554 shares in all at an average of $4.43 a share, most recently on September 22, 2026. On the other side, one insider filed 1 sale covering 393 shares at an average of $4.15, the latest on September 14, 2026. That puts the average sale 6% below 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.
