One insider at ALK put personal money into the stock on the open market this window, led by the CEO, against 1 insider selling.
What this means for ALK
ALK 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 the company’s CEO ($1M–$5M), growing their stake by 10%. That insider’s track record: past buys beat the S&P 500 0 of 1 time (avg −4% vs S&P over 6 mo). Overall credibility score: 54/100 (Medium).
By the numbers. One insider filed 1 open-market purchase at ALK over the window, 25,000 shares in all at an average of $40.06 a share, most recently on August 20, 2026. On the other side, one insider filed 1 sale covering 5,300 shares at an average of $49.67, the latest on August 3, 2026. That puts the average sale 24% above the average purchase — worth checking against where the stock trades today.
