COSM — Insider Trading Activity
One insider at COSM put personal money into the stock on the open market this window, led by the CEO, with nobody selling.
What this means for COSM
COSM 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 ($100K–$500K), growing their stake by 8%. That insider’s track record: past buys beat the S&P 500 4 of 10 times (avg −4% vs S&P over 6 mo). Overall credibility score: 40/100 (Medium).
By the numbers. One insider filed 2 open-market purchases at COSM over the window, 1,116,109 shares in all at an average of $0.19 a share, most recently on July 30, 2026. No insider sold COSM stock on the open market in that period.
