ASPI — Insider Trading Activity
One insider at ASPI put personal money into the stock on the open market this window, led by a Director, against 3 insiders selling.
What this means for ASPI
ASPI 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), growing their stake by 2%. That insider’s track record: past buys beat the S&P 500 2 of 2 times (avg +51% vs S&P over 6 mo). Overall credibility score: 13/100 (Low).
By the numbers. One insider filed 1 open-market purchase at ASPI over the window, 15,000 shares in all at an average of $2.68 a share, most recently on September 30, 2026. On the other side, 3 insiders filed 6 sales covering 308,391 shares at an average of $3.97, the latest on September 8, 2026. That puts the average sale 48% above the average purchase — worth checking against where the stock trades today.
