One insider at CSPI put personal money into the stock on the open market this window, led by a 10% Owner, with nobody selling.
What this means for CSPI
CSPI 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 10% Owner (< $100K). That insider’s track record: past buys beat the S&P 500 3 of 9 times (avg −15% vs S&P over 6 mo). Overall credibility score: 5/100 (Low).
By the numbers. One insider filed 6 open-market purchases at CSPI over the window, 4,600 shares in all at an average of $7.84 a share, most recently on September 15, 2026. No insider sold CSPI stock on the open market in that period.
