ZS — Insider Trading Activity
4 insiders sold outside 10b5-1 plans in 30 days at ZS, outside any pre-arranged Rule 10b5-1 plan, and not alone.
What this means for ZS
ZS is not showing a cluster buy or a step-change versus its own baseline, so what the window amounts to is selling only. Unusual selling. 4 insiders sold outside 10b5-1 plans in 30 days; CFO sold 12% of their stake, and more than one insider sold inside the same window. None of it was executed under a pre-arranged Rule 10b5-1 plan, so the timing was the insider’s own choice — $1M–$5M of discretionary selling in total.
By the numbers. No insider at ZS filed an open-market purchase in the last 90 days. On the other side, 6 insiders filed 31 sales covering 33,161 shares at an average of $193.06, the latest on September 25, 2026.
