Understanding
Interpreting ZS insider filings
Officers, directors, and 10% owners of ZS must report every trade in their own stock to the SEC within two business days on Form 4. We parse each filing as it lands on EDGAR, so this page is the same primary-source record professionals read, minus the paywall.
The asymmetry that makes this data useful: insiders sell for dozens of innocent reasons (taxes, diversification, a house), but they voluntarily buy on the open market for exactly one reason. That is why buys are headlined and one-off sells deserve little weight.
The strongest historical pattern is the cluster: several different insiders buying within days of each other. A lone director's small buy is noise; the CFO and two directors buying the same week is a documented anomaly worth your attention.
