For long-horizon retirement investors, Zscaler, Inc.

(ZS) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 98), +363. 0% 10Y return). Both have compounded well over 10 years (ZS: +363. 0%, IOT: +21. 9%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.

These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
