For long-horizon retirement investors, American Water Works Company, Inc.

(AWK) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β -0. 48), 2. 6% yield, +100. 9% 10Y return). Energy Recovery, Inc. (ERII) carries a higher beta of 1. 53 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (AWK: +100. 9%, ERII: -11. 9%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

These companies operate in different sectors (ERII (Industrials) and FELE (Industrials) and PNR (Industrials) and XYL (Industrials) and AWK (Utilities)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.
