For long-horizon retirement investors, Criteo S.

A. (CRTO) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 76)). Magnite, Inc. (MGNI) carries a higher beta of 1. 63 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (CRTO: -49. 9%, MGNI: -9. 2%), 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 (MGNI (Communication Services) and PUBM (Technology) and DV (Technology) and IAS (Communication Services) and CRTO (Communication Services)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.
