Both have compounded well over 10 years (IAS: -49. 8%, CDLX: -94. 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 (CDLX (Communication Services) and IAS (Communication Services) and DV (Technology) and MGNI (Communication Services)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: CDLX is a small-cap quality compounder stock; IAS is a small-cap quality compounder stock; DV is a small-cap quality compounder stock; MGNI is a small-cap deep-value stock. 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.
