9% yield), IPG (5. 4% yield), OMC (3. 5% yield) pay a dividend. HYFM, GRWG do not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Omnicom Group Inc.

(OMC) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 58), 3. 5% yield). Both have compounded well over 10 years (OMC: +23. 7%, GRWG: -75. 7%), 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 (OMC (Communication Services) and HYFM (Industrials) and IPG (Communication Services) and GRWG (Consumer Cyclical) and WPP (Communication Services)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: OMC is a mid-cap income-oriented stock; HYFM is a small-cap quality compounder stock; IPG is a small-cap deep-value stock; GRWG is a small-cap quality compounder stock; WPP is a small-cap deep-value stock. OMC, IPG, WPP pay a dividend while HYFM, GRWG do not, making them suitable for different income and tax situations. 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.
