In this comparison, ERIE (2.

2% yield), MMC (1. 8% yield), AON (0. 9% yield), RYAN (0. 7% yield) pay a dividend. ACGL does not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Aon plc (AON) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0.

10), 0. 9% yield, +219. 8% 10Y return). Both have compounded well over 10 years (AON: +219. 8%, ACGL: +324. 0%), 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.

Both stocks operate in the Financial Services sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: RYAN is a small-cap high-growth stock; ACGL is a mid-cap deep-value stock; ERIE is a mid-cap quality compounder stock; AON is a mid-cap quality compounder stock; MMC is a mid-cap quality compounder stock. RYAN, ERIE, AON, MMC pay a dividend while ACGL does 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.
