7% yield), ERIE (2. 2% yield), ASIC (0. 8% yield) pay a dividend. ACGL does not pay a meaningful dividend and should not be held primarily for income.

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

16), 2. 2% yield, +171. 6% 10Y return). Both have compounded well over 10 years (ERIE: +171. 6%, MKL: +89. 3%), 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.
