In this comparison, MKL (2.

7% yield), AIG (2. 2% yield), TRV (1. 4% yield), CB (1. 2% yield) pay a dividend. WTM does not pay a meaningful dividend and should not be held primarily for income.

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

02), 1. 2% yield, +186. 2% 10Y return). Both have compounded well over 10 years (CB: +186. 2%, WTM: +160. 8%), 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.

CB, AIG, MKL, TRV pay a dividend while WTM 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.
