43), 2. 2% yield, +333. 0% 10Y return). Both have compounded well over 10 years (MTG: +333. 0%, MBI: +197. 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.

AGO, AGM, RDN, MTG pay a dividend while MBI does not, making them suitable for different income and tax situations.
