24), 1. 2% yield, +375. 2% 10Y return). Both have compounded well over 10 years (LIN: +375. 2%, XAIR: -99. 6%), 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.
