Both have compounded well over 10 years (ABT: +173. 7%, ARAY: -94. 5%), 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.
