90), 4. 2% yield). Fox Factory Holding Corp.

Both have compounded well over 10 years (LKQ: +4. 2%, FOXF: +2. 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.
