Both have compounded well over 10 years (TFII: +713. 0%, COHU: +348. 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.

These companies operate in different sectors (ASX (Technology) and AMKR (Technology) and TFII (Industrials) and ONTO (Technology) and COHU (Technology)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.
