(RS) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 76), 1. 3% yield, +463. 9% 10Y return). Both have compounded well over 10 years (RS: +463. 9%, FSTR: +273. 1%), 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.
