6% yield), TNET (2. 5% yield), TRI (2. 5% yield), BBSI (1. 1% yield) pay a dividend. INSP does not pay a meaningful dividend and should not be held primarily for income.

38), 2. 5% yield, +155. 3% 10Y return). Both have compounded well over 10 years (TRI: +155. 3%, INSP: +82. 4%), 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.
