6% yield), LDOS (1. 2% yield) pay a dividend. STAI, CODA, TDY do not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Science Applications International Corporation (SAIC) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0.

27), 1. 6% yield, +104. 0% 10Y return). Both have compounded well over 10 years (SAIC: +104. 0%, STAI: -99. 2%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.

These companies operate in different sectors (STAI (Basic Materials) and CODA (Industrials) and SAIC (Technology) and TDY (Technology) and LDOS (Technology)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: STAI is a small-cap quality compounder stock; CODA is a small-cap high-growth stock; SAIC is a small-cap deep-value stock; TDY is a mid-cap quality compounder stock; LDOS is a mid-cap deep-value stock. SAIC, LDOS pay a dividend while STAI, CODA, TDY do not, making them suitable for different income and tax situations.
