4x versus Quanta Services, Inc. at 110. 4x. On forward P/E, Aecom is actually cheaper at 13. 6x.

In this comparison, ACM (1.

2% yield), VMC (0. 7% yield), GVA (0. 3% yield), PRIM (0. 3% yield) pay a dividend. PWR does not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Vulcan Materials Company (VMC) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0.

81), 0. 7% yield, +158. 0% 10Y return). Both have compounded well over 10 years (VMC: +158. 0%, PWR: +31. 2%), 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 (GVA (Industrials) and PRIM (Industrials) and PWR (Industrials) and VMC (Basic Materials) and ACM (Industrials)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: GVA is a small-cap quality compounder stock; PRIM is a small-cap high-growth stock; PWR is a mid-cap high-growth stock; VMC is a mid-cap quality compounder stock; ACM is a mid-cap quality compounder stock. VMC, ACM pay a dividend while GVA, PRIM, PWR do not, making them suitable for different income and tax situations. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
