9x versus Quanta Services, Inc. at 113. 2x. On forward P/E, Aecom is actually cheaper at 11. 9x.

In this comparison, ACM (1.

4% yield), FER (0. 4% yield) pay a dividend. PWR, ROAD, STRL do not pay a meaningful dividend and should not be held primarily for income.

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

93), 1. 4% yield, +130. 3% 10Y return). Sterling Infrastructure, Inc. (STRL) carries a higher beta of 3. 06 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (ACM: +130. 3%, STRL: +180. 0%), 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.

Both stocks operate in the Industrials sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: FER is a mid-cap quality compounder stock; PWR is a mid-cap high-growth stock; ROAD is a small-cap high-growth stock; ACM is a small-cap deep-value stock; STRL is a mid-cap high-growth stock. ACM pays a dividend while FER, PWR, ROAD, STRL 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.
