Why Is AECOM (ACM) Stock Down Today?

AECOM stock closed down 4.26% at $62.22 on August 25, 2026, marking one of the day’s largest declines. The move followed a price target cut by Argus, which lowered its estimate to $75 from $85. The stock opened with a small gap up but quickly reversed direction, reaching a session low of $62.10 before closing near that level.

What Happened

Argus Research, a key analyst covering AECOM, reduced its price target for ACM stock, signaling a shift in its outlook despite maintaining a Buy rating. This adjustment came amid a broader trend of analysts lowering price targets for the company, including RBC Capital, Citigroup, Truist Securities, and Baird. The stock’s intraday performance reflected investor caution, with volume at 0.4 million shares, double the 3-month average, highlighting the significance of the sell-off. Despite the early morning gap up, the stock spent the majority of the session in negative territory, with the low occurring in the afternoon. The stock remains below its 52-week high of $135.52 but above its 52-week low of $60.35.

What The Data Shows

The stock’s fundamentals show a mixed picture. AECOM has a market cap of $8.3 billion and a P/E ratio of 22.8, with trailing twelve-month revenue declining by 4.2%. The company’s net margin is 1.9%, and it offers a dividend yield of 1.91%. The stock’s beta of 0.92 suggests it is slightly less volatile than the broader market. On the 52-week tape, ACM printed 69 fresh 52-week lows on August 25, underscoring the magnitude of the selloff. Recent insider activity includes a purchase by Poloni Lara, AECOM’s president, and several small congressional trades involving Donald J. Trump and Alan Armstrong.
