AECOM is 56.1% below its all-time high, set Oct 31, 2025 (as of market close, Oct 20, 2026), measured on price alone — dividends are not included, the convention headlines and crash histories use.

% of all-time high since 2007: price#
The classic underwater chart (drawdown curve), drawn as % of the all-time high — 100% is a fresh record, everything below it is time spent underwater. Basis and range are in the URL, so a particular view is a link.
The deepest drawdowns on record#
Every decline of 15% or more from an all-time high (price basis), deepest first.

Drawdown vs what came next#
One dot per month since 2007: how far AECOM stood below its all-time high, and the total return over the following 1, 5 and 10 years.
Read this with survivorship bias in mind: a single asset's history is one surviving sample, so past recoveries here say little about the odds ahead. Monthly windows also overlap heavily (they are not independent samples). Not investment advice.

Methodology & related#
Daily data since -1 from ACM; no free deep history exists for AECOM — for a 150-year drawdown record see the S&P 500 drawdown page. The price basis excludes dividends; the total-return basis reinvests them; the real basis additionally deflates by CPI. See also returns by year. Past performance does not predict future returns; not investment advice.
