% of all-time high on the price basis — the all-time high considers the full history of ASX, including years before the visible window. Dividends are excluded on this basis (the convention headlines use).

Drawdown vs what came next#

Read this with survivorship bias in mind: ASX is on this chart precisely because it survived — the many stocks that fell this far and never recovered (or were delisted) aren't on anyone's chart, 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 closing prices since 2000 (split-adjusted). "All-time" means since our price data begins — ASX may have traded earlier. For a 150-year index 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.
