% of all-time high since 1999#
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.
% of all-time high on the price basis — the all-time high considers the full history of MKSI, including years before the visible window. Dividends are excluded on this basis (the convention headlines use).
The deepest drawdowns on record#

Drawdown vs what came next#
One dot per month since 1999: how far MKSI 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: MKSI 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.
