% of all-time high since 1981#
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 GLW, including years before the visible window. Dividends are excluded on this basis (the convention headlines use).
The deepest drawdowns on record#
Every decline of 15% or more from an all-time high (price basis), deepest first.

Price basis (no dividends) — the convention crash histories use. With dividends reinvested, recoveries arrive years earlier; switch the basis on the chart above to see it.
Drawdown vs what came next#
One dot per month since 1981: how far GLW 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: GLW 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.
