KO 20-day volatility: the current reading and its track record
KO’s current 20-day volatility reading and what that signal has historically been followed by.
This page covers The Coca-Cola Company (KO) — its current 20-day volatility reading and the measured historical record of what KO 20-day volatility extremes were followed by.
How to read this. These figures are measured only on instruments currently covered by this site — a set of companies that survived. Signals that appear to have ‘worked’ on the downside are conditioned on these names having recovered; a company that fell and never came back would not be here to measure. Read every number below as a property of this surviving sample, not a universal rule, and never as advice.
All figures are ‘excess’ returns — measured relative to each instrument’s own historical drift, not relative to the market. This is not alpha and not a market-beating claim; it isolates the signal from the instrument’s background trend. Measured from the first day each signal appeared (not its most extreme point), so it reflects what was knowable in real time.
Measured across KO’s 20-day volatility history from 1962 to 2024: 27 high-extreme episodes and 103 low-extreme episodes. High-extreme readings were followed by -0.37% excess at 5 sessions and -1.38% by 20; low-extreme readings were followed by +0.04% excess at 5 sessions and -0.10% by 20.
On this signal, the most recent episode in which KO was at a high extreme began on 2020-03-09; the most recent in which it was at a low extreme, on 2024-09-03.
Outcomes are measured for episodes up to 2024-09-03, the most recent with enough later sessions to score. The current reading above is from a later date, 2026-10-16.
