MCD's current 20d return reading and what that signal has historically been followed by.
This page covers McDonald's (MCD) — its current 20d return reading and the measured historical record of what MCD 20d return extremes were followed by.
How to read this. These figures are measured only on instruments currently in our coverage — 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 MCD’s 20d return history from 1966 to 2026: 47 overbought episodes and 45 oversold episodes. Overbought readings were followed by -1.30% excess at 5 sessions and -2.67% by 20; oversold readings were followed by -0.99% excess at 5 sessions and -0.54% by 20.
On this signal, MCD was most recently overbought on 2024-08-21 and most recently oversold on 2026-05-15.
Measured-outcome coverage runs through 2026-05-15 — the most recent episode with forward sessions scored; the current reading above is later, as of 2026-08-21.
