TSLA 20-day return: the current reading and its track record
TSLA’s current 20-day return reading and what that signal has historically been followed by.
This page covers Tesla, Inc. (TSLA) — its current 20-day return reading and the measured historical record of what TSLA 20-day return 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 TSLA’s 20-day return history from 2010 to 2026: 22 high-extreme episodes and 36 low-extreme episodes. High-extreme readings were followed by +1.99% excess at 5 sessions and +6.04% by 20; low-extreme readings were followed by -0.21% excess at 5 sessions and -3.69% by 20.
On this signal, the most recent episode in which TSLA was at a high extreme began on 2025-05-15; the most recent in which it was at a low extreme, on 2026-07-28.
Outcomes are measured for episodes up to 2026-07-28, the most recent with enough later sessions to score. The current reading above is from a later date, 2026-10-16.
