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 AMZN’s RSI(14) history from 1997 to 2026: 84 overbought episodes and 45 oversold episodes. Overbought readings were followed by -0.24% excess at 5 sessions and -1.64% by 20; oversold readings were followed by +1.79% excess at 5 sessions and +0.56% by 20.
On this signal, AMZN was most recently overbought on 2026-08-03 and most recently oversold on 2026-02-06.
Measured-outcome coverage runs through 2026-08-03 — the most recent episode with forward sessions scored; the current reading above is later, as of 2026-08-21.

How AMZN RSI(14) is measured
RSI(14) is the 14-day Relative Strength Index, a momentum gauge bounded between 0 and 100, computed from AMZN’s daily closing prices using Wilder’s smoothing. On this page a reading of 70 or above is treated as overbought and 30 or below as oversold; each historical episode is counted from the first session the threshold was reached (not its most extreme point).
Forward results are measured as excess versus AMZN’s own trailing drift, not versus the market. This page reports the readings and what historically followed them; it does not interpret any level as a signal to buy or sell. See the methodology & reproducibility notes for the full calculation and sample rules.
