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 BRK-B’s RSI(14) history from 1996 to 2026: 79 overbought episodes and 42 oversold episodes. Overbought readings were followed by -0.35% excess at 5 sessions and -0.30% by 20; oversold readings were followed by +0.70% excess at 5 sessions and +1.38% by 20.

On this signal, the most recent episode in which BRK-B was overbought began on 2026-10-14; the most recent in which it was oversold, on 2026-03-27.

Outcomes are measured for episodes up to 2026-10-14, the most recent with enough later sessions to score. The current reading above is from a later date, 2026-10-16.

How BRK-B RSI(14) is measured

RSI(14) is the 14-day Relative Strength Index, a momentum gauge bounded between 0 and 100, computed from BRK-B’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 BRK-B’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 and reproducibility notes for the full calculation and sample rules.
