% Showing Excess Optimism / Pessimism
Education only · our voice · free public data
Definition
A breadth-of-sentiment measure: the percentage of tracked indicators currently registering excess (extreme) optimism or excess pessimism. It gauges how widespread a sentiment extreme is across the whole indicator panel.
How to read it
Rather than reading any single sentiment model, this measure counts how many indicators across the panel have crossed into their extreme zones. A high '% showing excess optimism' means the extreme is broad-based — many independent gauges agree the crowd is euphoric — which carries more weight than one indicator alone. Symmetrically, a high '% showing excess pessimism' signals widespread capitulation. Breadth of agreement is the point: isolated extremes are noise, but a large fraction of the panel lining up marks a durable, high-conviction sentiment condition read contrarily.
How practitioners use it
Used as context among multiple indicators — never as a standalone signal to act.
Less common professional uses
Breadth-of-sentiment turns are powerful: watch the % rolling down from a euphoria peak — the crowd of indicators de-escalating together is a stronger reversal cue than any one gauge. A rising % into a price advance while the index still climbs is a distribution warning (many gauges getting extreme beneath a still-rising tape). Correlation caveat: some panel indicators share inputs, so the count overstates independence — weight distinct data families more heavily. Percentile-frame the % itself; 'high' is relative to how broad extremes have historically become in each regime.
