Aggregate sentiment composite
Education only · our voice · free public data
Definition
A top-level composite that rolls many individual sentiment, positioning, and options indicators into one blended reading, smoothing single-indicator noise into a single crowd-psychology gauge.
How to read it
The aggregate model is the 'index of indices': it combines a broad panel of sentiment inputs into one standardized score so that idiosyncratic noise in any single gauge is averaged out. It is read the same way as its components — contrarily at extremes — but with higher reliability because agreement across many inputs is required to move it to a tail. Practitioners use it as the headline sentiment read and drill into individual models (Optix, smart/dumb, AIM, STEM) to understand what is driving an extreme. Historical-analog framing is common: 'when the aggregate was last this extreme, forward returns tended to...'.
How practitioners use it
Used as context among multiple indicators — never as a standalone signal to act.
Less common professional uses
Averaging cuts both ways: the aggregate lags fast, single-catalyst sentiment shocks that one fast indicator would catch — pair it with a couple of fast gauges. Component crowding: if many inputs share data (e.g., several options-based measures), the composite double-counts one theme — inspect the driver mix before trusting an extreme. A modest aggregate hiding violently divergent components (some euphoric, some fearful) is a mixed-regime warning, not a genuine 'neutral.' Percentile/z-score the aggregate and lean on historical-analog forward-return distributions rather than the raw score.
