Version AIFI-3 · lagging daily close

Methodology

AIFI publishes a lagging daily close of fear already in public AI coverage. The live product labels the methodology version as AIFI-3. Same inputs under that version replay to the same number.

Daily close

Bands

The UI maps the close into five bands (inclusive lower bound, exclusive upper bound except extreme, which runs through 100):

BandRange

Component family (AIFI-3)

The public close JSON lists weighted components. Labels and relative weights as published in /data/index.json:

On any given day a component may be observed, warming, or missing. Effective weights can shrink when a source is unavailable; coverage metadata in the JSON reports eligible sources and weight. Do not treat a missing component as a fabricated value.

Public machine-readable outputs

Limits. AIFI measures fear already present in public coverage signals. It is not a forecast, not advice, and not a claim about private or proprietary sentiment. Methodology details beyond the public JSON and this page may evolve; the version field identifies the rule set for a given close.
