Health Information Services sentiment intelligence

The score measures the polarity of qualified published news after relevance, source quality, event importance and freshness weighting. It is centred at 50.

Breadth measures how widely constructive or cautious classifications are shared. A few extreme equities cannot create broad participation.

Confidence measures sample depth, direct-company coverage, publisher diversity, freshness and agreement. It is intentionally separate from direction.

Completed weekly price data tests whether the market confirms, rejects or absorbs the narrative. Price never feeds back into the sentiment score.

Unqualified ticker records are excluded, and subgroup maps require at least five qualified securities. Thin slices are disclosed instead of ranked.

This is a current evidence classification, not a forecast, target, recommendation or measure of investor positioning.
