Source headlines

The news behind the score

No matched evidence

Every row shows the public evidence used to understand the read. Direct company stories carry more weight than industry or sector context; duplicate coverage is consolidated before scoring.

No qualifying company evidence

The system found no fresh, sufficiently relevant headline to place in the evidence ledger. It does not infer a neutral outlook from missing coverage.

How the page works

How to read the score

Tone is directional

It describes the weighted balance of qualifying headlines. A score of 50 can mean a balanced tape or that direction has been withheld for insufficient evidence; the status label distinguishes them.

Confidence is separate

Confidence measures depth, source breadth, direct relevance, freshness and agreement. It does not rise merely because the tone is extreme.

Price is confirmation

Weekly price response, trend and fair-value position test whether the market is accepting or rejecting the news. They never rewrite the news score.

Classification, not prediction

The page describes completed evidence available at the stated time. It is research context, not a forecast, recommendation, target or execution instruction.
