How the page works

How to read the score

The score shows direction

It describes the weighted balance of qualifying headlines. A score of 50 can mean balanced news or that there is not enough evidence; the status label explains which.

Confidence is separate

Confidence measures depth, source breadth, direct relevance, freshness and agreement. It does not rise merely because the tone is extreme. This is a rule-based evidence measure, not a calibrated probability.

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.

What the page does

It measures news already published. It is not a forecast, recommendation or price target.
