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.

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.
