We match company names, explicit ticker tags and cashtags in public WebNovare headlines. A small, versioned keyword model classifies positive and negative phrases; recent headlines receive more weight, with a 48-hour half-life. Repeated headlines count once. Only the last seven days are included.

The 0–100 buy weight maps headline sentiment to an index. It is not a probability, valuation, analyst rating or recommendation. No coverage means no score. News can be wrong, ambiguous or incomplete; inspect the headlines before using a signal. Price feeds, fundamentals and execution checks are separate.
