News catalog
Signals derived from news coverage: article volume and sentiment.
| Column | Type | Description |
|---|---|---|
news_volume | numeric | Count of news articles published in the last 24 hours mentioning this ticker with a relevance score ≥ 0.6. Refreshed every 15 minutes. Null when no qualifying articles in the window. |
news_volume_weighted_sentiment | numeric | Range -1.0 to +1.0. The relevance-weighted average sentiment of articles in the last 24 hours, attenuated by `tanh(news_volume / 15)` so quiet tickers (1-2 articles) read near zero regardless of sentiment sign. Strong negative = loud bad news; strong positive = loud good news; values near 0 = quiet or mixed. Null when no qualifying articles. |
