    total = bullish + bearish
    
    if total == 0:

    neutral = sum(1 for r in results if r["sentiment"] == "neutral")
    avg = sum(r["score"] for r in results) / len(results) if results else 0
    
    return {
        "total": len(headlines),
        "bullish": bullish,
        "bearish": bearish,
        "neutral": neutral,
        "bullish_pct": round(bullish / len(headlines) * 100, 1) if headlines else 0,

Use Cases

  • Pre-market check: Scan overnight news sentiment before trading
  • Position monitoring: Track sentiment changes for held positions
  • Earnings season: Analyze sentiment around earnings reports
  • Contrarian signals: Extreme sentiment (90%+ one direction) often signals reversal
  • Sector rotation: Compare sentiment across sectors to identify rotation

Notes

  • This is keyword-based sentiment analysis, NOT deep NLP
  • Works better with longer texts (headlines + first paragraph)
  • Chinese sentiment keywords need regular maintenance (new slang emerges)
  • Combine with volume/price data for confirmation signals
  • For production, consider finBERT or other pre-trained financial NLP models
