2. Overall sentiment analysis summary, including:
   • General sentiment (Very Bearish, Bearish, Neutral, Bullish, Very Bullish)
   • Total number of articles analyzed
   • Average confidence score
   • Sentiment distribution
   • Weighted sentiment score

Caching

The script uses a caching mechanism to store sentiment analysis results. This helps to:

• Reduce API calls to OpenAI
• Speed up subsequent runs on the same topic
• Allow for offline analysis of previously fetched articles

Cache files are stored in the cache directory with filenames based on the analyzed topic.
