Natural Language Processing (NLP) is becoming the secret weapon of traders using AI. By analyzing public sentiment from news articles, earnings calls, Reddit threads, and tweets, AI models can spot market-moving emotions before prices react.

What is Sentiment Analysis?

Sentiment analysis categorizes text as positive, negative, or neutral. More advanced models also detect emotion, sarcasm, and intent.

Tools and Sources

• Twitter sentiment for meme stocks


• News scraping for earnings surprise signals


• Reddit for crowd psychology


• Transcripts of CEO commentary

Trading Applications

• Forecasting stock movements


• Adjusting portfolio risk dynamically


• Market timing based on social buzz
