On load we pull the latest 50 Finnhub headlines for your top universe symbols (SPY/NVDA/AAPL/TSLA/META/AMZN/MSFT/GOOGL/AMD). For each, we auto-classify the headline (earnings, analyst, M&A, regulatory, macro, etc.) and tag bull/bear sentiment by keyword match. Then we look up the symbol's price at the headline time vs. now and compute reaction R-multiples. Aggregated over time you'll see which headline types you can fade and which follow.
