Stock Hub blends real-time market data with AI in ways most trackers skip. Every stock gets an AI Briefing (bull/bear case, key drivers, valuation) plus a two-stage DCF fair-value estimate in Key Statistics. Portfolios get an AI Portfolio Analyst; news gets an AI Market Digest with sentiment scoring. A built-in Politicians tab tracks congressional stock trades. Multi-portfolio tracking, a screener, and an economic calendar round it out — no brokerage account required.
