Investment Agent Swarm
The client wanted 4 AI analysts debating the same stock in real-time. I built the boardroom.
Multi-agent investment analysis platform where 4 specialized AI agents collaborate to provide comprehensive stock analysis across US and Korean markets.
The Backstory
The brief was ambitious: build a virtual boardroom where 4 AI analysts — a macro economist, a fundamental analyst, a chart technician, and a sentiment reader — all look at the same stock and debate their views in real-time. Then a consensus engine synthesizes everything into a unified investment thesis with a confidence score.
I went beyond the brief: added mock trading with P&L tracking, TradingView-quality charts, daily AI briefings with text-to-speech, cross-market Korea-US correlation analysis, and watchlists with condition-based alerts. The result is less “stock screener” and more “AI investment team in your browser.”
