Building a Financial Research Agent with ReAct, LangGraph, and LangChain

A full working implementation that autonomously researches any stock - financials, news sentiment, technical indicators - and produces a structured buy/sell brief. I track Indian equities pretty closely. I follow individual names like ICICI, HDFC, Reliance, HAL, etc. And for a while I had this frustrating routine where I’d want to quickly research a ticker before markets opened, and I’d end up spending 40 minutes jumping between Screener.in, Moneycontrol, and random news tabs, manually piecing together a picture. I kept thinking: I build AI systems for a living.
