## Overview

StockWise is a browser-based stock-market learning and portfolio demo with illustrative data, not live market services. Users browse the market snapshot and sample stocks, explore companies and maintain a watchlist, track portfolio holdings, read financial learning guides, or create and revisit a demo profile. The React app routes these experiences and shares user, watchlist, and portfolio state through a context provider, persisting that state in browser storage. The graph follows the sampled routing and component code; no backend or external market-data integration is shown.

Main entry points: [`src/App.jsx`](https://github.com/yuvan43/stock-trading-app/blob/main/src/App.jsx) (App Router), [`src/context/AppContext.jsx`](https://github.com/yuvan43/stock-trading-app/blob/main/src/context/AppContext.jsx) (Shared App State), [`src/pages/Companies.jsx`](https://github.com/yuvan43/stock-trading-app/blob/main/src/pages/Companies.jsx) (Company Explorer), [`src/pages/News.jsx`](https://github.com/yuvan43/stock-trading-app/blob/main/src/pages/News.jsx) (Learning Guides)
