## Overview

This repository is a stock-analysis app with a React interface and Flask image API, plus a separate interactive Python analysis script. The web workflow collects a symbol and date range, requests a plot, downloads historical prices, and returns a chart. The standalone script additionally reports statistics, fits and evaluates a linear regression, and plots future predictions. The README is empty; the architecture reflects the supplied tree and sampled source.

Main entry points: [`stock-analysis/stock_analysis.py`](https://github.com/sahniaditya007/stockmarketanalysis/blob/main/stock-analysis/stock_analysis.py) (Historical data and statistics), [`react-app/src/stock.jsx`](https://github.com/sahniaditya007/stockmarketanalysis/blob/main/react-app/src/stock.jsx) (Plot request and display), [`app.py`](https://github.com/sahniaditya007/stockmarketanalysis/blob/main/app.py) (Flask plot handler), [`react-app/src/App.jsx`](https://github.com/sahniaditya007/stockmarketanalysis/blob/main/react-app/src/App.jsx) (Symbol and dates)
