📈 Stock Analysis using MATLAB (ARIMA & LSTM)

This project applies time series forecasting techniques (ARIMA and LSTM models) to predict stock market prices using MATLAB.
It demonstrates how classical statistical methods and modern deep learning approaches compare in financial prediction tasks.

🚀 Features

• ARIMA Model

  • Captures linear trends & seasonality.
  • Useful for short-term forecasting.

• LSTM Model

  • Recurrent neural network specialized for sequential data.
  • Captures long-term dependencies in stock prices.
  • Outperforms ARIMA for highly volatile data.

• Comparison of Results

  • Forecast accuracy measured using RMSE & MAPE.
  • Graphical comparison of predicted vs. actual stock prices.

📊 Dataset

You can download historical stock price data from the NASDAQ website:
👉 NASDAQ Historical Data

Example:

1. Search for a ticker symbol (e.g., AAPL for Apple, TSLA for Tesla).
2. Go to the “Historical Data” tab.
3. Select the time period (e.g., 5 years).
4. Click Download (CSV file).
5. Place the CSV file in the data/ folder.
