📊 Yahoo Finance Stock Market Analysis (AAPL, MSFT, AMZN, TSLA)

🚀 Introduction

Stock market prediction is a crucial area in financial analysis. Prices of stocks are influenced by various factors, such as market trends, economic indicators, and investor sentiment. This project focuses on analyzing and forecasting stock prices of Apple (AAPL), Microsoft (MSFT), Amazon (AMZN), and Tesla (TSLA) using deep learning.

Using Yahoo Finance data, we apply Exploratory Data Analysis (EDA), Feature Engineering, Preprocessing, and Long Short-Term Memory (LSTM) Regression modeling to predict stock prices.

🎯 Objectives

✅ Retrieve stock market data using yfinance 📈
✅ Perform EDA to visualize trends & correlations 📊
✅ Extracting features like RSI, MACD,Bollinger Bands, Moving Averages vs.
✅ Preprocess the data for deep learning (normalization, handling missing values)
✅ Implement an LSTM and Linear Regression models for stock price forecasting 🧠
✅ Evaluate predictions using RMSE, and MAE scores
✅ Compare actual vs. predicted stock prices 📉

🏗️ LSTM Model Architecture

The BiLSTM (Bidirectional Long Short-Term Memory) model used for stock price prediction follows the architecture below:

Model Overview

• Input Shape: (n_timesteps, 18)
  The input consists of sequences with n_timesteps (time steps) and 18 features for each time step.

• LSTM Layers:

  • 3 stacked Bidirectional LSTM layers with 64 units each.
    The bidirectional nature allows the model to learn from both past and future data points.

• Fully Connected Layer (Dense Layer):
  A Dense layer with 32 units and ReLU activation to learn complex patterns from the LSTM outputs.

• Output Layer:
  A final Dense layer with 1 unit to predict the 'Close' price of the stock.

Model Parameters

• Activation Function:

  • Hidden layers: ReLU activation
  • Output layer: Linear activation

• Optimizer:
  Adam optimizer for efficient training and learning.

• Loss Function:
  Huber loss for robust training, balancing between Mean Squared Error (MSE) and Mean Absolute Error (MAE).

This architecture is designed to effectively capture complex patterns in time-series data, particularly for stock price forecasting.

📈 Results & Evaluation

The model is evaluated using the following metrics:

📌 Root Mean Square Error (RMSE)
📌 Mean Absolute Error (MAE)

📌 Future Improvements

🔹 Hyperparameter Optimization: We will fine-tune model parameters to enhance predictive accuracy and reduce errors.

🔹 Model Comparison: In addition to LSTM, we will evaluate and compare performance with ARIMA, XGBoost, and CNN models to identify the most effective approach.

🔹 Feature Expansion: We plan to incorporate additional financial indicators and external factors (e.g., market sentiment, economic trends) to improve model robustness.

🔹 Hybrid Model Approach: Combining LSTM with ARIMA, XGBoost, and CNN to leverage both deep learning and traditional statistical methods for improved performance.
