Abstract -- The stock market is inherently volatile and influenced by a wide array of factors including economic indicators, political events, market sentiment, and company-specific news. Accurately predicting stock prices has long been a challenge for investors, traders, and researchers alike. This project, titled "Stock Market Prediction", aims to leverage advanced machine learning techniques to forecast future stock prices based on historical data and key market indicators.
The study employs a combination of supervised learning algorithms such as Linear Regression, Support Vector Machines (SVM), and ensemble methods like Random Forest, as well as deep learning models including Long Short-Term Memory (LSTM) neural networks. These models are trained on historical stock price data, technical indicators (such as moving averages, RSI, MACD), and, optionally, sentiment analysis from financial news and social media. Feature selection and data preprocessing techniques such as normalization, data smoothing, and time-series windowing are applied to enhance model accuracy and stability.
Evaluation metrics such as Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and R² score are used to assess model performance. Among the approaches tested, LSTM models demonstrate superior accuracy in capturing temporal dependencies and nonlinear trends in stock price movements. The system also includes a user-friendly interface that allows users to input stock ticker symbols and receive predictive insights and visualizations of expected price trends.
This project not only highlights the potential of AI in financial forecasting but also underscores the limitations posed by market unpredictability, overfitting risks, and external variables that cannot be quantified easily. The findings contribute to the growing field of algorithmic trading and financial analytics, offering a practical tool for decision-makers and investors.
