Abstract

Stock price forecasting remains a prominent area of research in financial markets due to the complicated, nonlinear, and volatile nature of stock price paths. While high-performance deep learning models like Convolutional Neural Networks (CNN), Long Short-Term Memory (LSTM), and Gated Recurrent Units (GRU) demonstrate superiority in financial forecasting, their comparative efficacy in emerging markets, such as the KSE-100 Index, remains inadequately explored. This study examines the prediction performance of these models based on past stock prices of the KSE-100 Index and based on standard performance measures (root mean square error, mean absolute error, and mean absolute percentage error) to provide a holistic assessment of the models. Our research indicates that GRU consistently performs better than CNN and LSTM, with lower errors and higher predictive accuracy. This work enhances current forecasting methods by utilizing advanced data preparation, feature engineering, and hyperparameter optimization to augment model performance. The results have practical implications for policymakers and investors in emerging markets by emphasizing the applicability of deep learning to financial decision-making.
