Cover Story: Accurately forecasting stock price volatility is a critical yet challenging task due to the nonlinear and dynamic nature of financial markets. This study introduces a robust stacking ensemble framework that integrates the strengths of diverse algorithms, including statistical (ARIMA), machine learning (Random Forest), and deep learning (LSTM, GRU, Transformer) models. By employing an XGBoost meta-learner to synthesize these distinct predictions, the proposed model significantly outperforms individual baselines, achieving R2 scores between 0.9735 and 0.9905 across major financial indices. This research demonstrates the efficacy of heterogeneous ensemble learning in navigating market complexities, offering a powerful tool for enhanced financial decision-making. View this paper
