Portfolio risk management has become increasingly challenging due to the growing complexity and volatility of modern financial markets. This study proposes a predictive portfolio risk optimization framework utilizing advanced statistical learning techniques to enhance risk forecasting and investment decision-making. The research integrates machine learning models, including Random Forest Regression, Gradient Boosting Machines, Support Vector Regression, and Elastic Net Regression, with portfolio optimization methodologies to improve asset allocation strategies. A hypothetical dataset comprising historical market data, asset returns, volatility measures, and macroeconomic indicators was employed to evaluate model performance. The results demonstrate that advanced statistical learning models significantly outperform traditional regression-based approaches in predicting portfolio risk. Among the evaluated models, the Gradient Boosting Machine achieved the highest predictive accuracy, leading to superior portfolio optimization outcomes. The machine learning-enhanced portfolio exhibited higher annualized returns, lower volatility, improved risk-adjusted performance, and reduced maximum drawdowns compared with conventional portfolio optimization methods. The findings suggest that integrating predictive analytics and statistical learning into portfolio management can strengthen risk control, improve investment efficiency, and support more resilient financial decision-making. This framework provides valuable insights for portfolio managers, financial analysts, and institutional investors seeking data-driven approaches to optimize portfolio performance under dynamic market conditions.
