Adaptive Kalman Filtering for High-Frequency Stock Forecasting

Abstract

Adaptive Kalman filtering techniques are used to demonstrate significant improvements in forecasting accuracy within high-frequency financial time series. This study presents a comprehensive comparative evaluation of four Extended Kalman Filter (EKF) variants—Standard EKF, Adaptive-R EKF, Forgetting Factor EKF, and Mahalanobis Distance EKF—for modeling and forecasting high-frequency stock prices. Utilizing real 1-minute interval data from GARAN, a major Turkish banking stock, we adopt a physically inspired three-dimensional state vector comprising price, velocity, and acceleration to capture nuanced market dynamics. Our methodology systematically incorporates adaptive mechanisms to handle time-varying measurement noise and anomalous observations. The performance of each EKF variant is assessed using four standard metrics: Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and Coefficient of Determination (R²). Among the evaluated filters, the Adaptive-R EKF demonstrates superior prediction accuracy while maintaining interpretable and robust state estimates. This work contributes to the financial signal processing literature by integrating second-order market dynamics into recursive filtering architectures and highlighting the practical benefits of adaptive noise modeling in high-frequency settings.
