Given the increasing importance of mutual funds as an investment vehicle in Türkiye, this study explores the effectiveness of a state-of-the-art machine learning approach. Utilizing historical data from TEFAS, the LightGBM model is employed to capture complex patterns and non-linear relationships within the financial time series data. The research outlines the methodology for data preparation, feature implementation, data splitting, model configuration, training, and evaluation, including case studies to demonstrate the practical application and results}, number={4}, publisher={Karyay Karadeniz Yayımcılık Ve Organizasyon Ticaret Limited Şirketi}
