This study employs a machine learning-based approach to identify and predict stock market trends using a convolutional neural network (CNN) to the Korean stock market. Building on the methodology introduced in Jiang et al. (2023), we transform historical price and volume data into chart images and utilize CNN to extract patterns predictive of stock returns. Our findings demonstrate that this image-based model can predict the future returns, also in the Korean stock market. Notably, we observe high short-term predictive accuracy, particularly over weekly horizons, which facilitates profitable investment strategies. This study represents the first application of a chart image-based deep learning model to the Korean stock market, contributing new insights into the potential of deep learning techniques in financial market predictability.
