Abstract

Value investing relies on identifying stocks with strong financial fundamentals and long-term growth potential. However, with the increasing volume and complexity of financial data, traditional stock classification methods may struggle to efficiently differentiate stocks based on their intrinsic value. To address this challenge, this paper presents a stock classification approach for value investing by leveraging Principal Component Analysis (PCA) and K-means clustering. Dimensionality reduction and the extraction of crucial financial factors influencing stock performance are achieved through the use of PCA, while K-means clustering categorizes stocks based on their financial characteristics. By analyzing stock index data from the A-share market over the past four years, the study identifies meaningful financial patterns and classifies stocks into distinct groups. The results demonstrate that the classification remains stable across multiple years, providing investors with a structured method to differentiate stocks based on their financial attributes. This classification approach can serve as a reference for value investors, aiding in portfolio construction and risk assessment.
