This study investigates the influence of fund managers' stock trading ability, fund management ability, and tenure on investor preferences for equity mutual funds. It aims to identify exceptional fund managers and explore company-related factors such as fund size, number of funds managed, employed managers, and establishment duration. The research analyzes the annualized return to assess stock trading ability and the number of funds managed to evaluate fund management ability. The study comprehensively examines the impact of these variables on investor preferences and aims to develop decision-making patterns among mutual fund investors to inform management policies. Drawing on management science perspectives and quantitative tools, the research delves into fund company management methods and personal knowledge management. The anticipated outcome is the presentation of a robust model that will provide valuable insights for fund managers, regulators, and the government, contributing to the efficiency and development of the asset management industry and the advancement of China's economy. Among the seven variables analyzed, six were found to have a positive impact on market preference, except for the number of funds managed by the company, which had a negative influence. This suggests that an excessive number of funds managed by a company may raise concerns among investors regarding the company's ability to effectively manage such a large portfolio. By developing an enhanced full-chain management model for Chinese mutual funds, the study provides valuable insights into fund investor decision-making, leading to improvements in the mutual fund management process, regulatory practices, and investor protection.
