Abstract

The study aims to empirically evaluate the effectiveness of big data in aiding investors with their decision-making. Our findings indicate that big data funds do not exhibit superior performance compared to their human-managed counterparts. The big data factor utilized in the investment strategies of big data funds does not enhance their stock-selection ability. Additionally, the performance of big data funds is not more persistent than that of traditional funds and is significantly influenced by fund managers’ skills, which shows that big data technology and AI algorithms can not replace fund managers in decisions. Overall, these findings suggest that, thus far, big data technology has not yielded significant improvements in fund performance.
