A research team from Sejong University has discovered that retail investors' heightened attention towards specific stocks often leads to reduced returns for those stocks in the future. The study, published in the esteemed Journal of International Financial Markets, Institutions & Money in the past month, was spearheaded by Professor Lee Eun-mi from the College of Business and Economics, along with doctoral students Yang Pujian and Yang Liu.
The paper, titled "The Retreat of Arbitrage Capital: Attention Level and Nonlinear Order Flow Dynamics," lists Yang Pujian as the primary author, with Lee and Liu as co-authors. The researchers delved into the impact of retail investor attention on the actions of institutional traders and overall stock market returns. The study analyzed data from China's A-share market, which covered the period from 2012 to 2024.
They utilized the Search Volume Index (SVI) provided by Baidu, China's leading search engine, to gauge investor attention. The findings revealed that stocks which capture more attention from retail investors tend to yield comparatively lower returns over time.
