The study looked at how investors in the Taiwan stock market tend to be overconfident and make decisions based on emotions rather than logic. By analyzing ten years of data, the researchers found that these investors often hold onto stocks for too long or sell them too quickly, without considering the best timing. This behavior can lead to biased trends in trading volumes and returns. The findings suggest that investors in Taiwan may need to be more cautious and strategic in their decision-making to avoid potential losses.
