We conduct a lab-in-the eld experiment to investigate the memory recall bias of real-life investors who are asked to recall their best performing stock (BPS) and worst performing stock (WPS). We have four main ndings. First, investors are more likely to forget WPS than BPS. The proportion of investors who forget WPS and remember BPS is higher than that of those who forget BPS and remember WPS. Second, less experienced investors are more likely to forget WPS than more experienced investors. Third, present biased investors are more likely to forget WPS. Four, investors who pay more attention to stock prices are more likely to forget WPS. Overall, our ndings suggest that investors exhibit motivated memory recall bias.
