Abstract: We ran a field experiment to investigate whether nudge policies, consisting in behavioural insight messaging, help to improve performance in financial trading. Our experiment involved students enrolled in a financial trading course in an Italian University who were invited to trade on Borsa Italiana’s virtual platform. Students were randomly assigned to a control group and a treatment group. Treated students received a message reminding them of the existence of behavioural biases in financial trading. We find that treated students significantly improve the performance of their portfolio. This effect is mainly driven by students with a higher than average risk aversion. Several behaviours may explain the increase in performance. We find evidence pointing to a reduction in the home and status quo biases for risk averse nudged participants.
