We find that investors' risk taking behavior such as portfolio choices can be predicted using risk attitudes, risk perceptions and belief measures such as optimism and overconfidence. However, the predictive power of these determinants heavily depends on the domain in which they were elicited. More specifically, risk attitudes, risk perceptions and beliefs only allow us to predict investors' risk taking behavior if they are elicited in an investment related context. We believe our results could benefit practitioners who could incorporate some of the determinants we have used in their investment advisory process
