The aim of this study is to determine whether political and economic developments have an effect on the current investment decisions of BIST investors. According to the results of the study, H1, H2 and H4 hypotheses, which measure the effect of investment advice, election and presidential debates, and economic and political explanations on investors' investment decisions, were accepted, while H3, H5, hypotheses that measure the variables of self-efficacy and the state of the stock market were rejected. Among these three variables, it was seen that the economic and political explanations (0.432) affected the investment decisions of the investors the most, followed by the election and presidential debates (0.226). It was understood that investment recommendations affected the third place (0.130).
