Jinx Numbers Effect

Some economy theories assume that human is rational and when they make a decision in uncertainty conditions, they will prefer the best choice. Many evidences have been given against these theories. Especially psychology professor Daniel Kahneman’s studies provide evidence that human behave intuitively rather than rationally. It can be alleged that some superstitions which affect on human psychology such as number 13 fallacy can have an effect on stock exchanges trading behaviors. In this study, number 13 fallacy has been searched for both Romanian and Turkish stock exchanges and not found the anomaly evidence for both stock exchanges. The anomaly has been found for Turkish stock exchange but it is not supported by statistics so, it is a random result.
