This dissertation examines the influence of mass media, as well as social media, on investor behavior and financial market fluctuations. The main goal is to understand the mechanisms through which information and psychology influence investment decisions. In order to meet this objective, methodologically, a critical review of the international literature was conducted. In this context, emphasis was placed on the fundamental principles of economic and financial behavior, the contribution of behavioral finance, the role of traditional mass media, as well as the power of social media as sources of financial information. The conclusions, that had been emerged from this literature review, showed that markets, do not operate exclusively and solely on the basis of rational models. On the contrary, they are influenced by psychological and communication factors. Among these, social media have the tendency to accelerate the spread of both valid information and misinformation, as well. This dissertation, finally, concludes that understanding investment behavior, especially in the current digital era, requires an interdisciplinary approach. For this reason, it was proposed to strengthen financial literacy, the use of sentiment analysis tools and the development of regulatory frameworks for the more effective management of misinformation.
