Abstract

Emotions and human behavior are an important subject for academics in the financial field as emotion and mood haven proved by psychologist as a main factor in people behavior and decision-making process. Hence, the modern improvement in social media like Twitter has open new possibilities for exploring more the emotional polarity in human, and their perception toward companies. Does this emotional public sentiment affect people's investment decisions? In this dissertation we explore whether the Nasdaq Composite Index (IXIC) volume is affected by the public mood, using Twitter sentiment analysis and how we can use that information for modelling Nasdaq Composite Volume Change. Our finding prove that sentiment is correlated with change in the IXIC volume, but we can use that information predict change in the IXIC using time series with small dataset.
