dc.description.abstractIn our thesis, we use event study to analyze relations between Twitter attention and technology companies on the Nasdaq stock exchange. We divide attention into Twitter sentiment and volume. The classification of sentiment is done with supervised machine learning algorithms. The effects of Twitter sentiment are consistent with the Efficient Market Hypothesis. Twitter volume on the other hand, indicates an attention effect related to abnormal market behavior, mainly in larger well-known companies. We believe an indicator as to how individual investors pick stocks, is to distinguish whether a firm’s operations are known to the investors, and how abnormal tweet volume affect traders’ attention towards them.
