  2. 1. Information and financial markets

    Author : Stefan Anchev; Jörgen Hellström; Rickard Olsson; Juha-Pekka Kallunki; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information; dissemination of information; production of private information; information disadvantage; investor base; stock return anomalies; stock price informativeness; quantity of firm disclosure; less sophisticated individual investors;

    Abstract : The results in this thesis are consistent with the hypotheses that: 1) the incomplete dissemination of information across investors helps in explaining the occurrence and the persistence of cross-sectional stock return anomalies, 2) the properties of the investor base of a stock have implications for the informativeness of the stock's price and 3) a greater quantity of firm disclosure places less sophisticated investors at an information disadvantage. Overall, the thesis provides new empirical evidence about the role of information in financial markets. READ MORE
