dc.description.abstractThis thesis investigates whether ESG Score announcements by Thomson Reuters present new information to investors in the Nordic region. The data set consists of 1278 unique events for 309 unique firms publicly noted in either Sweden, Denmark, Norway or Finland in the time period from 2011 to 2020. ESG Score announcements are viewed relative to the score from the previous year, and segmented into positive, negative, and neutral events based on the magnitude of change. Positive events have a year-on-year change of at least 10.61 percent, while negative events have a year-on-year change of less than -2.77 percent. We apply event study methodology and define a test battery consisting of a parametric and a non-parametric test, yielding a test battery robust to flaws in our data set. We found evidence of positive abnormal stock price reactions in days prior to the announcement of both positive and negative events. Therefore, we find evidence that the ESG Score might bring new information to investors. Furthermore, probit regressions are used to examine whether firm characteristics correlate with stock price reactions. We find evidence that smaller firms have a higher likelihood of positive abnormal stock price reactions in days prior to positive and negative events. Moreover, positive events dated 2017 or later, have a higher likelihood of positive stock price reactions in the days prior to the events. The same effect, meaning a positive relationship between the likelihood of positive abnormal price reactions and events dated 2017 or later, is also present for the day prior to negative events.
