Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
Post earnings announcement drift (PEAD) is defined as the drift that occurs in a company’s share priceafter their earnings announcement. A company that reports earnings above (below) the analysts’expectations should, according to previous studies of PEAD, continue to drift upwards (downwards)after the announcement. (Ball & Brown, 1968) The thesis purpose is to investigate if PEAD existed onthe Swedish market between 2006-2010. We test PEAD’s existences through; (i) creating portfolios inwhich companies’ abnormal return (AR) we expect to decline or increase, (ii) doing a multiple regressionanalysis to test if the drift is statistically significant. From the results of our study, we can neither acceptnor reject the hypothesis that PEAD existed on the Swedish market, although the multiple regressionanalysis prove a statistically significant result for companies’ AR that we expect to decline have drifted3,11% in a negative direction compared to our total sample.
