<dim:field mdschema="dc" element="description" qualifier="abstract" lang="is">Í þessari ritgerð er kannað hvort fréttatilkynningar Ölgerðarinnar Egils Skallagrímssonar hf. til Kauphallarinnar hafi marktæk áhrif á verðmyndun hlutabréfaverðs félagsins til skamms tíma. Notast var við aðferðafræði atburðarannsókna (e. event studies) þar sem umframávöxtun í kringum birtingu opinberra frétta voru greindar og bornar saman við kenningu Fama (1970) um skilvirkni markaða (e. efficient market hypothesis). Í greiningunni voru teknir fyrir 43 atburðir og þeir flokkaðir sem jákvæðir, neikvæðir eða hlutlausir. Niðurstöður benda til þess að jákvæðar og neikvæðar fréttir sýni fram á marktæk viðbrögð í kringum birtingu frétta, meðan hlutlausar fréttir hafi almennt ekki áhrif á umframávöxtun. Þetta styður kenningu Fama um meðal sterka skilvirkni markaðarins þar sem opinberar upplýsingar endurspeglast hratt í verði. Takmarkanir rannsóknarinnar felast meðal annars í fáum atburðum, lágu skýringarhlutfalli (R2) milli félags og vísitölu ásamt mögulegri skekkju vegna viðskiptatíðni félagsins á markaði. Ritgerðin veitir ákveðna hugmynd um hegðun fjárfesta á íslenskum hlutabréfamarkaði og viðbrögð þeirra við nýjum upplýsingum.</dim:field>
<dim:field mdschema="dc" element="description" qualifier="abstract" lang="en">This thesis examines whether official company announcements from Ölgerðin Egill Skallagrímsson hf. to the Nasdaq Iceland stock exchange have a statistically significant short-term impact on the company’s stock price. The event study methodology was applied to analyze abnormal returns surrounding the publication of public news, in reference to Fama’s (1970)&#xd;
Efficient Market Hypothesis.&#xd;
A total of 43 events were analyzed and categorized as positive, negative or neutral. The results indicate that positive and negative announcements show significant market reactions around the time of publication, while neutral announcements generally had no effect on abnormal returns. These findings support Fama’s (1970) semi-strong form of market efficiency, suggesting that public information is rapidly reflected in stock prices.&#xd;
The main limitations of the study include the relatively small number of events, low explanatory power between the stock and market index and potential bias due to the company's trading frequency. The thesis offers insights into investor behavior on the Icelandic stock market and their responses to new information.</dim:field>
