摘要

我们使用四个与英国脱欧相关的公告作为外生信息冲击的来源，研究了七个主要欧洲股票市场的半强效率形式。我们的研究结果表明，只有英国脱欧公投结果的公布才会在样本市场上产生具有统计学意义的负累积异常回报。然而，除爱尔兰股市外，这种影响在事件发生后的五个交易日内不再显著。我们还记录了在公投当天和随后几天交易活动的增加，尽管在统计上微不足道。总的来说，我们的结果符合市场效率的半强形式。

STOCK MARKET REACTION TO BREXIT ANNOUNCEMENTS: EVIDENCE FROM A NATURAL EXPERIMENT

Using four Brexit-related announcements as a source of exogenous information shocks, we investigate the semi-strong form of efficiency in seven major European stock markets. Our results suggest that only the announcement of the Brexit referendum result produced statistically significant negative cumulative abnormal returns in the markets of the sample. However, with the exception of the Irish stock market, the effects ceased to be significant in a period of five trading sessions after the event. We also document an increase in trading activity, though statistically insignificant, in the day of the referendum and in the following days. Overall, our results are in line with the semi-strong form of market efficiency.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
