摘要

散户投资者重要性的下降和市场的制度化可以说是由于人们普遍认为个人信息不充分，因此最好使用专业服务(Davis, 2009)。然而，本文提供的证据支持相反的观点。使用全球样本，我们检查零售交易是否在全球范围内具有信息性。总体而言，散户投资者通过与永久价格变化相同的方向进行交易来提高价格效率，为价格发现贡献了24.8%，并加速了预定和非预定新闻的信息被捕获到价格中。

Does retail trading matter to price discovery?

Abstract The diminishing importance of retail investors and the institutionalization of markets are arguably a result of the general perception that individuals are not well informed and, hence, are better off using professional services (Davis, 2009). However, this paper provides evidence supporting the opposite. Using a global sample, we examine whether retail trading is informative around the world. Overall, retail investors are documented to enhance price efficiency by trading in the same direction as permanent price changes, contributing 24.8 % to price discovery, and accelerating the information from both scheduled and unscheduled news to be impounded into prices.

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.
