Abstract

News is an important source of information for investment decision-making. Many studies analyzing listed companies in the US & Japan have been reported. However, the number of studies focusing on Korean stock markets is limited. This study analyzes the influence of news articles on Korean stock markets with high frequency trading data. Especially, we focus on analyses of the relationship between news articles and financial markets. Furthermore, we also analyze differences in market reactions according to language (English or Korean) of news articles and present three case studies.
