Abstract  

[Objective] This paper explores the impacts of financial news on the stock market fluctuations.[Methods] We used the method of “Word2Vec+k-means” to cluster news texts, and utilized VAR model to analyze the relationship between different types of news and the stock market performance.[Results] The sentiments and information of news significantly affect the trading volumes, amplitudes and returns of the stock market. Meanwhile, the fluctuations of stock market also influenced the emotion and length of the news reports.[Limitations] We did not analyze the relationship between the individual stock and news reports.[Conclusions] There are interactions and time-lag effects between news and stock market, while the news category is a key player.
Key words： Heterogeneous News      VAR Model      Stock Market      Sentiment Analysis
