LSTM Model for Explaining the Association between News Data and Stock Price Fluctuations

Abstract

Research on the association between stock price fluctuations and news data is popular andnumerous studies have been conducted. This paper aims to improve the accuracy of text classification intothree categories (negative, neutral, or positive) by employing high frequency data and LSTM model. Oneof the novelties of our paper is to use several types of news articles in the analysis.
