Abstract

This study investigates the impact of political news on stock price movements. Analyzing more than 3,200 tweets from US President Donald Trump’s Twitter account, we find that tweets related to the US-China trade war negatively predict S&P 500 returns and positively predict VIX. Granger causality estimates indicate that the causal relationship is one-directional – from Trump tweets to returns and VIX. Finally, the results vary across industries depending on their degree of trade intensity with China.

Keywords: Granger causality, Political news, Trump, Twitter, Trade war

JEL Classification: F1, F4, G1
