Abstract

Twitter is the US president’s, Donald Trump, preferred media for communicating his thoughts to his followers. This project looks at the effect of the daily flow of Donald Trump’s tweets on the US financial and foreign exchange markets, represented by the Dow Jones Industrial Average (DJI) index and some exchange rates, over the period of Donald Trump’s ongoing presidency. Using text mining techniques, some correlation is found between various moving average window lengths of tweet content and the DJI index. Some short term and lasting effects are also detected on US-Canada and US composite exchange rates.
