The financial costs of political uncertainty: Evidence from the 2016 US presidential elections

Abstract

The victory of Mr. Donald Trump came as a surprise to a wide range of market participants. Some of the elements of his economic plan were envisaged to affect all US sectors. This paper assesses the reactions of disaggregated US stock market to the 2016 US presidential election results, and possible deregulation that is to follow after his inauguration. We find that the different US sectors were significantly and varyingly influenced by the election result, and were greatly reactive during the days after the inauguration. This underscores that uncertainty tends to persist and even rises since the President-elect took office.
