This document provides an empirical analysis of Donald Trump's potential effects on the Mexican peso. It suggests that the exchange rate is undervalued by as much as 15% and could be a profitable strategy if Hillary Clinton wins the US presidential election. However, due to high risks associated with the US election, BofA Merrill Lynch remains neutral for now. The report also includes a model of MXN weekly returns that considers Trump's RealClearPolitics polling average in the US presidential election as one of its variables.
