Where the S&P 500 Faces Brexit Exposure

Written by John Butters | Jun 17, 2016

The United Kingdom will be a focus for the market during the upcoming week, as the country is scheduled to hold a vote on June 23 regarding its membership in the European Union. There are concerns in the market about the potential negative impact on the economy of the United Kingdom should the country decide to leave the European Union. Given these concerns, how much revenue exposure does the S&P 500 have to the United Kingdom? Which sectors and companies in the index have the highest revenue exposure to the UK?

According to FactSet Market Aggregates and FactSet Geographic Revenue Exposure data (based on the most recently reported fiscal year data for each company in the index), the aggregate revenue exposure of the S&P 500 to the United Kingdom is 2.9%. This is the third highest country-level revenue exposure for the index, trailing only the United States (68.9%) and China (4.8%).

At the sector level, the Energy (6.4%) and Information Technology (4.0%) sectors have the highest revenue exposures to the United Kingdom.

At the company level, 29 companies in the S&P 500 have revenue exposure of more than 10% to the United Kingdom, led by Molson Coors Brewing (34%) and PPL Corporation (31%). 

Prices Increase for Companies with High UK Revenue Exposure

It is interesting note that since February 20 (the date the UK announced the June 23 timeline for the EU vote), the companies in the S&P 500 with more revenue exposure to the UK have seen higher average and median price increases relative to the index as a whole.
