Union Pacific, PepsiCo and others could see their sales take a hit in a US-Mexico trade war
CNBC screened the components of the S&P 500 by their respective revenue exposure to Mexico. Kansas City Southern, Union Pacific, PepsiCo and Nucor were among those with the highest proportion of sales in the country. President Donald Trump said Thursday night that he will impose a 5% tariff on all Mexican imports starting June 10 if Mexico doesn't take steps to secure its border.
