EcoPetrol, Colombia's state-owned oil monopoly, stands to benefit significantly if right-wing candidate Esperilla wins the June 21st runoff election, as he has pledged to increase oil production from 700k to 1.3M barrels/day and deregulate energy exploration. Key risks include a potential upset victory by leftist candidate Cepeda, which would continue anti-oil policies and could send the stock below its current $15.50 level, though the company was once valued above $50 in the early 2010s.
