Southern Copper shares fell 2.4 percent even as investors ask if it can extend its record of positive earnings surprises.
What happened
Southern Copper fell 2.4 percent today, a move larger than 70 percent of its daily swings over three years. The market is broadly slipping, with prices trending down despite a still constructive overall trend. Oil prices have jumped 8.1 percent in the past week.
Why it matters
Higher oil prices raise extraction and smelting costs for miners like Southern Copper. If the company cannot pass those costs on, rising expenses would compress margins and threaten its streak of beating profit estimates, which has supported its market value.
The case against
If the rally in oil signals stronger global industrial demand, copper prices could also rise and more than offset higher energy costs. Southern Copper’s track record of positive surprises also suggests management is adept at controlling the variables within its power.
What settles it
The spread between copper prices and oil prices over the next two weeks will show whether rising costs are outpacing potential revenue.
