What Would It Take For Southern Copper Stock To Do It Again?
Southern Copper Corporation (SCCO) mines copper in Mexico and Peru, while also selling molybdenum, silver and zinc. The stock has climbed 222% before dividends since June 30, 2021. Investors might easily attribute a gain of that magnitude to the underlying business. So take a guess: how much of that rise came from Southern Copper simply selling more?
How Much Did Southern Copper’s Sales Grow?
Southern Copper recorded $15.8 billion in sales over the last twelve months, compared with $9.9 billion five years ago. That represents a 59% increase, against the 222% advance in the stock.
On a compounding basis, expanding sales account for about two-fifths of the stock price appreciation. This growth was real, and no other single factor explains as much of the overall gain.

What Else Lifted Southern Copper Stock?
Three other elements contributed the remaining three-fifths of the advance, as detailed below.
| Source | Five years ago | Now | Share of the stock’s rise |
|---|---|---|---|
| Sales, last twelve months | $9.9 billion | $15.8 billion | 40% |
| Net margin | 28.2% | 35.9% | 21% |
| Price-to-earnings multiple | 19 | 30 | 39% |
| Share count | down 1% | 1% |
The four shares add up to 100%. A negative share means that source pulled the price down. Split-adjusted share price, dividends excluded.
The main driver among these elements is the price-to-earnings multiple, which measures what investors will pay for each dollar of profit. This metric climbed to 30.4 from 19.2 five years ago, standing alone to account for nearly two-fifths of the total stock increase. A wider net margin, indicating the portion of sales retained as profit, makes up about a fifth of the rise. Meanwhile, the overall share count saw almost no change.
Expanding multiples and wider margins clearly benefit shareholders, yet they are structurally different from an increase in sales.
Can Margins And Multiples Keep Rising?
The company currently reports a net margin of 35.9%, marking a ten-year high. Its valuation multiple remains comfortably within the 14.2 to 54.3 range recorded over the identical ten years.
Sales have the potential to grow as long as Southern Copper moves higher metal volumes or secures better prices. However, a business eventually hits a ceiling on how much of each dollar it can retain, just as investors hit limits on what they will pay for earnings. Consequently, a wider margin and a higher multiple do not repeat the way sales growth can.
What Southern Copper Would Need To Repeat Its Rise
Assuming the margin, multiple and share count remain fixed, Southern Copper would need 24.8% annual sales growth to match its previous yearly pace of returns. That target sits well above the 9.2% annual growth rate sales have averaged since mid-2021.
Recent numbers are running higher, with sales up 33% over the latest twelve months. During the second quarter of 2026, copper sales increased 38% on better metal prices, according to management, even though the company sold 1.5% less copper.
Going forward, the key metric to monitor is Southern Copper’s yearly sales growth against that 24.8% benchmark.
Your Advisor Retired? Get A Second Opinion Before You Settle
Much of what Southern Copper holders have gained came from something other than sales growth.
