Southern Copper stock has delivered very strong returns over the past few years, yet the current valuation checks suggest the shares are not cheap. After a long run up, investors now have to weigh that track record against signals that the stock screens as expensive on several measures.

• Southern Copper has returned 289.4% over the past 5 years, which means anyone buying today is paying a much higher price than long term holders did.
• Strong recent revenue and earnings momentum tied to copper demand for electrification and infrastructure can support the current share price, but any slowdown in those end markets may quickly test how much investors are willing to pay.
• Southern Copper scores 0 out of 6 on the broader valuation checks, which indicates the stock does not come across as a clear bargain on Simply Wall St's valuation summary.

The stock's next move may depend on whether Southern Copper's fundamentals can keep justifying a richer valuation after such a strong multi year run.

Southern Copper delivered 119.6% returns over the last year. See how this stacks up to the rest of the Metals and Mining industry.

Is Southern Copper Getting Expensive on Earnings?

The P/E ratio is a useful starting point for Southern Copper because earnings are a direct link between copper prices, production volumes and what shareholders are currently paying.

Southern Copper trades on a P/E of about 28.8x, which is well above the Metals and Mining industry average of roughly 16.2x and the peer group average near 19.9x. Based on Simply Wall St's fair P/E estimate of about 22.8x, which reflects the company’s profile and risk, the stock is pricing in a sizeable premium to what this framework suggests would be a more typical level.

Despite the recent Q2 2026 beat on revenue and earnings, the current P/E still implies that Southern Copper is already priced for strong conditions and leaves less room for disappointment compared with many peers.

On the P/E multiple, Southern Copper currently screens as overvalued relative to both its industry and its modelled fair ratio.

The Bottom Line

Southern Copper now trades on richer earnings multiples that point to an overvalued reading on the current checks. That does not rule out further gains, but it does mean you are relying more on the company continuing to deliver strong fundamentals to support the valuation. The key question is whether copper demand, project execution and profitability stay strong enough to keep justifying this premium versus peers.
