Southern Copper Stock at a Critical Juncture

Shares of Southern Copper Corporation find themselves at a pivotal crossroads. The mining giant is back in the spotlight, propelled by a recent analyst upgrade and surging global copper prices. While the stock trades near its annual peak, the actions of institutional investors and company insiders are painting a complex and contradictory picture.

The equity's strength is inextricably linked to a powerful rally in the commodity markets. On Friday, December 5, US copper futures surged to $11,540 per tonne. This movement is being driven by two primary catalysts: mounting concerns over impending US import tariffs on refined copper, set to begin in January 2027, and persistent global supply constraints amid robust demand.

In response to this environment, analysts at Citi have revised their forecast upward, projecting that copper prices could reach $12,000 per tonne by the second quarter of 2026. This macroeconomic backdrop provided significant support, with Southern Copper's stock advancing 1% during Friday's trading session.

A Wall Street Upgrade Amidst Caution

The bullish case received a boost on Saturday, December 6, 2025, when Wall Street Zen upgraded its rating on Southern Copper from "Hold" to "Buy." This reassessment comes as the shares trade around $140.55—hovering perilously close to their 52-week high of $144.81. The upgrade is grounded in solid operational performance. For the third quarter of 2025, the company reported earnings per share (EPS) of $1.35, decisively beating the market consensus estimate of $1.26. Revenue of $3.38 billion also surpassed the forecast of $3.05 billion.

Should investors sell immediately? Or is it worth buying Southern Copper?

However, the broader analyst consensus remains cautious, maintaining an average "Hold" rating with a price target of $117.94. This suggests a perceived downside risk from the current valuation level.

Institutional and Insider Activity Reveals a Split

Recent regulatory filings reveal a clear divergence in institutional strategy. Norges Bank has taken an aggressive stance, purchasing 572,315 shares valued at approximately $57.9 million. American Century Companies Inc. also increased its stake by 21%, now holding over 75,000 shares.

In stark contrast, Marshall Wace LLP has taken profits, reducing its position by 52.6%. The fund now holds 684,695 shares. This institutional split is mirrored in recent insider activity. A company director sold 400 shares on December 3 at a price of $139 per share. Although the volume is relatively small, insider sales near all-time highs often signal a belief that the equity is fully valued in the short term.

Investors are currently balancing the immediate windfall from soaring copper prices against the stock's premium valuation. With the share price trading significantly above the average analyst target, the market is betting on a continuation of the commodity boom. The next major test for the stock will likely be the release of quarterly results in January.
