Freeport-McMoRan Inc. stock (ISIN US35671D8570) came under heavy pressure as of September 10, 2026, with shares dropping around 7% alongside a sharp reversal in copper prices amid ongoing uncertainty over potential U.S. refined copper tariffs, putting valuation and tariff risk firmly back on investors' radar.

Valuation signals: GF Value and year-to-date performance
Several valuation-focused analyses suggest that Freeport-McMoRan stock is currently trading at a significant premium to intrinsic value estimates. According to GuruFocus, Freeport-McMoRan shares were at USD 70.83 on September 10, 2026 compared with a GF Value estimate of USD 48.97, implying the stock was 44.6% overvalued.
A separate GuruFocus assessment put the price at USD 71.21 on September 10, 2026 versus the same intrinsic value estimate of USD 48.97, calculating a 45.4% margin of overvaluation and reinforcing the message that the share price is far above that proprietary fair value metric.GuruFocus
A third GF Value article reports Freeport-McMoRan trading at USD 70.62 as of September 10, 2026, still about 44.2% above the GF Value estimate of USD 48.97, underscoring that different snapshots all point to an overvaluation in the mid-40 percent range according to this methodology.GuruFocus
MarketBeat notes that Freeport-McMoRan shares started 2026 at USD 50.79 and had risen to around USD 71.15 by early September 2026, corresponding to a gain of roughly 40.1% year-to-date, which contextualizes the recent pullback against a strong multi-month rally.MarketBeat
Analyst views and price targets
Despite the latest volatility and valuation questions, analyst consensus remains broadly constructive. According to an instant alert summary from MarketBeat dated September 11, 2026, one analyst rates Freeport-McMoRan stock as Strong Buy, twenty as Buy and four as Hold, resulting in a consensus rating of Moderate Buy with a consensus price target of USD 69.75.
Another MarketBeat article on September 11, 2026 that discussed Erste Group Bank's outlook on Freeport-McMoRan's fiscal 2027 earnings also repeated that the average target price stands at USD 69.75, indicating that the current trading levels slightly above USD 71 leave the stock just above consensus fair value.MarketBeat
GuruFocus notes that Goldman Sachs has maintained a Buy rating on Freeport-McMoRan despite the tariff-related uncertainty, citing the company's underlying value and long-term copper demand trends as support factors even as policy risks weigh on short-term sentiment.GuruFocus
Operational backdrop and Grasberg ramp-up plans
In parallel with the market reaction to tariffs, Freeport-McMoRan's operational agenda is centered on restoring and expanding production at its key Grasberg mine. As reported in a commodities-focused article, Grasberg is ramping back up after a fatal underground incident, with Freeport targeting about 65% of capacity in the second half of 2026, rising to 80% by mid-2027 and near-full capacity by year-end 2027.Yahoo Finance
This staged ramp-up offers a medium-term volume growth story but also adds execution risk, particularly given the sensitivity of underground operations and the need to maintain safety standards while increasing output to benefit from structural copper demand.
Sector commentary from Briefed Media emphasizes that copper remains central to energy transition and data center build-out themes, meaning Freeport-McMoRan, as a leading copper producer, remains at the heart of the so-called 'copper trade' even if near-term policy decisions can temporarily overshadow fundamentals.Briefed Media
Tariff risk, overvaluation debate and investor takeaway
The combination of unresolved refined copper tariff plans and valuation metrics suggesting Freeport-McMoRan stock is trading 40% to 45% above certain intrinsic value estimates has sharpened the debate over risk and reward for investors in September 2026. On one hand, the stock's roughly 40.1% advance since the start of 2026 reflects strong earnings support from higher copper prices and optimism about long-term demand.Yahoo Finance
On the other hand, GF Value calculations at prices around USD 70.67 to USD 71.21 point to overvaluation of more than 44%, suggesting that a portion of the rally already prices in optimistic scenarios for copper and company execution, leaving the shares vulnerable when policy headlines turn negative.GuruFocus
The tariff question acts as a key counter-factor: should refined copper tariffs be implemented at significant levels, downstream manufacturing costs could rise and demand dynamics might change, potentially compressing margins and impacting cash flows for Freeport-McMoRan and peers. Current sector notes mention that Hudbay Minerals dropped roughly 6.9% on September 10, 2026 in parallel with Freeport-McMoRan's move, highlighting how quickly tariff-related news can ripple across copper miners.GuruFocus
