Rio Tinto Shares: Is It Time to Be More Cautious?

Rio Tinto (LON: RIO) shares have surged 18.8 percent year to date and 43 percent over the past 12 months, lifted by stronger precious-metals prices and renewed interest in miners.

But after a rapid six-month rally, some analysts are urging investors to reassess how much optimism is already priced in.

Goldman Sachs cut Rio Tinto to Neutral from Buy and set a 7,400p price target in a note to clients, arguing that valuation now limits further upside.

The bank said Rio’s “near record” earnings and spot free-cash-flow yields are largely reflected in the share price, noting the stock is trading around long-term averages and close to peak EBITDA. The downgrade follows the company’s 2025 results, released Thursday.

Rio reported an 8 percent rise in operating cash flow to $16.8 billion and a 9 percent increase in underlying EBITDA to $25.4 billion, underpinned by stronger copper and aluminium volumes and record Pilbara iron-ore output.

Management highlighted an 8 percent uplift in copper-equivalent production and maintained its 60 percent payout ratio, declaring a $6.5 billion dividend. Chief executive Simon Trott said the group is “on track to achieve 3% CAGR in CuEq production to 2030,” supported by project execution across iron ore, copper and lithium.

Despite these operational gains, analysts are divided. Freedom Capital lifted its target to $97 on expectations of higher copper prices, while JPMorgan and RBC Capital trimmed targets but kept positive or neutral stances. Bank of America also lowered its target but reiterated a Buy rating.

After such a strong run, the key question for investors is whether Rio Tinto shares can continue climbing or whether the rally already reflects the best-case scenario.
