Rio Tinto Shares Climb 17.7% as Commodities Cycle Turns

Rio Tinto shares have risen 17.7% since the start of 2025, a move that tracks the broader commodity recovery more than any company-specific catalyst. The miner, whose earnings are heavily weighted toward iron ore, copper, and aluminium, benefits from steadier demand out of China and tighter supply in seaborne ore markets.

Valuation models for Rio Tinto are straightforward: strip out the commodity price assumptions and the rest is cost execution. That is why the stock's current Alpha Score of 62 out of 100 lands in the moderate zone – not cheap enough to ignore macro risk, not expensive enough to dismiss on multiples alone. The score reflects a balance between earnings momentum and the cyclicality baked into the base-metals outlook.

The real question for any Rio Tinto holder is whether the commodity cycle has further to run. Iron ore, the biggest profit driver, has held above $100 a tonne for most of 2025, supported by Chinese steel margins and port inventory drawdowns. Copper has been stronger still, with supply deficits tightening across the smelting chain. Yet both markets remain sensitive to macro shocks – a slowdown in Chinese property, a sudden U.S. recession, or a collapse in European industrial output would hit Rio's earnings faster than most diversified miners.

For traders looking to frame Rio Tinto within the broader mining cycle, the same valuation framework applies to BHP and other large-cap peers. Rio Tinto reports production results in the coming weeks, and those numbers will give the next real read on whether the stock's 17.7% rally has room to run or needs a breather.
