Rio Tinto Group (LSE:RIO) Pulls Back After A Strong Run, Is It Still Below Fair Value?

Listen to the news

Rio Tinto Group (LSE:RIO) has remained in focus after recent performance data showed short term share price softness, with the stock down about 2% over the past week and 8% over the past month.

That recent softness sits against a much stronger backdrop. Despite the pullback, Rio Tinto Group’s share price return since the start of the year is up 17.9%, while the 1 year total shareholder return of 50.7% shows earlier momentum that now looks to be fading near the current £70.59 level.

After a sharp run over 1 year but some recent weakness around £70.59, Rio Tinto Group now hinges on one thing: does the current valuation still offer enough upside for the risk you take?

Most Popular Narrative: 6.5% Undervalued

Against the last close at £70.59, the most followed narrative for Rio Tinto Group points to a fair value of £75.50. This frames the recent pullback as a relatively modest discount that still hinges on execution and commodity demand holding up.

Diversification into battery metals (lithium, copper) through acquisitions and organic project delivery positions Rio Tinto to capture rising demand in electric vehicles, stationary energy storage, and grid infrastructure. These areas are expected to have structurally higher pricing and margins than mature bulk commodities, supporting earnings and improving margin resilience.

See why 274 investors see Rio Tinto Group as 6% undervalued.

Result: Fair Value of £75.50 (UNDERVALUED)

Still, the Rio Tinto Group story can change quickly if weaker iron ore and lithium pricing persists, or if geopolitical setbacks disrupt key growth projects.
