BHP vs Rio Tinto: Which Big Miner Looks Better After the Latest Sell-Off?

Australia’s two largest diversified miners have both been caught in the recent materials-sector sell-off. Weaker iron ore prices, softer Chinese steel demand signals and broader risk-off sentiment pushed the sector lower through mid-to-late October 2026.

Both stocks closed on 23 October near multi-month lows, with technical indicators flashing oversold readings. However, differences in their commodity exposure, price performance and dividend profiles could influence how they perform if the downturn continues.

BHP: Holding Up Relatively Better

Closing price: $55.05
Daily decline: 3.64%
Distance from 52-week high: Around 20%

BHP closed at $55.05 on 23 October, after falling to an intraday low of $54.78. The stock is trading well below its August 2026 high of $68.77, although it remains further above its 52-week low of $40.18 than Rio Tinto does in percentage terms.

Momentum indicators suggest significant selling pressure. Its 14-day relative strength index (RSI) sits around 29.5, a level commonly associated with oversold conditions. The share price is also below its short- and medium-term moving averages, with the 200-day average near $57.70 providing a longer-term reference point.

The $54.50–$55 zone is an area investors may watch for potential support. However, an oversold RSI does not guarantee a rebound, and sustained selling could push the price lower.

BHP’s commodity mix offers another consideration. Iron ore remains a major earnings contributor, while copper is becoming increasingly important. Recent production updates showed solid Western Australia iron ore volumes, but weaker commodity prices could still pressure earnings and cash flow.

BHP’s trailing dividend yield is around 4.4%, based on the figures provided, with recent dividends fully franked. Future distributions will depend on earnings, commodity prices and the company’s capital allocation decisions.

Rio Tinto: Deeper Oversold Conditions, Greater Drawdown

Closing price: $146.27
Daily decline: 2.68%
Distance from 52-week high: Around 25%

Rio Tinto closed at $146.27 on 23 October, after trading as low as $146.01. Its 52-week high stands at $195.84, putting the stock around 25% below that level. The 52-week low is $125.50.

Rio’s 14-day RSI is near 22, indicating more extreme oversold conditions than BHP’s. The share price is also below its major moving averages, reflecting persistent downward momentum.

The $146 area is an important short-term level to monitor. A sustained recovery above declining moving averages could indicate improving momentum, but a single bounce would not necessarily confirm a trend reversal.

Rio remains heavily exposed to iron ore through its Pilbara operations, while aluminium and copper provide additional sources of earnings. Copper production growth at Oyu Tolgoi and the ongoing ramp-up of the Simandou project are important developments to watch. However, their contribution to future earnings will depend on production execution, costs and commodity prices.

Rio’s trailing dividend yield is in the mid-to-high 4% range, based on the figures provided. As with BHP, future payouts are sensitive to commodity prices and free-cash-flow generation.

What Could Determine the Winner?

The comparison comes down to three key factors.

1. Iron ore prices and Chinese steel demand

Both miners remain exposed to iron ore market conditions. Continued weakness in Chinese steel demand or lower iron ore prices could weigh on earnings expectations and share prices. A recovery in demand could provide relief to both.

2. Copper growth and commodity diversification

BHP’s growing copper contribution could become increasingly important if copper prices strengthen. Rio also has meaningful copper exposure through Oyu Tolgoi, alongside its aluminium business. The relative benefit will depend on production growth, operating costs and realised prices.

3. Signs of a technical recovery

Both stocks are showing oversold readings, but neither has established a clear reversal based on the figures provided. Investors may watch trading volume, support levels and whether prices recover above key moving averages before concluding that selling pressure is easing.

BHP vs Rio Tinto: Which Looks Better?

BHP appears relatively more resilient based on its smaller percentage decline from the stated 52-week high. Rio Tinto, meanwhile, has a deeper oversold RSI reading and a larger drawdown, which may attract attention from investors watching for a potential recovery.

However, neither metric establishes which stock offers better value. BHP’s growing copper exposure and Rio’s aluminium and copper operations provide different earnings drivers, while both remain sensitive to iron ore prices.

The next moves in iron ore and copper, together with upcoming production and financial updates, will be important in determining whether either miner can recover from the sell-off.
