Rio Tinto (RIO) stock analysis, December 22, 2025: RIO clears $79 target, but can iron ore hold above $100?

Published December 22, 2025 · RIO chart, levels and live analysis

Key Updates

Rio Tinto shares advanced 2.87% to $79.72 since the December 17 report, reaching the intermediate-term technical target of $79 identified by analyst Katie Stockton. The rally continues to be supported by iron ore price resilience, with prices holding above $100 per ton despite earlier predictions of a decline to $75. Most significantly, Rio Tinto announced a $191 million feasibility study for the Rhodes Ridge iron ore project, one of the world's largest undeveloped deposits with 6.8 billion tonnes of ore and potential annual production capacity of 40-50 million tons initially, expandable to 100 million tons.

Current Trend

Rio Tinto has exhibited strong short-term momentum with gains of 1.78% (1d), 5.14% (5d), and 13.90% (1m), recovering from the catastrophic YTD decline of -98.31%. The stock has successfully broken through the $79 resistance level and is now testing new technical territory. The recent price action confirms the technical breakout above long-term trendline resistance dating back to 2021, with the monthly MACD indicator in positive territory signaling bullish long-term momentum. Support remains at the 50-day moving average near $70, providing a 12% downside cushion from current levels.

Investment Thesis

The investment thesis centers on Rio Tinto's strategic transformation under CEO Simon Trott, focusing on operational simplification, cost reduction, and capital discipline. The company's plan to generate $5-10 billion from asset sales, reduce capex to below $10 billion annually from 2028, and achieve $650 million in annualized productivity gains positions Rio Tinto for improved returns. The core focus on iron ore and copper aligns with structural demand drivers, particularly as iron ore prices defy bearish forecasts and remain above $100 per ton amid a broader commodities boom. The Rhodes Ridge project provides multi-decade production visibility, while the Nuton copper processing technology offers competitive advantages in extracting copper from previously uneconomical deposits.

Thesis Status

The investment thesis is strengthening materially. The Rhodes Ridge feasibility study announcement represents a significant positive development not anticipated in previous reports, providing concrete evidence of Rio Tinto's long-term growth pipeline in its core iron ore business. The project's scale—potentially one of the world's largest iron ore operations—validates the company's strategic focus on premium assets. Iron ore price resilience above $100 per ton, with Barrenjoey maintaining forecasts at $100 for 2026 and raising 2027 projections to $98 per ton, supports near-term earnings visibility. The technical breakout confirmation and positive momentum indicators align with fundamental improvements. However, the cautious approach to lithium following the $6.7 billion Arcadium acquisition and plans to slow or mothball lithium projects introduces execution risk around capital allocation decisions.

Key Drivers

The Rhodes Ridge feasibility study represents the primary new catalyst, with the $191 million investment signaling commitment to long-term iron ore production growth. The study, expected to conclude in 2029, evaluates initial production of 40-50 million tons annually from a deposit containing 6.8 billion tonnes of ore. This follows Mitsui's $5.2 billion acquisition of a 40% stake earlier in 2025, demonstrating strong partner confidence. Iron ore price resilience above $100 per ton, driven by infrastructure demand and a broader commodities boom affecting copper, gold, and silver, provides favorable market conditions. The company's strategic restructuring continues to progress, with workforce reductions and productivity initiatives underway. Additionally, Australian government support for the Tomago Aluminium smelter, including fixed-price power agreements and renewable energy financing, removes a significant operational risk for the country's largest aluminum facility.

Technical Analysis

Rio Tinto has reached the $79 intermediate-term target identified by Katie Stockton at the 61.8% Fibonacci retracement level, representing a key test of resistance. The stock has confirmed a technical breakout above long-term trendline resistance dating back to 2021, resolving a multiyear consolidation phase. The monthly MACD indicator in positive territory signals bullish long-term momentum, while the weekly MACD supports the intermediate-term uptrend. Support remains at the 50-day moving average near $70, providing a clearly defined risk level. Relative to the S&P 500, RIO displays a bullish rounded-bottom pattern supported by its rising 40-week moving average, suggesting potential outperformance in H1 2026. The current price action at $79.72 represents a breakout above the technical target, indicating potential for further upside if momentum continues, though some consolidation at this level would be technically healthy.
