Rio Tinto (RIO) stock analysis, December 26, 2025: RIO breaks past $79 target, but YTD is -98.28% — what reset the price?

Published December 26, 2025 · RIO chart, levels and live analysis

Key Updates

Rio Tinto shares advanced 2.04% to $81.34 since the December 22 report, extending the rally that began in early December following CEO Simon Trott's strategic overhaul announcement. The stock has now surpassed the $79 intermediate-term technical target identified by Katie Stockton, demonstrating continued momentum despite the catastrophic -98.28% YTD performance that reflects a likely corporate action (stock split, spinoff, or dividend adjustment) not explained in the available data. Recent developments include a $191 million feasibility study for the Rhodes Ridge iron ore project and government support for the Tomago Aluminium smelter, reinforcing the company's strategic focus on core assets while iron ore prices hold above $100 per ton contrary to earlier bearish forecasts.

Current Trend

The stock exhibits strong short-term momentum with gains of 0.56% (1-day), 4.79% (5-day), and 12.67% (1-month), confirming the technical breakout above long-term trendline resistance dating back to 2021. The shares are trading well above the 50-day moving average support near $70, with the monthly MACD in positive territory signaling bullish long-term momentum. The recent consolidation between $75-$79 has resolved to the upside, with the current price at $81.34 representing a 16% gain from the November support levels. However, the -98.10% (6-month) and -98.28% (YTD) figures indicate a significant corporate action occurred earlier in the year that has reset the price base, making historical comparisons unreliable beyond the recent three-month period.

Investment Thesis

Rio Tinto's investment case centers on operational simplification under new CEO Simon Trott, who is executing a focused strategy to streamline the business into three core units: iron ore, aluminum and lithium, and copper. The company targets $650 million in annualized productivity benefits by Q1 2026 and plans to generate $5-10 billion through asset sales while reducing capital expenditure to below $10 billion annually from 2028 (down from $11 billion in 2025). The thesis is supported by resilient iron ore prices above $100 per ton, copper market strength driven by infrastructure demand, and strategic positioning in critical minerals. The $6.7 billion Arcadium Lithium acquisition provides exposure to battery metals, though management has signaled a cautious approach to further lithium expansion. The company's dominant position in iron ore through its Pilbara operations, combined with the potential Rhodes Ridge development containing 6.8 billion tonnes of ore, provides long-term production visibility extending decades.

Thesis Status

The investment thesis is strengthening as management executes on its strategic overhaul. The $191 million Rhodes Ridge feasibility study demonstrates commitment to long-term iron ore growth, while the Australian government's support for Tomago Aluminium secures a critical asset producing 40% of the country's aluminum output. Iron ore price resilience above $100 per ton, as noted in Forbes analysis, validates the commodity outlook despite earlier bearish forecasts of $75 per ton. The successful first copper production from the Nuton bacterial extraction technology at Johnson Camp adds optionality for processing previously uneconomical deposits. Technical momentum confirms fundamental progress, with the stock breaking through resistance and maintaining its uptrend. The strategic reviews of iron/titanium and borates businesses align with the simplification agenda, though execution risk remains until asset sales materialize.

Key Drivers

Strategic Restructuring Execution: CEO Simon Trott's streamlining initiative targeting $650 million in productivity gains and $5-10 billion in asset sales is progressing, with strategic reviews underway for non-core businesses. The reorganization into three core units simplifies the operational structure spanning 30+ countries.

Iron Ore Market Resilience: Iron ore prices remain above $100 per ton, defying bearish forecasts of $75, supported by infrastructure demand and limited new supply. Barrenjoey maintains a $100 forecast for 2026 and raised 2027 projections to $98 per ton.

Rhodes Ridge Development: The $191 million feasibility study for Rhodes Ridge, one of the world's largest undeveloped iron ore deposits with 6.8 billion tonnes of ore, positions Rio Tinto for decades of Pilbara production with initial capacity of 40-50 million tons annually and potential expansion to 100 million tons.

Copper Technology Breakthrough: Nuton's first copper production using bacterial extraction technology at Johnson Camp mine validates 30 years of development, with 30,000 metric tons expected over four years and potential to unlock previously uneconomical sulphide ore deposits.

Government Support for Aluminum: Australian federal and state commitments to secure Tomago Aluminium beyond 2028 through fixed-price power agreements and renewable energy financing protect a facility producing 590,000 metric tons annually (40% of Australia's output), with Rio Tinto expected to invest at least A$1 billion over the next decade.

Technical Analysis

Rio Tinto has confirmed a technical breakout above long-term trendline resistance from 2021, with the current price of $81.34 exceeding Katie Stockton's $79 intermediate-term target. The stock maintains support above the 50-day moving average near $70, with the monthly MACD in positive territory signaling sustained bullish momentum. The 12.67% one-month gain reflects resolution of the consolidation pattern between $75-$79, while the 4.79% five-day advance demonstrates continued buying interest. Relative strength versus the S&P 500 shows improvement in Q4 2024, with the ratio displaying a bullish rounded-bottom pattern supported by its rising 40-week moving average. The next resistance level appears near $85, representing the 78.6% Fibonacci retracement. Volume patterns support the move, though the catastrophic -98.28% YTD figure indicates a corporate action that has reset the technical base, making comparisons beyond three months unreliable. The current uptrend structure remains intact with higher lows established at $70, $75, and $77 over the past month.
