Rio Tinto (RIO) stock analysis, December 12, 2025: RIO holds $70 support after Tomago deal, but $79 resistance caps the rally

Published December 12, 2025 · RIO chart, levels and live analysis

Key Updates

Rio Tinto shares declined 2.16% to $75.29 since the December 11 report, marking a technical consolidation after the recent rally driven by CEO Trott's strategic overhaul. The pullback follows the Australian government's commitment to secure the Tomago Aluminium smelter's future with a fixed-price power agreement, representing a significant operational milestone but insufficient to sustain upward momentum. The stock remains within the established technical range near $70-$79, with the strategic restructuring narrative intact but facing near-term profit-taking pressure.

Current Trend

Rio Tinto exhibits extreme volatility with YTD performance down 98.41%, reflecting a significant data anomaly or corporate action not captured in the provided information. Short-term momentum remains constructive with 1-month gains of 5.88% and 5-day gains of 3.05%, despite the recent 1-day decline of 1.89%. The stock is consolidating above the critical $70 support level identified by the 50-day moving average, with technical analyst Katie Stockton identifying an intermediate-term upside objective near $79 at the 61.8% Fibonacci retracement level. The monthly MACD has moved into positive territory, signaling improved long-term momentum despite the recent pullback.

Investment Thesis

The investment thesis centers on Rio Tinto's strategic transformation under new CEO Simon Trott, focusing on operational simplification, cost reduction, and concentration on core high-margin assets. The company is executing a $10 billion asset divestiture program while streamlining operations into three core units: iron ore, aluminum and lithium, and copper. Management targets $650 million in annualized productivity gains, 4% unit cost reduction through 2030, and capital expenditure reduction to below $10 billion annually from 2028. The thesis is underpinned by copper demand growth driven by energy transition, with 7% copper equivalent production growth targeted for 2025 and 3% compound annual growth through 2030. The cautious approach to lithium following the $6.7 billion Arcadium acquisition reflects disciplined capital allocation, while innovative technologies like Nuton copper extraction and low-emissions iron production position the company for long-term sustainability.

Thesis Status

The investment thesis remains fundamentally intact with execution progressing as planned. The Australian government's commitment to Tomago Aluminium, requiring at least A$1 billion investment over the next decade, validates the aluminum business as a core holding and secures 40% of Australia's aluminum output beyond 2028. The successful first copper production from Nuton technology at Johnson Camp, targeting 30,000 metric tons over four years, demonstrates technological differentiation and validates the 30-year development investment. However, the recent price decline suggests investor concerns about near-term execution risks, commodity price volatility, and the magnitude of the restructuring challenge. The strategic reviews of iron and titanium and borates businesses are progressing, but uncertainty around divestiture valuations and timing creates near-term overhang.

Key Drivers

The primary near-term driver is the execution of the $10 billion asset divestiture program and strategic reviews of non-core businesses. The Tomago Aluminium agreement secures operational continuity for Australia's largest aluminum smelter, which consumes over 40% of its operating costs in electricity, providing long-term cost visibility in a critical business segment. Nuton technology advancement enables copper extraction from previously uneconomical primary sulphide ores, potentially unlocking significant resource value as copper demand accelerates. The lithium strategy remains a key uncertainty, with management slowing or mothballing projects pending improved returns, reflecting disciplined capital allocation but potentially limiting exposure to battery metals upside. Iron ore price dynamics and Chinese demand remain critical external factors, with weakening prices due to declining global steel demand presenting near-term headwinds.

Technical Analysis

Rio Tinto is consolidating within a $70-$79 range following the breakout above long-term trendline resistance dating to 2021. The stock currently trades at $75.29, holding above the 50-day moving average support near $70 despite the recent 2.16% decline. The monthly MACD indicator has moved into positive territory, signaling bullish long-term momentum, while the weekly MACD supports the intermediate-term uptrend with an upside objective near $79. Relative strength versus the S&P 500 has improved in Q4 2024, with the ratio displaying a bullish rounded-bottom pattern. The recent pullback appears to be a healthy consolidation within the broader uptrend, with volume characteristics not suggesting distribution. Key resistance lies at $79, while critical support remains at $70, with a break below potentially triggering a retest of lower levels.
