BofA Securities has upgraded its positioning on European mining stocks to marketweight from underweight, arguing that the sector's recent decline leaves limited further downside when viewed through the lens of the bank's macro scenario.
The brokerage pointed out that European mining has lagged the broader market by 15% since early June. That weakness followed a period of strong outperformance, during which the sector had beaten the market by 65% between June 2025 and June 2026.
BofA attributes the recent correction mainly to valuation moves rather than to deterioration in expected earnings. The firm said the sector's price-to-earnings ratio versus the market swung from a 10-year high - when mining traded at a 5% premium to the market - to a 20% discount. Over the same interval, 12-month forward consensus earnings per share for mining relative to the market continued to rise, according to the brokerage.
The bank also tied the pullback to prior commodity price dynamics, noting that copper climbed 55% to reach a record peak of $14,000 a ton in May before easing about 10% from that high.
Another central theme BofA highlighted is the sector's increasing correlation with AI-related market sentiment. The brokerage described mining as having taken on more of a "picks and shovels" profile in relation to the AI capital expenditure cycle, given the implications for copper demand stemming from grid and electricity generation buildout. As a result, mining has become one of the top four sectors most closely correlated with AI trade proxies, the firm said.
BofA warned this exposure leaves mining vulnerable to an "air pocket" scenario if expectations for AI-driven capex are marked down. The brokerage noted that several AI-sensitive proxies - including the Nasdaq, the Korean KOSPI and the MSCI Europe AI capex beneficiary index - have retreated recently amid doubts over the durability of the capex ramp-up. Mining has tended to follow those moves in sympathy.
Prior to the most recent downturn, BofA had maintained an underweight view on mining. The bank explained that it saw the sector as cyclical and had been concerned that it was overpricing the potential for a broad global macro acceleration. It was also wary that AI-related expectations had become excessively optimistic.
On macro signals, BofA pointed to a stronger-than-anticipated rebound in global macro surprises - a proxy it uses for global growth momentum. That rebound was aided, the firm said, by a U.S.-Iran ceasefire and the consequent decline in the oil price. Relative to those macro surprises, mining is now undershooting its historical relationship after previously overshooting it, according to BofA.
In terms of positioning, the brokerage said it remains cautious on large-cap mining names in the near term but is constructive on the sector over the medium term.
Key takeaways
- Valuation-driven pullback: European mining has underperformed by 15% since early June after a prior 65% outperformance between June 2025 and June 2026.
- Copper role: A 55% rally in copper to $14,000 a ton in May, followed by a roughly 10% fade, has been a notable factor in recent sector volatility.
- AI sensitivity: Mining is increasingly trading as a beneficiary of AI capex expectations, raising correlation risk with AI-focused indices and proxies.
Risks and uncertainties
- AI capex re-pricing - If expectations for AI-driven capital expenditure are revised lower, mining could face abrupt downside through reduced sentiment-driven demand; this affects miners, copper markets, and related industrial sectors.
- Valuation volatility - Continued de-rating could pressure large-cap miners in the near term even if earnings expectations remain intact; this primarily impacts equity holders in the mining sector.
- Macro surprise swings - Changes in global macro momentum, which the bank measures with global macro surprises, could alter the sector's relationship with growth signals and price action across commodities and mining equities.
