Biggest copper mine on strike watch while Russia's oil loadings stall — long copper miners on the supply squeeze

Verdict: A Copper Squeeze Worth Watching, Not Yet Worth Buying

The strongest case for this idea is the catalyst itself: per Bloomberg's October 13 report, BHP is in a final bid to avert a strike at Escondida, the world's largest copper mine, just as copper prices rally — a real supply shock with no easy substitute. The strongest case against is that the catalyst is also the single point of failure, since BHP *averting* the strike removes the thesis overnight, and insiders were already net open-market sellers as of the September 30, 2026 ownership report (provisional coverage): roughly -$6.9M at FCX and -$0.3M at BHP. The completed backtest is too thin to lean on — two BHP trades over nine months, both winners but only about 0.2% total return and a 4.0% drawdown, with exits filled on daily bars. Fundamentals are split: BHP's FY2025 free cash flow of $9.3B sits at the 99th percentile of Materials peers and its 38.0% operating margin in the top decile, but FCX's Q4 2025 snapshot showed a $608M net loss and negative free cash flow, and both names rank in the bottom quintile on revenue growth. No robust parameter setup was established for the strategy, so trade the frozen rules as written or not at all. Right now none of the entry conditions are live — BHP's ADX of 10.3 is roughly half the required 20 — so the verdict is wait at defined levels, not buy.

Trade now

The entry conditions for this copper-miner setup are not live yet, so today the answer is wait — but wait at specific levels. On BHP, price closed at $84.58 versus a 50-day EMA of $86.34, so the required move back above that average has not happened. The RSI (14) sits at 38.6, needing to cross above 50, and the ADX (14) reads 10.3, needing to rise above 20. COPX shows the same shape: $83.87 versus an EMA of $85.62, RSI at 42.6, ADX at 10.2. FCX is closest to triggering — at $71.74 it sits just above its EMA of $70.71 and its RSI of 47.7 is within 2.4 points of the 50 threshold, but its ADX of 9.9 is still roughly half of the required 20. When the setup fires, the strategy's risk framework is explicit: a stop-loss at a 2.3% loss on the position and a take-profit at a 4.6% gain, which is an effective reward-to-risk of about 2-to-1, with positions capped at 25% each. The backtest that did complete — nine months on the BHP pair — produced two trades, both winners, a 0.2% total return and a 4.0% maximum drawdown; the exits were filled on daily bars, so treat those fill-quality figures as approximate. Note that no robust parameter setup was established for this strategy, so the frozen rules above are the ones to trade. What wait means concretely: set alerts at $86.34 on BHP and $85.62 on COPX for the EMA reclaim, watch for each RSI to push through 50, and require the ADX to climb above 20 before any of it counts as an entry. A crossover with the ADX still below 20 would be a weak-trend signal, exactly the kind this strategy is designed to filter out.

Copper Supply Shocks Plus a Backed Bull Case in Miners

The thesis is straightforward: supply shocks in copper, capped by a potential strike at Escondida, should hit miners' equity prices hard and fast, and a basket of BHP, COPX and FCX gives that exposure. Per the Bloomberg piece published October 13, 2026, BHP is in a final bid to avert a strike at the world's largest copper mine precisely as copper prices rally — a strike would remove a large slice of global supply with no easy substitute, and the same day's report of slowing Russian Black Sea oil loadings reinforces the broader supply-disruption backdrop the idea argues from. The rules-based long setup has a completed 9-month backtest on the BHP leg: 2 trades, both winners (a 100% win rate), a total return of about 0.22%, and a maximum drawdown of only 4.0%. Exits were filled on daily trigger bars rather than intraday data, so those exit fills are approximate — but the shape of the evidence is a low-drawdown, signal-driven entry into a sector with a clear catalyst, rather than a naked bet. The fundamentals support owning these names during a copper squeeze. BHP's FY2025 (ended June 30, 2025) operating margin of 38.0% sits in the top decile of Materials peers (92nd percentile of 279), net income rose 14.2% year over year to $9.0B, net margin expanded 3.3 points to 17.6%, and ROE improved to 18.9%. Its $9.3B in free cash flow ranks at the 99th percentile of the sector — the balance-sheet strength to endure a strike without distress. FCX offers the higher-octane copper beta into the same catalyst. Its Q2 2026 (ended June 30, 2026) revenue rose 10.6% sequentially to $6.9B, operating cash flow jumped 37% to $2.0B, and gross margin expanded 3.2 points to 30.0%. Management holds a modest dividend (a flat $0.60 per share annually) and share count is shrinking slightly, so upside from copper flows through to equity rather than being absorbed. Because the three names move with the same metal, the idea is effectively one copper-supply bet expressed three ways — which is…
