Copper is approaching record highs because both the US and China are aggressively pulling physical metal out of warehouses at the same time, creating a genuine supply shortage. While most headlines focus on tech and AI, this quiet bidding war means anyone

Verdict: wait for the pullback-reclaim setup

The copper-scarcity thesis has genuine fundamental teeth — Southern Copper's 60.1% gross margin (94th percentile) and 17.4% revenue growth demonstrate that at least one miner is already converting higher prices into profit, and Bloomberg-cited inventory draws support the supply-side narrative. Against that, Freeport-McMoRan's essentially flat 0.07% revenue growth (29th percentile) is a conspicuous weak spot that suggests the squeeze has not yet fully flowed through to realized contract pricing, and the CPER backtest is too thin — four trades at a 50% win rate and 0.61% over five years — to confirm the entry framework works reliably. Critically, the strategy's own entry conditions are not live: the setup requires an uptrend-pullback-reclaim structure, but CPER is currently extended above its moving averages rather than pulling back, and the 50-day EMA is above the 200-day EMA rather than below as the rules specify. **Conviction breakdown:** Thesis support scores well at 72, reflecting the strong SCCO fundamentals and the macro narrative. Fundamentals trend earns 60, pulled lower by FCX's flat revenue and negative Q1 free cash flow. Risk quality is moderate at 55 given CPER's deeply negative skewness and the approximate stop fills. Backtest evidence is weak at 35 — the sample size is too small and returns too modest to distinguish skill from luck. Trade readiness is also low at 35 because the entry rules are not triggered and the current setup looks like momentum, not the pullback the strategy is built to catch.

Trade now

The strategy's four entry conditions on CPER are partially in place but two remain unresolved. RSI (14) sits at 58.0, comfortably above the 40 threshold — that condition is met. The stochastic crossover is near trigger, essentially at the crossing point now. But the 50-day EMA needs to be *below* the 200-day EMA for this to qualify as an uptrend-pullback setup, and right now the 50-day EMA is at 38.80 versus the 200-day at 36.15 — the 50-day is 2.66 points above the 200-day, not below. That is a structural mismatch the thesis has not yet reconciled. The second open condition is a price cross back above the 50-day EMA. CPER closed most recently at 40.08, already 1.27 points above the 50-day EMA at 38.80, so this one is near but not yet confirmed as a fresh cross. Combined, the setup is asking for a mean-reversion dip: the 50-day EMA would need to fall below the 200-day EMA (or the rules need to catch a moment where that ordering has just flipped), and then price needs to reclaim the 50-day from below. At current prices, CPER is above both moving averages and above the Bollinger upper band at 39.29, so the market is extended rather than pulling back. The exit framework tells you the risk shape if a trade eventually triggers. The stop-loss is a close below the 50-day EMA — at today's 38.80 level, that would mean roughly a 3.2% decline from the current 40.08 close. The signal exit requires RSI above 70, price above the upper Bollinger band, and 60 bars elapsed — with RSI at 58.0 and price already above Bollinger, two of three exit conditions are closer to active than the entry is. The backtest covering 60 months produced four trades with a 50% win rate, a 0.61% return, and a maximum drawdown of 1.52%; the 24-month sub-window saw two trades at a 100% win rate and a 3.43% return with a 4.45% drawdown. No parameter-sensitivity recommendation was established — the evaluation exceeded its time budget, so no nearby-parameter variant is being applied. "Wait" means concretely: do not enter today. CPER needs to either dip toward or below the 50-day EMA and then reclaim it, and the 50-day/200-day EMA relationship needs to align with the pullback-reclaim logic the strategy is built around. Right now the metal is trending above its moving averages with RSI in the upper-50s — a momentum environment, not the pullback environment this rule set is designed to catch.

Why the supply-squeeze bull case has real numbers behind it

The idea's core claim — that a simultaneous US-China scramble for physical copper is driving prices toward records — is supported by concrete fundamental leverage in the mining companies involved. Per the Bloomberg pieces on August 7, copper is heading for record closes in London as both the US and China squeeze available buffers, tightening the global market. For investors in the miners, the question is whether they have the margin structure to convert higher copper prices directly into…
