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 — the copper story is real, but the trade is not ready and the backtest is a red flag

The idea argues that simultaneous US and Chinese warehouse draws are creating a multi-year copper supply shortage, and Southern Copper's fundamentals give that thesis real credibility — SCCO posted a 60.1% gross margin, 17.4% revenue growth, and a 39.3% return on equity, ranking in the 94th percentile or higher across Materials peers. **But the mechanical execution of that thesis has not worked.** The CPER-based trading rule lost 2.9% over 60 months with a 47.9% win rate, and the walk-forward validation produced zero profitable in-sample folds across three segments. The research team tested four parameter variants and none cleared the bar for live deployment — the final status is explicitly "no recommendation." Even the most promising candidate, which lowered the RSI entry threshold from 40 to 36 and managed two positive folds in-sample, still did not beat the baseline by the required margin in the untouched holdout. Worse, FCX's revenue was essentially flat at 0.07% year over year, which undercuts the idea's claim that a shortage is already biting into miner top lines. The setup is not actionable today regardless: CPER's RSI sits at 58.0, far above the 40-point entry ceiling, and price is $1.49 above the 50-day average at $38.59. The bull case lives in the miners' fundamentals; the backtest does not validate the trade. **Conviction breakdown:** Thesis support scores moderately (65) because SCCO's metrics genuinely confirm a supply-driven pricing environment, but FCX's flat revenue tempers the urgency. Trade readiness is very low (15) — neither the RSI nor the price condition is close to triggering, and no robust parameter setup was recommended. Risk quality is fair (50) given the 2% stop and 4% take-profit framework, though daily-bar exit fills may overstate quality. Backtest evidence is the weakest link (20) — a negative full-cycle return with no profitable walk-forward folds is a serious red flag. Fundamentals trend scores well (75) for SCCO specifically, with margins, growth, and returns all elite.

Trade now

**Entry status: Not yet — two conditions unmet.** CPER closed at $40.08, trading above its 50-day average ($38.59). The strategy requires price at or below that line, which puts it roughly $1.49 away (about 3.7%). More critically, RSI (14) sits at 58.0 — well above the entry ceiling of 40. That is a 18-point gap, meaning the strategy is looking for a meaningful pullback before it will consider buying. The idea's bullish thesis on simultaneous US–China copper demand does not change the rule set: the system waits for a dip, not a breakout. **What "wait" means concretely.** Do nothing on CPER today. A valid setup would require a decline of at least $1.49 to bring price to the 50-day moving average, coupled with an RSI reading under 40 but above 20 — i.e., a pullback that is sharp enough to reset momentum but not so severe that it signals a trend break. If copper continues straight up on the supply-shortage narrative described in the thesis, this rule set will stay on the sidelines. **Risk parameters if triggered.** The stop-loss hierarchy is explicit: a hard 2.0% stop on any position, a take-profit at 4.0%, and a structural stop below support at $38.05 (rank 2). That yields an effective reward-to-risk of roughly 2:1 on the percentage-based exits. The nearest resistance-based profit target sits at $39.91, which is actually below the current price — meaning the resistance-level exit is unlikely to bind on a fresh entry and the 4.0% take-profit becomes the operative upside cap. **Backtest context.** The completed 60-month backtest produced 117 trades with a 47.9% win rate and a maximum drawdown of 7.34%. The more recent 24-month window was tighter: 33 trades, a 57.6% win rate, and just a 1.03% drawdown. No parameter variant improved on the baseline by the required margin, so the frozen configuration stands.

Why the copper miners backing this thesis look fundamentally ready

The idea argues that a simultaneous physical draw on copper from both the US and China is creating a genuine supply shortage that will take years to resolve. Southern Copper's fundamentals give that thesis its strongest empirical anchor. SCCO posted a 60.1% gross margin and a 52.2% operating margin in its latest full-year snapshot, placing it in the 94th and 97th percentile of Materials peers, respectively. Revenue grew 17.4% year over year, and free cash flow reached $3.43 billion — enough to self-fund expansion without relying on external capital. A return on equity of 39.3% ranks in the 96th percentile. These are not speculative numbers; they describe a company already converting higher copper…
