Summary
Conditional paper trade only, on a $100,000 assumed account: buy CPER and sell GLD short after confirmation, and stay flat while entry requirements are incomplete. Copper can outperform if physical tightness persists while higher real yields weaken gold, but the evidence is mixed: ICSG projects refined copper surpluses, Grasberg is recovering, and gold ETF buying hit a record in Q3. A positive expected return has not been established, so the desk sizes small and defines every exit in net dollars.

EXHIBIT 1Trade and economics
Why this trade and why wait
- The case: copper can outperform if physical tightness persists while higher real yields weaken gold.
- Copper is mixed: ICSG projects refined surpluses of 96kt in 2026 and 377kt in 2027; Grasberg is recovering.
- Gold demand pushes back: September ETF inflows were $10bn and Q3 inflows a record $31bn.
- Policy is priced: the Fed range is 3.75% to 4.00%; a widely expected hike alone provides no edge.
When and how
- Entry window: October 15 to November 6, only after two closes with CPER above its 20-session average, GLD below its average, and CPER/GLD above its average.
- Filters: GLD five-session return negative; the latest 10-year real yield above its level five observations earlier; physical copper confirmation; GLD borrow at no more than 2% a year; matched whole-share sizes within 2%.
- Don't chase: skip if the ratio is more than 1.5 standard deviations above its mean.
- Adding: only from October 29, after five sessions, while net P&L is positive and every condition still passes. No averaging down.
EXHIBIT 2Illustrative payoffs at $10,000 per leg
Sensitivities, not forecasts. A +$650 net exit needs a 7.25 percentage point ETF return difference under the $75 cost assumption. Stops cannot guarantee a maximum loss.
Payoff and principal risks
- Tariffs and premiums: CPER retains COMEX tariff and regional premium exposure.
- Both legs can lose: recession, gold demand, borrow recall, gaps and execution failure can hurt both legs.
- Financial, not physical: a relative-value trade informed by physical markets: no cathode cargo, logistics commitment or delivery arbitrage.
- Exits: close both legs at the net dollar exit, on thesis failure, or by January 15, 2027 at 3:30 p.m. ET, using actual liquidation P&L.
