Measured on daily returns rather than on prices. Two assets that both simply trend upward score near 1.0 on raw prices whether or not they move together, so returns are what answer the question people mean by correlation.
| Metric | BER | ACH |
|---|---|---|
| Max drawdown (400d) | -15.5% | -72.3% |
| Risk-adjusted return (90d) | -0.10 | 0.05 |
| Best 30 days (past year) | — | +62.8% |
| Worst 30 days (past year) | — | -41.8% |
Relative strength over 90 days: BER outperformed ACH by 5.6% — measured on the BER/ACH ratio, so it holds regardless of market direction.
