Relative strength over 90 days: USD/HKD outperformed USD/CNY by 1.3% — measured on the USD/HKD/USD/CNY ratio, so it holds regardless of market direction.
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.
