Relative strength over 90 days: SOL outperformed ETH by 2.5% — measured on the ETH/SOL 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.
