What the numbers say

The legs move together only moderately — correlation of daily log returns is 0.67, with a hedge ratio of 2.00. Signals from this pair carry more noise than on a tightly linked one.

The spread currently sits at 2.92 standard deviations above its rolling mean — RAY is expensive relative to BTC by the standards of this window.

Historically the spread covers half the way back to its mean in about 25 days, so a divergence here tends to resolve within weeks rather than months.

The current ratio sits mid-range — 62% of the way from the low to the high of the last 350 daily candles.
