What the numbers say

The legs move together only moderately — correlation of daily log returns is 0.41, with a hedge ratio of 0.46. Signals from this pair carry more noise than on a tightly linked one.

The spread is at 1.34 standard deviations from its rolling mean: away from the norm, but not far enough to call it stretched.

Reversion is slow: the spread needs roughly 52 days to cover half the way back to its mean. A position would have to be held for a long time.

The current ratio sits mid-range — 54% of the way from the low to the high of the last 360 daily candles.
