What the numbers say

The legs move together only moderately — correlation of daily log returns is 0.58, with a hedge ratio of 1.29. Signals from this pair carry more noise than on a tightly linked one.

The spread currently sits at -4.80 standard deviations from its rolling mean — SEI is cheap relative to PHA by the standards of this window.

Reversion is slow: the spread needs roughly 61 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 near the bottom of its range — only 0% of the way from the low to the high of the last 363 daily candles.
