Key numbers
over 374 daily candles
How each of these is computed: regression spread, hedge ratio, spread z-score, half-life, correlation.
What the numbers say
The legs barely move together: correlation of daily log returns is only 0.28. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread currently sits at 2.25 standard deviations above its rolling mean — RAY is expensive relative to ACE by the standards of this window.
Reversion is slow: the spread needs roughly 34 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 in the upper part of its range — 100% of the way from the low to the high of the last 374 daily candles.

Are RAY and ACE correlated?
The correlation of daily log returns between RAY and ACE is 0.28, which counts as a weak link. Log returns are used rather than prices: two rising assets correlate almost by default, joint day-to-day movement is what matters.
What is the RAY/ACE spread z-score now?
The z-score is 2.25 — the spread is stretched beyond two standard deviations. It measures how far the regression residual log(A) − β·log(B) sits from its rolling mean, in standard deviations.
Is RAY/ACE suitable for a pair trade?
Weakly. Correlation is only 0.28, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
