Key numbers
over 350 daily candles
How each of these is computed: regression spread, hedge ratio, spread z-score, half-life, correlation.
What the numbers say
The legs move closely together — correlation of daily log returns is 0.76. The fitted hedge ratio is 1.06, meaning roughly 1.06 units of SUI exposure balance one unit of ARB.
The spread currently sits at 2.33 standard deviations above its rolling mean — ARB is expensive relative to SUI by the standards of this window.
Reversion is slow: the spread needs roughly 44 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 — 62% of the way from the low to the high of the last 350 daily candles.
Frequently asked
How many SUI is 1 ARB?

Are ARB and SUI correlated?
The correlation of daily log returns between ARB and SUI is 0.76, which counts as a strong 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 ARB/SUI spread z-score now?
The z-score is 2.33 — 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 ARB/SUI suitable for a pair trade?
The mechanics hold up: correlation is 0.76 and the spread historically covers half the way back to its mean in about 44 days. That is a description of past behaviour, not a forecast or a recommendation.
