Key numbers
over 388 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 together only moderately — correlation of daily log returns is 0.52, with a hedge ratio of 1.14. Signals from this pair carry more noise than on a tightly linked one.
The spread is at -1.45 standard deviations from its rolling mean: away from the norm, but not far enough to call it stretched.
Historically the spread covers half the way back to its mean in about 13 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits mid-range — 22% of the way from the low to the high of the last 388 daily candles.
When this happened before
Divergences over 209 candles: 3. Closed by a return to the norm: 2. The median return took 42 days, the longest one 66 days.
The last closed one ran from 28.05.2026 to 02.08.2026, 66 days: peak z = 3.22, AI was expensive against SUI.
One is running right now: it started on 22.09.2026, has lasted 29 days, peak z = -3.47, SUI was expensive against AI. It has not returned to the norm yet.
For a holder this answers not “what to do” but “how long it usually took”: the median return is 42 days. That is no guarantee — past divergences closed, this one may not.
| Period | Expensive leg | Peak z | Return |
|---|---|---|---|
| 28.05.2026 — 02.08.2026 | AI | 3.22 | 66 d |
| 10.05.2026 — 28.05.2026 | SUI | -2.68 | 18 d |
A divergence here is the spread z-score leaving ±2σ; the return is the first value back inside ±0.5σ. Two thresholds rather than one: otherwise chatter right at the border would count as a dozen separate divergences. The first bars of the window are skipped — there z is computed on partial history.
Frequently asked
How many SUI is 1 AI?
1 AI is worth 0.0208694 SUI at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the AI/SUI range?
Over the last 388 daily candles the ratio traded between 0.0154688 (28.09.2026) and 0.0403409 (23.11.2025).
Are AI and SUI correlated?
The correlation of daily log returns between AI and SUI is 0.52, which counts as a moderate 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 AI/SUI spread z-score now?
The z-score is -1.45 — the spread is within its usual range. It measures how far the regression residual log(A) − β·log(B) sits from its rolling mean, in standard deviations.
Is AI/SUI suitable for a pair trade?
The mechanics hold up: correlation is 0.52 and the spread historically covers half the way back to its mean in about 13 days. That is a description of past behaviour, not a forecast or a recommendation.
How often do AI and SUI diverge?
Over 209 daily candles the spread left ±2σ 3 times. The median return to the norm took 42 days.
