Key numbers
over 398 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 0.56, with a hedge ratio of 0.63. Signals from this pair carry more noise than on a tightly linked one.
The spread is at 0.76 standard deviations from its rolling mean, which is effectively at its own norm.
Reversion is slow: the spread needs roughly 47 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 — 45% of the way from the low to the high of the last 398 daily candles.
When this happened before
Divergences over 219 candles: 2. Closed by a return to the norm: 2. The median return took 50 days, the longest one 79 days.
The last closed one ran from 03.06.2026 to 21.08.2026, 79 days: peak z = -4.47, WLD was expensive against STX.
For a holder this answers not “what to do” but “how long it usually took”: the median return is 50 days. That is no guarantee — past divergences closed, this one may not.
| Period | Expensive leg | Peak z | Return |
|---|---|---|---|
| 03.06.2026 — 21.08.2026 | WLD | -4.47 | 79 d |
| 05.05.2026 — 25.05.2026 | STX | 2.65 | 20 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 WLD is 1 STX?
1 STX is worth 0.814583 WLD at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the STX/WLD range?
Over the last 398 daily candles the ratio traded between 0.275833 (17.06.2026) and 1.48562 (05.05.2026).
Are STX and WLD correlated?
The correlation of daily log returns between STX and WLD is 0.56, 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 STX/WLD spread z-score now?
The z-score is 0.76 — 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 STX/WLD suitable for a pair trade?
The mechanics hold up: correlation is 0.56 and the spread historically covers half the way back to its mean in about 47 days. That is a description of past behaviour, not a forecast or a recommendation.
How often do STX and WLD diverge?
Over 219 daily candles the spread left ±2σ 2 times. The median return to the norm took 50 days.
