Key numbers
over 244 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 -0.03. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread is at -1.17 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 8 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits mid-range — 43% of the way from the low to the high of the last 244 daily candles.
Frequently asked
How many WLD is 1 U?
1 U is worth 2.56136 WLD at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the U/WLD range?
Over the last 244 daily candles the ratio traded between 1.38429 (17.06.2026) and 4.12448 (18.05.2026).
Are U and WLD correlated?
The correlation of daily log returns between U and WLD is -0.03, 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 U/WLD spread z-score now?
The z-score is -1.17 — 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 U/WLD suitable for a pair trade?
Weakly. Correlation is only -0.03, so the legs do not reliably move together and the spread carries mostly idiosyncratic noise.
