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 fitted hedge ratio is negative: over the window ARK and U moved in opposite directions. A pair trade assumes the legs move together, so this combination does not qualify as one.
The spread currently sits at 2.90 standard deviations above its rolling mean — ARK is expensive relative to U by the standards of this window.
Historically the spread covers half the way back to its mean in about 30 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits near the bottom of its range — only 18% of the way from the low to the high of the last 244 daily candles.
Frequently asked
How many U is 1 ARK?
1 ARK is worth 0.143329 U at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the ARK/U range?
Over the last 244 daily candles the ratio traded between 0.0874563 (18.08.2026) and 0.389605 (01.02.2026).
Are ARK and U correlated?
The correlation of daily log returns between ARK and U is -0.13, 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 ARK/U spread z-score now?
The z-score is 2.90 — 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 ARK/U suitable for a pair trade?
No. The fitted hedge ratio is negative, meaning the legs moved in opposite directions over the window — the market-neutral construction that pair trading relies on does not hold here.
