Key numbers
over 399 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 0.39. A spread built on such a weak link reverts by coincidence rather than by mechanism.
The spread currently sits at -2.48 standard deviations from its rolling mean — SOPH is cheap relative to STX by the standards of this window.
The spread has not shown mean reversion over the sample: estimates longer than the available history are discarded rather than reported. Trading this pair on reversion has no statistical footing here.
The current ratio sits near the bottom of its range — only 0% of the way from the low to the high of the last 399 daily candles.
When this happened before
Divergences over 220 candles: 1, and none of them has closed with a return to the norm yet.
One is running right now: it started on 20.08.2026, has lasted 73 days, peak z = -5.44, STX was expensive against SOPH. It has not returned to the norm yet.
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 STX is 1 SOPH?
1 SOPH is worth 0.0044335 STX at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.

Are SOPH and STX correlated?
The correlation of daily log returns between SOPH and STX is 0.39, 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 SOPH/STX spread z-score now?
The z-score is -2.48 — 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 SOPH/STX suitable for a pair trade?
Not on a reversion thesis. The spread has not returned to its mean within the available history, so there is nothing to trade back to.
How often do SOPH and STX diverge?
Over 220 daily candles the spread left ±2σ 1 times, and none of those divergences has closed with a return to the norm yet.
