Key numbers
over 635 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 0.62, with a hedge ratio of 0.20. Signals from this pair carry more noise than on a tightly linked one.
The spread currently sits at 3.15 standard deviations above its rolling mean — BAT is expensive relative to S by the standards of this window.
Reversion is slow: the spread needs roughly 59 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 — 79% of the way from the low to the high of the last 635 daily candles.
Frequently asked
How many S is 1 BAT?
1 BAT is worth 3.4199 S at the latest exchange quotes. The figure is the ratio of the two USDT prices and updates every minute.
What is the BAT/S range?
Over the last 635 daily candles the ratio traded between 0.192727 (21.02.2025) and 4.26782 (26.06.2026).
Are BAT and S correlated?
The correlation of daily log returns between BAT and S is 0.62, 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 BAT/S spread z-score now?
The z-score is 3.15 — 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 BAT/S suitable for a pair trade?
The mechanics hold up: correlation is 0.62 and the spread historically covers half the way back to its mean in about 59 days. That is a description of past behaviour, not a forecast or a recommendation.
