Key numbers
over 312 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 ASTER and BANK 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 2.09 standard deviations above its rolling mean — ASTER is expensive relative to BANK by the standards of this window.
Historically the spread covers half the way back to its mean in about 19 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits mid-range — 75% of the way from the low to the high of the last 312 daily candles.

Are ASTER and BANK correlated?

What is the ASTER/BANK spread z-score now?
The z-score is 2.09 — 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 ASTER/BANK 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.
