Key numbers
over 361 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 closely together — correlation of daily log returns is 0.72. The fitted hedge ratio is 1.48, meaning roughly 1.48 units of ETC exposure balance one unit of ARB.
The spread currently sits at 2.87 standard deviations above its rolling mean — ARB is expensive relative to ETC by the standards of this window.
Reversion is slow: the spread needs roughly 40 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 — 72% of the way from the low to the high of the last 361 daily candles.
