Key numbers

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 0.60, with a hedge ratio of 0.75. Signals from this pair carry more noise than on a tightly linked one.
The spread currently sits at -4.23 standard deviations from its rolling mean — FIL is cheap relative to ARK by the standards of this window.
Historically the spread covers half the way back to its mean in about 9 days, so a divergence here tends to resolve within weeks rather than months.
The current ratio sits mid-range — 41% of the way from the low to the high of the last 350 daily candles.

Are FIL and ARK correlated?
The correlation of daily log returns between FIL and ARK is 0.60, 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 FIL/ARK spread z-score now?
The z-score is -4.23 — 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 FIL/ARK suitable for a pair trade?
The mechanics hold up: correlation is 0.60 and the spread historically covers half the way back to its mean in about 9 days. That is a description of past behaviour, not a forecast or a recommendation.
