This week’s reading →
753 pairs in seven families, each family weighing the same · correlation of weekly returns, weighted to the last few months (half-life nine weeks), Friday to Friday · a pair breaks when that correlation is two standard deviations away from its own previous two years (Fisher z, spread floored at sampling noise) · Calm, Elevated, High and Severe are the 75th, 90th and 97th percentiles of every week since 2001 · a normal Friday is the median week since 2001 · derived statistics only, no prices · since 1997, recomputed each week, the first published value kept.
