Is the ground moving? Tremor Watch in a minute and a half.
A seismograph can’t tell you when the next earthquake will come; it tells you whether the ground is moving. Tremor Watch does that for markets, whose ground is their relationships: every week it counts the ones that stopped behaving like their own past two years, with a reading for every week since 1997.
1 min 26 s · in English, with captions · The pictures are illustrations; the index since 1997 is the real reading · Descriptive, not a forecast.
This is the reading for the week ending 6 November 2026, kept as first published.
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.
