Three times before. Friday by Friday, from the week each one crossed.
Fear is normal. Participation has been narrow since 16 Oct.
More than in 79 of 100 Fridays since 2010. Last week: normal.
Fewer shares taking part than in 81 of 100 Fridays since 2010. Last week: narrow.
Fridays since 2010 with fear above normal and participation narrow. Last time: 9 May 2025.
The Tremor index stands at 4.0× a normal Friday, High. Relationships are breaking while fear is not priced in.
Fear: realised volatility of US shares and credit spreads. Participation: the share of US stocks above their 200-day average, advances against declines, and the index within its own year’s range. Each is measured against its own past. Derived statistics only, no prices. Descriptive, not a forecast.

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 13 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.
