What we don’t trade, but study for warnings about what the 19th Century called “slumps”, from Stefan Jovanovich
August 29, 2025 |
Our FO has been using Grok3 to build tables of the historical declines for financial assets. I have been doing the typing of the queries, Grok has done the thinking and the other members of the FO have set the definition for the market measure they want to use for timing. The measure is what our most smart ass member calls the Louis L'Amour "herd size" - the notional value of the assets wandering around the range.
Here is the data for the 10 worst quarter-to-quarter/year-to-year period slumps in the S&P 500 options herd size for which Grok was able to retrieve reported data.
