There are important differences in the nature of the declines. The current series looks like a bear market in the form of 1973-4 whereas 1929-32 was much more precipitous. This may be attributed to the extraordinary actions of the FED and Treasury. However, this may only soften the blow and not the outcome, most likely adjusted for inflation.
The Intraday Volatility matches up nicely so far as we have aligned them Peak to Peak without regard to pricing. It will be in the market action going forward where the model will be assessed here.
"Some people see God as they see a cow, and love Him as they love a cow — for the milk and cheese, and the profit it brings. This is how it is with people who love God for the sake of worldly possessions or inward comfort. They do not truly love God when they love Him for their own advantage. The eye through which I see God is the same eye through which God sees me; my eye and God's eye are one eye — one seeing, one knowing, one love.”
Meister Eckhart, Predigten und Traktate
