Cyclic theory

Hurst cyclic analysis theory: price model, principles and empirical foundations.

On this page

Theory of cyclic analysis applied to markets: how Hurst (and others) model price, which principles govern the model, why cycles repeat.

Menu → Market Cycles → Cyclic theory — Here you build the «why» and the model. Technical terms live in glossario; operational techniques under Market Cycles → Methodologies. If you do not know buy, timeframe, or trend, start at concetti.


Encyclopedia — where foundations sit

Level Hub Typical question
1 concetti What does «cycle» mean in general?
2 Foundations ← you are here How does Hurst decompose price?
3 glossario What does «envelope» or «MD fluctuation» mean?
4 trader Who wrote all this?

From theory to practice: Market Cycles → tradizione-hurst (book path) → metodologie (techniques by phase).


Prerequisite — Chapter 1 in tradizione-hurst: operating philosophy, compounding, four pillars. Then return here for the theoretical core.
