A quién sirve esta entrada — The 1970 book states five principles; the course adds three and completes the canon. Together the eight are the model's constitution — and phasing analysis is their full application on the chart.
Fuente: JM Hurst's Cycles Course (Cyclitec, ≈1973); David Hickson, Hurst's Cyclic Theory in a Nutshell (Sentient Trader). The first five are in the 1970 book — the dedicated entry covers them in full, with Ch. 2's sources.

The book's five principles and the nominal cycles.
The complete canon
| # | Principle | Origin | In one line |
|---|---|---|---|
| 1 | Summation | book (1970) | Price is the sum of all components |
| 2 | Commonality | book (1970) | The same cycles, on nearly every issue |
| 3 | Variation | book (1970) | Durations and amplitudes fluctuate around the nominals |
| 4 | Nominality | book (1970) | The "catalogue" scale of periods (18 years → 5 days) |
| 5 | Proportionality | book (1970) | Amplitude proportional to duration |
| 6 | Harmonicity | course (≈1973) | Adjacent periods sit in simple ratios (×2, ×3) |
| 7 | Synchronicity | course (≈1973) | Lows align in time; peaks do not |
| 8 | Cyclicality | course (≈1973) | The components always exist — even when unseen |
The course's three
6 · Harmonicity
En palabras sencillas — The nominal scale is not a list of arbitrary numbers: each cycle is about double (or triple) the one before. That is why the envelopes nest so well.
Cycle wavelengths are tied by simple harmonic ratios — mostly 2:1, with the odd 3:1. It is the backbone of the nominal cycles table and of envelope nesting — and it echoes the equally spaced lines found in Appendix I.
7 · Synchronicity
En palabras sencillas — The lows of different cycles tend to land together; the peaks slide instead (time translation). That is why all Hurst analysis is built on lows.
Component troughs synchronize in time — Ch. 8's "nest of lows" is the book's operational use of it; peaks can shift (time translation: in uptrends, peaks slide right). It is the principle that makes phasing analysis possible: dating the lows suffices to know the model's state.
8 · Cyclicality
En palabras sencillas — A cycle you "cannot see" is not dead: it is overpowered by a larger component, or its amplitude is in a valley (the magnitude-duration fluctuation). It will be back.
Cyclic components always exist and act, pushing price toward expected highs and lows. Apparent disappearance from the chart has only two known causes: the dominance of a longer cycle, or amplitude temporarily near zero — the documented case of the 28-month sample of 1942–44.
Operational use
- Phasing analysis applies all eight principles at once on the chart.
- The harmonicity constraint disciplines the admissible wavelengths; synchronicity anchors the lows; cyclicality forbids declaring an invisible cycle "dead".
- The tradition's warning: estimating only the recent wavelength without the full model is not enough to trade on.
Summary card
| Element | Value |
|---|---|
| Canon | 5 book principles + 3 course principles = 8 |
| Harmonicity | ×2 (and ×3) ratios between adjacent periods |
| Synchronicity | lows aligned; peaks with time translation |
| Cyclicality | components do not die: they get overpowered |
| Application | phasing analysis (course); nest of lows and cyclic state (book) |
| Source | Cycles Course ≈1973 — not the 1970 book (which has 5) |
