Cyclic analysis

Cyclic analysis studies recurring market oscillations to measure periods, phases, and operational timing — a complement to trend, not a substitute.

Who it's for — Traders who know trend and indicators but want a time framework: when turns are plausible, how to contextualize entries and exits. It does not replace risk management or volume analysis.

Cyclic analysis assumes prices incorporate recurring oscillationscycles — with recognizable periods and phases, on top of trend and noise. The cyclic analyst's job is to measure, not guess: identify dominant oscillations, their current phase, and how reliably they repeat.

This entry is school-neutral. For J. M. Hurst's historical corpus (1970) and the chapter-by-chapter path → Hurst tradition.


Operational definition

A market cycle is movement that tends to repeat over time with a certain period and amplitude. Practical cyclic analysis targets four steps:

  1. Identify dominant cycles on an instrument or index
  2. Measure period (duration) and amplitude
  3. Determine the current phase (expansion, crest, contraction, trough)
  4. Estimate timing of upcoming turns — always as probability, never certainty

In simple terms — Trend says «where» the market is going; momentum says «how hard»; cyclic analysis says «when a turn is plausible» within measured oscillations.


Why it matters (and what it does not promise)

Contribution Limit
Time framework complementary to trend and volume Does not predict exogenous events (war, default)
Contextualizes entries/exits by phase No tick-level guarantee
Combines with other disciplines Does not replace risk management

Hurst estimates a significant share of price motion is oscillatory and semi-predictable — see Price motion model (Hurst). The rest remains slow trend, shocks, and noise.


Core vocabulary

Concept Role
Period / duration How long one full lap (trough → trough)
Phase Where we are in the lap (toward high or low)
Amplitude How far the oscillation swings
Nesting
Synchronicity Troughs of different cycles aligning — higher turn probability

Chart tools: Curvilinear envelope, Valid trend line (VTL), FLD (post-1970 development).


Relationship to other disciplines

Discipline Question Hub
Cyclic analysis (Hurst) When in time?
Volume analysis (Wyckoff) Who is buying/selling and how hard?
Classical technical analysis Patterns, indicators, structure

Traditions coexist: cyclic confirmation + volume signal + logical stop is integration, not a single «system.»


Suggested study path

  1. Five principles of the Hurst cyclic model
  2. Hurst nominal cycles
  3. Chart pattern verification (Ch. 3)
  4. After the 1970 book: After the book — post-1970 Hurst (FLD, phasing)

Common mistake — Labeling cycles by eye («we're at the 40-week low») without measurement or data verification. Cyclic analysis punishes decorative labeling.
