The "Cyclic Principles" introduced by J.M. Hurst in the 1970s are universal, persisting since the dawn of time. Among these, the "Principle of Commonality" stands out, as it demonstrates that the cycles of disparate financial instruments—and, by extension, human activity—are synchronized by a singular, overarching divine force. Troughs of unrelated instruments occur almost simultaneously, while divergences in peaks or amplitudes stem from local or company-specific factors rather than the underlying rhythm.
» The Principle of Commonality assures us that identical specific and forecastable wave processes occur in all negotiable equities of all types on all markets of the world. So all-pervasive is this Principle that it is only the Principle of Variation that prevents the shape of price histories of all equities from being nearly identical. And, as we have seen, it is the interaction of fundamental events and situations with cyclicality, causing wave amplitude change, that is responsible for the Principle of Variation.
» A Commonality Phasing Model is, in effect, a large measuring strip used to preserve wave phase and period information from the analysis of two or more equities. Only the most certain of the wave trough locations are used from any given analysis. As results are added from analysis of more and more equities, gaps are filled in and a commonality distribution range is established for each wave trough position in time. A commonality phasing model can be maintained continuously, thus recording the most definitive evidence of wave phase and period from all analyses conducted. «The Principle of Commonality, J.M. Hurst, 1973.
Hurst emphasized its practical value: understanding one cycle illuminates others, with minor deviations—his third type of the Principle of Variation [each market’s active cycles deviate from the nominal model’s average periods, and these deviations differ across instruments and times]—leaving global synchronization intact as dictated by the Principle of Commonality.
Empirical studies across unrelated assets, commodities, equities, and
economic time series confirm that the Principle of Commonality governs
beyond any single economy, reflecting a universal rhythm and mirroring
humanity’s progression from polytheism toward recognition of a
monotheistic, single guiding influence.
“And your God is one God. There is no deity except Him, the Most Gracious, the Most Merciful.”
The Holy Qur’an, Surah Al-Baqarah (The Cow), 2:163.

The
persistence of cyclical waves through recorded history suggests that
Commonality is trans-historical. Data since around 1000 AD reveal
continuous alignment, and extrapolation indicates these forces existed
long before formal record-keeping. Historical observation supports this:
human advancement in the Stone and Bronze Ages unfolded in temporal
synchrony across disconnected populations, indicating the operation of
the consistent underlying divine force.
neither can they delay it nor can they advance it an hour or a moment.”
The Holy Qur’an, Surah Al-A‘rāf (The Heights), 7:34.
While
troughs—the beginnings and endings of cycles—are closely aligned across
nations, local expression varies. Peaks may occur at different times,
amplitudes differ, and local fundamentals shape trajectories. The
Principle of Commonality thus governs temporal alignment of critical
points while allowing variation in the wave’s characteristics.
Empirical evidence validates these assertions. The Kuznets Swing (an 18-year cycle) peaked in 2006 in Saudi Arabia and in 2019 in the United States, yet both began in March 2003 and bottomed in the global low of March 2020. Minor discrepancies among sub-waves reflect local variation but do not disrupt the synchronization of primary troughs (see chart 1 above).
Chart 2.1: Commodity Price Index and S&P 500, both from 1800 to 2025.
Longer-term studies, including continuous commodity prices and the S&P 500 since 1800, show that over 90 percent of cyclical troughs align temporally across instruments (see charts 2.1 and 2.2 above).

Even unrelated markets, such as soybean prices and the Saudi stock index (Tadawul), demonstrate strong temporal correspondence (chart 3 above). Comparisons of the German DAX and Saudi index (chart 4 above) reveal synchronization across multiple cyclic levels—the 18-month, 54-month (Kitchin), and 9-year (Juglar) waves—further confirming a unifying global force.
in the army of heaven, and among the inhabitants
of the earth: and none can stay His hand,
or say unto Him, What doest
Thou?” The Holy Bible, Daniel 4:35 (KJV).
Hurst’s
Principle of Commonality thus affirms a single, synchronized force
governing the timing of major and minor cycles, while local factors
shape amplitude and peak positions. This robust alignment, persistent
across centuries and diverse instruments, confirms that cyclical
patterns are not random but manifestations of an underlying order.
and the earth? Is there a deity with Allah? Say, ‘Produce your proof, if you should be truthful.’”
The Holy Qur’an, Surah An-Naml (The Ants), 27:64.
Today, we can confidently state that in this article we have presented our proof of a mysterious, dominant, and single force behind almost all fluctuations in human affairs. We can only ask God to grant us wisdom to recognize His design and join us with the righteous after we fulfill our appointed term in harmony with His will.
