"Space-Time Forecasting of Economic Trends" | Muriel and Louis Hasbrouck

The Space-Time Structure, pioneered by the multidisciplinary partnership of Muriel and Louis Hasbrouck, functions as a sophisticated theoretical framework that interprets economic fluctuations through natural wave patterns and solar-electromagnetic forces. Muriel Elizabeth Bruce Hasbrouck (1890-1981), a Canadian scholar of comparative philosophy, intellectually shaped by Walter Russell's cosmogony, and author of the personality study "Pursuit of Destiny," provided the foundational insight into human behavior. 

 

Each 35.8-year cyclic wave from C crest to C crest is divided into 12 periods, covering about 3 years each (2.983 years, 35.796 months, or 1,089.51 days). The C to D period represents uncertainty and fear (as in 1930–1933). D to E brings temporary recovery (as in 1936). F to G is a time of reconstruction wherein psychological factors of the new trend appear (as in 1940–1953). From G, the pull from the peak ahead at C is clearly evident. Minor adjustments at A and B often are misread as threatening a depression (as in 1957 and 1962).

Her 1940 discovery, co-developed with her husband Abraham Louis M. Hasbrouck (1890-1979), established a predictive index for timing radio transmission disturbances—initially tested with Bell Telephone Laboratories—which later expanded to forecast earthquakes, volcanic eruptions, solar flares, and even missile launch failures in the early 1960s. They changed tracks when Louis noticed that many of the dates that Muriel generated coincided with stock market moves. Their scientific rigor was balanced by Louis, a Yale-educated Canadian World War I pilot and World War II officer with a deep background in finance. Having mastered investment at Bonbright and Company before becoming an independent counsel, Louis dedicated himself from 1930 onward to uncovering the natural laws underlying market fluctuations and shifting economic trends.  

 » Economically, it is a WAVE PATTERN of changing trends in collective instinct. «

 

Together, they conceptualized the universe as operating via rhythmic energy waves that constitute a persistent "Field" surrounding Earth. This field is continuously modulated by solar activity, planetary movements, and geomagnetic disturbances, creating a "wave pattern in time" that evokes biological and psychological responses in all living entities. Unlike mechanical or deterministic models, these waves do not repeat in identical cycles; rather, each represents a unique evolutionary progression within natural and human systems. Louis and Muriel Hasbrouck’s Space-Time Forecasting is a long-range economic and market forecasting system based on the premise that future conditions influence the present, rather than markets being driven solely by past data. 

 

The system holds that the Sun is a pulsating electromagnetic source whose energy radiates rhythmically through space, forming a dominant 35.8-year wave with embedded subcycles—most notably a nine-year rhythm divided into building, peak, and declining phases corresponding to economic expansion, inflation, and contraction. Planetary bodies do not cause events directly and are not interpreted symbolically; instead, their electromagnetic fields modulate and channel the solar field, altering the timing and intensity of energy reaching Earth. These interactions generate wave-like disturbances that affect all terrestrial systems, including collective human psychology.

Space-Time Trend Waves represent the changing flow of human energy and motivation at the socio-economic level. Each Wave follows an orderly, recognizable course from one peak of prosperity (C) to the next in about 36 years. Each Wave is divided into 12 interim phases averaging 3 years each, which can be qualitatively evaluated.

 Legend:

C Wave Crest, Prosperity Peak, followed by REVERSAL to D.
D to E Temporary Recovery.
F to G Start of rise toward next peak, with intimations of qualities of the new, incoming trend (as from 1941 to 1953).
G Activation of new trend toward next peak C.
A & B Minor interruptions of upward trend (as in 1957 and 1962).
C Wave Crest, Prosperity Peak.

History shows that during the reversal of trend following each Wave crest (C) new attitudes develop—social, political, and economic. This, as the Space-Time Structure of History reveals, is an important key to the evolution of civilization. Not only history, but modern science today substantiates the application of the Space-Time Structure as a unified field involving a natural linkage between space, time, and human behaviour. A "new hypothesis" in physics declares that such a linkage exists, that the mind of man and the wave properties of the electron are two extremes of the same thing, and that the "wave of the future" can be perceived in the evolutionary structure of the field.

Human behavior, mass sentiment, and markets are treated as electrical systems embedded within this solar-planetary field, making financial markets sensitive indicators of underlying energetic conditions. The Hasbroucks do not predict specific events or prices; they forecast conditions—states of economic pressure, instability, or expansion—analogous to weather forecasting, with events arising only when conditions reach critical thresholds. 

 

Time and space are considered inseparable, and the Space-Time Wave is visualized as a trend-like heartbeat whose expansions, contractions, and inflection points signal systemic transitions such as monetary regime changes. The system is presented as a bridge between electromagnetic field theory and empirical economic pattern recognition, rejecting traditional astrology and claiming validation solely through long-term forecasting consistency rather than short-term speculation.

The 35.8-year Saturn-Neptune cycle exactly matches the crest-to-crest Hasbrouck cycle.

In practical application, the structure identifies predictable cycles—often spanning approximately 35.8 years between peaks—which are further segmented into twelve distinct periods labeled A through G. These phases allow for the identification of critical turning points, such as the 1929 crash or mid-1960s economic shifts, serving as an early warning system for socio-economic disruptions.

 

Despite its predictive nature, the framework rejects fatalism, viewing each wave as a "new adventure" for human advancement rather than an inevitable repetition. By blending elements of physics, psychology, and investment finance, the Space-Time Structure offers a holistic methodology for navigating perpetual change, providing a roadmap for decision-making in finance, policy, and personal strategy.

 

 Muriel and Louis Hasbrouck, 1976.

 

Based on the structure of the 35.8-year Hasbrouck cycle, which spans from one prosperity crest (point C) to the next and is divided into 12 periods of approximately 2.983 years each, the period from early 2026 to around 2037 (around the maximum of solar cycle 26) corresponds to the latter stages of the current cycle commencing at the 2001 crest (around the maximum of solar cycle 23).

Drawing from historical analogies (e.g., the 1929–1965 cycle), this timeframe aligns with the transition from reconstruction to the final upward phases leading to the projected 2037 crest. The phases are characterized below in approximate 3- to 5-year segments, reflecting grouped periods with their economic and psychological attributes:

■ 2026–2029 (G to A phase, continuation of upward trend): This segment follows the activation point (G, around 2025), marking the sustained initiation of a new upward economic trajectory. It is characterized by strengthening trends, emerging optimism, and progressive recovery from prior reconstruction, with psychological factors fostering confidence and innovation toward the next peak.
■ 2029 (A, minor interruption): A brief adjustment period interrupting the upward momentum, akin to historical pauses (e.g., 1957). It involves temporary setbacks, increased caution, or minor economic corrections, driven by psychological shifts toward reevaluation without derailing the overall ascent.
■ 2029–2034 (A to B phase, further progression): Building on the prior interruption, this phase entails continued advancement with incremental adjustments. Economic growth resumes with refined strategies, supported by adaptive psychological responses that emphasize stability and gradual expansion amid evolving trends.
■ 2034 (B, second minor interruption): Similar to the first interruption but later in the cycle (e.g., analogous to 1962), this involves another short-term disruption. It features heightened uncertainty or corrective measures, with psychological elements promoting resilience and preparation for the final push.
■ 2034–2037 (B to C phase, final lead to crest): The concluding segment propels toward the prosperity crest (C, around 2037). It is defined by accelerating upward momentum, culminating in peak prosperity, with psychological drivers of enthusiasm and anticipation facilitating robust economic expansion and trend fulfillment.

My Conversion to Heliocentric Financial Astrology | Malcolm G. Bucholtz

The year 2025 marked a pivotal turning point in my professional journey. When I was first introduced to astrology at the 2012 United Astrology Conference (UAC) in New Orleans, the presentations centered exclusively on geocentric astrology. This approach emphasized planets in signs and houses, retrograde motions, and the purported influence of distant bodies such as Pluto (with its 248-year orbital period), Neptune, and Uranus—even in the context of financial astrology. I accepted these ideas without reservation, as they represented the prevailing consensus among attendees and appeared to be the only legitimate framework.

S&P 500 vs. 225-day orbital and 243-day axial spin cycles of Venus: April 2025 lows marked conclusion of spin cycle; midpoint of orbital cycle closely coincided with October 30 highs; December downturn occurred at termination of spin cycle.

Over the ensuing years, I authered books, conducted extensive research, and published newsletters, all rooted in this geocentric perspective. Nevertheless, persistent doubts gradually surfaced: an inner voice highlighted the methods’ inconsistent outcomes. Though I initially disregarded these misgivings, they became impossible to ignore by 2025. Deeper scientific literature portrays the solar system as a vast resonance machine: finely balanced and harmonically interdependent, such that altering the motion of any single planet would destabilize the entire structure. As inhabitants of Earth, humans are inherently attuned to these cosmic rhythms—whether consciously or not—and this attunement manifests emotionally in collective market behavior reflected on price charts.

 

I eventually uncovered papers by astronomers and mathematicians who, operating outside mainstream consensus, attribute phenomena such as climate change to celestial influences rather than human activity. When integrated with findings from medical journals, their work offered profound insight. These researchers maintain that only five planets warrant attention: Mercury, Venus, Earth, Jupiter, and Saturn. Distant bodies like Pluto and Uranus can be disregarded owing to their negligible effects.

Earth’s 23.4° axial tilt fosters seasonal stability; 

Uranus’s 97.8° tilt "sideways" obliquity.

 

Jupiter and Saturn, by virtue of their immense mass, join the inner planets in exerting gravitational forces on the Sun’s surface during precise angular alignments. Such configurations prompt increased solar radiation in the form of sunspots; although Earth’s magnetic field deflects a portion of this energy, a substantial amount reaches the surface. Medical research connects this phenomenon to the "sodium-potassium pump model", discovered in 1957 by Jens Christian Skou. This model elucidates cellular responses, whereby influxes of solar energy trigger biochemical cascades that heighten susceptibility to emotional shifts correlated with variations in solar emissions.

Most financial instruments frequently align with multiples or fractions of Mercury’s and Venus’s orbital and rotational periods.

 

I observed that major heliocentric alignments involving Mercury, Venus, Earth, Jupiter, and Saturn consistently coincide with increased volatility or trend reversals across various assets, including the S&P 500, gold, coffee, orange juice, wheat, corn, oil, and cocoa. Although directional outcomes differ—some bullish, others bearish, and some leading to sideways consolidation—the effects are reliable when correlating heliocentric planetary positions with price charts. This pattern can be attributed to solar emissions influencing human emotion through cellular chemistry. 

In preparing the "Financial Astrology Almanac 2026", I employed the periodogram function—a mathematical tool for time-series analysis—to detect dominant cycles in price data. Nearly all examined financial instruments exhibit cycles that frequently align with multiples or fractions of Mercury’s periods (88-day orbit; 58.65-day rotation) and Venus’s periods (225-day orbit; 243-day rotation).

Helioeconomics: Solar Cycles & World Economic Rhythms | Aleksander Valkov

In his June 2025 working paper, Russian economist Aleksander Valkov, Head of the Department of National and World Economy at Moscow State University, introduces "helioeconomic theory"—a bold interdisciplinary framework asserting that long-term solar activity, specifically the approximately 11-year Schwabe sunspot cycle (measured via Wolf sunspot numbers), serves as a primary exogenous driver synchronizing global economic cycles across centuries and countries. 

HelioEconomic Leading Index (HELI) and Economic Cycles (1750–1900). 

 

HelioEconomic Leading Index (HELI) and Economic Cycles (1900-2050): 

Blue line: HELI Index (normalized, 0–1 scale); Black dashed line: Solar Cycle (Wolf number, 11-year harmonic); Red vertical dashed lines: Economic Peaks (1749, 1801, 1859, 1917, 1968, 2024); Green vertical dashed lines: Economic Bottoms (1775, 1833, 1889, 1944, 1996, 2045); X-axis: Years 1750-1900 and Years 1900-2050, in strict chronological order.

 

HelioEconomic Leading Index (HELI) for USA, Russia, China, and Great Britain (1900-2024).

Blue line: USA; Red line: Rusia; Green line: China; Brown line: Great Britain; Red vertical dashed line: Economic Peak; Green vertical dashed line: Economic Bottom. 

 

Rather than viewing economic expansions and contractions as purely the result of credit, technology, policy, or random shocks, Valkov argues that solar magnetic activity provides the underlying rhythm. He posits that every fifth solar maximum plants the seed for a major economic peak approximately five to ten years later, while solar minima trigger the deepest troughs. 

 

This pattern establishes a dominant approximately 55-year supercycle (roughly five Schwabe cycles) that has governed global economic turning points from pre-industrial 1750 through the industrial and modern eras, spanning diverse economies including the USA, UK, Russia, China on a panel of 12 major countries.

 

 

» These findings have important implications for economic theory, forecasting, and policy. «

 Next solar minimum (Cycle 25/26 transition) anticipated around 2030–2031.

 

Valkov posits that solar activity influences economies through four interconnected channels: 

 

The first channel involves biophysical and health effects: geomagnetic storms and solar radiation variations are argued to affect human health, melatonin levels, mood, and cognitive function, citing medical literature on increased depression, suicides, and risk aversion during periods of high solar activity. 

Second, technological disruptions are a growing concern in the modern era, as space weather impacts infrastructure, satellites, and power grids. 

Third, Valkov includes agricultural and climate channels through subtle influences on weather patterns and crop yields, though he acknowledges this is a weaker driver for the regular 11-year solar cycle. 

Finally, the psychological and behavioral channel is considered crucial, suggesting that collective mood shifts drive investor sentiment, risk-taking, and economic decisions, a concept that builds on research by Krivelyova and Cesare Robotti (2003) and similar studies. 

 

The key innovation of Valkov's work, however, is the proposed 55-year rhythm: every fifth solar maximum (a period of 54–60 years) marks a "super-peak" corresponding to major economic booms and the subsequent crises that occur when the underlying expansion ultimately overshoots.

Valkov's theory builds on earlier ideas from Jevons (1875), Chizhevsky (1924), Garcia-Mata (1934), and the Foundation for the Study of Cycles, but he elevates them with rigorous modern statistical methods and an extraordinary historical dataset covering twelve major economies, including the United States, United Kingdom, Russia, and China—both before and after industrialization.

 » The HELI index outperforms traditional leading indicators in predicting major economic turning points, offering

policymakers and analysts a new interdisciplinary tool for risk assessment and macroeconomic planning. « 

At the heart of Valkov's paper is the HelioEconomic Leading Index (HELI), a composite indicator that combines smoothed Wolf sunspot numbers (inverted and appropriately lagged) with macroeconomic variables such as unemployment rates, GDP growth, and industrial production. Spectral analysis, Granger causality tests, and principal component methods show that the HELI index explains approximately 78% of the variance in global business-cycle turning points over nearly three centuries—a level of explanatory power rarely achieved by conventional leading indicators.

The alignment is striking: Major economic peaks repeatedly occur near every fifth solar maximum (for example, the Roaring Twenties, the mid-1960s–early-1970s boom, and the 2014–2020 expansion), while the deepest depressions and recessions cluster around prolonged solar minima (the 1930s Great Depression, the early 1980s double-dip, and the 2008–2009 Global Financial Crisis all fit the pattern with remarkable precision).

The 11-year solar cycle is historically segmented into four distinct periods based on psychological excitability: Minimum (3 years), Growth (2 years), Maximum (3 years), and Decline (3 years).

» In each century, the universal cycle of historical events is repeated exactly 9 times. Throughout the world history of Mankind, beginning with 500 B.C. and until the present time, in each century I have discovered 9 clearly outlined concentrations of the initial moments of historical events. Thus, it can be considered that each cycle of the general historical, military or social activity of humanity is equal, on average, to 11 years. « 

Alexander L. Chizhevsky, 1924.

Valkov's long-term charts overlaying sunspot numbers with unemployment or industrial production in the US, UK, Russia, and China reveal an almost eerie synchronization that persists through wars, pandemics, gold standards, fiat currencies, and radically different political systems. Given that Solar Cycle 25 reached a stronger-than-expected maximum around 2024–2025, the HELI index indicates that the current global expansion has already peaked or is in its final stage.

  

» On average, the difference between the peaks and troughs of solar activity and economic cycles does not exceed six months. «

88% of recessions since the 1800s and 100% of major financial crises occurred during the downturn of sunspot cycles. 

Leonty Miroshnichenko, 2023.

 

The model forecasts an accelerating contraction phase leading into a major multicycle trough centered on the early 2030s—precisely the period when the next solar minimum is expected. Mainstream macroeconomics remains deeply skeptical of any strong exogenous pacemaker for business cycles, and critics will rightly point to risks of overfitting and the indirect nature of causal mechanisms. 

 

Yet, the sheer scope of the evidence—280 years, twelve diverse economies, consistent performance across radically different institutional regimes—makes the paper impossible to dismiss lightly. Whether helioeconomics ultimately gains broad acceptance or remains a heterodox curiosity, the HELI index has already demonstrated superior long-range forecasting ability compared with traditional indicators.

Heliocentric Planetary Events and Financial Markets | Malcolm G. Bucholtz

The research of astronomers and physicists such as Nicola Scafetta (Italy), Roger Tattersall (UK), and Ian R. G. Wilson (Australia) suggests that gravitational torque exerted by planetary alignments on the Sun’s plasma layers modulates solar radiation. These torques intensify when heliocentric planetary aspects align at 0°, 90°, 120°, and 180°. The Sun, as a fluid-like sphere of plasma, responds dynamically, torque destabilizes its equilibrium and amplifies radiative output.

Primarily, the orbits of Mercury, Venus, Earth, Jupiter, and Saturn drive the Sun’s motion around the solar system’s center of mass (CM) and generate torques on its outer plasma layers, corresponding to numerous cycles observed on Earth.

This excess quantum energy propagates outward, penetrates Earth’s geomagnetic shield, and interacts with the human brain at the neuronal level. Microscopic receptors in nerve cells appear sensitive to such quantum fluctuations, giving rise to what we recognize as emotion. Collective emotion or mood, in turn, governs social behavior: positive affect fosters risk-seeking, bullish dynamics in financial markets, while fear induces risk-aversion and bearish trends. Thus, planetary configurations that heighten solar emissions manifest indirectly as systematic shifts in the sentiment of financial market participants.

■ Nicola Scafetta, a physicist and climate scientist at the University of Naples Federico II, has published extensively on how planetary harmonics synchronize with solar and climate oscillations. His semi-empirical models demonstrate that cycles linked to Mercury, Venus, Earth, Jupiter, and Saturn correspond with variations in solar activity and, by extension, climate patterns. He has argued that planetary–solar resonances are physically meaningful and statistically coherent, particularly at 20-year, 60-year, and longer-term cycles.

■ Ian R. G. Wilson, an independent academic researcher, in turn, has investigated how periodic peaks in planetary tidal forces and spin–orbit coupling may modulate the solar cycle. His work emphasizes that alignments involving Venus, Jupiter, and Saturn can amplify tidal torques on the Sun, coinciding with observed sunspot cycle minima and maxima.

■ Roger Tattersall has developed a complementary framework, treating the solar system as a resonant harmonic structure, where orbital interactions impose rhythmic signals on solar activity. He contends that planetary motion imprints resonant frequencies on both solar variability and long climate records, underscoring the systemic coherence of planetary–solar–terrestrial dynamics.

 

To illustrate their findings and central theses, I have prepared three charts showing how planetary alignments from May through September 2025 coincided with pronounced market reversals or periods of consolidation:

Gold futures (daily candles), May to September 2025.

McGrath Rentals (daily candles), May to September 2025.

Coinbase (daily candles), May to September 2025.

Heliocentric Venus 120° Saturn, Mercury 180° Saturn, and Jupiter 90° Saturn in mid-May coincided with a sudden V-bottom in gold futures; with a sideways consolidation in McGrath Rentals; and with a pause in the bullish advance of Coinbase. Later, Mercury at maximum latitude in June produced equally dramatic, but instrument-specific, emotional inflections — bullish surges, reversals, and runaway trends, depending on context. July’s Mercury latitude minimum similarly aligned with abrupt tops or bottoms, again varying across assets but consistent in provoking emotional discontinuity.

Across unrelated markets — gold futures, a construction-rental equity, and a cryptocurrency exchange — the same heliocentric triggers elicited measurable shifts in human behavior. This convergence confirms that planetary-solar mechanics, as articulated by Scafetta, Wilson, and Tattersall, are not abstract correlations but active influences on human sentiment and decision-making.

My focus therefore moves beyond classical astrology, with its symbolic houses and signs, toward a physics-based heliocentric framework. The question is no longer what Mars ‘means’ in Aries, but how concrete planetary alignments exert torque on the Sun, modulate solar emissions, and reverberate through human neurobiology into collective market psychology.

How to Divide the Yearly Time Period | W.D. Gann

The average of stocks and many of the individual stocks make important bottoms and tops according to the Seasonal Changes, which are as follows:

The Winter Quarter begins December 22nd, and 15 days from this date is January 5th and 6th, which are always important dates to watch at the beginning of each year, as stocks often make extreme high or extreme low around these dates and a change in trend takes place. 

 

According to Kepler's Second Law, the line connecting the Earth and the Sun sweeps out equal areas in equal times,

causing the Earth to move faster when closer to the Sun and slower when farther away (Law of Equal Areas).

Adding 180 solar degrees to the major low in US stocks on April 7 (Mon) points to a high on October 6 (Mon). 

When stocks make low in December, just before or just after the 22nd, a January rise usually follows. Dividends are paid on the first of January, and people buy for the dividends, which brings about a rally which often culminates around the 3rd to 7th. However, in some years, the January advance lasts until around the 20th to 21st.

■ February 5th is 45 days from December 22nd, and minor changes often take place around this date and, sometimes, very important tops and bottoms are reached.
■ March 21st is 90 days from December 22nd. This is the date when the Sun crosses the equator and Spring begins. The Spring rally in the stock market often starts around this date or culminates if stocks have been advancing previous to this date.
■ May 6th is 46 days from March 21st or 135 days from December 22nd and equals the 135° angle. Watch for important change in trend around this date.
■ June 22nd is 93 days from March 21st, which equals 90°, and, of course, it is opposite December 22nd and is important for seasonal change, as Summer begins at this date.
■ July 7th is 15 days from June 22nd and six months or 180 days from January 7th. July being a dividend month, advances or declines often culminates around this date, and an important change in trend often takes place. It is the next important date to watch after June 22nd.
■  August 8th is 47 days from June 22nd, but the Sun has only moved 45°, which equals the 45° angle. This is a very important date for change in trend, and you should watch stocks that make tops and bottoms around this date.
■ September 23rd is 93 days from June 22nd, but the Earth or Sun has only travel 90°. The Sun crosses the equator at this time and is 180° or opposite the point where it crosses the equator on March 21st. Fall begins at this date, and stocks make important changes in trend.

 

Dates at 45°, 90°, 135°, 180°, 225°, 270°, and 315° solar degrees from the Vernal Equinox (0° Aries) are what Gann called 'Natural Trading Days,' with 225° representing 0.618 of the solar year (November 7). Though 15°, 22.5° and 45° also may coincide with changes in trend, Gann stressed the importance of the cardinal points (90° apart). He also used multiples of 90° and 144°, i.e., 90°, 180°, 270°, etc., and 144°, 288°, 432°, 576°, 720°, etc. 

■ Divide the year by 2 to get 6 months, the opposition point or 180° angle, which equals 26 weeks.

■ Divide the year by 4 to get the 3 months’ period or 90 days or 90° each, which is 1/4 of a year or 13 weeks.
■ Divide the year by 3 to get the 4 months’ period, the 120° angle, which is 1/3 of a year or 17-1/3 weeks.

■ Divide the year by 8, which gives 1½ months, 45 days and equals the 45° angle. 

   This is also 6½ weeks, which shows why the 7th week is always so important.
■ Divide the year by 16, which gives 22½ days or approximately 3 weeks. 

   This accounts for market movements that only run 3 weeks up or down and then reverse. 

 

As a general rule, when any stock closes higher the 4th consecutive week, it will go higher. The 5th week is also very important for a change in trend, and for fast moves up or down. The 5th is the day, week, month, or year of Ascension and always marks fast moves up or down, according to the major cycle that is running out.
