S&P 500 vs. Jupiter–Saturn Cycle: A Clock, Not a Crystal Ball

Derived mainly from M.A. Vukcevic's insights and solar-activity formula linking heliocentric Jupiter–Saturn sidereal orbits to model the sunspot cycle, the concept below uses a proprietary higher harmonics formula to project S&P 500 market swings.

S&P 500 vs. Jupiter–Saturn Cycle | H2 2026.

Over 90% of tradeable, high-amplitude waves develop in the 7 to 12-day window. 

  

Jupiter's sidereal period is ≈11.86 years, Saturn's ≈29.46 years, their synodic period ≈19.86 years, and the Jupiter–Saturn spring-tide period ≈9.93 years. These tidal frequencies bracket the ~11-year Schwabe sunspot cycle, while the Vukcevic and Scafetta formulas treat Jupiter–Saturn orbital geometry as a pacemaker of the solar dynamo. With no consistent polarity or directional bias for the S&P 500, the blue Jupiter–Saturn curve inflects within a 1-to-11.9-day window (median 7.0 days, mean 6.3), and swings ≥7 days are bisected (blue squares) to optimize short-term correlation.

The Jupiter–Saturn curve is not a crystal ball and it will not say whether to buy or sell. It is a clock. Two slow planetary rhythms were folded into a single wavy line, then sped up so that what once took years now takes days. That line rises, falls, and bottoms out again and again.

Troughs hold the edge — ignoring the rest saves energy. Troughs are the only feature showing positive 
statistical skill (+3 points over random chance). Peaks and midpoints offer zero edge over a coin flip.

After matching it to years of S&P 500 prices, only one part of the clock is worth attention: the low points, the troughs. The test is blunt. Each blue mark is given three calendar days to sit near a real 2% swing in the daily highs and lows; the same test is then run on random dates, so the extra percentage is the only thing that counts as skill. Troughs clear that bar. Peaks do not. Midpoints, whether a swing is cut in half by time or by height, do not either.

 Troughs mark volatility, not directional certainty. Blue troughs lean slightly toward S&P swing lows (+3 points),
but cannot guarantee direction. Attempting to trade blue crests yields negative skill vs. baseline expectation.

 

Target multi-day windows over intraday precision. Maximum predictive edge (+3.3 to +3.4 points) centers on 2%–3%
swings over a 2 to 3-day window. Expecting immediate same-day triggers introduces unnecessary market noise.

 

Those extra three points are modest, and they still do not pick a side. The color of the line — up or down — does not mean the market will follow. A trough lining up with an S&P low beats chance by about three points; a trough lining up with an S&P high does not. A peak is no better at calling a high than a low. In other words, a trough can sit under a rally or a selloff. It is a date when a real swing is a little more likely to finish, not a forecast of direction.

Used that way, the method is simple. The next trough is read from the calendar, including Saturdays and Sundays; the formula does not pause for the weekend. 

 

Filter out the daily ripples to trade the 7–12 day cycle. Short cycles under 6 days represent market interference
with negligible height. Over 90% of meaningful amplitude occurs within the 7–12 day wave structure.

A short window opens around that date: two days before through three days after, which is the same band in which most of those 63% of hits actually land. If the trough falls on a weekend, the window runs from the Thursday before through the Wednesday after. Inside that window nothing is done until the S&P itself speaks.

The wait is for price to carve a high and then drop at least two percent from that high, using the day’s actual high and low, not the close — that may be treated as a short, with risk defined just above the high. Or the wait is for price to carve a low and then rise at least two percent from that low — that may be treated as a long, with risk defined just under the low. Only the first such reversal is taken. If the window closes and neither has happened, there was no trade. The little wrinkles on the blue line are skipped as well: if the fall into a trough was tiny, it is interference, not a beat, and it can be ignored.

The position is left when it has paid twice what was risked, or when price completes a two-percent swing the other way, or when the next serious trough arrives. Then the wait begins again. A signal will not appear every week, and that is the point. A good year of this habit is a handful of attempts, not a lifestyle. Three extra points versus picking dates at random is not a license to force a trade; costs, hesitation, and the occasional late swing that lands a week off the mark can wipe the edge out.

What is being practiced is attention, not prediction. The market still has to print the turn in the window, in its own highs and lows, or there is no trade. Used that way, the curve earns a place on the desk: a reminder to look up for a few days, then to look away until the next low.

Derived from M.A. Vukcevic's solar-activity formula linking heliocentric Jupiter–Saturn sidereal orbits to model the sunspot cycle, the concept applied below utilizes a proprietary harmonic to project S&P 500 market swings.

With no consistent polarity or directional bias, the blue Jupiter–Saturn curve inflects within a 1-to-12-day window; thus, swings exceeding seven days are bisected (blue squares) to optimize short-term S&P 500 correlation. Previous examples [HERE].

"Mathematics is the Poetry of Logical Ideas" | M.A. Vukcevic

» Mathematics is the poetry of logical ideas, it is the silent language of reason. «

M.A. Vukcevic

 2003

 

Mathematics beautifully captures the essence of abstract thought, where logical structures unfold like verses in a poem, free from the noise of words or sensory distractions. Einstein's original phrasing highlights how pure math distills ideas into their most elegant, impersonal form, unburdened by empirical messiness. Math resonates and communicates truths across cultures and eras through symbols and proofs, relying on deduction rather than rhetoric.

OT - Impact & Explosion on Jupiter

http://georgeastro.weebly.com/jupiter.html

Apparently, something hit Jupiter during the early hours of Sept. 10th (11:35 UT), igniting a ferocious fireball in the giant planet's cloudtops. Amateur astronomer Dan Peterson Racine, Wisconsin, saw it first through his Meade 12" LX200 telescope. "It was a bright white flash that lasted only 1.5 - 2 seconds," he reports. Another amateur astronomer, George Hall of Dallas, Texas, was video-recording Jupiter at the time, and he confirmed the fireball with this video screenshot (left).

The fireball was probably caused by a small asteroid or comet hitting Jupiter. Similar impacts were observed in June and August 2010. An analysis of those earlier events suggests that Jupiter is frequently struck by 10 meter-class asteroids -one of the hazards of orbiting near the asteroid belt and having such a strong gravitational pull.

Astronomers around the world will now begin monitoring the impact site for signs of debris - either the cindery remains of the impactor or material dredged up from beneath Jupiter's cloud tops. Some impacts do produce such debris, while others don't. See also HERE & HERE 

Many think this is how and where planets and moons are created, and Immanuel Velikovsky's Worlds in Collision (1950) comes to light, proposing that around the 15th century BCE, Venus was ejected from Jupiter as a comet or comet-like object, passed near Earth (an actual collision is not mentioned).

The object changed Earth's orbit and axis, causing innumerable catastrophes which were mentioned in early mythologies and religions around the world. 

Fifty-two years later, it passed close by again, stopping the Earth's rotation for a while and causing more catastrophes. Then, in the 8th and 7th centuries BCE, Mars (itself displaced by Venus) made close approaches to the Earth; this incident caused a new round of disturbances and disasters. 

After that, the current "celestial order" was established. The courses of the planets stabilized over the centuries and Venus gradually became a "normal" planet. See also HERE

On September 9th the San Cristobal volcano in Nicaragua has rumbled to life with three explosions, forcing the evacuation of 3,000 residents. 

San Cristobal, located 135 km northwest of Managua, is one of the country’s most active volcanoes. Since Thursday, when an earthquake of 7.6-magnitude rocked neighboring Costa Rica and was also felt in Nicaragua.
People are now fearing the powerful quake would have an “impact on the activation” on several other active volcanoes in the region. See also HERE

Solar Activity vs Earthquakes and Volcanoes: When solar activity increases, the corpuscular emission and solar magnetic field strength increase rapidly as well, inducing ring currents in various layers of Earth, particularly, in lithosphere and astheposphere.  Currents in asthenosphere appeared as a result of solar activity increase cause mantle heating, its plasticity growth and as a result convection currents acceleration. Convection currents acceleration leads to spreading acceleration, and increase of mantle temperature – to its heat expansion while Earth extension is taken place due to spreading. In the periods of solar activity decrease the ring currents magnitude inducing in the mantle, decreases as well and as a result there decreases temperature and Earth compression, accompanying by the process of subduction.

Researchers have noticed coincidence between sunspot minima and occurrences of major earthquakes or volcanoes.The Earth’s iron core (source of the Earth’s magnetic field, i.e. the Earth’s dynamo) does not rotate around the same axes as the Earth itself, hence dislocation of magnetic poles. Jupiter-Saturn gravitational forces pull the Sun around its barycentre. The same forces pull the Earth’s mass centre away from its orbital trajectory, the eccentricity of the Earth’s iron core to the rest of its bodily mass causing drift of its magnetic poles. It follows that a certain major planets configuration will cause disturbances within the Earth’s interior which may initiate major earthquakes and volcanic eruptions. See also HERE & HERE
