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 and swings ≥ 7 days are bisected (blue squares) to optimize short-term correlation. Previous examples [HERE].
