S&P 500 (SPX) performance by color-shaded Zodiac Signs (2016–2026),
New Moon, Full Moon and rosa-shaded Mercury Retrograde periods.
S&P 500 Strategy: Go long during bullish zodiac phases and short during bearish phases; hold through phase end with a 2% stop-loss (1% tighter stops improved results). Starting with $1,000, a 10 year walk-forward case study produced $5,410. The win rate exceeded RSI, Stochastic, and MFI, slightly outperforming Stochastic. Low-win-rate signs (e.g., Gemini at 39%) can be omitted.
Augmented version: Enter long only when Stochastic (14,1,3) ≤20 during a bullish phase; enter short only when ≥80 during a bearish phase; hold through the full phase. Python backtest: $18,571.79 over two years with a 66.67% win rate.
Using 10 years of S&P 500, Mercury retrograde periods frequently preceded major pivots, with post-retrograde directional flips.
