Price Performance vs. Zodiac Signs, Lunar Phase & Mercury Retrograde

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.

SPX vs George Bayer's Rule #4A - Mercury 80 Years Ago

MERCURY 80 YEARS AGO

We use the geocentric ephemeris, concentrate only on Mercury as it passes through the Zodiac. We mark each day when this planet enters a new sign 80 years ago, i.e. when it arrives at 0 degrees. We also mark those days in which Mercury turns retrograde or direct. Note, that a planet changing signs and going direct, respectively retrograde are two entirely different things, but for our work they fit together. Here is a list of these places together with the dates when they happened back in 1857. These dates are to be carried over to the year 1937, exactly 80 years further according to the Sun’s motion and not according to Mercury’s motion. All quotations are for Mercury only. In this example the years 1857 and 1858 were used.

1857 – equals 1937         1858 – equals 1938
3/31  0 Aries                 1/6 retrograde
5/20 retrograde            1/26 direct
6/17 direct                   2/13  0 Aquarius
7/23  0 Leo                   3/6-7  0 Pisces
10/10 direct                 3/23  0 Aries
11/22  0 Sagittarius      4/6  0 Taurus

Each and every one of these positions gave 80 years later  tops and bottoms not of a few points but of from 50 to 200 points in hides. Look up the dates on the hide charts. Note: The very same calendar days are used 80 years later.

SPX vs Outer Planets Going Retrograde / Direct

(Calculated and charted with Sergey Tarassov's Timing Solution).

Stock markets' trend usually changes when the planets change direction, especially the outer ones.

11.10.2012  22:50 SA = Neptune direct 

T.S. Phillips: "This week’s major planetary event is Tuesday’s total Solar Eclipse  ... as Mercury squares Neptune ... The key reversal day of the week is likely to be after hours on Tuesday or on Wednesday." 

SPX vs George Bayer's Rule #22 - Mercury is Retrograde and Conjunct the Sun

MERCURY RETROGRADE PASSES OVER THE SUN

This case occurs frequently. The effect is a change in trend. The planet must be retrograde and not direct in order to give the effect. An example is March 15, 1940. Hundreds of others can be located by you through any years. This rule works practically all the time. These conjunctions occur four times a year.
