With John Hampson
Market returns are higher into and around new moons, and lower into and around full moons. Lunar phase timings are known in advance. Market returns are higher in periods of negligible geomagnetism and lower on and after days of high geomagnetism. Geomagnetism can be forecast up to 3 weeks in advance (with limited accuracy). Stock market seasonality corresponds to historic geomagnetism seasonality.
Combining lunar phase oscillation with historic geomagnetism seasonality generates a model for the year. Combining lunar phase oscillation with cumulative trend geomagnetism generates a model with a 3 week tail into the future.
