so the original contention was ~ how can celestial bodies have any effect on us? .....
First off, we are talking about HUGE forces that predate mankind. My question is - how could there not be an effect? What forces? Well, GRAVITY. for one. And RADIATION, for another. talking photons and alpha beta particles et al.
Why would Gravity have an effect? - Human body is about 70% or so water. Water and land are both pulled up by the tidal force of the moon here on earth, so we are literally pulled by our nearest heavenly body.. Fine, are there any market correlations?? research it yourself to find out.
Regarding solar radiation's effects on financial time series, see for yourself one bit of research =

as i've learned it, the output of the Sun is not constant! it varies +/- 2%, based on the positions of the planets and the deformation of the Sun by their gravity. the energy output of the Sun is enormous, more energy pours onto the Earth from the Sun each day than has been used by humans in all of human history.
so, we are probably affected by these things, but we are largely ignorant of the fact. financial markets give a great place to conduct research on this.
also, arch crawford has a reading list, worth checking out.
