You can't knock traditional analysis. And the above chart from the folks at livecharts.co.uk does a great job. But one fundamental weakness in it, is that it uses markets own values to predict values.
Aspects in Astrology, have absolutely nothing to do with the markets per se. They are the angles that exist between the various planets, moon, and other stellar entities.
The fact that there is a correlation, and that it goes way into the future is the very essence of this form of analysis.
