SPX vs Solar Activity

Last 30 Days Daily Solar Data

Solar flares and CMEs are intense flashes of extreme radiation emanating from the Sun.  

The ejected material is a plasma consisting primarily of electrons and protons, but may contain small quantities of heavier elements such as helium, oxygen, and even iron. 

Most solar flares and coronal mass ejections originate in magnetically active regions around visible sunspot groupings. 

Near solar maxima the Sun produces about three CMEs every day, whereas near solar minima there is about one CME every five days (see also HERE).

3-day Solar-Geophysical Forecast

Solar flares are classified according to the peak flux as Class A, -B, -C, -M or -X Flares (ranged from small to large). Daily Solar Data, a 3-day Report of Solar and Geophysical Activity, as well as a 45 Day F10.7cm Flux Forecast are provided free of charge by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center.

For the purpose of market timing only Class M and -X flares are relevant. However, not every flare ejected by the Sun is directed towards the Earth. But if it is, the solar storm takes 2 days +/- to trigger a geomagnetic storm. In 2003, the Federal Reserve Bank of Atlanta did a study on the effects of solar storms on stock market traders: "Unusually high levels of geomagnetic activity have a negative, statistically and economically significant effect on the following week’s stock returns for all US stock market indices."

Therefore, some 2 days +/- after an earth-directed Class M or Class X flare a drop in the stock markets should be expected.

So what about the latest Class M flares on September 8th and 9th? They will miss to hit the Earth (see also HERE). Instead various 10.7cm Flux Forecasts suggest the stock markets will keep wedging up into around the New Moon (Sep 15) or even the Equinox (Sep 22). Please note: Solar-, lunar- and other astro-indicators frequently fail around Equinoxes (inversion periods are: March 21 - April 7, , June 7 - July 7, September 9 - October 11, December 8 - January 6).
