For more info on how the sunspot cycle affects the economy, geopolitics, and the stock market, watch this CNBC interview with cycles analyst and market technician Charles Nenner from 2010. Simply put, the sun has a psychological effect on people's moods which can affect the global economy, geopolitical tension, and the buying and selling of shares. This makes sense given that the amount of sunlight affects the levels of serotonin in people's brains, which can cause depression (Discovery, WebMD, PubMed). When looking at trading and investing specifically, some people believe the sunspot cycle directly affects complacency in the stock market. So maybe the Fed should soak dollar bills in synthetic anti-depressants or St. John's Wort extract (interesting that a side effect is photosensitivity (Fordham, PubMed)) to "QE" the next downturn in the sunspot cycle.
Here is the S&P 500 vs. Sunspots chart I made today showing the new divergence.
