Effect of Wind on Stock Market Returns

Years later, when I had capital, I built that system. I found many correlations between words in the news and fluctuations in stock price. I developed algorithms to filter out future winners from over 8,000 stocks. Over the course of the two years I used this system, I looked at many stocks a day and even after two years, I had only examined about 1,600 stocks. The system I built tracked every time I viewed a stock and let me put notes in there, so I could remember why I looked at it the first time. It's almost impossible to rationally decide which among 8,000 companies to buy. Most of the great ones aren't even looked at. How many great winners of today hid among the 6,400 I never even saw? Most of the ones we see are the ones someone else wants us to see -- why?

When Katrina hit, I knew there'd be a lot of work on the coast and used the system to quickly find companies that would be employed to fix the mess. Over the next two years, these stocks beat the market substantially.

Point being, the weather, wind, words -- everything -- affects the stock market. Little of it is rational. Little of it is p/e, om, revenues... so I have little doubt that the wind has a big impact on share prices. Hurricanes certainly do.

"Lunar Cycle Effects in Stock Returns" http://papers.ssrn.com/sol3/papers.cfm?abstract_id=281665

Abstract: "We find strong lunar cycle effects in stock returns. Specifically, returns in the 15 days around new moon dates are about double the returns in the 15 days around full moon dates. This pattern of returns is pervasive; we find it for all major U.S. stock indexes over the last 100 years and for nearly all major stock indexes of 24 other countries over the last 30 years."
