Study: Weather Influences Stock Movements

Good Day Sunshine: Stock Returns and the Weather, a paper from 2001, claims that there is a "strong and significant correlation" between sunshine at country’s leading stock exchange and market index stock returns (discussion ).


  1. Interesting study, although not enough to make me invest thousands of dollars the next bright sunny day we get.

  2. In a market like this that is influenced by mood swings as much as by the legit news, I wouldn't be surprised to see a correlation the paper describes.
