Super Bowl Indicator

An indicator based on the belief that a Super Bowl win for a team from the old AFL (AFC division) foretells a decline in the stock market for the coming year, and a win for a team from the old NFL (NFC division) means the stock market will be up for the year.

Though historically speaking the Super Bowl indicator boasts an 80% accuracy rate, remember the old maxim: correlation does not imply causation. In 2008, despite the New York Giants (NFC division) winning the Super Bowl (indicating a Bull Market), the stock market suffered one of the largest downturns since the Great Depression. Though the indicator is an interesting take on predicting the stock market, by no means should the correlation dictate an individual's portfolio construction.
