Super Bowl Indicator is a legendary stock-market forecasting device predicting stock prices over the coming year based on the Super Bowl. If the winning team can trace its roots back to the original National Football League (NFC division), prices of stocks will rise, and they will fall if that team's roots are in the old American Football League (AFC division).
Additional meaning of Super Bowl Indicator:
Followers claim that the indicator has been surprisingly accurate with its 79% success rate over the past years, far better than most other stock market timing systems. The indicator is subject to interpretive issues since fewer and fewer teams are actually from the original American and National Football Leagues.
