The Super Bowl Indicator is a spurious correlation that says that the stock market's performance in a given year can be predicted based on the outcome of the Super Bowl of that year. It was "discovered" by Leonard Koppett in 1978^[1] when he realized that it had never been wrong, until that point. This pseudo-macroeconomic concept states that if a team from the American Football Conference (AFC) wins, then it will be a bear market (or down market), but if a team from the National Football Conference (NFC) or a team that was in the NFL before the NFL/AFL merger wins, it will be a bull market (up market).

As of January 2022, the predictor had been right 41 out of 55 games, a 75% success rate.^[2] Without retrospective predictions, i.e. after its invention in 1978, it had been correct in 29 out of 43 games, a success rate of 67%.
