The Super Bowl Indicator: Wall Street’s Unique Market Predictor

Many on Wall Street are eagerly awaiting the outcome of this Sunday’s Super Bowl, not for the love of the game, but because they believe in the infamous “Super Bowl Indicator”. This theory states that the U.S. stock market will rise for the year if the winning team was never a part of the original American Football League (AFL) or was in the NFL prior to the AFL-NFL merger in 1966. This year, if the San Francisco 49ers win, the market is expected to soar; however, a victory for the Kansas City Chiefs may cause a severe drop.

The Dubious Track Record of the Super Bowl Indicator

Although the Super Bowl Indicator has gained a lot of attention, its reliability is questionable at best. In fact, the person who came up with the theory, sportswriter Leonard Koppett, created it as a joke and was surprised when it gained so much traction on Wall Street. The Super Bowl Indicator’s success rate is worse than a coin flip, making it a rather fickle predictor of the market’s performance.

The Origins and History of the Super Bowl Indicator

Koppett first mentioned the Super Bowl Indicator in the Sporting News sports magazine in February 1978. It gained popularity on Wall Street thanks to William LeFevre, editor of the investment newsletter “Monday Morning Market Memo,” and Robert Stovall, then president of Stovall Twenty First Advisors. However, Koppett expressed his hope that the Super Bowl Indicator would eventually be declared “dead as a doornail” before his death in 2003.

The Importance of Out-of-Sample Testing

The Super Bowl Indicator serves as a reminder of the importance of subjecting all stock market patterns to out-of-sample testing. It is crucial to measure a predictor’s success rate after its discovery to avoid falling for spurious correlations that may appear accurate only in historical data. This lesson extends not only to believers in the Super Bowl Indicator but to financial academics as well.

The Replication Crisis in Academic Finance

Campbell Harvey, a finance professor at Duke University, has identified a “replication crisis” in academic finance. After studying the out-of-sample performance of 400 strategies that were claimed to outperform the market according to previous academic research, Harvey found that at least half of them were invalid. This highlights the need for rigorous testing and skepticism when it comes to financial strategies and predictions.

Bottom Line: Enjoy the Game, Don’t Worry About the Market

In conclusion, while the Super Bowl Indicator may attract attention, it is far from a reliable predictor of stock market performance. Investors are urged to enjoy the Super Bowl without concern for its implications on the market. Serious investors should focus on thorough research, data analysis, and validated strategies to make informed decisions rather than relying on whimsical indicators like the Super Bowl outcome.
