DEFINITION of 'Sports Illustrated Swimsuit Issue Indicator'

An indicator based on the nationality of the model on the cover of the Sports Illustrated swimsuit edition. The Sports Illustrated Swimsuit Issue Indicator attempts to provide insight into stock market returns for that year. The indicator suggests that when the cover model is from the U.S., the S&P 500 will generate a return above its historical rate, while a non-American cover model leads to underperformance by the S&P 500 for the year.
