Pittsburgh Steelers quarterback Ben Roethlisberger (7) beats New York Jets linebacker Josh Mauga (58) and defensive tackle Sione Pouha (91) on a 2-yard touchdown run against the New York Jets during the first half of the AFC Championship NFL football game in Pittsburgh Sunday.

BOSTON ( TheStreet) -- Stock investors looking for the biggest gains this year may find themselves rooting for the Pittsburgh Steelers to beat the Green Bay Packers in Super Bowl XLV.

The Steelers and Packers will meet in Super Bowl XLV after both teams were victorious Sunday in their respective conference championship games. Appearances in the championship game by both teams are historically good indicators of market returns, according to data collected by financial data and analytics firm Capital IQ.

The average return if the Steelers' represent the AFC in the big game is 25%, and when the Packers represent the NFC, the stock market has returned 24%, according to the data. Capital IQ calculated the annualized average returns for the S&P 500 from January 1967 through Dec. 31, 2010. The data are not intended to represent a fundamental analysis of market trends or historical data but instead are meant to take a light-hearted look at 44 years of Super Bowl history and stock market returns.

With a 6-1 record in the big game, the Steelers have more Super Bowl victories than any other team and will tie the Dallas Cowboys with an eighth overall Super Bowl appearance. The Packers, meanwhile, will be making their fifth trip to the Super Bowl and have a 3-1 overall record.

Bulls, however, should be rooting for quarterback Ben Roethlisberger and the Pittsburgh Steelers to defeat the Green Bay Packers and QB Aaron Rodgers. While having Pittsburgh in the big game is a good indicator for market returns either way, the average return after a Steelers' victory is a whopping 26%, according to Capital IQ's data. When the Steelers lost at Super Bowl XXX in 1996, the market return was 23% that year.

On the other hand, in the Super Bowl game the Green Bay Packers lost, the average market return was 29%. That compares with an average return of 23% after Packers' victories, according to the data.

While the Steelers and Packers have yet to square off against each other in the Super Bowl, the two storied franchises last played each other on Dec. 20, 2009, which resulted in a 37-36 victory for the Steelers at Heinz Field in Pittsburgh. The Steelers won the regular season game on a last-second 19-yard pass by quarterback Roethlisberger to wide receiver Mike Wallace.
