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.

Capital IQ also ran the data against various aspects of the Super Bowl, including high-scoring vs. low-scoring games, AFC versus NFC, city, home vs. away games, and dome or no dome. Several pieces of the data were also positive for bullish investors. For one, if a previous Super Bowl champ wins again, the average market return is 13%. Both the Packers and Steelers have won several NFL title games. Other trends observed in the data tend to favor the Packers. The market averages a 15% return after an NFC win vs. a 7% return after an AFC win. Capital IQ does note that the best market return (38% in 1995 after the San Francisco 49ers beat the San Diego Chargers) and the worst return (-37% in 2008 when the New York Giants defeated the New England Patriots). The Packers are considered the home team in Super Bowl XLV, and the market return averages 17% when the home team wins. Already, Green Bay is favored by 2.5 points by Vegas bookmakers. Bears -- not the ones from Chicago -- will be happy to know that the investor outlook isn't good for championship games played in Texas. The average returns in the years after games were played in Texas is -8%, ranking as the worst average of any of the seven states that have hosted the Super Bowl, according to Capital IQ's data. And for all the attention that the new Cowboys Stadium will receive during Super Bowl week, the domed stadium also bodes poorly for the stock market. Jerry Jones' crown jewel does have a retractable roof to go along with the massive high definition video screen, but the data show that Super Bowl games played in domed stadiums precede a market return of only 3%, compared to a 15% return after games played outdoors. While it may be hard to predict the score of Super Bowl XLV, the market tends to favor higher-scoring games, according to the data. For Super Bowl games resulting in a final total combined score of at least 45 points, the stock market return 17% on average. If the final combined score is under 45, the average market return is 5%.The total points line for the game opened at 46 points, according to Linesmaker.com. Fans of the New York Jets do have a small nugget of good news after the playoff-ending loss to the Steelers late Sunday. The stock market fell by 8% in the lone appearance by Gang Green in Super Bowl III, so a victory in Super Bowl XLV would not have been a good omen for market returns in 2011. -- Written by Robert Holmes in Boston. >To contact the writer of this article, click here: Robert Holmes. >To follow Robert Holmes on Twitter, go to http://twitter.com/RobTheStreet. >To submit a news tip, send an email to: email@example.com.
