Pigskin predictions bring us this week's Marketplace Money buzzword--Superbowl indicator.

The superbowl indicator is a common Wall Street superstition. Supposedly, if one of the 16 original NFL teams wins the big game, the stock market goes up. If the winning team is a relative newcomer to the league, then stocks go down. Most experts find the theory silly, but boosters say it's 80% accurate. And consider this, both of this year's teams, the Indianapolis and the Bears were in the original NFL. So no matter who wins, it could mean victory for the market. Go stocks, woo hoo.
