The S&P 500 has gained only 2.2% on average in years when the New England Patriots play in the Super Bowl. And with Tom Brady as the team's quarterback, the S&P 500 has fallen 3% on average when the Patriots play, notes a research report from LPL Financial Research.
What they're saying: "Pats fans might be ecstatic that Tom Brady is starting in a record-breaking ninth Super Bowl, but market bulls don't want to see the Pats win. Stocks are up only 1.5% for the year on average after a victory versus up 2.9% if they lose," said LPL senior market strategist Ryan Detrick. "Tom might be terrific, but maybe not in all markets."
