Nevin's Data "Points"

   The Patriots and Seahawks have some Super Bowl history — and some think the outcome might have an impact on the stock market — not to mention your 401(k)!  Yes, that’s what adherents of the so-called Super Bowl Indicator [i]  would have you believe — based on a “theory” that when a team from the old National Football League wins the Super Bowl, the S&P 500 will rise, and when a team from the old American Football League prevails, stock prices will fall.
