Sounds reasonable, right?
Well, maybe not.
Every year, a plethora of so-called indicators track what happens to the market in the event of a victory from a particular team, conference, jersey color, home team, away team, and on and on.
Those who would use the winning team in the Super Bowl to decide their investment strategy deserve what they get, of course. But it's still fun to look at the trends.
Paul Hickey at Bespoke Investment Group, which is a market leader in compiling trends that are actually useful for investors to follow, is at the front of the pack when coming up with some fun and fascinating trends connecting the Super Bowl and the stock market.

For instance, it wouldn't be all roses if Denver emerges the champion.
That's because the average return when an AFC team triumphs is just 4.3 percent, with positive results 63.6 percent of the time, compared with 10.4 percent and 80 percent when the NFC comes out on top.
Still, the Broncos look like the smart market play.
"Looking at the equity market's performance based on individual teams shows that bulls may want to buck conventional wisdom and root for the AFC this year," Hickey wrote in an analysis.

The Broncos also have lost the Super Bowl four times, and the market averaged a gain of just 2 percent in those years. Seattle has been to the big game just once, losing to the Steelers in 2006, a year when the S&P 500 gained a solid 12.2 percent.
"With the S&P 500 doing better when Denver wins than when Denver loses, and rising more than 10 percent in the one year where the Seahawks made it and lost, this year the bulls are rooting for the AFC," Hickey said.
The positive history of Denver victories is great news for Broncos fan David Twibell, president of Custom Portfolio Group in Englewood, Colo.
"Absolutely accurate—all the time," he joked when told of the Super Bowl indicators. "It's hard to go wrong with Peyton Manning as your quarterback."

In fact, as Twibell views it, the market will need all the luck it can get.
He foresees a tough year for investors after last year's massive gain, making for a market that can use a morale boost.
"This statistic may change my mind, but I think it's going to be a little rougher ride this year than last year, for a lot of reasons," Twibell said. "We may end up with a good year, but there's going to be an awful lot of roller-coaster rides between now and Dec. 31."
