SportsInsights put together some thoughts on its philosophy of “contrarian sports investing.” We publish betting articles and research on the topic — but why does it actually work? Is there really an edge? How robust are the results? A good betting strategy will have a fundamental reason for why it works — and will be backed up by results. Here, we take a “big picture” view of contrarian sports investing and “why it works.”

Prime Example: Indianapolis Colts vs. Tennessee Titans
This NFL match-up helped to motivate this article. This is a prime example of “contrarian investing” ( in any marketplace!) — “in action.” About 6 out of every 7 bets took Peyton Manning’s Indianapolis Colts, giving about three points. Indeed, earlier in the day, the betting percentages were even more “lopsided” — with a whopping 91% of bettors taking the Colts. The line opened at Colts -2 (at CRIS), but the steady pounding on the public favorite Colts pushed the line all the way up the Colts -3.5 (and even Colts -4 at some “public books”).
On the face of it, this game looked like a complete mis-match. How could last-place Tennessee compete with mighty Indianapolis? The Titans had lost five games in a row (entering Thursday night’s contest), and were getting just a field goal! Sports fans — and particularly sports bettors were drooling over this game, thinking:
Meanwhile, many SportsInsights’ members took “the road less travelled” and “bet against the Public.” SportsInsights made the Tennessee Titans an NFL Square Play selection.
And what happened? Indeed, the Colts jumped ahead 21-0 — and it was looking like a long night for the underdog Titans. However, the Titans came back and made it competitive. Very late in the game, the Titans were not threatening to win the game — BUT (and this is a big “but”) — their late touchdown gave them a “backdoor” cover “against the spread” (ATS). This allowed contrarian sports investors to squeak out a hard-fought value victory ATS.
How can “David beat Goliath?” Points Matter!
While Indy bettors are scratching their heads on how “that one got away” — “value sports investors” realize that this is a business of numbers and profit margins. The team at SportsInsights often writes articles and blog posts about “point spreads being a great equalizer.” Here are some thoughts:
Contrarian methods work in the sports marketplace, as measured by SportsInsights’ Square Plays. Below is a chart showing the results of “betting against the Public” using our Square Plays, which have been published for Members since 2003. The chart shows results for every major U.S. sport and is taken from our Sports Investing book.

Database & Research
In addition to the fundamental reasons behind contrarian approaches, SportsInsights’ results are based on years of research — and tens of thousands of games across the major U.S. sports. SportsInsights (SIs) has collected betting data for every major U.S. sport since the 2003. Data is available for seven major US sports — and may be purchased as a group — or for individual sports.
We collect the opening and closing lines (and “line movement,” for various sportsbooks) as well as final scores — and perhaps most importantly, SIs’ proprietary “betting percentages,” Our research team also “cleans” our data — to ensure our historical data is useful for our research articles and our Members. SIs’ historical database for each sport is an important part of our research and value-added for our Members. It is the backbone for our contrarian sports investing methods and you can’t find this kind of data and information anywhere else!
