In a previous article, SportsInsights.com summarized some of the academic research performed on baseball and hockey – as well as horse racing. In this article, we summarize research on football – both professional and college football.
The information below is gathered from various sources and journals that are not affiliated with SportsInsights.com. However, these academic sources lead to the same conclusions as SportsInsights.com’s independent research: that there is a bias towards betting on underdogs and unders; and that “Betting Against the Public” can lead to value. The information on this site is for entertainment and educational purposes only. Use of this information in violation of any federal, state, or local laws is prohibited.
Various authors have tackled the issue of whether or not the sports marketplace is efficient. The general conclusion is that certain biases exist. Some professors claim that profits can be earned in the markets while others claim that although biases exist – they are barely enough to make up for the vig.
Borghesi (2003) is one author who believes that significant mis-pricings occur in the NFL sports betting market. He states, “Market inefficiencies persist because participants discount old information and are slow to process new information.” Gouldey (2005) says, “Statistically significant evidence is found that the market is not weak-form efficient and that speculative profits (after transaction costs) can be earned using the information set based only on quoted betting and realized point spreads.” On the other hand, another set of authors (Sauer, Brajer, Ferris, and Marr, 1988) “present a variety of evidence that contradicts (the) assertion that the betting market for NFL games is inefficient.”
There’s a famous saying, “The only constant is change.” This can be said about the sports marketplace and financial markets in general. If excess returns can be earned in the marketplace, market participants will enter the marketplace and eventually drive the bias away.
At SportsInsights.com, we strive to give you the real, honest scoop. Sports betting is not easy. Most people lose money. However, if you take a serious, professional view of sports investing, you should be able to profit from the sports marketplace. We hope that you will use the tools that SportsInsights.com has put together – and that they will help you to a profitable and exciting football season.
We do not guarantee that the trends and biases academic researchers and SportsInsights.com have found will continue to exist. It is impossible to predict the future. Any serious academic research in the field of “market efficiencies” recognizes that inefficiencies may disappear over time. Once inefficiencies are discovered, it is only a matter of time before the market corrects itself. We do not guarantee our data is error-free. However, we at SportsInsights.com have tried our best to make sure every score and percentage is correct.
