When sportsbooks initially release their betting lines, they rely on a mix of secret and sophisticated qualitative and quantitative methods to set both the lines and their associated odds. Yet, what prompts these odds to shift after their release?
Understanding the dynamics behind line movement can be complex.
To shed light on this, we consulted Anthony Best, a seasoned professional handicapper, to gain deeper insights into the methods bookmakers use to set their odds and strategies to outsmart them. Surprisingly, the true drivers behind these changes are not always what one might expect.
Mastering the Basics: How Bookmakers Set and Adjust Lines
Understanding the bookmakers’ objectives in setting lines is crucial before delving deeper. Bookmakers aim for balance, trying to attract equal bets on both sides to minimize risk and secure their profit from the vigorish (vig), typically around 5-10%.
Setting the Perfect Line
In an ideal scenario, bookmakers seek to balance betting on both sides to simply collect the vig without taking any risks. However, achieving this balance is rare, leading bookmakers to employ tactics to encourage equal wagering.
Why Lines Move: The Principles of Supply and Demand
Bookmakers adjust lines based on supply (betting volume) and demand. If one side of a bet is lacking action, they will modify the odds to make it more appealing, thus balancing the betting.
For example, to increase bets on a favorite, they might change the spread from -7.5 to -6.5. Conversely, if there’s too much action, they might shift the spread to make the bet less appealing.
