When the sportsbooks post the opening point spreads, many times those numbers will change over the course of the day. The primary reason for line movement is money wagered on one side.
If the Bucks open at -4 against the Bulls and the majority of money is wagered on the Bucks, the point spread will likely move to Milwaukee -5, as the sportsbooks are trying to balance their books some by attracting bets on the Bulls. The point spread change makes the Bulls a bit more attractive and the Bucks slightly less attractive, which, in theory, should bring in a few more bets on Chicago.
In a reverse line move, the opposite happens of what should, in that the point spread in our example above would move to Milwaukee -3, even though the majority of bets are coming in on the Bucks.
In this case, the sportsbooks don't mind having the majority of bets on one side, and are actually trying to attract more wagers on that particular team. But while a sports bettors has to be correct 53-percent of the time to show a profit, sportsbooks only have to be correct 48-percent of the time to make money in the long run.
While the example we used above was for the point spread, reverse line moves also occur with the money line used in baseball and hockey betting. But instead of the point spread moving, the odds will change.
