Reverse Line Movement
When the betting line moves in the opposite direction from where the majority of bets are placed.
Reverse line movement occurs when the line moves against the public betting percentages. For example, if 75% of bets are on Team A, but the line moves to make Team A more attractive — that suggests sharp money is on the other side.
Sportsbooks weigh dollars more than ticket count. A few sharp bettors placing large wagers on the unpopular side can move the line more than thousands of small recreational bets on the popular side.
Reverse line movement is one of the most widely tracked indicators of smart money. While it's not a guaranteed signal, it's a useful data point when combined with other analysis.
