What do Line Movements mean?
When you are trying to win money in sports betting, line movements are something that you should be paying special attention to. Now you should be aware that a 'line' is simply the odds on the bet that the bookie is offering. Any bet with odds is said to be the line.
What Line Movement Really Means
So what does line movement mean? The meaning is very simply the alteration in betting odds for whatever reason. Odds are not set in stone but are in fact fluid things that bookies will often change as more information on the game comes in. So the line movement is the change in odds from one offering to another.
Of course knowing the meaning of the phrase 'line movement' is of little value by itself. Far more important to anyone betting is understanding why they move, what causes such trends and seeing if they can use such information to their own betting advantages.
So let us take a look at what causes line movement.
The bookies have inside information
This is the big one. Almost all bookies will have someone on the inside of top teams feeding them information. It can be on a huge number of variables, all of which will effect the line movement. For example it could be:
- They know the starting line up before it is published
- They know if a player is injured, or returning from injury ahead of schedule
- Any inside troubles such as fighting amongst teammates
And much, much more. The bookies almost always have more inside information than any bettor has access to. This means that they are able to cause line movement ahead of any information going public, so that they are not going to get caught behind the public.
For instance if they know that a star quarterback were injured for a big
NFL football game, but it was not yet public news, they would move their line to lengthen the odds for that team. They would do this ahead of any public announcement to stop those who have heard rumors from taking advantage of the oppositions better odds prior to the move.
A Number of Bets
Another factor to effect the line movement is the amount being bet – both in number and in size of bets. If there is a large amount of betting going on one side of the line one of two things will happen. The bookies will believe that they have missed some information and lengthen the odds. Or, the bookies will mitigate the risk of so many bets by lessening the odds.
So how popular a bet is has a direct relationship with the line movement of a bet. In live betting of course there is far more movement of the line – simply because there is so much going on at any one time that can have a direct impact on the outcome of a game.
What Does This Mean to You?
There are a number of tactics that involve following line movements in betting. It could be that you will follow the line, betting on the side that is decreasing in odds believing that you can still get the jump. You believe the odds are moving for a reason and that the line will continue to shorten.
This is as valid as any other betting system because often it will be that the shortening of the odds means that any value from the bet has gone, especially if you had already placed a bet on that game with different odds. You should carefully consider such movements.
Another tactic is to follow the line movement and as soon as you see a movement in one bookie you hunt out another that hasn't started to move. This is potentially very profitable but it does rely on line movements to be happening for a reason, not because bettors have decided to favor one team over another (which happens a lot, often for very little reason).
As always, with betting it is best that you understand what you feel the best odds are and ensure that you hit them. Settling for odds you think are a risk almost always are a risk, no matter what the movement. Knowing how line movements work is just one of the many weapons needed to become a great sports bettor.
