NFL line movement basics
An educational, non-proprietary guide with original worked examples and clear limits on what market information can establish.
Direct answer: A point spread is a market price expressed as a margin. The favorite gives points, the underdog receives points, and the attached American price shows the cost of that position.
A simple worked example
BUF +3.5 · -105
Buffalo receives 3.5 points for grading purposes. A -105 price means the market cost differs from the familiar -110 baseline. The half-point prevents a tie on a three-point final margin.
Price and spread belong together
Comparing only the spread can hide the cost attached to it. A larger underdog spread may look preferable, but the associated price can materially change the tradeoff. SharpFish keeps both values structured rather than collapsing them into a label.
What movement does not prove
Movement alone does not guarantee an outcome, a profit, or a qualifying SharpFish Market Alert. It is one observable market condition. SharpFish applies separate governed standards before any official Market Alert is issued.
