Buyback
When sharp bettors bet the opposite side of a line after it has moved past the fair number due to public money. The line overshoots, and sharps buy it back the other way.
Like a stock that drops on panic selling and then rebounds when value investors buy the dip.
Why it matters
Buyback creates a window where the line is temporarily off from fair value. Recognizing this pattern helps you time your bets.
How DMP uses this
DMP's line movement tracking shows when lines reverse direction, which can indicate sharp buyback after initial public-driven movement.
Common mistake
Assuming all line moves are one-directional — lines frequently overshoot due to public money and then snap back when sharps step in.
