What it indicates
If 75% of tickets are on one team and the line moves towards the other, something other than ticket volume is driving it. Usually that means a smaller number of much larger bets on the unpopular side, which is why reverse line movement is treated as a sharp-money signal.
How much to trust it
It is a real signal but a noisy one. Books also move numbers to manage their own exposure, and public ticket percentages are widely available and therefore already priced in. Reverse movement is worth noticing, not worth blindly following.

Is reverse line movement a reliable signal?+
It is a genuine signal but not a strong one on its own. Books also move lines for their own exposure reasons, and the underlying data is public enough to already be reflected in prices.
