Generally when talking about price movements the opposite is true. That is a prediction that the market will move at some point in the future will cause that move to happen right now instead, but only if that prediction is believed. And if you have a model that people believe which predicts the movement of stocks but doesn't have any good reason for those predictions then it may very well move the price of those stocks in the ways that it predicts. But in doing so the money of the people who believe its predictions will be transferred to the people who don't until it stops having an effect.
