>As soon as it predicted a future recession everyone would sell their long positions and the recession would happen almost instantly. The dilemma you propose relies upon a conflation of a prediction's accuracy with the prediction's adoption on a universal scale. You can see the flaw in that logic in this exchange here. Your prediction on how a market would behave given a perfect predictor, if accurate, has not garnered my belief, so the universality of it's adoption has failed regardless of its validity.
