Prediction Accuracy

* A score of 55 or more counts as an "up" call and 45 or less as a "down" call; 46-54 is neutral and not scored.
* The starting price is the close on the day the score was recorded; the outcome is the close 1, 5 or 21 trading days later.
* A call is correct when the price moved in the called direction. Calls whose horizon hasn't passed yet are "pending".
* The baseline is how often prices simply rose over the same horizons, so accuracy can be judged against "always say up".
* Forecast error is the Brier score of VEXA's up-probability (0 is perfect, 0.25 is what a constant 50% guess scores).
Results only cover days since recording began, with the stocks in VEXA's price data. Small samples mean little.
