Investors can use this prediction interface to forecast CAC ALL historic prices and determine the direction of CAC ALL SHARES future trends based on various well-known forecasting models.

Additionally take a look at fundamental analysis of CAC ALL to check your projections.
A naive forecasting model for CAC ALL is a special case of the moving average forecasting where the number of periods used for smoothing is one. Therefore, the forecast of CAC ALL SHARES value for a given trading day is simply the observed value for the previous period. Due to the simplistic nature of the naive forecasting model, it can only be used to forecast up to one period.
This model is not at all useful as a medium-long range forecasting tool of CAC ALL SHARES. This model really is a simplistic model, and is included partly for completeness and partly because of its simplicity. It is unlikely that you'll want to use this model directly. Instead, consider using either the moving average model, or the more general weighted moving average model with a higher (i.e. greater than 1) number of periods, and possibly a different set of weights.
