Asuming a portfolio of securities described by means of a multi-factor risk model, w discuss problems and choices posed by incoming new information. We present the risk model and define variables and parameters used. In the following sectioon, we describe a procedure for the evaluation of model adequacy. The choice of updating the model for the next period is developed. A similar framework is applied to the decision prpocess of updating the portfolio composition. The analysis is intended to give "advices" for organization and interpretation of available information, given the dominant role of the decision maker's preferences. In a technical appendix, different frequences of model updating are analyzed theoretically.
