Anomalies often occur with respect to asset pricing models, in particular the capital asset pricing model (CAPM). Although the CAPM was derived by using innovative assumptions and theories, it often does a poor job in predicting stock returns. The numerous market anomalies that were observed after the formation of the CAPM helped form the basis for those wishing to disprove the model.

Although the model may not hold up in empirical and practical tests, that is not to say that the model does not hold some utility.
