| Summary: | The CAPM model has attracted great interest from the scientific community over the last decades. Despite criticism, improvement of the static CAPM has given origin to new dynamic models providing investors with more safety along the business cycles. The CAPM and the static versions continue to be of great importance in Finance and now more complex adaptations provide answers to some questions in finance for which solutions were not yet available. Therefore considering this situation and the discussion of CAPM validity, advantages of the conditional model were presented in relation to the static model. Tests of conditional models were studied where beta varies with time, COM E SEM CAPITAL HUMANO, which is not commonly studied in literature. These tests incorporate variances and covariances that change with time. |
