Neste estudo procurámos testar a possibilidade de prever, de forma lucrativa, a evolução futura do índice accionista BVL Geral, a partir dum conjunto de regras de transacção semelhantes àquelas que vulgarmente são utilizadas pelos analistas técnicos. As regras foram estimadas utilizando um método denominado programação genética. O nosso objectivo ao aplicar este método foi evitar incorrer no problema de data snooping de que enfermam diversos estudos anteriores acerca deste tema. Os resultados obtidos confirmam a hipótese segundo a qual as regras testadas permitem aos investidores prever a evolução do índice accionista BVL Geral.

The rules were estimated using a method named genetic programming. Our purpose in applying this method was to avoid data snooping, a problem existent in several previous studies focusing this theme. The results we obtained confirm the hypothesis that the rules tested enable investors to forecast BVL Geral stock index’s evolution.
