Analysis of the implementation of a stock investment strategy based on a decision aid tool
The present study analyzes the interface between two disciplinary fields - finance and operational research. In this sense, it integrates two approaches to investment analysis - fundamental and technical, as well as an investor’s concern at the time of resources allocation in a Buy & Hold investment strategy. The study uses the Multicriteria Decision Aid (MCDA) as an instrument of intervention. As for results, it was evident that the instrument of intervention used, together with a pre-defined investment strategy, was able to support the decision maker at the time of allocation of resources, generating an accumulated return of 25.14 % in the period, compared with a negative return -13.41% of the Bovespa index in the same period. In order to check the robustness of results, regressions were performed with both the CAPM model as daily and weekly data, and the t test performed on the coefficients of the regression was significant at 1% for the abnormal return of weekly data and 0.1% for the return of abnormal daily data; in addition, the t-statistic was positive in both cases, indicating the presence of abnormal positive feedback, i.e., the portfolio proposed here outperformed its benchmark.
