No. of bitstreams: 1 Dissertacao final Daniel Lorenzo Mendes.pdf: 595820 bytes, checksum: ef1f86bcdf354637381b6f3bc2126b61 (MD5) Previous issue date: 2015-08-24 / In this work, we propose an econometric model specification in the short form, estimating by ordinary least squares (OLS) and based in macroeconomic variables, with the goal of explaining trimestral returns of stock index IBRX-100, between 2001 and 2015. Besides, we tested the forecasting efficiency of the model and concluded that the forecast error estimated in a moving sample, estimating OLS at each round, and utilizing auxiliary VAR to forecast variables, is lower than forecast error associated to the Random Walk hypothesis in the one trimester forward horizon. / Neste trabalho, propomos uma especificação de modelo econométrico na forma reduzida, estimado por mínimos quadrados ordinários (MQO) e baseado em variáveis macroeconômicas, com o objetivo de explicar os retornos trimestrais do índice de ações IBRX-100, entre 2001 e 2015. Testamos ainda a eficiência preditiva do modelo e concluímos que o erro de previsão estimado em janela móvel, com re-estimação de MQO a cada rodada, e utilização de VAR auxiliar para projeção dos regressores, é significativamente inferior ao erro de previsão associado à hipótese de Random Walk para o horizonte de previsão de um trimestre a frente.
