[pt] A ESTRATÉGIA BETTING AGAINST BETA NO MERCADO DE AÇÕES BRASILEIRO / [en] BETTING AGAINT BETA STRATEGY IN BRAZILIAN STOCK MARKET

IGOR DE CASTRO LIMA 03 April 2020 (has links)
[pt] Este trabalho analisa a eficácia da estratégia do fator Betting Against Beta (BAB), estabelecido por Frazzini e Pedersen (2014), aplicado no mercado de ações brasileiro. Os resultados indicam alfa significativo e persistente para BAB no Brasil mesmo quando controlado para demais fatores de risco conhecidos. O desempenho do fator BAB foi analisado sob a especificação original e permaneceu robusto à variações do parâmetro de suavização e janelas de estimação dos betas ex-ante. Adicionalmente, verificou-se a relevância da inclinação da curva de juros spot do Brasil e condições de liquidez do mercado como previsores do desempenho de BAB. Os resultados indicam elevada significância da inclinação de juros e da liquidez do mercado na performance contemporânea do fator BAB. / [en] This paper analyzes the effectiveness of the Betting Against Beta (BAB) factor strategy, established by Frazzini and Pedersen (2014), applied to the Brazilian stock market. The results points to significant and persistent alpha for BAB in Brazil even when controlled for other well-known risk factors. BAB factor performance was analyzed under the original model specification and remained robust to changes of the beta smoothing parameter and different ex-ante betas estimation windows. Additionally, we analyze the relevance of the Brazil s yield curve slope and stock market liquidity conditions as predictors of BAB performance. The results points to high significance level of the yield curve slope and market liquidity as explanations for contemporary performance of the BAB factor.
