Abstract | ABSTRACT In 2015, the Financial Economics Research Center (NEFIN) of the University of São Paulo proposed an implicit volatility index for the Brazilian stock market based on the daily prices of options for the Bovespa index (Ibovespa) and that measures the expected volatility of the Ibovespa in the next two months. The aim of this study is to determine whether this implicit volatility index can be considered an antecedent indicator of future returns of the Brazilian stock market, given that it represents the expected volatility of the Ibovespa two months into the future. This study contributes to the literature on the implicit volatility index for the Brazilian stock market, which has been scarce until now. This happens due to the recent establishment of the index and due to the fact that there is not an official one published by the B3 S.A. - Brasil, Bolsa, Balcão (B3). Given the relationship found between the Brazilian implicit volatility index and the future returns of the Ibovespa, investors could anticipate instabilities in the Brazilian market by putting together strategies to protect their investment portfolios, as well as identifying opportunities to enter and exit the market. This research corroborates in disclosing the Brazilian implicit volatility index in order for it to become more widely used in academia and in the Brazilian financial market. The increase in studies on this index may also incentivize the launch of an official implicit volatility index by the B3. The relationship between the Brazilian implicit volatility index and the future returns of the Ibovespa is examined using least squares and quantile regressions. The implicit volatility index for the Brazilian stock market could help in predicting the future returns of the Ibovespa, especially for 20-, 60-, 120-, and 250-day future returns.
RESUMO Em 2015, o Núcleo de Pesquisa em Economia Financeira (NEFIN) da Universidade de São Paulo propôs um índice de volatilidade implícita para o mercado acionário brasileiro baseado nos preços diários das opções do índice Bovespa (Ibovespa) e que mede a volatilidade esperada do Ibovespa nos próximos dois meses. O objetivo do estudo é averiguar se esse índice de volatilidade implícita pode ser considerado um indicador antecedente dos retornos futuros do mercado acionário brasileiro, dado que ele representa a volatilidade esperada do Ibovespa dois meses à frente. Este estudo contribui para a literatura sobre o índice de volatilidade implícita do mercado acionário brasileiro, que, até esse momento, é escassa devido a esse índice ter sido estabelecido recentemente e não haver o oficial publicado pela B3 S.A. - Brasil, Bolsa, Balcão (B3). Comprovada a relação entre o índice de volatilidade implícita brasileiro e os retornos futuros do Ibovespa, os investidores poderão antecipar instabilidades do mercado brasileiro, estruturando estratégias para proteger suas carteiras de investimentos, bem como identificar oportunidades de entrada e saída do mercado. Esta pesquisa colabora para a divulgação do índice de volatilidade implícita brasileiro a fim de que se torne mais difundido na academia e no mercado financeiro brasileiro. O aumento de estudos sobre esse índice pode também incentivar o lançamento de um índice de volatilidade implícita oficial pela B3. A relação entre o índice de volatilidade implícita brasileiro e os retornos futuros do Ibovespa é examinada utilizando regressão por mínimos quadrados e quantílica. O índice de volatilidade implícita do mercado acionário brasileiro pode auxiliar na previsão dos retornos futuros do Ibovespa, principalmente para retornos futuros de 20, 60, 120 e 250 dias. |
