Resumo: | |||||||||||||
Considered the most widely used method for pricing and hedging options
by market participants worldwide, the Black-Scholes model (1973) assumes as
one of its premises to claim that the probability distribution price of a stock at any
future time, will always be considered log-normal. Assuming this premise does
not apply to the behavior of stocks traded on the Brazilian market, based on the
model s tendency to present lower prices for call options both inside and outside
money, constituting a phenomenon known as volatility smile, it was this analyze
in a comparative study for the period between September and October 2010, the
behavior of the returns of some of the most actively traded stocks on
BM&FBovespa, and estimate the daily prize of their options for models of Black-
Scholes (1973) and modified Corrado-Su (1996) which sets out to eliminate
phenomenon in question into consideration the variables of skewness and
kurtosis in asset returns analyzed. It was observed that both models
underestimated options out-of-money, while for options within-the-money, the
models had values mostly close to the market. It was found that the Black
Scholes model (1973) adjusted better choices out-of-money, at-the-money and
in-the-money, although the Modified model Corrado-Su (1966) has obtained a
significant representation among the events that had their prices closer to the
market. Finally, the results suggest that although the Black-Scholes model
(1973) fits slightly better for the Brazilian market, in general, we can’t say that one
model is superior to another in call options pricing.
