The impact of macroeconomic information releases on the smile shape: Evidence from the Australian options market
Abstract
Purpose
The purpose of this paper is to assign fair values to options reduces to the attempt to attribute correct implied volatilities. Here, the authors extend the study by Tanha et al. (2014) to determine the impact of macro economic announcements on the option smile.
Design/methodology/approach
First, the authors estimate the implied volatility function in terms of moneyness. The authors next analyse the impact of macroeconomic announcements on the estimated coefficients (b 0, b 1, b 2) by regressing the coefficients on the macroeconomic announcements.
Findings
The authors find that in-the-money options are sensitive to such announcements, but that out-of-the money options are not. This is consistent with the interpretation of investor behaviour from prospect theory.
Originality/value
The systematic pricing errors that have been documented using the Black-Scholes model have stimulated attempts to improve the model predictions. The approach uses DVF model to improve the B-S model.
