The models were compared using data on options traded on JSE Securities (Ltd). This paper looks at the differences in option pricing models and the apparent shortcomings of the Black-Scholes model. The JSE data was divided into Puts and Calls, and longer dated versus shorter dated derivatives. A chi-squared test was used in testing the results, and it was found that the Savickas option pricing model yielded results that were a better fit with the JSE data than the Black-Scholes. This is true for both longer and shorter dated options and to a lesser extent for the Puts. The conclusion is that the Savickas option pricing model and its assumptions that share price returns follow a Weibull distribution, is more accurate in pricing options than the Black Scholes model. The Black Scholes assumption that share price returns follow a log-normal distribution seems to be unrealisticenBlack-Scholes option pricing modelWeibull distribution option pricing modelThesis
