In this article, we have tested the volatility of the returns of the 3 – month AstraZeneca call option contract for changing conditional variances. Threshold generalized autoregressive conditional heteroskedastic models, (TGARCH), exponential generalized autoregressive conditional...

We analyze the implied volatility smile of a lognormal distribution on a on a 6 – month EUR/USD call currency option contract using the ratio of strike and share price. There is significant time variation in the implied volatility smile and the traditional Black – Scholes model can not...

We analyze the implied volatility smile of a lognormal distribution on a on a 6 – month EUR/USD call currency option contract using a random standard normal variable. There is significant time variation in the implied volatility smile and the traditional Black – Scholes model can not explain...

We analyze the implied volatility smile of a lognormal distribution on a 3 – month Danske bank call option contract using the option delta. There is significant time variation in the implied volatility smile and the traditional Black – Scholes model can not explain this deviation. The Black...

Autoregressive Conditional Heteroskedastic models (ARCH), and Generalized Autoregressive Conditional Heteroskedastic models, (GARCH) take into account the non-linearity that arises in the financial time series. Well known anomalies such as the calendar effects, January effect and seasonality's...

In this article, we focus on one-period and two-period binomial methods to calculate the payoff of the expected value of the 6 month call option of Nordea Bank based on probabilities of share changes. Then, we discount the expected value of the call option back to today base on the risk-free...
