This paper presents a recombining trinomial tree for valuing real options with changing volatility. The trinomial tree … while having sensible transition probabilities between the nodes. The volatility changes are modeled with the changing … volatility, allowing also taking into account the level of the underlying asset price. The lattice can also be easily …

We propose different schemes for option hedging when asset returns are modeled using a general class of GARCH models. More specifically, we implement local risk minimization and a minimum variance hedge approximation based on an extended Girsanov principle that generalizes Duan's (1995) delta...

I propose an affine discrete-time model, called Vector Autoregressive Gamma with volatility Bursts (VARG-B) in which … volatility experiences, in addition to frequent and small changes, periods of sudden and extreme movements generated by a latent …

Volatility long memory is a stylized fact that has been documented for a long time. Existing literature have two ways … to model volatility long memory: component volatility models and fractionally integrated volatility models. This paper … GARCH(1, 1) model by generating 37% less option pricing errors. With stronger volatility persistence, it also dominates a …

To capture mean and variance asymmetries and time-varying volatility in financial time series, we generalize the … threshold stochastic volatility (THSV) model and incorporate a heavy-tailed error distribution. Unlike existing stochastic … volatility models, this model simultaneously accounts for uncertainty in the unobserved threshold value and in the time …

This paper studies the predictive ability of corridor implied volatility (CIV) measure. It is motivated by the fact … that CIV is measured with better precision and reliability than the model-free implied volatility due to the lack of liquid …-of-sample predictive ability of CIV is measured by the forecast accuracy of conditional volatility. It finds that the narrowest CIV measure …

Leveraged exchange-traded funds (LETF) are newly introduced ETFs that have become increasingly popular. It closely tracks the value of an underlying index while allowing for additional leverage. In this paper, we consider the valuation of options written on leveraged exchange-traded funds under...
