Cutting Edge: Pure jump models for energy prices

Université de Lausanne’s Roberto Marfè investigates pure jump processes as modelling blocks for the distributions of energy returns under the pricing measure. An easy-to-implement option-implied approach is outlined, which circumvents most of the…

Parameter estimation with k-means clustering

Ever since the pioneering work of Cox, Ross & Rubinstein (1979), tree models have been popular as an asset pricing method. However, statistical estimation of the parameters of tree models has been less studied. In this article, Kiseop Lee and Mingxin Xu…

Vix option pricing in a jump-diffusion model

Artur Sepp discusses Vix futures and options and shows that their market prices exhibit positive volatility skew. To better model the market behaviour of the S&P 500 index and its associated volatility skew, he introduces the stochastic dynamics of the…
