We develop a novel method to decompose a straddle into a volatility risk portfolio and a jump risk portfolio. The …. We use the straddle decomposition to analyze the volatility risk premium and the jump risk premium embedded in a straddle … volatility risk portfolio persistently generates positive returns during earnings announcement periods …

We develop a comprehensive mathematical framework for polynomial jump-diffusions in a semimartingale context, which nest affine jump-diffusions and have broad applications in finance. We show that the polynomial property is preserved under polynomial transformations and Lévy time change. We...

In this note we provide an alternative proof that the Heston asset price process converges to the Normal Inverse Gaussian (NIG) distribution in the large-time limit in a certain sense. Our proof, which is based on the convergence of conditional time-integrated variance to the Inverse Gaussian...
