Webquantities, called realized power variation and bipower variation, respectively, are both quite robust to rare jumps in the log-price process. In particular, we demonstrate that it is possible, in theory, to untangle the impact of the presence of volatility and rare jumps by using power and bipower variation. Realized bipower WebWe develop a new option pricing model that captures the jump dynamics and allows for the different roles of positive and negative return variances. Based on the proposed model, we derive a closed-for...

It has been stated in Barndorﬀ-Nielsen and Shephard (2004); Ghysels et al. (2006) that the use of absolute return (and realized bipower variation) could capture the volatility better. 3.

WebApr 4, 2008 · With the aim of achieving this, we introduce the concept of threshold bipower variation, which is based on the joint use of bipower variation and threshold estimation. We show that its generalization (threshold multipower variation) admits a feasible central limit theorem in the presence of jumps and provides less biased estimates, with respect ... WebIts robustness property means that if we have a stochastic volatility plus infrequent jumps process, then the difference between realized variance and realized bipower variation estimates the quadratic variation of the jump component. This seems to be the first method that can separate quadratic variation into its continuous and jump components.
