WebDec 1, 2014 · This paper inherits the intuition of the bipower variation estimation and extends the method to the correlated return process by modeling the price process using the fractal Brownian motion process. The fractal Brownian motion model has been used to model the long-memory in return series, thus the serial correlation in returns. WebRealised bipower variation consistently estimates the quadratic variation of the contin-uous component of prices. In this paper we generalise this concept to realised bipower …

WebJan 1, 2004 · This article shows that realized power variation and its extension, realized bipower variation, which we introduce here, are somewhat robust to rare jumps. We … WebIn this paper we provide an asymptotic analysis of generalized bipower measures of the variation of price processes in financial economics. These measures encom-pass the …
WebVolatility Decomposition. Asset prices are usually modeled as a continuous diffusion process with random jumps. By decomposing an asset's price variance into continuous and jump components, better risk management and asset allocation for a portfolio can be achieved. In order to compute price variations, returns are first calculated and ... 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 …
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 ...

WebThis paper provides limit distribution results for power variation, that is, sums of powers of absolute increments under nonequidistant subdivisions of time and for certain types of time-changed Brownian motion and α -stable processes. Special cases of these processes are stochastic volatility models used extensively in financial econometrics. greencastle aldiWebBarndorff-Nielsen, Ole Eiler & Graversen, Svend Erik & Jacod, Jean & Podolskij, Mark, 2004.
