Bipower volatility
WebPower and bipower variation with stochastic volatility and jumps Ole E. Barndorff-Nielsen TheCentreforMathematicalPhysicsandStochastics(MaPhySto), … 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 ...

Webcommonly used estimators of variation such as realized volatility, but it also encompasses more recently suggested quantities such as realized power varia-tion and realized … WebWe build a discrete-time non-linear model for volatility forecasting purposes. This model belongs to the class of threshold-autoregressive models, where changes in regimes are governed by past returns. The ability to capture changes in volatility regimes and using more accurate volatility measures allow outperforming other benchmark models, such …

WebThis is true whether the measure of future volatility is realized variance, bipower variation, negative re-alized semivariance or positive realized semivariance. Moreover, it is true for horizons ranging from one day to three months, both in-sample and (pseudo-)out-of-sample. Second, we use realized semivariances

In the framework of stochastic volatility models there is a wide range of applications of power, bipower and multipower variation, i.e. the sum of appropriately scaled absolute values of log-returns and neighbouring log-returns raised to a certain power.
