WebMay 23, 2006 · In this paper we provide an asymptotic analysis of generalized bipower measures of the variation of price processes in financial economics. These measures encompass the usual quadratic variation, power variation, and bipower variations that have been highlighted in recent years in financial econometrics. The analysis is carried out … WebGiven the increasing popularity of the bipower volatility estimator, an important topic for future research is the development of formal rules for choosing the critical or optimal sampling frequency. In addition, it would appear to be useful to develop kernel-based or subsampling-based extensions to volatility estimators that are based on 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 ...

REALIZED VOLATILITY WHEN SAMPLING TIMES ARE POSSIBLY …
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 Webvolatility: realized volatility, bipower variation, and both real-ized semivariances. Third, we show the usefulness of simple autoregressive models that we use, all of which can be esti-mated using least squares, across horizons ranging from one day to three months. We also present results on the informa- WebNov 27, 2013 · Barndorff-Nielsen, O.E. & Shephard, N. (2004) Power and bipower variation with stochastic volatility and jumps ...
