Bipower volatility
WebKeywords: Bipower variation; Cojumping; Covariation; Jump process; Quadratic covaria-tion; Realised variance; Semimartingales; Stochastic volatility. 1 Introduction In the theory of nancial economics the variation of asset prices is measured by looking at sums of outer products of returns calculated over very small time periods. WebDec 1, 2010 · Threshold bipower variation has a bias of −4.15% in the case of no jumps, of −4.83% with a single jump, of −5.65% in the case of two jumps, and of −4.70% in the case of two consecutive jumps. When estimating quarticity, these biases range between −9% and −15% according to the number of jumps and the estimator used.

WebAbstract. This paper shows that realised power variation and its extension we introduce here called realised bipower variation is somewhat robust to rare jumps. We show realised bipower variation estimates integrated variance in SV models --- thus providing a model free and consistent alternative to realised variance.

For this class, it is possible to extend the quadratic variation process to the power variation process, which allows us to derive the probability limit of realized power variation. Finally, we introduce the idea of bipower variation and study …
WebSummary. 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. Given high frequency data we can use the concept of power and multipower variation ...

WebDec 8, 2006 · We propose a new concept of modulated bipower variation for diffusion models with microstructure noise. We show that this method provides simple estimates for such important quantities as integrated volatility or integrated quarticity. Under mild conditions the consistency of modulated bipower variation is proven. fluran hortumWebDec 1, 2010 · Threshold bipower variation has a bias of −4.15% in the case of no jumps, of −4.83% with a single jump, of −5.65% in the case of two jumps, and of −4.70% in the … flu questions and answersWebApr 13, 2024 · Portfolio optimisation is a core problem in quantitative finance and scenario generation techniques play a crucial role in simulating the future behaviour of the assets that can be used in allocation strategies.
