Nettettion of integrated volatility was considered by Fan and Wang (2007), and Podolskij and Vetter (2009b) using two fundamen-tally different techniques, which differ in the order of treating jumps and noise. Rosenbaum (2009) also considered the inte-grated volatility estimation under round-off error using wavelet approach.

NettetWe provide an asymptotic theory for the estimation of a general class of smooth nonlinear integrated volatility functionals. Such functionals are broadly useful for measuring financial risk and estimating economic models using high-frequency transaction data. The theory is valid under general volatility dynamics, which accommodates both … NettetExplanation. Implied volatility (IV) measures the likelihood of a change in the price of a security. It helps investors where their investment will move in the future by forecasting the supply & demand and the security price movement, which in turn helps to understand the price of options contracts. It is based on certain factors (which include ...

Nettet11. mar. 2024 · This paper is concerned with the problem of the estimation of the integrated volatility of log-prices based on high frequency data when both price jumps and market microstructure noise are present. We begin by providing a survey of the leading estimators introduced in the literature to tackle volatility estimation in this setting.
