First, we test the performance of the HAR model for the realized variation, which yielded the lowest forecasting power among all the candidate models when evaluated on the

The empirical results for three stocks traded on the New York Stock Exchange showed that the co-jumps of any two assets have a significant impact on future co-volatility, but that

Boudt and Zhang (2013) suggested a jump-robust TSRV (RTSRV) estimator as a mixture of the TSRV estimator in (6), and the truncated realized volatility estimators of Macini and Ren´

Volatility forecasting error for Macy’s (M) resulted in approximately $0.40 pricing error for both forecasting methods, with historical volatility overestimating the option

The TCC PC solenoid regulates actuator feed limit fluid pressure to the TCC regulator valve, located in the lower valve body, and provides a signal pressure to shift the TCC

Empirical results show that more than 80% of the co-volatility of the two futures contains jump variations and that they have significant impacts on future co-volatility but that

The primary objective of this retrospective cohort analysis was to compare health centers to hospitals in terms of adoption and adherence to new treatment guidelines, using as a

While bipower variation is a consistent estimator of integrated volatility as the time interval between observation vanishes, our simulation studies show that in finite samples it

Empirical results for daily crude oil and gold futures show that the co-jumps of the two futures have significant impacts on future co-volatility, but that the impact is negligible
