Estimation of the instantaneous volatility and detection of volatility jumps
Concerning price processes, the fact that the volatility is not constant has been observed for a long time. So we deal with models as dXt = μtdt + σtdWt where σ is a stochastic process. Recent works on volatility modeling suggest that we should incorporate jumps in the volatility process. Empirical observations suggest that simultaneous jumps on the price and the volatility [8, 9] exist. The hy...
متن کاملExchange rate volatility and its effect on stock market volatility
This paper investigates empirically the effect of volatility of the exchange rate of the U.S. dollar vis-à-vis the euro on U.S. stock market volatility while controlling for a number of drivers of stock return volatility. Using a GARCH(1, 1) model and using weekly data covering the period from the week of January 1, 1999 through the week of January 25, 2010, it is found that the 9/11 terrorist ...
متن کاملModeling Volatility Spillovers in Iran Capital Market
This paper investigates the conditional correlations and volatility spillovers between the dollar exchange rate return, gold coin return and crude oil return to stock index return. Monthly returns in the 144 observations (2005 - 2017) are analyzed by constant conditional correlation, dynamic conditional correlation, VARMA-GARCH and VARMA-AGARCH models. So this paper presents interdependences in...
متن کاملUnderstanding Stock Market Volatility
One of the most prominent features of the U.S. stock market is the close connection between aggregate stock market volatility and the development of the business cycle. Figure 1 depicts the statistical relation between stock market volatility and the industrial production growth rate over the last sixty years, which shows that stock volatility is largely countercyclical, being larger in bad tim...
متن کاملNon-Parametric Estimation of Intraday Spot Volatility: Disentangling Instantaneous Trend and Seasonality
We provide a new framework for modeling trends and periodic patterns in high-frequency financial data. Seeking adaptivity to ever-changing market conditions, we enlarge the Fourier flexible form into a richer functional class: both our smooth trend and the seasonality are non-parametrically time-varying and evolve in real time. We provide the associated estimators and use simulations to show th...
