Modeling the Dynamics of Correlations among Implied Volatilities
Review of Finance, 2012Abstract Implied volatility (IV) reflects both expected empirical volatility and also risk premia. Stochastic variation in either creates unhedged risk in a delta hedged options position. We develop EGARCH/DCC models for the dynamics of volatilities and correlations among daily IVs from options on twenty-eight large cap stocks.

Introduction In previous chapters we have introduced and analysed the standard market model for valuing synthetic CDOs. In this and the next chapter we examine the natural consequences of what happens when a bespoke, illiquid market becomes standardised and highly liquid.

Applied Economics Letters, 2016ABSTRACTImplied volatility indices are an important measure for ‘market fear’ and well-known in academia and practice. Correlation is still paid less attention even though the CBOE started to calculate implied correlation indices for the S&P500 in 2009.

Central Bank Interventions and Implied Exchange Rate Correlations
SSRN Electronic Journal, 2006Abstract This paper examines the effects of the foreign exchange market interventions by the Bank of Japan on the ex ante correlations between the JPY/USD, EUR/USD, and GBP/USD exchange rates.

Investigating Dynamic Correlation in the International Implied Volatility Indexes
2018This paper investigates dynamic interaction among international volatility indexes, consisting of VIX, VSTOXX, VDAX, VFTSE, VNVIXN, VHSI and VKOSPI. This paper also extends the multivariate normal distribution and multivariate student-t distribution based dynamic conditional correlation (DCC) model to a multivariate skew distribution.

, 2013 Certain financial instruments provide information on expectations of future interest rate movements. One relatively new instrument is yield curve options, which allow investors to take financial positions on a range of possible future interest rates. These options can shed light on the views of financial markets regarding future monetary policy at a ...
