From characteristic functions to implied volatility expansions [PDF]
For any strictly positive martingale $S = \exp(X)$ for which $X$ has a characteristic function, we provide an expansion for the implied volatility. This expansion is explicit in the sense that it involves no integrals, but only polynomials in the log ...

Investors’ net buying pressure and implied volatility dynamics
This study reexamines the influence of different investor types' net options demand on the KOSPI200 options-implied volatility dynamics. We extend Bollen and Whaley (2004) by accounting for options traders' hedging demand for futures contracts, intraday ...

INDIFFERENCE PRICES AND IMPLIED VOLATILITIES [PDF]
AbstractWe consider a general local‐stochastic volatility model and an investor with exponential utility. For a European‐style contingent claim, whose payoff may depend on either a traded or nontraded asset, we derive an explicit approximation for both the buyer's and seller's indifference prices.

Dynamic co-movements of stock market returns, implied volatility and policy uncertainty [PDF]
We examine time-varying correlations among stock market returns, implied volatility and policy uncertainty. Our findings suggest that correlations are indeed time-varying and sensitive to oil demand shocks and US recessions.

Jump-Robust Realized-GARCH-MIDAS-X Estimators for Bitcoin and Ethereum Volatility Indices
In this paper, we conducted an empirical investigation of the realized volatility of cryptocurrencies using an econometric approach. This work’s two main characteristics are: (i) the realized volatility to be forecast filters jumps, and (ii) the benefit ...

In this short note, we prove by an appropriate change of variables that the SVI implied volatility parameterization presented in Gatheral's book and the large-time asymptotic of the Heston implied volatility agree algebraically, thus confirming a ...

Using CAViaR models with implied volatility for value-at-risk estimation [PDF]
This paper proposes VaR estimation methods that are a synthesis of conditional autoregressive value at risk (CAViaR) time series models and implied volatility.

An Hilbert space approach for a class of arbitrage free implied volatilities models [PDF]
We present an Hilbert space formulation for a set of implied volatility models introduced in \cite{BraceGoldys01} in which the authors studied conditions for a family of European call options, varying the maturing time and the strike price $T$ an $K$, to
