Extension of SABR Libor Market Model to handle negative interest rates

open access: yesQuantitative Finance and Economics, 2020
Variations of Libor Market Model (LMM), including Constant Elasticity of Variance-LMM (CEV-LMM) and Stochastic Alpha-Beta-Rho LMM (SABR-LMM), have become popular for modeling interest rate term structure.

Short-dated smile under rough volatility: asymptotics and numerics [PDF]

open access: yesQuantitative finance (Print), 2020
In Friz et al. [Precise asymptotics for robust stochastic volatility models. Ann. Appl. Probab, 2021, 31(2), 896–940], we introduce a new methodology to analyze large classes of (classical and rough) stochastic volatility models, with special regard to ...

Approaches to forecasing option volatility

open access: yesВестник Российского экономического университета имени Г. В. Плеханова, 2018
The article investigates a new approach to the idea of volatility. In spite of the well-known assumption that option volatility in future will be exactly the same as today, the author puts forward a method, which links the change in volatility to change ...

Option Pricing under the Jump Diffusion and Multifactor Stochastic Processes

open access: yesJournal of Function Spaces, 2019
In financial markets, there exists long-observed feature of the implied volatility surface such as volatility smile and skew. Stochastic volatility models are commonly used to model this financial phenomenon more accurately compared with the conventional

A Solution to the Time-Scale Fractional Puzzle in the Implied Volatility

open access: yesFractal and Fractional, 2017
In the option pricing literature, it is well known that (i) the decrease in the smile amplitude is much slower than the standard stochastic volatility models and (ii) the term structure of the at-the-money volatility skew is approximated by a power-law ...

From characteristic functions to implied volatility expansions [PDF]

open access: yes, 2014
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 ...

Realizing Smiles: Options Pricing with Realized Volatility [PDF]

open access: yesSSRN Electronic Journal, 2011
We develop a discrete-time stochastic volatility option pricing model exploiting the information contained in the Realized Volatility (RV), which is used as a proxy of the unobservable log-return volatility. We model the RV dynamics by a simple and effective long-memory process, whose parameters can be easily estimated using historical data.
