Time-inhomogeneous Gaussian stochastic volatility models: Large deviations and super roughness
نویسندگان
چکیده
We introduce time-inhomogeneous stochastic volatility models, in which the is described by a nonnegative function of Volterra type continuous Gaussian process that may have very rough sample paths. The main results obtained paper are path and small-noise large deviation principles for log-price super model under mild restrictions. use these to study asymptotic behavior binary barrier options, exit time probability functions, call options.

Large Deviations and Stochastic Volatility with Jumps: Asymptotic Implied Volatility for Affine Models
Let σt(x) denote the implied volatility at maturity t for a strike K = S0e , where x ∈ R and S0 is the current value of the underlying. We show that σt(x) has a uniform (in x) limit as maturity t tends to infinity, given by the formula σ∞(x) = √ 2 ( h(x) + (h(x)− x) ) , for x in some compact neighbourhood of zero in the class of affine stochastic volatility models. The function h∗ is the convex...
متن کاملStatistical Inference for Time - Inhomogeneous Volatility Models
This paper offers a new approach for estimating and forecasting the volatility of financial time series. No assumption is made about the parametric form of the processes. On the contrary, we only suppose that the volatility can be approximated by a constant over some interval. In such a framework, the main problem consists of filtering this interval of time homogeneity; then the estimate of the...
متن کاملSample Path Large Deviations and Optimal Importance Sampling for Stochastic Volatility Models
Sample path Large Deviation Principles (LDP) of the Freidlin-Wentzell type are derived for a class of diffusions which govern the price dynamics in common stochastic volatility models from Mathematical Finance. LDP are obtained by relaxing the non-degeneracy requirement on the diffusion matrix in the standard theory of Freidlin and Wentzell. As an application, a sample path LDP is proved for th...
متن کاملSuper-replication in Stochastic Volatility Models under Portfolio Constraints
We study a financial market with incompleteness arising from two sources: stochastic volatility and portfolio constraints. The latter are given in terms of bounds imposed on the borrowing and short-selling of a ‘hedger’ in this market, and can be described by a closed convex set K . We find explicit characterizations of the minimal price needed to super-replicate European-type contingent claims...
متن کاملStochastic Volatility Models with Transaction Time Risk
We provide a structural approach to disentangle Granger versus instantaneous causality effects from transaction durations to transaction prices. So far, in the literature, instantaneous causality effects have either been excluded or cannot be identified separately from Granger type causality effects. By giving explicit moment conditions for observed returns over (random) transaction duration in...
