CVI is an algorithm for constructing implied volatility surfaces that is framed as a convex optimisation problem. As such, it is suitable to be processed by modern optimisation solvers like CVXPY, ...
We extend the existing small-time asymptotics for implied volatilities under the Heston stochastic volatility model to the multifactor volatility Heston model, which is also known as the Wishart ...
Stochastic volatility models have revolutionised the field of option pricing by allowing the volatility of an asset to vary randomly over time rather than remain constant. These models have ...
