The change subsequent to the sub-prime crisis pushed pressure on decreased financial products complexity, going from exotics to vanilla options but increase in pricing efficiency. We introduce in this paper a more efficient methodology for vanilla option pricing using a scenario based particle...

A mathematical and a market argument on the sub-linearity of the wings for the implied variance is given. Gatheral stochastic volatility inspired (SVI) parameterization claim to have two key properties that have led to its subsequent popularity with practitioners is exposed. Namely the linearity...

The aim of this article is to address the methodology behind de-arbitraging a realistic volatility surface and stressing it without adding arbitrages. We derive from basic principles the constraints which the changes on the strike and the tenor axis must satisfy in order to make a volatility...

The aim of this article is to introduce a new parametrization of the implied volatility surface (IVP), which builds on the gSVI methodology recently introduced but incorporates novel features like a bid-ask model and the methodology behind de-arbitraging a volatility surface and stressing it...

While time series momentum is a well-studied phenomenon in finance, common strategies require the explicit definition of both a trend estimator and a position sizing rule. In this paper, we introduce Deep Momentum Networks -- a hybrid approach which injects deep learning based trading rules into...
