The purpose of this paper is to clarify some of the difficulties that a practitioner may find in implementing the binomial model for valuing a corporate bond with multiple embedded options in emerging markets. Especially, when faced with the dilemma of determining which should be the proxy...

Based on the fact that realized measures of volatility are affected by measurement errors, we introduce a new family of discrete-time stochastic volatility models having two measurement equations relating both observed returns and realized measures to the latent conditional variance. A...

This note is an answer the consultation published by ISDA regarding the amendment of documentation to implement fallbacks for certain key IBORs. The answers refer to many technical issues. More details about those issues can be found in the technical note 'A quant perspective on IBOR fallback...

Regulations impose idiosyncratic capital and funding costs for holding derivatives. Capital requirements are costly because derivatives desks are risky businesses; funding is costly in part because regulations increase the minimum funding tenor. Idiosyncratic costs mean no single measure makes...

This case addresses securities that allow the holders to acquire stock directly from the issuing corporation either by purchase (warrants) or by exchanging convertible debt of the corporation for its stock. One can deem warrants and convertible debt as two different types of the same category of...

This note analyses derivative pricing in the context of a collateral rate switch during the life of a financial product or the existence of two overnight rates. In particular we analyse the impact of forward change of collateral, the impact on OISs when the collateral rate is different from the...

Investment behaviour, techniques and choices have evolved in the options markets since the launch of options trading in 1973. Today, we are entering the field of Big Data and the explosion of information, which has become the main feature of science, impacts investors' decisions and their...

We consider a seasonal mean-reverting model for energy commodity prices with jumps and Heston-type stochastic volatility, as well as three nested models for comparison. By exploiting the affine form of the log-spot models, we develop a general valuation framework for futures and discrete...

In this article, the Universal Approximation Theorem of Artificial Neural Networks (ANNs) is applied to the SABR stochastic volatility model in order to construct highly efficient representations. Initially, the SABR approximation of Hagan et al. [2002] is considered, then a more accurate...

We apply the directed acyclic graph and spillover index models and find significant evidence of both implied volatility contagion and spillover. First, the global implied volatility smiles exhibit strong regional clustering. The European and American options markets form a separate contemporary...
