Pricing distressed CDOs with base correlation and stochastic recovery rates
In 2008 and 2009, the calibration of the standard Gaussian copula model for collateralised debt obligations has frequently broken down. To overcome that problem, Martin Krekel has embedded the model with correlated stochastic recovery rates. He shows…
Factors on demand
Attilio Meucci introduces a multi-asset-class return decomposition framework that extends beyond the standard systematic-plus-idiosyncratic approach. This framework, which rests on the conditional link between flexible bottom-up estimation factor models…
A dynamic model for leveraged funds
Guido Giese derives a model for the performance and Sharpe ratio of leveraged and inverse index funds that follow a dynamic leveraged trading strategy, that is, they are rebalanced on a daily basis to ensure a constant degree of leverage with respect to…
A bottom-up model with top-down dynamics
Yadong Li proposes a flexible, tractable and arbitrage-free bottom-up dynamic correlation modelling framework with a consistent stochastic recovery specification for multi-name credit derivatives. In this framework, the model’s spread dynamics can be…
The value of a variance swap – a question of interest
Pricing equity variance swaps is well understood in the case of deterministic interest rates, but particularly for longer-dated swaps the stochastic nature of the rate cannot be ignored. Here, Per Hörfelt and Olaf Torné derive the fair strike when both…
Roles of depositaries and custodians in a Ucits hedge fund framework
In the May issue we reported the results of a recent EDHEC-Risk Institute survey on structuring hedge fund strategies as Ucits.
