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.
Questions abound over Ucits hedge funds
The directive on alternative investment fund managers (AIFM) will not necessarily allow professional investors to buy the funds offered to them. Controversy around the directive, together with uncertainty about the distribution of funds it will allow,…
Expanded smiles
Implementing models with stochastic as well as deterministic local volatility can be challenging. Here, Jesper Andreasen and Brian Huge describe an expansion approach for such models that avoids the high-dimensional partial differential equations usually…
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…
Beyond diversification: absolute return funds of ETFs
In the March article we drew on a recent Edhec-Risk Institute publication on risk control through dynamic core-satellite portfolios of exchange traded funds (ETFs) supported by Amundi (1) to look at the dynamic core-satellite approach to risk management…
Cutting Edge: Pure jump models for energy prices
Université de Lausanne’s Roberto Marfè investigates pure jump processes as modelling blocks for the distributions of energy returns under the pricing measure. An easy-to-implement option-implied approach is outlined, which circumvents most of the…
Fast correlation Greeks by adjoint algorithmic differentiation
Adjoint methods have recently been proposed as an efficient way to calculate risk through Monte Carlo simulation. Luca Capriotti and Mike Giles extend these ideas and show how adjoint algorithmic differentiation allows for fast calculation of price…
A dynamic model for correlation
Equity markets have experienced a significant increase in correlation during the crisis, resulting in exotic derivatives portfolios realising large losses. As larger correlations in downward scenarios are already implied in the index option market in the…
