Crunching mortality and life insurance portfolios with extended CreditRisk+
Jonas Hirz, Uwe Schmock and Pavel Shevchenko present a summary of actuarial applications of the extended CreditRisk+ model
Beat equal weighting: a strategy for portfolio optimisation
Yong (Jimmy) Jin and Lie Wang propose an estimation method for optimal portfolio weights under parameter uncertainty
Adjusting VAR to correct sample volatility bias
David Frank proposes an adjustment to sample variance for the computation of value-at-risk

Johnson-Omega performance measure
Alexander Passow presents a portfolio performance measure that combines the omega measure with Johnson distributions
Risk management for return enhancement
Lundin and Satchell present a non-linear asymmetric dependence method between two assets
Hedging error measurement for imperfect strategies
Jack Baczynski, Jonathan da Silva and Rosalino Junior present an index for measuring hedging errors
Isolating a risk premium on the volatility of volatility
Lorenzo Ravagli shows how to exploit a risk premium embedded in the vol of vol in out-of-the-money options
Risk budgeting and diversification based on optimised uncorrelated factors
Meucci, Santangelo and Deguest introduce a risk decomposition method based on minimum-torsion bets
Stress testing in non-normal markets via entropy pooling
Ardia and Meucci introduce a parametric entropy pooling approach to portfolios stress testing

Multiperiod portfolio selection and Bayesian dynamic models
Kolm and Ritter present a multiperiod, multi-asset selection model with transacion costs, kept computationally tractrable
Optimal trading under proportional transaction costs
The theory of optimal trading under proportional transaction costs has been considered from a variety of perspectives. In this paper, Richard Martin shows that all results can be interpreted using a universal law through trading algorithm design
Optimal execution with a price limiter
Balancing the price uncertainty and price impact of large orders is an important issue for many market participants. While classical approaches lead to trading algorithms that are invariably price-path insensitive, in this article, Sebastian Jaimungal…
