The possibility to minimize volatility, while maximizing returns, is the use of an optimized buy long/sell short strategy that takes into account, that the market model is kinky. The equation of the market model - extendet by a parameter gamma - seems to be more qualified for this reason. An...

Along with the ongoing effort to build market cap-independent portfolios, the authors explore the properties of Diversification as a driver for portfolio construction. They introduce a measure of the diversification of portfolios that they term the “diversification ratio”. The measure is...

Downside and deviation risk measures are becoming more and more important in many disciplines with clear interfaces with Applied Mathematics and Operations Research. Their dual representations have played critical roles in most of their applications (risk management, portfolio selection, pricing...

In recent years many US corporate pension plans have closed and entered their “end-state.” As end-state plans have become more prevalent, their special portfolio management challenges, including asset allocation, have gained attention.Pure immunization with public fixed income assets...

Pooled annuity products, where the participants share systematic and idiosyncratic mortality risks as well as investment returns and risk, provide an attractive and effective alternative to traditional guaranteed life annuity products. While longevity risk sharing in pooled annuities has...

We study utility indifference pricing of untradeable assets in incomplete markets using a symmetric asymptotic hyperbolic absolute risk aversion (SAHARA) utility function, both from the buyer's and seller's perspective. The use of the SAHARA utility function allows us to tackle the ``short...

With-profit life insurance contracts are designed with a return smoothing collective savings component sharing the investment risks amongst different generations of policyholders. We analyze the resulting implications from the point of view of a multi-asset mean-variance investor by evaluating...

Longevity risk is the risk that the promised recipient of lifetime cashflows ends up living much longer than originally anticipated, thus causing a shortfall in funding. A related risk, reimbursement risk is the risk that providers of health insurance face when new and expensive drugs are...

Historical VaR, CVaR and ES (Expected Shortfall) to LIQUIDATION Software is a model characterized by its straightforwardness, allowing regulators measure risk using a standard database of primitive factors and portfolio positions only, leaving little error margin in comparing market risk for...

The Solvency II framework challenges insurers to evaluate and manage their embedded balance sheet risks appropriately. However, insurances hold balance sheet items, for which closed-form solutions and market prices are not available. Pure Monte Carlo valuation requires nested simulations, which...
