In this paper we survey some recent developments on risk measures for portfolio vectors and on the allocation of risk problem. The main purpose to study risk measures for portfolio vectors X = (X1, . . . , Xd) is to measure not only the risk of the marginals separately but to measure the joint risk of X caused by the variation of the components and their possible dependence. Thus an important p...

In investment market, investors often pay attention to investment portfolio selection and asset allocation under market risk. Thus, this study presents a two-stage method of investment portfolio based on soft computing techniques. The first stage uses data envelopment analysis to select most profitable funds, while hybrid of genetic algorithm (GA) and particle swarm optimization (PSO)is propose...

Capital allocation for credit portfolios has two meanings. First, at portfolio level it means to determine capital as a buffer against an unexpected negative cash-flow resulting from credit losses. In this case, the allocation method can be specified by means of a risk measure. Its result is called economic capital of the portfolio. Second, at sub-portfolio or transaction level, capital allocat...

This paper provides empirical evidence on life-cycle patterns in the asset allocation of Swedish households. Data on household portfolio allocation are collected from the HINK surveys for the period 1982-1992, and portfolio shares of different asset categories are regressed on age, period, and cohort dummies as well as socio-economic and demographic variables. There are evident differences in t...

The same effect is at work with portfolio optimizers that perform asset allocation and portfolio allocation chores. A small change to an input works its way through the system of equations and results in a large change in allocations. As a result, it is very easy to arrive at a set of "non-intuitive" allocations; i.e. they don't exhibit common sense. Once a set of portfolio allocations is put i...

This paper investigates the allocation decision of an investor who owns two projects, a domestic and a foreign one. A manager governs the expected return from each project, and the investor has less information on the actions of the foreign manager. The investor’s portfolio will be tilted relative to a situation with full information. With asymmetric information, he generally achieves a better ...
