Effcts of Diffrent Methods of Aggregation of Probabilities on the R&D Investment Portfolio for Optimal Emissions Abatement: An Empirical Evaluation
Probabilities on the R&D Investment Portfolio Optimal Emissions Abatement An Empirical Evaluation
2014/10/22
This thesis examines two possible orders of combining multiple experts in elicitations with multiple de-composed events: Should experts be combined early or later in the decision process? This thesis ...

Dynamic Portfolio Analysis and Its Application to the Problem of Export Diversification。
Saddlepoint methods in portfolio theory
Saddlepoint methods portfolio theory Portfolio Management
2012/3/2
We discuss the use of saddlepoint methods in the analysis of portfolios, with particular reference to credit portfolios. The objective is to proceed from a model of the loss distribution, given throug...
This paper addresses the optimal scheduling of the liquidation of a portfolio using a new
angle. Instead of focusing only on the scheduling aspect like Almgren and Chriss in [2], or
only on the liqu...
Optimal Portfolio Diversification Using Maximum Entropy Principle
Diversification Entropy measure Portfolio selection Shrinkage rule Simulation methods
2011/4/2
Markowitz’s mean-variance (MV) efficient portfolio selection is one of the most widely used approaches in solving portfolio diversification problem. However, contrary to the notion of diversification,...
Measuring Portfolio Diversification
diversification portfolio asset Gaussian assets the measure
2011/3/23
In the market place, diversification reduces risk and provides protection against extreme events by ensuring that one is not overly exposed to individual occurrences.
Portfolio Insurance under a risk-measure constraint
Portfolio insurance Utility maximization Convex risk measures CVaR entropic risk measure
2011/3/23
We study the problem of portfolio insurance from the point of view of a fund manager, who guarantees to the investor that the portfolio value at maturity will be above a fixed threshold.
Scaling portfolio volatility and calculating risk contributions in the presence of serial cross-correlations
portfolio market risk volatility scaling square-root-of-time rule
2010/10/21
In practice daily volatility of portfolio returns is transformed to longer holding periods by multiplying by the square-root of time which assumes that returns are not serially correlated. Under this ...
Optimal Liquidation Strategies Regularize Portfolio Selection
Optimal Liquidation Strategies Regularize Portfolio Selection
2010/10/19
We consider the problem of portfolio optimization in the presence of market impact, and derive optimal liquidation strategies. We discuss in detail the problem of finding the optimal portfolio under E...
Monte Carlo Portfolio Optimization for General Investor Risk-Return Objectives and Arbitrary Return Distributions: a Solution for Long-only Portfolios
Portfolio Optimization Optimisation Random Portfolio Monte Carlo Simplex
2010/10/21
We develop the idea of using Monte Carlo sampling of random portfolios to solve portfolio investment problems. In this first paper we explore the need for more general optimization tools, and conside...
Vast Volatility Matrix Estimation using High Frequency Data for Portfolio Selection
Minimum variance portfolio portfolio allocation risk assessment
2010/10/20
Portfolio allocation with gross-exposure constraint is an effective method to increase the efficiency and stability of selected portfolios among a vast pool of assets, as demonstrated in Fan et al (20...
Random Matrix Theory and Fund of Funds Portfolio Optimisation
Random Matrix Theory Hedge Funds Fund of Funds Correlation
2010/10/20
The proprietary nature of Hedge Fund investing means that it is common practise for managers to release minimal information about their returns. The construction of a Fund of Hedge Funds portfolio re...
Robust and Adaptive Algorithms for Online Portfolio Selection
Portfolio Selection Mean-Variance Portfolios Adaptive Filtering
2010/10/20
We present an online approach to portfolio selection. The motivation is within the context of algorithmic trading, which demands fast and recursive updates of portfolio allocations, as new data arrive...
The dual optimizer for the growth-optimal portfolio under transaction costs
The dual optimizer the growth-optimal portfolio transaction costs
2010/10/20
We consider the maximization of the long-term growth rate in the Black-Scholes model under proportional transaction costs as in Taksar, Klass and Assaf [Math. Oper. Res. 13, 1988]. Similarly as in Ka...
Portfolio optimization in a defaults model under full/partial information
Optimal investment default time default intensity filtering
2010/10/19
In this paper, we consider a financial market with assets exposed to some risks inducing jumps in the asset prices, and which can still be traded after default times. We use a default-intensity model...
