Optimization Method for Interval Portfolio Selection Based on Satisfaction Index of Interval inequality Relation
Interval portfolio selection satisfaction index semiabsolute deviation risk parametric linear programming
2012/9/14
In this paper we consider an interval portfolio selection problem with uncertain returns and introduce an inclusive concept of satisfaction index for interval inequality relatio...
On-Line Portfolio Selection with Moving Average Reversion
Portfolio Selection Moving Average Reversion
2012/9/14
On-line portfolio selection has attracted in-creasing interests in machine learning and AI communities recently. Empirical evidence show that stock’s high and low prices are temporary and stock price ...
Alpha Representation For Active Portfolio Management and High Frequency Trading In Seemingly Efficient Markets

2012/9/14
We introduce a trade strategy representation theorem for performance measurement and portable alpha in high fre-quency trading, by embedding a robust trading algorithm that describe portfolio manager ...
Portfolio optimization with insider's initial information and counterparty risk
asymmetric information enlargement of filtrations counterparty risk optimal investment duality dynamic programming.
2012/9/14
We study the gain of an insider having private information which concerns the default risk of a counterparty. More precisely, the default time τ is modelled as the first time a stochastic process hits...
Portfolio Choice with Transaction Costs: a User's Guide
transaction costs long-run, portfolio choice Merton problem.
2012/9/14
Recent progress in portfolio choice has made a wide class of problemsinvolving transaction costs tractable. We review the basic approach to these problems,and outline some directions for future resear...
The Long Neglected Critically Leveraged Portfolio
The Long Neglected Critically Leveraged Portfolio
2012/9/14
We show that the ecient frontier for a portfolio in which short positions precisely o set the long ones is composed of a pair of straight lines through the origin of the risk-return plane. This uniqu...
On the Exact Solution of the Multi-Period Portfolio Choice Problem for an Exponential Utility under Return Predictability
multi-period asset allocation expected utility optimization exponential utility func-tion return predictability.
2012/9/14
In this paper we derive the exact solution of the multi-period portfolio choice problem for an exponential utility function under return predictability. It is assumed that the asset returns depend on ...
On the Equivalence of Quadratic Optimization Problems Commonly Used in Portfolio Theory
investment analysis mean-variance analysis parameter uncertainty interval estimation test theory.
2012/9/14
In the paper, we consider three quadratic optimization problems which are frequently applied in portfolio theory, i.e, the Markowitz mean-variance problem as well as the problems based on the mean-var...
A Closed-Form Solution of the Multi-Period Portfolio Choice Problem for a Quadratic Utility Function
multi-period asset allocation quadratic utility function closed-form solution tan-gency portfolio
2012/9/14
In the present paper, we derive a closed-form solution of the multi-period portfolio choice problem for a quadratic utility function with and without a riskless asset. All results are derived under we...
Active Portfolio Management, Positive Jensen-Jarrow Alpha, and Zero Sets of CAPM
empirical alpha process portfolio hedging strategies active portfolio management market systemic risk swaption delegated portfo-lio management local time of alpha
2012/9/14
We present conditions under which positive alpha exists in the realm of active portfolio management– in contrast to the controversial result in (Jarrow, 2010, pg. 20) which implicates delegated portfo...
On the non-stationarity of financial time series: impact on optimal portfolio selection
non-stationarity of financial time series impact optimal portfolio selection Statistical Finance
2012/6/2
We investigate the possible drawbacks of employing the standard Pearson estimator to measure correlation coefficients between financial stocks in the presence of non-stationary behavior, and we provid...
Optimal execution of Portfolio transactions with geometric price process
Optimal execution Portfolio geometric price process
2010/11/2
In this paper we derive the Markowitz-optimal, deterministic-execution trajectory for a trader who wishes to buy or sell a large position of a share which evolves as a geometric Brownian
motion in co...
Simple heuristics for large portfolio choice in small samples are proposed. The loss of efficiency from true optimum is observed by simulation. The performance of chosen portfolios is reasonable when ...
