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 ...
Time-Consistent Mean-Variance Portfolio Selection in Discrete and Continuous Time
mean-variance criterion Markowitz problem portfolio optimisation time consistency time-inconsistent optimal control
2012/6/5
It is well known that mean-variance portfolio selection is a time-inconsistent optimal control problem in the sense that it does not satisfy Bellman's optimality principle and therefore the usual dyna...
