Optimal Investment of DC Pension Plan Under Short-Selling Constraints and Portfolio Insurance

Portfolio delegation under short - selling constraints ∗

In this paper we study delegated portfolio management when the manager’s ability to short-sell is restricted. Contrary to previous results, we show that under moral hazard, linear performance-adjusted contracts do provide portfolio managers with incentives to gather information. The risk-averse manager’s optimal effort is an increasing function of her share in the portfolio’s return. This resul...

portfolio optimization in terms of justifiability short selling and some market practical constraints

short-selling prohibition has been one of the primary assumptions of markowitz mean-variance model. solving markowitz quadratic model creates investment efficient frontier by considering only two return and budget constraints. in order to develop a more realistic portfolio selection model, in this paper, a new mathematical model is developed to allow short-selling under some practical constrain...

A duality method for optimal consumption and investment under short-selling prohibition

Growth-Optimal Portfolio Selection under CVaR Constraints

Online portfolio selection research has so far focused mainly on minimizing regret defined in terms of wealth growth. Practical financial decision making, however, is deeply concerned with both wealth and risk. We consider online learning of portfolios of stocks whose prices are governed by arbitrary (unknown) stationary and ergodic processes, where the goal is to maximize wealth while keeping ...

Optimal investment strategy to minimize the ruin probability of an insurance company under borrowing constraints

We consider that the reserve of an insurance company follows a Cramér-Lundberg process. The management has the possibility of investing part of the reserve in a risky asset. We consider that the risky asset is a stock whose price process is a geometric Brownian motion. Our aim is to find a dynamic choice of the investment policy which minimizes the ruin probability of the company. We impose tha...
