This paper investigates the impact of multiplicative background risk on an investor's portfolio choice in a mean-variance framework. We also study the efficient boundary frontiers with and without risk-free security.

This paper investigates the impact of background risk on an investor’s portfolio choice in a mean-VaR, mean-CVaR and mean-variance framework, and analyzes the characterizations of the mean-variance boundary and mean-VaR efficient frontier in the presence of background risk. We also consider...

Empirical evidence suggests that asset returns correlate more strongly in bear markets than conventional correlation estimates imply. We propose a method for determining complete tail-correlation matrices based on Value-at-Risk (VaR) estimates. We demonstrate how to obtain more efficient...

Since the enactment of Pension Protection Act of 2006, lifecycle funds that reduce exposure to stocks with age have rapidly replaced money market funds as the most commonly nominated default investment options for participant-directed retirement plans. We examine their appropriateness in meeting...

We prove a formula for the computation of optimal financial investments in an expected utility framework with arbitrary (not necessarily concave) utility functions. This extends classical results on optimal financial investments for strictly concave utility functions and is of importance...

Mutual Funds are the most common form of investment for the average household. They offer a fair amount of return for a limited amount of risk. Segregated Funds, which are, simply put, mutual funds with additional features, have grown in popularity as of late. It is something of great interest...

A model of bank’s dynamic asset management problem in case of partially observed future economic conditions and requirements concerning level of risk taken has been built. It requires solving the resulting optimal control with random terminal condition resulting from partial observation of...

This paper evaluates the effects of imposing Value-at-Risk (VaR) limits and quantitative restrictions on portfolio choices in the context of a risk-based supervision framework for defined contribution pension funds. It shows the conditions under which VaR constraints are equivalent to...

The management of financial risks, which is a branch of financial theory, is defined as a process that begins with risk factors identification, continues with measurement of risk and concludes with the coverage of that risk. This work focuses on the second phase of management process, namely the...

Conditional Value-at-Risk (CVaR) measures the expected loss amount beyond VaR. It has vast advantage over VaR because of its property of coherence. This paper gives an analytical solution in a complete market setting to the risk reward problem faced by a portfolio manager whose portfolio needs...
