Asset Allocation in the Presence of Uncertainty
ثبت نشده
چکیده
Return, risk and correlation estimates are fraught with uncertainty (the inability to know whether our estimates are correct, even if our method of estimation is unbiased). Diversification, while always desirable, is especially valuable in the presence of uncertainty. In fact, uncertainty can render diversification a more ―optimal‖ solution than traditional mean-variance optimization. This is why we pursue diversification in all market environments and why we maintain balanced portfolios, regardless of recent returns.

Asset Allocation under Multivariate Regime Switching
This paper studies asset allocation decisions in the presence of regime switching in asset returns. We find evidence that four separate regimes characterized as crash, slow growth, bull and recovery states are required to capture the joint distribution of stock and bond returns. Optimal asset allocations vary considerably across these states and change over time as investors revise their estima...
متن کاملOptimal portfolio allocation for pension funds in the presence of background risk
We model the asset allocation decision of a defined benefit pension fund in the UK using a stochastic dynamic programming approach. Our model recognizes the fact that asset allocation decisions are made by trustees who are mandated to act in the best interests of beneficiaries not by sponsoring employers and that trustees face payoffs that are linked in an indirect way to the value of the under...
متن کاملStock Return Predictability, Conditional Asset Pricing Models and Portfolio Selection
I examine an investor’s portfolio allocation problem across multiple risky assets in the presence of return predictability when, in addition to the predictability evidence, the investor uses conditional asset pricing models to guide him in the portfolio selection decision. I also explore how the uncertainty associated with the model dynamics affects the investor’s optimal portfolio. To analyze ...
متن کاملRobust Asset Allocation
This article addresses the problem of finding an optimal allocation of funds among different asset classes in a robust manner when the estimates of the structure of returns are unreliable. Instead of point estimates used in classical mean-variance optimization, moments of returns are described using uncertainty sets that contain all, or most, of their possible realizations. The approach present...
متن کاملA Robust Knapsack Based Constrained Portfolio Optimization
Many portfolio optimization problems deal with allocation of assets which carry a relatively high market price. Therefore, it is necessary to determine the integer value of assets when we deal with portfolio optimization. In addition, one of the main concerns with most portfolio optimization is associated with the type of constraints considered in different models. In many cases, the resulted p...
