Predicting the Global Minimum Variance Portfolio*

چکیده

We propose a novel dynamic approach to forecast the weights of global minimum variance portfolio (GMVP) for conditional covariance matrix asset returns. The GMVP are population coefficients linear regression benchmark return on vector differences. This representation enables us derive consistent loss function from which we can infer without imposing any distributional assumptions In order capture time variation in returns’ structure, model through recursive least squares (RLS) scheme as well by generalized autoregressive score (GAS) type dynamics. Sparse parameterizations and targeting toward equally weighted ensure scalability with respect number assets. apply these models daily stock returns, find that they perform compared existing static approaches terms both expected unconditional variance.

Bayesian estimation of the global minimum variance portfolio

In this paper we consider the estimation of the weights of optimal portfolios from the Bayesian point of view under the assumption that the conditional distribution of the logarithmic returns is normal. Using the standard priors for the mean vector and the covariance matrix, we derive the posterior distributions for the weights of the global minimum variance portfolio. Moreover, we reparameteri...

Mean - Variance Portfolio Optimisation

QP is the optimization of a quadratic function subject to linear equality and inequality constraints. It arises in multiple objective decision making where the departure of the actual decisions from their corresponding ideal, or bliss, value can be evaluated using a weighted quadratic norm as a measure of deviation. The formulation of mean-variance optimization of uncertain systems also leads t...

Linear statistical inference for global and local minimum variance portfolios

Traditional portfolio optimization has been often criticized since it does not account for estimation risk. Theoretical considerations indicate that estimation risk is mainly driven by the parameter uncertainty regarding the expected asset returns rather than their variances and covariances. This is also demonstrated by several numerical studies. The global minimum variance portfolio has been a...

The Influence of Changes in Asset Volatilities and Correlations on Minimum Variance Portfolio Risk

This paper makes a number of contributions to the understanding of minimum variance portfolio (MVP) risk. First, it presents several results connecting changes in MVP risk to changes in portfolio asset volatilities and correlations. Second, it explores the efficacy of three alternative methods of attributing changes in MVP risk to either changes in asset volatility or changes in asset correlati...

The Minimum Variance Unbiased Estimator

This module motivates and introduces the minimum variance unbiased estimator (MVUE). This is the primary criterion in the classical (frequentist) approach to parameter estimation. We introduce the concepts of mean squared error (MSE), variance, bias, unbiased estimators, and the bias-variance decomposition of the MSE. The Minimum Variance Unbiased Estimator 1 In Search of a Useful Criterion In ...
