Secondly, we show a simple classification of the portfolio choices considering the asymptotic behavior of. We discuss the question of portfolio selection when the returns of the assets under consideration are characterized by a heavy-tailed distribution.
As distributional assumption we consider the sub-Gaussian stable model and address the problems of estimation and portfolio : Toker Doganoglu, Stefan Mittnik, Stefan Mittnik, Svetlozar Rachev, Svetlozar Rachev.
As empirical studies show, the daily returns of a bond and its credit spread obey a stable law, exhibiting peaked, heavy tailed, and skewed distributions. This implies the application of stable Credit Value-at-Risk (CVaR) in order to obtain a more precise measure for a bond’s risk compared to.

and portfolio allocation. Efficient frontier comprises investment portfolios that offer the highest expected return for a specific level of risk. Returns are dependent on the investment combinations that make up the portfolio.
Modern portfolio theory (MPT), or mean-variance analysis, is a mathematical framework for assembling a portfolio of assets such that the expected return is maximized for a given level of risk. It is a formalization and extension of diversification in investing, the idea that owning different kinds of financial assets is less risky than owning only one type.

Non normal returns and optimal portfolio allocation. If the returns are more heavy tailed than a normal distribution would imply, it may be more appropriate to reduce the allocation to the risky portfolio than you would under the.
Many financial decisions, such as portfolio allocation, risk management, option pricing and hedge strategies, are based on forecasts of the conditional variances, covariances and correlations of financial returns. The paper shows an empirical comparison of several methods to predict one-step-ahead conditional covariance matrices.

Since MPT's introduction inmany attempts have been made to improve the model, especially by. Data sets with low kurtosis tend to have light tails, or lack of outliers. In computing kurtosis the formula used is μ4/σ4 where μ4 is Pearson’s fourth moment about the mean and sigma is the standard deviation.
The normal distribution (Gaussian) is found to have a kurtosis of three. The formula μ4/σ4 - 3 is the formula for excess. "Portfolio Allocation with Heavy Tailed Returns" (with Divyajyoti Bhoumick and Bharathy Subramaniam) () appeared in the journal Applied Financial Economics Letters, vol 4, issue 3, "Artificial Neural Network Models for Forecasting Stock Price Index in Bombay Stock Exchange" (with Neeraj Mohan, Pankaj Jha and Goutam Dutta)( The literature on portfolio selection and risk measurement has considerably advanced in recent years.
The aim of the present paper is to trace the development of the literature and identify areas that require further research. This paper provides a literature review of the characteristics of financial data, commonly used models of portfolio selection, and portfolio risk by: 2.
The valuation of a portfolio, regardless of the method chosen, is always for the same purpose- to determine which portfolio yields the minimum risk or maximizes returns.
The main purpose of this paper is to determine which portfolios, constructed from stocks from KSE, would be most risky and which ones would be least risky.
It is sufficient to assume non-normal (unconditional) returns to explain the difference between monthly and daily estimates of annualized volatility. If you assume conditionally normal returns with stochastic volatility you have GARCH models; if the conditional returns are heavy-tailed, you have Levy process.
Portfolio modeling with heavy tailed random vectors by Mark M. Meerschaert, Hans-Peter Scheffler - Handbook of Heavy-Tailed Distributions in Finance, Since the work of Mandelbrot in the ’s there has accumulated a great deal of empirical evidence for heavy tailed models in finance.
If you had a portfolio of 30 equally weighted assets, and these assets would give you income streams 60% correlated with each other and each stream had a Sharpe ratio — the expected excess rate of return divided by its standard deviation— ofthen the portfolio Sharpe ratio would be: Sharpe_c = n*/(n + 2*n(n − 1)/2 *)^ = The Theory and Practice of Investment Management: Asset Allocation, Valuation, Portfolio Construction, and Strategies by Frank J.
