A study of the state of the theory of fuzzy sets shows that until recently in Russia there were almost no studies in the chemical sector of the economy and finance using fuzzy analysis and forecasting, although by that time all necessary prerequisites for modeling financial systems had been created. The current situation in Russia is characterized by a high degree of science lagging behind the requests of state and commercial supply chain management.

In this paper, we propose a method for risk measurement of a portfolio containing indexes on financial markets, including stock and foreign exchange markets. Specifically, copula method is applied to estimate the Value at Risk (VaR) and the Conditional Value at Risk (CVaR) of some optimal portfolios consisting Vietnam stock index VNINDEX, some international stock markets such as the USA, Chinese, Korean, Japanese, French, Australian markets and exchange rates.

The mining and energy sector is still the driving force for economic development and community empowerment, especially around mining and energy activities. Therefore, increased investment in the mining and energy sectors needs to be increased and balanced with stricter safety and environmental policies. This paper aims to formulate a quadratic investment portfolio optimization model, and apply it to several stocks in the mining and energy sectors.

The objective of this dissertation is to investigate that whether the investors can improve the performance of minimum – variance optimized portfolios by altering the estimators of covariance matrix input. Besides, based on the results of out – of – sample portfolio performance metrics, the dissertation is going to select the suitable estimators of covariance matrix for portfolio optimization on Vietnam stock market.

Stock market is an important capital mobilization channel for economy. However, the market has potential loss due to fluctuations of stock prices to reflect uncertain events such as political news, supply and demand of daily trading volume. There are many approaches to reduce risk such as portfolio construction and optimization, hedging strategies.

In this paper, employ asymmetric multivariate GARCH approaches to examine their performance on the volatility interactions between global crude oil prices and seven major stock market indices. Insofar as volatility spillover across these markets is a crucial element for portfolio diversification and risk management, we also examine the optimal weights and hedge ratios for oil-stock portfolio holdings with respect to the results.

Even though correlations between different economies’ stock markets have empirically increased over time, it would have been advantageously to invest in developing countries' stock markets such as the Indian stock market, instead of investing in the US-stock market when considering the overall market returns of the last decade. Anticipating beneficial asset allocations is challenging since higher returns are basically associated with higher risks. The estimation procedure which is employed in this study to construct globally invested portfolios is based on cointegration analysis.

This paper will discuss portfolio optimization, Quadratic Programming (QP) and Second Order Cone Programming (SOCP). We will use simulated and empirical data to compare the two optimization routines. Daily data for SP500 stocks from 2005 to 2010 was used to show that a 20-days rebalanced portfolio strategy with an expected portfolio return of 60 percent of the maximum expected return for all stocks produced an 8.4 percent return premium on an annual basis if we used QP and 11.2 percent return premium on an annual basis if we used SOCP.

The selection of optimal portfolios is the central problem of financial investment decisions. Mathematically speaking, portfolio selection refers to the formulation of an objective function that determines the weights of the portfolio invested in each asset as to maximize return and minimize risk. This paper applies the method of genetic algorithm (GA) to obtain an optimal portfolio selection. However, the GA parameters are of great importance in the procedure of convergence of this algorithm towards the optimal solution such as crossover.

Reviewing the basics of mean–variance portfolio optimization and the capital asset pricing model, this paper discusses the plausibility of some of the underlying assumptions. It is pointed out that a positive in-sample relationship between the expected return of an asset and its covariance with the market portfolio can be a statistical artifact because it can be explained without using any economic arguments. In an empirical analysis of two sets of assets consisting of individual stocks and indices, respectively, no indication of any out-of-sample relationship is found.

These new methods allow us to estimate the density of the portfolio which leads to calculations of some popular risk measurements like the value at risk (VaR) of investment portfolios. As for applications, making use of the listed stocks on the Ho Chi Minh city Stock Exchange (HoSE), some Markowitz optimal portfolios are constructed together with their risk measurements.

This study is to estimate risk tolerance of investors in HCMC Stock Exchange (HOSE) and then work out a portfolio optimization model on the basis of risk tolerance known. To do thus, questionnaires, Markowitz portfolio theory, and the capital asset pricing model (CAPM) will be employed in the research.

We propose a dynamic stochastic accumulation model for determining optimal decision between stock and bond investments during accumulation of pension savings. Stock prices are assumed to be driven by the geometric Brownian motion. Interest rates are modeled by means of the Cox-Ingersoll-Ross model. The optimal decision as a solution to the corresponding dynamic stochastic program is a function of the duration of saving, the level of savings and the short rate.

Single period market models are the most elementary market models. Only a single period is considered. The beginning of the period is usually denoted by the time t = 0 and the end of the period by time t = 1. At time t = 0 stock prices, bond prices,possibly prices of other financial assets or specific financial values are recorded and the financial agent can choose his investment, often a portfolio of stocks and bond. At time t = 1 prices are recorded again and the financial agent obtains a payoff corresponding to the value of his portfolio at time t = 1....

Asset allocation investigates the optimal division of a portfolio among different asset classes. Standard theory involves the optimal mix of risky stocks, bonds, and cash together with various subdivisions of these asset classes. Underlying this is the insight that diversification allows for achieving a balance between risk and return: by using different types of investment, losses may be limited and returns are made less volatile without losing too much potential gain.

The rest of the paper is organized as follows. Section I lays out the household’s consumption and portfolio choice problemwith a durable consumption good and derives the Euler equations. Section II describes the consumption data used in the empirical work. The service f low for durable goods (as defined in the national accounts) is more cyclical than the service f low for nondurable goods and services. The high cyclicality of the service f low, rather than durability of the good, is the key ingredient in explaining the known facts about expected stock returns....
