Opis:
Portfolio analysis is a tool particularly intended for investors. Risk assessment and risk specification make the investor able to properly diversify and offset the portfolio. Broadly speaking, there are multiple tools destined for building up an efficient set of portfolios. One of them is Markowitz’s model theory postulating building up a portfolio determined on the basis of equilibrium between expected profit level as well as accepted level of risk assessment. In the context of this paper, the objective is to shed some light on creating investment portfolios based on either Markowitz's portfolio theory or evolutionary algorithm. The simulation based methods for building up a portfolio of approximately 40-50 companies listed out in the primary marketof the Warsaw Stock Exchange using the selection function proposed in the BA thesis were presented. Portfolio profit values have been evaluated in a dynamically shifted time window. The conducted analysis showed shifts in the economy at certain periods of time. The implemented genetic algorithms smoothly handled the optimization with a relatively short processing time of the task result.

Opis:
In today’s globalized world, investing is a key financial management strategy related to the hope of obtaining future economic benefits. Access to more and more information has created new opportunities for wealth creation, including investments in stocks, cryptocurrencies, gold, real estate and many other assets. The work emphasizes the importance of investing and diversifying the investment portfolio, especially in periods of inflation, using the example of a portfolio of listed companies compared to a currency portfolio. The study covers the period from December 2019 to December 2020, and the analysis aims to estimate the rate of return on investment based on the Markowitz and CAPM theories. The presented analysis method is applicable both in the academic environment and in real economic scenarios, encouraging further research on investments.

Opis:
The study entitled Analysis of Foreign Currency Portfolio In Indonesia is a case study of a foreign exchange market portfolio taking a research site at Bank Indonesia. Markowitz was the first to introduce the concept of portfolio risk, which in general risk can be reduced by combining multiple assets into a portfolio or so-called diversification. This research was conducted to analyze the optimal portfolio of foreign exchange investment in order to make investments give maximum return and certain risk that is obtained optimally. Based on the results of the research of the four currencies used as sample analysis, the four currencies can form as optimal portfolio of CHF, CNY, GBP and JYP, while the highest rate of return using portfolio theory is in Chinese Yuan (CNY) by 71%. The expected return of the currency is dominating compared to other foreign currencies.

Subject and purpose of work: The purpose of this work was to compare selected portfolio strategies in terms of return rates in order to answer the question whether the method of determining the weights of the portfolio and reduction of the number of portfolio elements characterized by strong positive correlation of rates of return have an impact on its profitability. Materials and methods: The analysis used publicly available data, selected portfolio methods and hierarchical clustering. Both short- and long-term investment strategies were examined. Results: None of analyzed strategies allows to achieve higher rates of return in any given (arbitrarily selected) period than other analyzed strategies. Portfolios with a reduced number of elements in most cases did make it possible to achieve a higher rate of return than the benchmark portfolios consisting of 15 cyptocurrencies. Conclusions: While making investment decisions, one should bear in mind that the realized rate of return may significantly differ from the expected rate of return of the portfolio, which is only a forecast.

Opis:
The main goal of this research is to analyse the investment benefits from an incorporation of the volatility exposure to the diversified portfolio from the perspective of a Polish investor. Volatility, treated as a new asset class, may improve the performance of the portfolio due to its negative correlation with most types of assets. This topic has been widely investigated for the United States and Europe whereas the Polish market appears to be not heavily researched and this study may fill this gap. The research covers the period from October 2010 to July 2018 and is performed on daily close prices. To construct the portfolios the analysis uses the mean-variance framework and the naïve diversification approach. The comparison of risk-adjusted returns between investments with and without volatility exposure enables an answer to the research question about an improvement of the results by the addition of a non-standard asset to the diversified portfolios. The VXX is considered as the proxy for volatility as it is the most popular ETN which follows the volatility index derivatives with the given maturity. To test the robustness of the results the portfolios are constructed with a broad range of different parameters and assumptions imposed on the optimization procedure.

The classical Markowitz approach to portfolio selection leads to a biobjective optimization problem where the objectives are the expected return and the variance of a portfolio. In this paper a biobjective dual optimization problem to the Markowitz portfolio optimization problem is introduced and analyzed. For the Markowitz problem and its dual, weak and strong vector duality assertions are derived. The optimality conditions are also verified.

Opis:
The mean-variance approach to portfolio investment exploits the fact that the diversification of investments by combination of different assets in one portfolio allows for reducing the financial risks significantly. The mean-variance model is formulated as a bi-objective optimization problem with linear (expected return) and quadratic (variance) objective functions. Given a set of available assets, the investor searches for a portfolio yielding the most preferred combination of these objectives. Naturally, the search is limited to the set of non-dominated combinations, referred to as the Pareto front. Due to the globalization of financial markets, investors nowadays have access to large numbers of assets. We examine the possibility of reducing the problem size by identifying those assets, whose removal does not affect the resulting Pareto front, thereby not deteriorating the quality of the solution from the investor’s perspective. We found a sufficient condition for asset redundancy, which can be verified before solving the problem. This condition is based on the possibility of reallocating the share of one asset in a portfolio to another asset without deteriorating the objective function values. We also proposed a parametric relaxation of this condition, making it possible to removemore assets for a price of a negligible deterioration of the Pareto front. Computational experiments conducted on five real-world problems have demonstrated that the problem size can be reduced significantly using the proposed approach.

Opis:
This paper addresses an approach for solving multicriteria portfolio investment problem. The original Markowitz mean-variance model is formulated as a problem of bi-objective optimization with linear and quadratic objective functions. In the current work, this model is extended by introducing a new objective, reflecting asset properties that are useful for the portfolio allocation process. A method based on parameterized achievement scalarizing function is applied to produce Pareto optimal portfolios. A mathematical programming formulation that allows for solving the problem with conventional optimization methods is presented. In addition, a method of reflecting the decision maker’s preferences by means of changing the weights in the achievement scalarizing functions is introduced. A decision making process is simulated for the three-objective portfolio optimization problem.

Financial liquidity interconnections are close to be a portfolio investment problem. The following article is a result of the Slovak–Polish cooperation, between partners from University of Economics in Bratislava and Wroclaw University of Economics. We have created a set of three programs in MS Excel which calculate the approximation of the border of the investment opportunities. The applications are continually developed. All programs are written in VBA for Excel. The following article introduces the second and the third program in which we have coded the fundaments of the portfolio selection to the VBA Excel. Their names are FINV and IDPORT. The FINV calculates the border of investment opportunities by using matrix algebra. FINV works with the enabled short sales. IDPORT calculates the border of investment opportunities by using SOLVER, which is the optimization library. The software has many settings which will be described in the article. It demonstrates the fundaments of the theory of investment portfolio and it is suitable for the teaching purposes at this stage of the development.

Opis:
W pracy rozważano portfele Markowitza, dla których charakterystyki aktywów składowych szacowano odpornymi metodami MVE oraz MCD, a także podejściem Blacka-Littermana, gdzie rozkład a priori specyfikowano na podstawie prognoz wykorzystujących wyniki badań ankietowych koniunktury. Na podstawie dziennych stóp zwrotu z indeksów sektorowych GPW obejmujących lata 2007-2013 analizowano empiryczne własności rozważanych portfeli. Pokazano, że metoda MVE generuje portfele bardzo konserwatywne, natomiast MCD - agresywne, niezależnie od przyjętych wartości punktów załamania. Uwzględnienie dodatkowo rozkładów a priori w podejściu Blacka-Littermana miało jedynie ograniczony wpływ na wyniki. Pokazano także, że korzystanie z wyników badań ankietowych koniunktury w klasycznym podejściu Blacka-Littermana jest uzasadnione przy dłuższych szeregach czasowych, na podstawie których były generowane prognozy stóp zwrotu aktywów składowych portfeli.
The paper discusses Markowitz portfolios where asset characteristics were estimated with robust MVE and MCD procedures as well as Black-Litterman method with business tendency survey results employed to specify a priori distributions. Using daily returns on sector stock indices from Warsaw Stock Exchange spanning the period 2007-2013 empirical performance of the portfolios were examined. It is shown that MVE portfolios were extremely conservative, whereas MCD - very aggressive regardless of the estimator's breakdown points. Incorporating additional a priori knowledge hardly affected the results. Additionally it is documented that including data from the business tendency surveys may improve the portfolio characteristics provided sufficiently long time series are used to forecast the asset returns.3

Opis:
We examine two investment algorithms built on the weekly data of world equity indices for emerging and developed countries in the period 2000-2015. We create seven risk factors using additional data about market capitalization, book value, country GDP and betas of equity indices. The first strategy utilizes the theoretical value of equity risk premium from the seven-factor Markov-switching model with exogenous variables. We compare theoretical with the realized equity risk premium for a given index to undertake the buy/sell decisions. The second algorithm works only on eight risk factors and applies them as input variables to Markowitz models with alternative optimization criteria. Finally we note that the impact of risk factors on the final results of investment strategy is much more important than the selection of a particular econometric model in order to correctly evaluate the equity risk premium.

Celem pracy jest ocena ryzyka oraz efektywności inwestowania w wybranych sektorach GPW w Warszawie. Za pomocą modeli Sharpe’a i Markowitza, a także wykorzystując wybrane metody analizy portfelowej dla spółek należących do sektorów: surowce, paliwa i energia, przeprowadzono badania empiryczne. Praca składa się z dwóch części. Pierwsza ma charakter metodyczny, druga zawiera ważniejsze wyniki badań i wnioski. Na podstawie przeprowadzonych analiz można stwierdzić, że inwestowanie w ww. sektorach daje wysokie stopy zwrotu, zatem jest atrakcyjne dla inwestora. Niezbędna jest jednak dogłębna analiza danych historycznych w celu wyboru walorów najbardziej bezpiecznych oraz zyskownych.
The aim of the paper is to estimate the investment risk in selected sectors on Warsaw Stock Exchange. Using Sharpe’s, Markowitz’s model and some methods of portfolio analysis investment risk and investment efficiency were examined. In Sharpe’s model the slope of a straight line (beta coefficient) is appointed (using closing stock prices and market index). However, depending on chosen market index the values of the coefficient are different. In the article the values of estimated beta coefficients were examined and compared. The paper consists of two parts: the first is methodological one, the second presents main results and conclusions.

Opis:
In the study, two approaches of rate-of-return estimation are compared. One of them, that predominates in practice and that is called by the authors heterogeneous, refers to a separate rate-of-return estimation for every individual asset, and then to an interpolation of obtained values in order to asses rate of return for any portfolio with priorly given proportions of assets. The heterogeneous approach is based on premises concerning a proper method of rate-of-return estimation for individual assets, and a specific method of interpolating estimates for any portfolio as well. In contrast, the other approach, called homogeneous, refers to uniform treatment of all portfolios without exceptions, which leads to a direct rate-of-return estimation for any portfolio with priorly given proportions of assets. The essence of both approaches and discrepancies between them are illustrated with use of properly chosen examples (arbitrary and empirical). Examples' analysis indicates some advantage of the homogeneous approach over the heterogeneous one.

Decision makers often heave to deal with a programming problem vhere some of the quantities are unknown. They will usually estimate these quantities and solve the problem as it then appears - the "approximate problem". Thus, there is a need to establish conditions which will ensure that the solutions to the approximate problem will come close to the solutions to the true problem in a suitable manner. The paper summarizes such results for multiobjective programming problems. The results ase illustrated by means of the Markowitz model of portfolio optimization. In order to show how probabilistic constraints may be dealt with using this framework, a shortfall constraint is taken into account.
