Portfolio diversification
This master thesis is focused on portfolio diversification. In the Czech Republic, the majority of the population still deposits their free funds to current accounts, but the yield is not sufficient to cover the devaluation caused by inflation. In addition, investments in securities enable these funds to be better valued (naturally with a higher risk). The aggregate of all investments is called the investment portfolio. Harry Markowitz is the founder of modern portfolio theory. The aim of the thesis is to compile an optimal portfolio from chosen financial assets. The theoretical part of the thesis describes the terms such as the financial market, its nature and function and the basic elements of the investment strategy - profitability, risk and liquidity. On top of that, this part describes problems of portfolio theory with a focus on the Markowitz model of optimization. In total 15 stocks-issuing companies are selected from various industries. These companies are traded both on the Czech and American stock markets. The practical part is focused on creating optimal portfolio of selected financial assets. For different attitudes of the investor to risk and its selected strategy the optimal portfolio according to Markowitz is compiled. The weights of individual securities are determined as well as the yield and risk of the portfolios created and an effective boundary is demarcated.
Optimal portfolios
Vacek, Lukáš ; Hurt, Jan (advisor) ; Večeř, Jan (referee)
In this diploma thesis, selected techniques for construction of optimal portfo- lios are presented. Risk measures and other criteria (Markowitz approach, Value at risk, Conditional value at risk, Mean absolute deviation, Spectral risk measure and Kelly criterion) are defined in the first part. We derived analytical solution for some cases of optimization problems, in some other cases there exists numeri- cal solution only however. Advantages and disadvantages, theoretical properties and practical aspects of software implementation in Wolfram Mathematica are also mentioned. Simulation methods suitable for portfolio optimization are brie- fly presented with their motivation in the second part. Multivariate distributions: normal, t-distribution and skewed t-distribution are presented in the third part with connection to optimization of portfolio with assumption of multivariate dis- tribution of financial losses. Optimization methods are illustrated on real data in the fourth part of this thesis. Analytical methods are compared with numerical ones. 1
Šikmost v teorii optimalizace a eficience portfolia
Mikulík, Petra ; Branda, Martin (advisor) ; Lachout, Petr (referee)
In this thesis we study models, which search for an optimal portfolio from a set of stocks. On the contrary to the classical approach focusing only on expected return and variance, we examine models where an additional crite- rion of skewness is included. Furthermore we formulate a model for measuring performance of a portfolio defined as the distance from the Pareto efficient frontier. In numerical experiments we apply the models on historical prices and stock data from the electronic stock market NASDAQ. We analyze the stock data from companies listed in the index NASDAQ-100. We conclude by comparing of optimal portfolios created using different models among each other, with trivial single-stock portfolios and the with NASDAQ-100 index itself.
Portfolio Optimization
Šilarová, Hana ; Karlíková, Jana (referee) ; Novotná, Veronika (advisor)
This master’s thesis deals with problematics of portfolio theory, which helps to create optimal portfolios for the selected investment company. Portfolios consist of shares, which are traded on New York Stock Exchange and which include a historical value at least for two years. There are two ways of creating portfolios. The first way is the portfolio with minimal risk and no required return and the second way is the portfolio with minimal risk and required return. In this thesis are used mathematical methods, which include a linear algebra, an optimization and a statistics.
Technical Analysis
Kubíková, Lenka ; Doubravský, Karel (referee) ; Novotná, Veronika (advisor)
The bachelor's thesis deals with use of technical analysis to create the optimal portfolio of shares. There is primarily used the Capital Asset Pricing Model CAPM. In the first part of thesis there is stated the theoretical background which describes basic information about shares, capital market, technical analysis and CAPM model. The second part of thesis describes individual companies whose shares were chosen for analysis, and it focuses on the detection of buying and selling signals using moving averages. The last part of thesis applies of formation of optimal portfolio and description of application which attends to individual calculations.
Technical Analysis
Loub, Matěj ; Michlovský, Zbyněk (referee) ; Novotná, Veronika (advisor)
The main goal of the thesis "Technical analysis" is to analyze the issue of technical analysis itself, more specifically the CAMP model, which deals with optimizing the portfolio, then design a program to calculate it (generate the required results). This analysis corresponds to the structure of the thesis, while in the beginning of the work are mentioned an important theoretical basis. There is described the financial system, financial and capital markets in connection to the Burza cenných papírů Praha, a.s. and other major capital markets. In addition, I discuss the methodology of technical analysis, CAMP model and the source code and the description of Visual Basic. Then I use this methodology in practice and focus on the goal of the work. Finally I analyze the options, benefits as well as weaknesses of the CAMP model and my program in the Czech capital market conditions.
Optimální portfolio
Menčík, Tomáš ; Musílek, Petr (advisor)
Tato práce si dává za úkol stanovit optimální týdenní portfolio složené z burzovních indexů s přihlédnutím k měnovému riziku a zpracovává data vývoje jednotlivých indexů i směnných kurzů od roku 1999. Optimální portfolio jsem zkoumal z hlediska investora v amerických dolarech, eurech a českých korunách. Na základě analýzy výsledků jsou stanoveny faktory, které rozhodujícím způsobem ovlivňují složení portfolia.
