Portfolio optimization for an P2P investor on Zonky
Jonáš, Filip ; Polák, Petr (advisor) ; Máková, Barbora (referee)
This thesis analyzes the Czech peer-to-peer lending platform Zonky. The goal was to find the optimal portfolio for a risk-averse investor investing in Zonky loans. For this purpose, the Modern portfolio theory from Markowitz was used. Based on the provided loan book containing information about loans which Zonky has provided since its foundation we examined the statistical properties of the individual risk categories represented by the interest rate charged. The optimization was done using the Excel Solver tool assuming that the loan categories are uncorrelated as well as considering the correlation we found using the variance- covariance matrix. For both cases, the portfolio minimizing the standard deviation as well as the portfolio which maximizes the Sharpe ratio was found. Generally, both types of portfolios were comprised mainly of loans with lower interest rate. According to our results, it seems that such loans offer better relationship between risk and return compared to categories which are riskier. Also, we showed that the platform's recovery rate has a significant impact on the performance of the loan categories especially of those which are among the riskiest. Furthermore, we demonstrated that the correlation between individual risk categories should not be ignored when a portfolio...

Portfolio diversification
MUSILOVÁ, Jana
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.

Is it worth investing in Czech mutual funds?
Sedlačík, Adam ; Křehlík, Tomáš (advisor) ; Pištora, Vojtěch (referee)
In the Czech Republic many people do not invest. Therefore, we try to find out whether Czech mutual funds offer a good opportunity for investment on the Czech market in comparison with American funds. We use Sharpe ratio, Treynor index, Jensen's alpha and Modern portfolio theory to find this out. We conclude that Czech bond mutual funds are safe place to put your money in even though they provide small but almost certain returns. Czech stock funds perform worse than their American counterparts in terms of Sharpe ratio, Treynor index and Jesen's alpha. Applying modern portfolio theory proved to be beneficial in case of mutual funds in the Czech Republic. Powered by TCPDF (www.tcpdf.org)

Stochastic methods in portfolio management
Vacek, Vladislav ; Radová, Jarmila (advisor) ; Burešová, Jana (referee)
From the beginning of 20th century many studies proved randomness in price evolution of investment instruments. Therefore models respecting this randomness must be used in portfolio management. This thesis' aim is to provide basic theory regarding some of the stochastic methods and show their practical use in real situations.

Hedge Funds as a New Investment Perspective
Kĺučár, Michal ; Brada, Jaroslav (advisor)
Práce se zabývá definováním a popisováním hedgových fondů z pohledu konvenčně a racionálně smýšlejícího portfolio manažera resp. investora, a to zejména nepřímo, tedy porovnáním s rozličným příp. alternativními skupinami aktiv. První část představuje zejména úvod do problematiky hedgových fondů a definice jejich stratégií investování. Další část připravuje ?nástroje? k analytické časti. Jsou to převažně přístupy založené na Moderní teorii portfolia (MPT) a Post-moderní teorii portfolia (PMPT). V samotné analytické časti se pak porovnávají a konfrontují jednotlivé druhy aktiv s hedgovými fondami a jejich konkrétními strategiemi. Při tomto postupu je využito celé spektrum nástrojů definovaných v předchozí části. Dochází tak k překvapivým závěrům a poukázáním na zajímavé skutečnosti a souvislosti v této problematice.
