Vančura, Filip ; Streblov, Pavel (advisor) ; Červinka, Michal (referee)
The objective of the thesis is to investigate the efficiency of pension funds' investment strategy in the Czech Republic and the adequacy of the current level of real estate investments in their portfolios. We employ Markowitz portfolio theory and construct the optimal market investment portfolio. The optimal portfolio is then compared with the portfolio of Czech pension funds and the loss arising from asset class misallocation is estimated. Besides, the comparison of portfolio structures of all current pension funds in the Czech Republic is done with the intention to detect whether they follow significantly different investment strategies or not. The analysis is done on quarterly data over the period 2000 - 2011. In the last chapter of the thesis, other sources of market inefficiency of the Czech pension funds are discussed.

The efficient frontier during the financial crisis.
Kocholová, Soňa ; Pošta, Vít (advisor) ; Makovský, Petr (referee)
Bachelor thesis deals with the basics of portfolio theory and its applications, mathematical and graphical models in the theory of portfolio and, finally, an estimate of the specific efficient frontiers during the financial crisis. The aim of the work is to estimate, graphically illustrate and to compare the efficient frontier for specific states in the course of eight years. These sets of portfolios are composed of two assets and that is one risk and one risk-free asset. A result of this combination is an efficient frontier illustrated in a form of the capital market line and its slope given by so called risk premium. We will focus on the comparison in time for each state individually and at the same time each year separately between the states themselves. Finally, a specific example of portfolios with various share of risk and risk-free assets are compiled lying on the line of an efficient frontier.
