Stock Ownership Structure and Related Risk Premium
Rosický, Ondřej ; Baruník, Jozef (advisor) ; Kočenda, Evžen (referee)
Goal of this thesis is to discover the possible risk premium for stocks with respect to their ownership structure. We work with two types of investors, retail and institutional. Those types of investors have different expectations, preferences and behave differently in certain market events. We built the long-short IMR (institutional minus retail) factor as difference in returns of top and bottom portfolios based on proportion of institutional ownership and added this factor to Fama and French Three Factor Model. There is approximately 0.23 % risk premium for stocks with high share of institutional owners. Further we also try to find the possible impact of nominal stock price on ownership structure. With higher nominal price there is higher institutional ownership. On the other hand, this impact is negligible for low and high percentage share of institutional ownership, therefore IMR factor could not be substituted by the nominal stock price. Lastly, we tried to discover what causes the abnormal returns after the execution date. We found out that with increase in retail ownership by 1 p.p., the abnormal returns are higher in one week after stock split execution date by 0.8 p.p. That is in line with earlier discovered risk premium because with the decrease in the portion of institutional ownership...

Vyjádření závislosti mezi rizikovou prémií a ratingovým hodnocením
Závojko, Tomáš
Závojko, T. Dependencies between risk premium and rating. Diploma thesis. Brno: Mendel University in Brno, 2016. Diploma thesis deals with the setting the amount of risk premium for different ratings groups and expression dependencies between risk premium and rating. This issue is connected to the foreign direct investment. In this thesis are used two methods of calculating of the risk premium. In the first method is attributed to the domestic interest rate risk premium, which corresponds to the rating eval-uation of the countries. In the second method, which is used by Damodaran, is used in the context of WACC model CAMP, which reflects the risk premium of countries. This two methods are compared in the conclusion and is answered the thesis, if declining sovereign rating lead to grow in the risk premium and which type of growth it is.

Climate Change Risk Premium, Stock Returns and Volatility Analysis in Relation to ESG Score
Barotov, Timur ; Baruník, Jozef (advisor) ; Vácha, Lukáš (referee)
The purpose of this study is to provide the evidence in regards to how the ESG score integration in the investment strategies affects the stock portfolio performances. The 10 year long panel data on European stocks were used to test how does the corporate ESG score correlate with returns and volatility on corporate stocks and does it (if at all) hold any explanatory power if added to popularly used asset pricing models. Data sample was divided in two based on long and short ESG reporting periods, where on each the analysis was performed separately. Furthermore, both the single sort and double sort analyses were performed to isolate size and ESG effects. Using Fama-MacBeth regression the results seem to suggest that investors are already pricing in the climate related risks as shown by the negative risk premium associated with high ESG firms. Returns and volatility of corporate stocks tend to be lower with higher ESG score, although not uniformly nor very significantly. Comparing Leaders portfolio showed that high (European) ESG scorers underperfomed S&P 500 index both in terms of return and volatility.

An Empirical Analysis of Liquidity Situation and Interbank Rates in the Czech Republic during Global Crisis
Lešanovská, Jitka ; Geršl, Adam (advisor) ; von Terzi, Martina (referee)
This diploma thesis focuses on the development of the interbank market liquidity and interest rates in the Czech interbank market with special focus on the period of global crisis. We analyze determinants of the interbank interest rates and their development with respect to the key monetary policy rate. We explain the significant departure of the interbank interest rates from the key monetary policy rate (impairment of monetary policy transmission) during the global crisis by an increase in risk premia on interbank lending. The source of the risk premia is decomposed into the individual components such as liquidity risk, counterparty risk, foreign influence and other factors. Their contribution to the overall risk premia over time during the global crisis is analyzed. We find that the liquidity risk was the key determinant of tensions in the Czech interbank market in the beginning of the global crisis. However, its influence weakened over time while the role of counterparty risk increased. Keywords: interbank market, liquidity, interest rates, crisis, risk premia, credit risk, liquidity risk, counterparty risk JEL classification: G190, G210

Asset Prices, Network Connectedness, and Risk Premium
Procházková, Vendula ; Baruník, Jozef (advisor) ; Kukačka, Jiří (referee)
This diploma thesis introduces the measures of network connectedness in the context of asset pricing. It proposes an asset pricing model in which the factor of connectedness is included as one of the risk factors together with the three Fama-French factors. The goal of the analysis is to examine whether the con- nectedness represents a signifcant risk factor that should be considered while determining the risk premium of the portfolio in diferent sectors in the market. Using the realized volatilities and returns of 496 assets of SP 500 index over the period 2005 - 2018, that are divided into 11 sectors, we frstly determine the linkages of connectedness between the assets in the same sector. Applying Fama-MacBeth two-step regression model, we explore the signifcance of the connectedness factor for the determination of the risk premium. We argue that the sector overall connectedness represents a signifcant risk in most of the sec- tors and should be therefore taken into account by the investors in all sectors. Moreover, the total directional connectedness that captures the spillover of shocks to one asset from the other assets in the sector, is a signifcant risk fac- tor that should increase the risk premium of the portfolio, especially in sectors such as the fnancial, health care, consumer...

On the Link between Spot and Forward Power Prices: A Comparative Analysis of German and Hungarian Power Market Efficiency
Harnych, Pavel ; Krištoufek, Ladislav (advisor) ; Doležel, Pavel (referee)
This thesis examines the impact of shocks in spot prices on long-term forward contracts in power markets. A unique comparison of efficiency of German and Hungarian power markets is provided. The risk premium on week-ahead forward contract is scrutinized by both data inspection and by unbiased forward rate hypothesis (UFRH) testing. Additionally, the ex-post market's prediction error for this product is explained by main drivers of spot electricity price, which are presented in section devoted to introduction to power markets. Expectedly, Hungarian forwards with longer time-to-delivery are found to react heavily on spot market shocks after controlling for changes in short-run marginal costs of conventional power plants. Such outcome applies both to intra-day and weekly time horizons. However, this evidence was not found for German market. These results point out to immaturity and the presence of inefficiencies in Hungarian power market. However, Hungarian risk premia on week-ahead and day-ahead forward products turn out to be considerably lower than for Germany. This was confirmed by UFRH tests on week-ahead forward contracts, where a significant risk premium was found in Germany as opposed to Hungarian risk premium. This finding is surprising since Hungarian spot prices are more prone to upward...

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.

Vztah mezi rizikovou prémií a ratingovým hodnocením
Závojko, Tomáš
This bachelor thesis deals with the determination of risk premium in foreign direct investment. If investors decide to invest, they need to know how much risk they take. To be a profitable investment, its value should correspond to the premium that investors expect for risk-taking. Through the adjusted net present value of an investment that includes discount rate can be detected risk premium. This work is deals with two methods of calculating the discount rate. In the first method we can determine the risk premium of the real interest rate, in the second method is contained the risk premium in model CAPM. Both approaches use the sovereign rating, whereby I can obtain general results for each rating group. In conclusion I deal with the relation between the risk premium and rating, where I find, if with declining sovereign rating is growing the risk premium and what type of growth it is. Should also be compared these two methods of calculating the discount rate and it will be found, how sovereign rating reflects the risk incurred of investing in the context of foreign direct investment.
