The Impact of Short-term Interest Rate on Stock Prices in the Czech Republic
Michlian, Štefan ; Princ, Michael (advisor) ; Brechler, Josef (referee)
This thesis focuses on the relationship between short-term interest rate and stock prices. The main idea is that if interest-rate increases, it makes holding stocks less attractive relative to fixed income securities. Therefore, investors change the structure of their portfolios and switch capital from stocks to banks, which results in stock prices decrease. In our thesis, we apply GJR-GARCH-t-M model to study the impact of Czech interest rate (14-day PRIBOR) on the Prague Stock Exchange (the PX index). In contrast to the majority of research on this topic, we have found no impact of the PRIBOR rate on the PX index- neither on its mean nor on its volatility. We attribute the absence of a significant relationship to exceptional composition of the PX index. Furthermore, we have found that the recent crisis has significantly changed the behavior of the Czech stock market.

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...

Impact of Oil Price Shocks on Automobile Stock Prices, An Impulse Response Analysis
Malárik, Lukáš ; Jánský, Ivo (advisor) ; Mikolášek, Jakub (referee)
The goal of this master thesis is to analyze impact of shocks in oil prices to automobile industry stock prices and returns. We decompose oil price shocks on oil supply shocks, aggregate demand shocks and oil-specific demand shocks and assess their individual impacts on these stock prices/returns. This is done using the vector autoregression (VAR) methodology which allows us to compute impulse responses, that is the reaction paths on the individual shocks. In addition to linear VARs we also employ threshold VAR models in order to capture nonlinearities in impulse responses and besides the aggregate automobile stock price index we compute these nonlinear impulse responses also for some selected individual car producers. We think that this analysis have two different uses. First, it can be beneficial to stock market investors. Second, it can be used by policymakers in countries such as Slovakia and the Czech Republic, which are relatively heavily dependent on automotive industry. 1
