Tržné prepojenia: Čínsky vplyv na globálne finančné trhy
Horniaková, Veronika ; Stádník, Bohumil (advisor) ; Janda, Karel (referee)
Thesis is looking into the current issue of financial market integrations and linkages between them. In recent year, the topic of China has been emerging to the forefront of academic research, therefore the focus of this paper is dedicated to the integration of Chinese market. The goal is to establish whether there exists an interdependency between Chinese and world stock markets and evaluate and analyse potential influence of China on world indices. The theory standing behind financial integration suggests that individual markets are becoming mutually dependant. Chinese efforts to become a part of global economy gradually become successful which creates room for academic research. This paper focuses on stock indices of two Chinese stock markets in relation to American, English, Japanese, German, Dutch and French indices. Cross-correlation analysis, causal analysis and co-integration analysis are applied to individual indices in order to find the results.

Hedging of a bond portfolio
Kolář, Adam ; Stádník, Bohumil (advisor) ; Kábrt, Tomáš (referee)
The aim of this bachelor thesis is to describe, apply and subsequently analyse the effectiveness of several hedging strategies used when cross-hedging a bond portfolio with futures contracts. The theoretical part of this work is devoted to a general description of characteristics of bonds and futures and, also to basic knowledge of interest rate risk hedging. In the empirical part of this thesis, a bond portfolio is complied, utilising market data, and subsequently it is secured with futures contracts using three different hedging strategies. At the end of the practical part, the effectiveness of each applied strategy is compared. The results of the empirical analysis support, that using the applied strategies when cross-hedging a bond portfolio with futures contracts is in most cases effective.

Sensitivity of Oil Prices to Economic Indicators
Cinert, Vojtěch ; Stádník, Bohumil (advisor) ; Mazáček, David (referee)
The thesis deals with the analysis of the oil market with emphasis on the period from 2010 to May 2017. The aim of the thesis is to test the sensitivity of the oil price to the selected fundamental indicators and trading positions of the traders according to CFTC data. The work, in addition to the theoretical introduction, contains information on key fundamentals such as US oil production, the process of publishing reports on the state of oil stocks in the US, and the process of publishing reports on oil market traders' positions and subsequent data analysis. It confirmed that the price of oil correlates significantly with traders' positions, but the Granger test suggested that the change in the price of oil is causally affecting the position of traders and not vice versa.

Algoritmické obchodování párů
Razumňak, Michal ; Stádník, Bohumil (advisor) ; Fučík, Vojtěch (referee)
Pair trading is a well-known strategy based on statistical arbitrage. This strategy uses a short-term deviation from the mean value of the price ratio of two highly correlated stocks from the same sector as the opportunity to open a position. When ratio returns to its mean value again, the position closes. This strategy has been used for many years and the main outcome of this thesis was to test whether this strategy can be profitable even in current market conditions. For that purpose, data ranging from 2010 to April 2017 on all stocks included in the S&P 500 index were used. It was subsequently found that a pair trading strategy generated 25x higher absolute profit in comparison to random agent. Thus, it can still be considered as a profitable strategy.

Market Making as a trading strategy
Bartík, Jan ; Stádník, Bohumil (advisor) ; Diviš, Martin (referee)
This diploma thesis deals with the market-making strategy's profitability analysis, tested on simulation of central order book. The theoretical part describes how the market maker quotes the price of supply and demand and mathematically proves under which circumstances this strategy is profitable. The practical part introduces a simulation of the central order book. The advantage of simulating the entire order book is that we have information about the number of market participants and quotes at any given time. It also introduces a fictitious market maker quoting the price of supply and demand at any given moment, the price being determined by the price of the previous time step. The order book is simulated in three different settings - random walk, mean-reversion and leptokurtic distribution, and it is shown that the expected profitability of the market-maker strategy is positive in all three cases.

The fast Fourier transform and its applications to European spread option pricing
Bladyko, Daniil ; Stádník, Bohumil (advisor) ; Fleischmann, Luboš (referee)
This master thesis should provide reader with an overview of the European spread options evaluation using the fast Fourier transform numerical method. The first and second part of the thesis deal with the theoretical foundations of Fourier analysis and existing approaches of spread option valuation under two and three-factors frameworks (namely GBM - geometric Brown motion and SV - stochastic volatility). The third part describes extention of Hurd-Zhou (2010) valuation method by tool for call and put spread options pricing in case of negative or zero strikes. Extension will be compared with Monte Carlo simulation results from a variety of perspectives, including computing complexity and implementation requirements. Dempster-Hong model, Hurd-Zhou model and Monte Carlo simulation are implemented and tested in R (programming language).

Multifaktorové oceňovací modely
Karpišová, Iveta ; Fučík, Vojtěch (advisor) ; Stádník, Bohumil (referee)
The theme of this bachelor`s thesis is pricing assets with multifactor fundamental pricing models. We cover the theoretical ground of the single-factor model and three multifactor models, the 3-factor Fama and French model, the 4-factor Carhart model and the 5-factor Fama and French model. The practical part aims to evaluate the explanatory power of the models based on the result of their application on the real financial data, the daily price of the 30 assets of the Dow Jones Industrial Average index. The main achievement is the fact that the best performance on an equally weighted portfolio is that of the 4-factor Carhart model, whereas the market capitalization weighted portfolio`s best estimation is gained with the 5-factor Fama and French model. The difference of the explanatory power of the models is dependent on the way one weights his portfolio and this is proven as statistically important based on the data used in the thesis.

Statistická arbitráž při algoritmickém obchodování amerických dluhopisů
Juhászová, Jana ; Stádník, Bohumil (advisor) ; Janda, Karel (referee)
This thesis deals with statistical arbitrage as a strategy applied in algorithmic trading of US Treasury bonds in the selected timeframe from 1980 until 2017. Our aim is to prove that a specific event on the treasury market, namely reopening of the bonds, constitutes an arbitrage opportunity that enables the investor to systematically yield extraordinary profits on the market. This thesis includes a theoretical introduction to algorithmic trading and statistical arbitrage. Based on this introduction we formulate hypotheses, which are then tested in the application part by constructing an algorithm that simulates a trading strategy on historical data. Comparing three strategies we determined that this strategy is meaningful, or performs better than a random walk and that it is profitable.

Konstrukce výnosové křivky
Antas, Vilém ; Stádník, Bohumil (advisor) ; Teplý, Petr (referee)
The goal of this thesis is to analyze the mathematical apparatus of the most widespread methods used for the yield curves construction. It aims to introduce not only the various of construction models but also to describe the whole process of creation, while discussing the advantages and disadvantage of individual methods. The first chapter focus on the general theory and the use of the term structure of interest rates in practice. The second part deals with the construction process itself and describes the most frequently used methods. The last chapter then shows the real application of selected methods on given data set and the use of the constructed yield curves for interest rate derivative valuation too.
