Special problems of non-stationarity in financial time series
Radič, Pavol ; Zichová, Jitka (advisor) ; Prášková, Zuzana (referee)
The aim of this thesis is a detailed analysis of selected approaches of unit root testing. First chapter deals with the basic knowledge of the theory of stochastic processes. Further, we describe Dickey-Fuller tests, t-tests and likelihood ratio tests for the presence of a unit root and derive their asymptotic properties. Numerical studies include comparison of accuracy of the parameter estimates, estimating quantiles of the presented distributions, their graphical presentation and determination of power of our tests. The acquired theoretical knowledge is applied on real data which were analyzed using software Mathematica and R. Powered by TCPDF (www.tcpdf.org)
Technical analysis based on trade volumes and their effectivity from the point of view of future price movements
Chval, David ; Bašta, Milan (advisor) ; Zichová, Jitka (referee)
This Bachelor Thesis studies methods of technical analysis based on trade volume. The first two chapters are theoretical. They describe financial markets, their functions, properties and methods used in analysis of financial instrument. In the next section is described efficient market hypothesis, forms of efficiency and tests of this hypothesis. The third chapter is analytical. The idea that extreme trading activity predict future increase, or decrease of stock prices is investigated. Here is described methodology, data aquisition, analysis results and comparison with other similar research.
Contemporary measures of financial risk
Leder, Ondřej ; Hurt, Jan (advisor) ; Zichová, Jitka (referee)
The main goal of this work is to talk about some financial risks and to introduce some methods of measuring them. The most important part of this work is the value at risk, its extension in form of conditional value at risk and introduction of some of its possible alternatives, which are expectile and spectral risk measures. For this it is needed to give a theoretical framework from the theory of probability. Its goal is to show the similarity of expectile and quantile, because value at risk is practicaly a quantile. Another goal of this fork is to show some weak properties of VaR and to practically illustrate the possibility of using expectile as an alternative to VaR. Powered by TCPDF (www.tcpdf.org)
