Assessment of stock market efficiency and selection of a suitable investment strategy
SCHREIB, Vladimír
The work aims to approach the analysis of the efficiency of the stock markets and to create a suitable investment strategy, the result of which is the maximization of the possible return. The theory of efficient markets is based on the assumption that there are no stocks on the market that would be poorly valued, since all information is available and is immediately reflected in the share price. Based on that assumption, abnormally high profits that would exceed the market average cannot be achieved in the long term. Using statistical tests, the research compares the efficiency and performance of stock markets across stocks and indexes from around the world in the period from 2017 to 2021 and then selects an appropriate investment strategy using a passive, technical and fundamental strategy. The conclusion is that although the markets behave very differently, the overall efficiency could be described as weak. A passive portfolio investment was chosen as a suitable investment strategy.

Efficient market hypothesis in the modern era
Vlček, Šimon ; Krištoufek, Ladislav (advisor) ; Korbel, Václav (referee)
Efficient Market Hypothesis (EMH) has been the central assumption of financial modelling in the previous decades. At its core, it is a statement about the efficient incorporation of available information in the prices of assets, rendering each price a 'true' representation of the asset's intrinsic value. The notion of informationally efficient financial markets has been, since its formulation, entrenched in the very core of our understanding of how asset pricing works, yet, with ever so increasing frequency, when subjected to empirical scrutiny, it fails to prove its explanatory and predictive prowess. New academic strands emerged have emerged as a result, attempting to explain those empirical short-comings, with rather mixed results. The new models and theories often either explain a singular anomaly, rather than pro- viding a generalized and consistent theoretical framework, or are exclusive with the general state of financial markets, which tends to be efficient and rational. This thesis shall explore the relationship of information and financial mar- kets, taking into account developments that have occurred since the inception of the EMH. Subsequently it will present a new theoretical model for asset pric- ing and ipso facto the efficiency of financial markets, based on meta-analysis of information, along...

Information asymmetry in economics
Kolar, Jan
The subject of the article is the concept of information asymmetry, which currently belongs among highly discussed themes in economics. In the article, we deal with the basic concepts, which play an important role in the overall perspective on the given issue. One of them is moral hazard, which is a fundamental consequence of information asymmetry. The market subjects or individual people often misuse their superior informational capabilities for their own use, but at the same time they inadvertently contribute to the inefficiency of the specific market, which can lead to extensive market failure. Other important consequences include so-called adverse selection, which results in the gradual displacement of good products by inferior ones. The occurrence of adverse selection in the specific market then results in pressure to reduce prices. In particular, the article analyses the current state of knowledge in the area of information economics, on the basis of previously published articles. We also deal with the effect of modern technology on the economic mechanism and information asymmetry. One of them is the internet, which plays a key role in the transmission of information. The aim of the article is to perform an analysis of the current state of knowledge in the area of information asymmetry on the basis of relevant published articles, and thus create a comprehensive and compact perspective on the given issue. An important section is the analysis of the possible impact of modern technology on information asymmetry, where own conclusions are drawn on the basis of findings by various authors.
