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.
