This study tests for the market efficiency of the Nairobi Securities Exchange (NSE) after the year 2000 to determine the effect of technological advancements on market efficiency. Data that is used is the NSE 20 share index over the period 2001 to 2015; and the NSE All Share Index (NSE ASI) from its initiation during 2008 to 2015. We cannot accept the Efficient Market Hypothesis (EMH) for the NSE using the serial correlation test, the unit root tests and the runs test. However, we can accept the EMH for the more robust variance ratio test. Overall, the results of the market efficiency are mixed. The most significant finding is that the efficiency of the NSE has increased since the year 2000 which suggests that advancements in technology have contributed to the increase in the market efficiency of the NSE. / Business Management / M.

Simplifications regarding calculations of fatigue life due to vibrational loading is based on weakly stationarity assumptions which is a time independent method. The hypothesis was based on the uncertainty of these assumptions. The aim of this study was to examine whether the analysed data fulfilled the assumptions of weakly stationarity. It was determined that the assumption was not valid for most signals and a comparison of time dependent methods should be performed to evaluate the difference compared with the time independent method. Two time dependent methods were constructed and implemented on the signals based on the results of performed stationarity tests. The result determined that a decrease in fatigue life of an investigated weld might occur for the two time dependent methods compared with the time independent method. The method which was considered to produce the most accurate results was also the most constrained as to the amount of data that fulfilled its requirements. A conclusion was drawn that signals containing more data was necessary to achieve conclusive results of the fatigue life. The hypothesis was proven to be mostly true since most of the analysed signals were found to be piecewise weakly stationary.

The goal of my thesis is to verify the weak form of the efficiency of the exchange market. The paper results from the presumptions for efficient price movements on the financial markets. They are applied to the time series of exchange rates of five currency pairs. After definitions of testing methodology, the given exchange rates series are analysed with the help of correlation and autocorrelation test, runs test and a test based on technical analysis. The conclusion of the thesis anwers the question if the exchange rates movements are suitable with the efficient market hypothesis.

The main objective of this thesis is to analyze selected sectors of the European capital market by means of methods of technical and fundamental analysis. Based on the results obtained for each frame exchanges, industry sectors and the best investment strategy. The first part deals with the theoretical description of securities to capital markets, investment strategies, methods of assessment of the securities in the capital markets, the theory of efficient markets, market testing and evidence of their effectiveness. On the European stock market index, including the German DAX30 randomly selected ninety nine companies with data for the period 2006 {-} the 2011th The work on the basis of a confirmed capital market inefficiencies can be found active investment strategy to achieve above average returns.

The aim of this diploma work was to analyze a selected segment of the stock exchange market using the theory of market efficiency and the methods of technical and fundamental analysis, to form an optimal investment strategy on the basis of the findings. The American stock exchange market was analyzed. Six different segments of the capital market were selected ? gold, oil and gas pipelines, steel and iron, car parts, food and telecommunication services. Each segment was represented by eight companies. The general characteristics of the companies were compared according to their profits, degree of risk, alpha and beta coefficients. Fundamental analysis was used to monitor the correlation between future profits for 2012 and alpha coefficients for the period 2007 ? 2011. The theory was proven ? at low levels of future profits, high levels of alpha coefficients were measured and vice versa - at high levels of future profits, low levels of alpha coefficients were measured. During efficiency tests, runs tests and correlation tests were monitored. During runs tests, the number of turns of a real file was compared with the number of runs of a simulated file; no distinctive variances were identified in the monitored stock titles. Forms of market efficiency were proven during the correlation tests and runs tests. The methods of technical analysis used were sliding averages, RSI indicators and Momentum. Trading on the basis of technical analysis is not completely possible because we did not succeed in finding an existing optimal strategy. If an optimal strategy works out it is regardless of the segment?s characteristics. I recommend a passive strategy with regards to the fundamental analysis.
