Den här studien undersöker hur vinstvarningar påverkar stora och små företag. För att förklara dess påverkan på företagen har den effektiva marknadshypotesen och behavioral finance använts som grund. Avgränsningen har gjorts till Stockholmsbörsen då inga tidigare studier haft fokus på den. Empirin visar att företag i Large Cap påverkas med i snitt -4,63% och företagen i Small Cap med -8,42%. Large Cap visade signifikanta abnorma avkastningar under eventdatumet och dagen efter medan Small Cap endast visade signifikans under eventdatumet. Vid en portföljjämförelse mellan de två listorna ligger resultatet i linje med den effektiva marknadsteorin. Däremot vid detaljerade mappningar av företagens aktier kan anomalier hittas som kan förklaras av olika psykologiska fenomen inom behavioral finance. / This paper studies how profit warnings affect largeand small companies. The efficient market hypothesis and behavioral finance was used in orderto explain the affect of the profit warnings on the companies’ stocks. The boundary wasdetermined to be the Stockholm OMX since no previous studies had been performed in this particular fashion. The data demostrates that companies within Large Cap are affected with an average of -4,63% and the companies in Small Cap with -8,42%. Large Cap showed significantabnormal returns during the event date and the day after while Small Cap only showed significance during the event date. A portfolio comparison between the two lists reveals results that are in line with the efficient market hypothesis. However when using detailed data of thecompanies stocks some anomalies can be found, which can be explained by psychological phenomena within behavioral finance.

We live in an era where internationalization and globalization are two extremely attractive concepts. People aim to create a society where limits and restrictions are erased and a thriving society is a reality. Numerous transformations have occurred in order to realize this and one of the most vital ones is the globalization of the economy. The globalization was made possible through the discovery on the capital market. This market enables people to trade with each other, no matter place or time. Thus, a more efficient solution is offered for rapid and significant transfers such as loans and investment. According to various researchers, the capital market determines, in a way, which company will grow and which will stagnate in development. However, the capital market needs to be efficient in order to offer the services intended. The aim of this dissertation is to explain how efficient the capital market is when incorporating information regarding football player transfers. By examining the empirical findings, it will also be able to establish if assets of the same market value cause different share price fluctuations depending on if they are acquired or sold.

This thesis analyzes devolopment of profitabilty and market structure of banking sector in the Czech Republic, Slovakia, Poland and Hungary. Empirical results are consistent with structure-conduct-performance hypothesis, on the other hand efficiency hypothesis seems to be unlikely. These conclusions are furthermore supported by DEA efficiency analysis. Results of non-structural Panzer-Rosse model suggest that during the period under consideration, market outcome was similar to monopolistic competiton. The results of regression analysis reveal that bank-specific variables, share of banking deposits on GDP, GDP growth and interest rates are the main drivers of banking sector profitability.

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...

This study investigated the relationship between capital structure, performance and replacement of chief executive officer in firms listed on the Nairobi Securities Exchange (NSE). Data was collected from a sample of 37 firms listed on the NSE over a period of 23 years, from 1990 to 2012. The analysis was conducted at three stages. The canonical correlation technique was employed to investigate the bi-directional relationship between capital structure and performance and to select competing indicators of performance and capital structure. Second, the general linear model (GLM) procedure was used to test the effect of performance and ownership structure and to test the effect of capital structure and ownership structure. Lastly, the generalised estimating equation (GEE) was used to assess effects of performance, capital structure and ownership structure on change in CEO. The results revealed that a bidirectional relationship exists between capital structure and debt capital. The indicators found to be useful in examining the relationship between performance and capital structure are asset turnover ratio and total debt to the total asset ratio. The findings support the efficiency hypothesis but not the franchise hypothesis. The results also indicated that firms with a low asset turnover are with a low asset turnover are 3.045 times likely to change CEO compared to firms with a high asset turnover. The results also indicated that firms with high leverage (debt) are he results also indicated that firms with high leverage (debt) are 3.430 times likely to change CEO compared to firms in low leverage, while the firms with medium leverage are are are are 6.491 times likely to change CEO. Therefore managers should not be passive when it comes to choosing between equity and debt capital played a disciplinary role on firms listed on the NSE. / Business Management / DCom (Business Management)
