With few previous data and literature based on the South African banking sector, the key aim of this study was to contribute further results concerning the effect of operational loss events on the reputation of South African banks. The main distinction between this study and previous empirical research is that a small sample of South African banks listed on the JSE, between 2000 and 2014 was used. Insurance companies fell outside the scope of the study. The study primarily focused on identifying reputational risk among Regal Treasury Bank, Saambou Bank, African Bank and Standard Bank. The events announced by these banks occurred between 2000 and 2014. The precise date of the announcement of the operational events was also determined. Stock price data were collected for those banks that had unanticipated operational loss announcements (i.e. the event). Microsoft Excel models applied to the reputational loss as the difference between the operational loss announcement and the loss in the stock returns of the selected banks. The results indicated significant negative abnormal returns on the announcement day for three of the four banks. For one of the banks it was assumed that the operational loss was not significant enough to cause reputational risk. The event methodology similar to previous literature, furthermore examined the behaviour of return volatility after specific operational loss events using the sample of banks. The study further aimed at making two contributions. Firstly, to analyse return volatility after operational loss announcements had been made among South African banks, and secondly, to compare the sample of affected banks with un-affected banks to further identify whether these events spilled over into the banking industry and the market. The volatility of these four banks were compared to three un-affected South African banks. The results found that the operational loss events for Regal Treasury Bank and Saambou Bank had no influence on the unaffected banks. However the operational loss events for African Bank and Standard Bank influenced the sample of unaffected banks and the Bank Index, indicating systemic risk.

In this paper I analyzed the intra-industry competitive and contagion effect during bond defaults in China. The analysis is performed using bond price, since the Chinese stock market is immature and has incredible amount of volatility. The sample includes 15 cases of default across 10 different industries since 2014, and the cumulative effect of the industry portfolio is positive over 11-day event window (competitive effect) with a t-statistic of 6.22. In addition, I found that SOE defaults overall have a significant positive abnormal return on their industry portfolios during 11-day event window with a t-statistic of 4.72, indicating a competitive effect. In contrast, Non-SOE defaults overall have a significant negative abnormal return on their industry portfolios over 3-day window with a t-statistic of -3.36, showing a contagion effect. But this difference could be due to the characteristics of industries as opposed to the nature of SOE. By analyzing the condition and characteristics of each industry, I found that the significance of abnormal return depends on the level of competition of the industry and the level of information available. In terms of contagion and competitive effect, industries showing a contagion effect offer products that are difficult to differentiate, such as cement and water bottle. Industries showing a competitive effect offer products that are highly specialized and rely heavily on technology innovation, such as the special equipment industry and electric equipment industry.

We examine the existence of dividend clienteles in Sweden using a unique dataset containing yearly information on age, gender, income and portfolio composition of about 200 000 Swedish stockholders. The data covers the years between 2005 and 2010. More specifically, we investigate whether investor preferences for dividends differ depending on their age or income. Furthermore, we seek to establish if there are any differences in performance, based on abnormal return, between investors with different dividend yields. We find that age clienteles exist in Sweden; older investors hold stocks with higher dividend yields and invest a larger portion of their portfolio in dividend paying stocks than younger investors. We do not find support for the existence of income clienteles; low-income investors tend to invest in stocks with a higher dividend yield than high-income investors. However, we find that different income groups hold about the same portfolio weight in dividend paying stocks. Overall, we find no significant differences in performance within or between various age or income groups. The main finding of this paper is the identification of age clienteles in Sweden.

I denna uppsats undersöks om den svenska aktiemarknaden överreagerar på historisk information över internränta på samma sätt som De Bondt och Thaler (1985) undersöker den amerikanska aktiemarknaden år 1985, vi replikerar även studien för att undersöka om liknande samband uppvisas för effektiv avkastning. Företag på den svenska aktiemarknaden undersöks och rangordnas efter deras internränta samt deras effektiva avkastning. Baserat på detta delas företagen in i två portföljer, portfölj “låg” och portfölj “hög”. Dessa två portföljer jämförs utifrån Buy and Hold Abnormal Return (BHAR) under tre olika tvåårsperioden. Resultaten visar att den svenska aktiemarknaden överreagerar på historisk information beträffande internränta, vilket skapar ett negativt samband mellan historisk internränta och framtida avkastning som en följd av över- och undervärdering av aktier. Dessa resultat är i linje med de presenterade för den amerikanska aktiemarknaden av De Bondt och Thaler och innebär en möjlighet för investerare på den svenska aktiemarknaden till avvikelseavkastning. För historisk effektiv avkastning hittas dock inget liknande samband med framtida avvikelseavkastning.

Este trabalho visa identificar possíveis vantagens que as empresas obtêm ao contribuir com campanhas políticas. Para isso, foi utilizada uma extensa base de dados com informações de doações a candidatos aos cargos de deputado, senador e presidente nas eleições de 2006 e 2010. As variáveis de interesse analisadas foram o retorno anormal cumulativo à época da divulgação do resultado das eleições e o retorno sobre o patrimônio líquido no ano posterior a cada eleição. Foram estimadas regressões de dados em painel através de mínimos quadrados ordinários, e incluídos efeitos fixos de ano e setor das empresas. Os resultados indicam que não apenas o mercado antecipa benefícios futuros para as empresas que contribuíram com campanhas – o que se reflete em retornos anormais cumulativos positivos à época da eleição – mas também estas empresas apresentam retornos sobre o patrimônio líquido superiores aos daquelas que não participaram do processo político. Além disso, doações a candidatos vencedores geram retorno superior aos de doações a candidatos perdedores; o que vai ao encontro da hipótese de retribuição de favores. De forma similar, contribuições a candidatos filiados à coligação do presidente eleito também apresentaram impacto superior quando comparadas com doações a candidatos da oposição. / This paper aims to identify potential benefits that companies obtain by contributing to political campaigns. We used an extensive database with information on donations to House, Senate and Presidency candidates in the 2006 and 2010 elections. The variables of interest analyzed were the cumulative abnormal return by the time the results of each election became know and the return on equity in the year following the election. Panel regressions were estimated as ordinary least squares (OLS), and fixed effects of year and industry were included. The results indicate that not only the market anticipates future benefits for companies that contributed to campaigns - which is reflected in positive cumulative abnormal returns at the announcement of the election results - but these companies also have higher returns on equity than those that were not involved in the political process. In addition, donations to winning candidates generate higher returns than donations to losing candidates; which supports the return of favors hypothesis. Similarly, contributions to candidates affiliated to the president’s coalition's also had higher impact when compared to donations to the oposition candidates.

This is a study about abnormal characteristics in the stock market and how to successfully use them in personal portfolios. Market anomalies are unexpected excess returns that occur in relation to certain variables. Five commonly known market anomalies (market cap, price-earnings ratio, price-book value, momentum, volatility) are tested to give evidence for their presence. Existing variables are then combined in different portfolios in order to observe whether they generate greater excess returns combined rather than individually. This study will also reveal whether long-term holding is possible and how the anomalies react in bullish and bearish markets.

<p>Huvudsyftet med uppsatsen är att se hur ett företags annonsering om återköp av aktier påverkar dess börskurs i Sverige. Som delsyfte kommer även en undersökning göras om huruvida reaktionen skiljer sig mellan olika branscher samt om Sveriges reaktion skiljer sig från den tidigare forskningen i USA och i Storbritannien.<strong><em> </em></strong></p><p>Undersökningen har genomförts med hjälp av en eventstudie där den abnormala avkastningen beräknas.

<p>This study aims to evaluate the value relevance of Piotroski’s (2000) nine fundamental signals. In order to do this, the signals are tested on the OMX Nordic Exchange Stockholm between the years 2003 and 2009. The hypotheses of the study are whether the signals are value relevant and if the value relevance has changed. To test this, a Chi-square test and a regression are used. The tests show that some signals are value relevant, and that some are not. We also find evidence for a change in the value relevance during the years of the observation. Some explanations to why the value relevance has changed is also discussed.<em></em></p>

<p>The shareholder is supposed to be indifferent if one share costs 100 SEK, or 10 shares cost 10 SEK each. In an efficient market, shares should be valued directly to new expectations as a result of the announcement of the reverse split. We investigate whether abnormal returns incur surrounding reverse split and if owner structure change.</p><p>One reason for the reverse share split is that most companies have plans to imple-ment other company’s specific events in order to survive rather than to change the price range to a more attractive level. We found a negative return in the ex-day at 8,1 per cent. When the ex-day is pure enough from other price driving information should the outcome be a reaction to how the market perceives changes in future divi-dends after the reverse split. In consideration of stock ownership of votes accounted for a reduction of individual owners, and increasing institutional owners, more in companies with low Market to Book. This may suggest that the institutional share-holders have increased their share of votes to increase their power in the companies.</p>
