Background: The reasons why this study is conducted is because of the latest recession in the global economy. The current recession has made a lot of companies more aware of its cost, and in order to fit the new harsher economic climate the companies has to be more cost efficient. In order to do so many companies choose to reduce their amount of employees. When this happens in a recession, most of the layoffs are an effect of reactive causes, such as lower incoming orders, and fewer customers. This leads to a problem for the companies that don’t know how these kinds of layoffs will affect the value of the company’s stock. This leads to a question whether there is a significant pattern between layoffs that are a result of reactive reasons and the number of employees that are being laid off, in percentage of the total number of employees of the companies in question? Purpose: The reason for this study is to find out if there is any correlation between how many employees that is laid off, in percentage of the company’s total employees, and if different percentages have different impact in the valuations of the company’s stock. Approach: This study is made in the form of a modified event study and narrows down to the recession during 2008-01-01 to 2009-10-01, and only involves companies that are on trade on the stock market in Stockholm Sweden. The objects that are involved in this study are from the stock markets large and mid-cap sections. The criteria for companies in this study are that they should have made layoffs for reactive reasons in the time period that we are interested in. The variations in the company’s stock are compared to Stockholm’s stock markets OMX-index. The information needed to conduct this study is gathered from press realises and from financial reports made by the companies. Result and conclusions: The study shows that there is a correlation between how large percentage of the company’s total employees that are laid off and the effect of variations in the stock. The correlation is -0,306 but it is not statistical verified. This result was not in line with our hypotheses that we had concluded from earlier research and theories that are in the study. Earlier research on the American stock market shows a stronger connection between large percentage layoffs and how this makes the stock value to decrease.

Post earnings announcement drift (PEAD) is defined as the drift that occurs in a company’s share priceafter their earnings announcement. A company that reports earnings above (below) the analysts’expectations should, according to previous studies of PEAD, continue to drift upwards (downwards)after the announcement. (Ball &amp; Brown, 1968) The thesis purpose is to investigate if PEAD existed onthe Swedish market between 2006-2010. We test PEAD’s existences through; (i) creating portfolios inwhich companies’ abnormal return (AR) we expect to decline or increase, (ii) doing a multiple regressionanalysis to test if the drift is statistically significant. From the results of our study, we can neither acceptnor reject the hypothesis that PEAD existed on the Swedish market, although the multiple regressionanalysis prove a statistically significant result for companies’ AR that we expect to decline have drifted3,11% in a negative direction compared to our total sample.

The post earnings announcement drift is a market anomaly causing a firms cumulative abnormal returns to drift in the direction of an earnings surprise. By measuring quarterly earnings surprises using two measures. The first based upon a times series prediction and the other based upon on analyst forecast errors. This study finds evidence that the drift ex-ists in Sweden and that investor’s systematically underreacts towards positive earnings sur-prises. Further this study shows that the cumulative average abnormal returns is larger for surprises caused by analyst forecast errors. While previous studies have tried to explain the drift by taking on additional risk or illiquidity in the stocks. This study provides evidence supporting that investors limitations in weighting new information causes an underreaction, hence a drift in the stock prices.

Purpose: The main objective of this study is to research whether an announcement of an acquisition generates positive/negative abnormal short-term return towards the buying company’s shareholders. The secondary purpose is to research whether any differences could be due to selected factors: firm size and industry. Method: The study is quantitative in nature where the research aims at the stock price movement around the announcement of an acquisition. The sample size includes 30 companies between the years 2000-2010. The abnormal return is investigated by an Event Study. Conclusion: Our study shows that the publication gives a positive abnormal return in comparison to the respective sector indexes. The result is statistically significant, so we can conclude that an announcement of an acquisition is a positive investment on average. We also found that our selected factors have a significant impact on price performance. Medium-sized industrial companies show positive abnormal returns while smaller IT companies shows a very low abnormal return and large finance companies fluctuates slightly more than other variables, but the value changes are minimal. We also found that the market does not work effectively because of the strange movements before and after the event date.

The Company often enlarge its scale to maintain its competitive advantage by investing. When company lacks of internal funds, it will raise funds from outside. The purpose of this study is to explore how company chooses financial instruments and influence of the announcement effect on stock price. This study analyzes Taiwan listed company by the the sample period from 1993 to 2005. There are two parts of the thesis. The first is the factor of choosing certain financial instrument. We use logistic regression model, both binary and multinomial, to figure it out. The second is the influence of the announcement effect has on the stock price. We use event study to find whether abnormal return exists. Conclusion: 1. If the company¡¦s size is larger, it will choose debt to raise funds. 2. If R&D expense relative to net sales, debt ratio, the proportion of intangible asset are higher, the company will be tend to raise funds by choosing convertible bond 3. If the stock price is overvalued, the company will choose stock. 4. Taiwan listed company will experience negative stock return whatever it chooses stock, debt, or convertible bond.

The primary purpose of this study is to test the effects of inflation targeting in Turkey in terms of providing stability in the financial system by lowering the volatility in the Turkish stock market. Although there are many factors other than monetary policy which can affect stock market volatility, this study examines whether the volatility due to monetary policy can be reduced by increasing the accuracy of investors&rsquo / expectations about the central bank&rsquo / s future actions. In the first part, a &ldquo / Volatility Analysis&rdquo / is conducted for three sub-periods including the pre- and post-periods of the implementation of inflation targeting in order to see whether the volatility in the Istanbul Stock Exchange changed over time. Second, an &ldquo / Announcement Effect Analysis&rdquo / is carried out by using the central bank&rsquo / s interest rate and inflation rate announcement dates in order to evaluate how investors&rsquo / expectations react to a change in these rates during period from 2002 to 2007. Finally, a &ldquo / Combined Analysis&rdquo / is done in order to examine the relationship between the returns in the Turkish stock market and the surprise caused by the realized interest and inflation rates being different from their expected values. The empirical findings about the level of volatility indicate that there is a decline in volatility of the Istanbul Stock Exchange returns when volatility is compared on a pre- and post-policy period basis. Also, it is found that the announcement effect was present, meaning interest rate announcements generally came as a surprise to stock market participants. However, this announcement effect has a notably decreasing trend from 2002 to 2007 which is another evidence of the inflation targeting regime&rsquo / s success at reducing stock market volatility. Finally, the &ldquo / combined analysis&rdquo / shows that CBT&rsquo / s power to effect stock returns and to direct investors&rsquo / expectations increases from 2002 to 2007.

TSEC and OTC listed companies conduct capital increase by retained earnings and stock dividend distribution numerously and that weakens performance of return on equity (ROE), return on asset (ROA) and earnings per share (EPS) and increases stress on managements. Since Formosa International Hotels Corporation pioneered in reducing capital and returning cash to shareholders, this topic has commonly discussed in capital market. Has a company been unable to utilize cash efficiently, reducing capital followed by returning cash to shareholders is a practical option to elevate financial ratio. This study discusses the effect on stock price subsequent to announcement of reducing capital followed by returning cash to shareholders. This study adopts event study to discuss the effect on stock price after declaring reducing capital and returning cash to shareholders and the sample size covers 27 TSEC and OTC listed companies which conducted capital reduction followed by returning cash to shareholders. The results are as follows: 1.The stock price shows positive effect when a company announces reducing capital followed by returning cash to shareholders for the first time. On the date of announcement and the first date after announcement, the average abnormal returns are generated evidently. Accumulated abnormal returns reach the highest level on the date of announcement and the first two days after announcement. Therefore, announcement effect of reducing capital followed by returning cash to shareholders is effective in short term. 2.Based on regression model analysis, return on asset, ratio of reducing capital and P/E ratio are positively correlated with announcement of reducing capital followed by returning cash to shareholders.

In theory, all relevant information is incorporated in stock prices timely and completely and therefore prices respond related news quickly in efficient financial markets. In today's information age, technological advances provide investors with fast access to a vast number of information resources. One can argue that these advances can help market efficiency due to easy and quick access to relevant information. On the other hand, these technological advances not only facilitate availability of relevant information but also facilitate availability of all types of information--both relevant and irrelevant information signals. In essence, one can argue that there is (over)exposure to information which may come with a cost in the form of distraction and limited attention to relevant information. After considering these previous points, this study sheds more light on investor distraction and its impact on stock prices in two essays. My first essay introduces a new type of investor distraction, which arises from the discrepancy between investors' mood state and the content of the firm news. My second essay shows the importance of culture to explain investors' information processing .Moreover; the findings of my second essay are consistent with an investor distraction effect caused by cultural factors which are assumed as irrelevant factors in investors' information environment. In my first essay titled "Overexposure to Unrelated News and Investor Distraction: Earnings News and Big Sports Games", I use mood-generating events - proxied by big sports games -that contain no information on firm fundamentals but occur concurrently with earnings vi announcements to test the hypothesis that investors' attention shifts away from financial news that is incongruent with investors' mood states, thereby leading to underreaction. I empirically confirm the existence of mood-conflicting distraction. I find stronger post-earnings announcement drift and delayed response ratio, and weaker immediate volume reaction, when the earnings announcing firm's local investors' sports mood is inconsistent with the earnings news' content (good vs. bad). This effect strengthens with firm's proximity to the location of the mood source. In my secon essay titled "Post-Earnings Announcement and Religious Holidays", I show the role of culture, proxied by religion, in financial information processing and the impact of culture on financial outcomes through investor inattention. I examine whether and how the religious holiday calendar affects investors' information processing by investigating price reactions to U.S. firms' earnings announcements that occur during Easter week. I find different patterns for short-term and delayed responses to Easter week earnings surprises. Moreover, there is a stronger immediate (delayed) reaction to good (bad) news, primarily found in less religious, predominantly Protestant areas. The results are consistent with a religion-induced investor distraction effect. The findings also show the role of religious characteristics in firms' information environment and the locality of stock prices.

This dissertation is divided into an introductory chapter and four essays. Chapter one discusses the importance of the study and describes the development and growth of the market as well. The first part (Chapters 2 & 3) examines stock returns behaviour and trading activity around earnings announcements. The second part (Chapters 4 & 5) examines price impact asymmetry and the price effects of block trades in the market microstructure context. Each essay addresses some aspects of market microstructure and stock returns behaviour in order to aid researchers, investors and regulators to understand a market which lacks research coverage. The research provides empirical evidence on issues such as the efficiency of the market, information asymmetry, liquidity and price impact of block trades. In first part of the thesis, event study and regression analysis were used to measure the price reaction around earnings announcements and to examine trading activity, information asymmetry and liquidity. In second part the determinants of the price impact of block trades were examined with regard to trade size, market condition and time of the day effects using transaction data. Liquidity and information asymmetry issues of block trades were also studied in this part.
