Mergers and acquisitions are one of the most researched topics in the financial literature and many research has been done. This thesis aims to analyse the impact of mergers and acquisitions on firms’ performance for the acquired firms and uses the difference-in-differences  (DID) estimation method with variation in treatment timing to achieve the objective. The dataused in this thesis are collected from database of Institute for Mergers, Acquisitions and Alliances (IMAA) for 25 companies that merged between 2005 and 2019 and from the database of Indonesia Stock Exchange for 25 firms that did not undertake the mergers and acquisitions in the same period. The findings of this study indicate that there are statistically not significant effects on Return on Assets (ROA) and Return on Equity (ROE). This suggests that the mergers and acquisitions do not affect the company's financial performance in terms of profitability.

This paper firstly constructed an order-driven market probability model of informed trading to analyze the correlation between informed trade and return of assets and the trade-price effect. Secondly, using the probability model of informed trading, we constructed a probability model of arbitrage trading in order-driven call market, which could analyze the stabilization fund and the arbitrage trade, to investigate whether the government¡¦s interference measures were necessary and whether the intervened timepoints conformed to the set-up spirit of the stabilization fund¡Xto intervene while falling and not to while rising. Finally, we set up a ratio empirical model of informed trading which could analyze the intraday trade scale of each trade section of informed traders and uninformed traders, to analyze the change of intraday trade scale of each type of investors while trade frequency changed to explore the factors of market performance. The main results are as follows respectively: Regarding the correlation analysis of informed trading and return of assets and trade-price effect, we found that (1) in the short-term (intraday, day) there was no relationship between probability of informed trading and return of assets, whereas in the mid-term probability of informed trading was correlated with return of assets although the influence impact was not as high as prior researches (Hasbrouck (1991a, b), Glosten and Harris (1988)) expected. (2) The intraday probability of informed trading of good news days was obviously higher than that of bad news days, which indicated that unbalanced buy-sell informed trade phenomenon existed in the market. Regarding the investigation of whether the intervened timepoints of stabilization fund conformed to the set-up spirit of the stabilization fund¡Xto intervene while falling and not to while rising, the main results are: (1) the individual stocks intervened by the stabilization fund had slightly smaller volatility, slightly worse efficiency, better returns and significantly larger liquidity. (2) There was no significant difference in the probability of arbitrage trading between the targets intervened by the stabilization fund and the other companies, nor in the performance (including volatility, efficiency, liquidity and return) between both. (3) The stabilization fund and arbitragers tended to conduct transactions in the opening period, which corresponds with the proposition of Schwartz (1988). (4) We also found that compared with other arbitrage trade, the trade of the stabilization fund was more correlated with the price up-down of the market, but not with that of individual stocks. In the analysis of the intraday trade scale change of each type of investors while trade frequency changed, the main findings are: (1) the slowdown of trade frequency caused smaller intraday trade ratio and worse performance in the opening, but it increased the intraday trade ratio and performance of the closing period, which was especially significant in the high-liquidity companies. (2) The increase of trade frequency could raise the liquidity of the high-liquidity and middle-liquidity companies. As to the low-liquidity companies, although the increase of trade frequency increased the liquidity, it raised their volatility and decreased their price finding speed. The main contributions of this paper¡¦s models are indicated as follows. Regarding a probability model of informed trade: first, it improves the prior ones by bringing the order-driven call market model; second, the addition of informed traders¡¦ possibility to use limit order in the model set-up better corresponds to the real market; third, the model can calculate the probability of informed trading of intraday trade section and thus can analyze the intraday and intraweek behavior or phenomenon of informed traders and the market; fourth, the model estimates the probability of informed trading using trade data, not order data, and thus avoids the probability of informed trade estimation error caused by order trade risk; fifth, the model calculates the probability of informed trade of individual stock after separating good and bad news and thus can analyze buy-sell informed trade behavior. Regarding the probability model of arbitrage trading, it provides a method to analyze whether self-stabilization mechanism-arbitrage trade exists in the market to investigate on the necessity of the stabilization fund and its intraday trade behavior. Finally, regarding the ratio empirical model of informed trading, since this paper calculated the section informed and uninformed trade ratio by simulating uninformed traders¡¦ intraday trade strategy and by extracting the ratio of the trade volume variation of intraday trade section explained by uninformed traders¡¦ intraday behavior variation using regression analysis, it can avoid the deficiency that every trade volume was regarded as from a single trader in the prior order empirical model of informed trading.

This paper has studied the relationship between free cash flow & debt with profitability of the Nordic Nasdaq large cap for the period of 2012-1017. Population of the study consists of 223 Nordic companies listed in Nasdaq. From this population a sample of 100 companies from different sectors have been chosen by random sampling, but the sample does not include financial institutions because the way these kinds of institutions are financing differ from companies in other sectors. Data has been collected from Eikon program which provides financial information about the listed companies around the world based on the company's audited financial statements. validity and reliability of the data have been checked to make sure the data are not wrong. In this study, free cash flow, debt to equity ratio & debt ratio are considered as independent variables and profitability of the firm has been considered as dependent variable. In addition, diversity of the companies based on the countries they are established in is considered as dummy variable. Profitability of the firms have been measured by return on asset. The research philosophy is positivism and the research approach is deductive. Based on a quantitative research in which secondary data has been analyzed by running the Pearson correlation analysis and regression analysis. Result of the study revealed that; free cash flow has a positive effect on profitability of the Nordic Nasdaq large cap. In addition, the result of study showed that; debt ratio has negative effect on profitability of the targeted firms. But, the result showed that; the debt to equity ratio does not affect profitability of the firms. The result of running dummy variable revealed that; companies in Finland have 2,3 % lower return on assets compared with the companies located in Denmark. Also, the companies established in Sweden have a 2,3 % lower return on assets compared with Denmark.

It is widely held that CEOs are central to the successful financial performance of companies. Yet, little attention has been given to the correlation between CEO tenure and financial performance of companies specifically. The purpose of this study was to determine whether CEO tenure has an impact on financial performance of companies in South Africa. The financial performance variables for the study were ROA and ROE. The performance of 30 JSE listed companies from three industries, namely, mining, retail and real estate, between 1995 to 2007 was examined. This gave a total of 62 data observations across the selected three tenure categories: short tenure (one to three years); medium tenure (four to five years); and long tenure (six or more years). The results showed that the average tenure for South African CEOs was four years; this was slightly lower than the findings of previous studies conducted in the USA. Medium and long tenure showed better financial performance for ROA than short tenure, while there was no statistically significant finding for ROE. Therefore from an ROA point of view, as tenure increases so does financial performance, until a certain point at which it is anticipated that lengthy tenure will lead to a decline in financial performance. / Dissertation (MBA)--University of Pretoria, 2010. / Gordon Institute of Business Science (GIBS) / unrestricted

This study examines whether the relationship between Corporate Social Responsibility (CSR) and Financial Performance (FP) is dependent on industry belonging. Our accounting-based measurement of FP (Return On Assets) displayed an overall negative correlation with ESG scores, while our market based measurement of FP (Tobin Q) displayed an overall insignificant relationship. We separated the studied firms into the industries Basic Materials, Consumer Cyclicals, Consumer non-Cyclicals, Energy, Financials, Healthcare, Industrials, Real estate, Technology, and Utilities. When separating the studied firms into their respective industries we found that both our accounting-based and market-based measurements of FP was significantly correlated with CSR in 7/10 industries and 3/10 industries respectively. The industries different CSR and FP relationships suggests that firms in different industries have different implications of their CSR practices, and that more extensive industry considerations are necessary to further understand the relationship between CSR and FP.

This study examined the relationship between return on equity (ROE) and return on assets (ROA), the business sector, and long-term performance of new firms 5 years after the initial public offer (IPO) date. IPOs have a high rate of delisting from stock exchanges, and understanding possible predictors of long-term performance will benefit business owners and investors. The purpose of this study was to determine if ROE and ROA are predictors of long-term performance of IPOs on U.S. stock exchanges. The research question examined whether there is a statically significant relationship between the ROE, ROA, business sector, and market capitalization of IPOs. This study followed a correlational design to analyze the research question and its hypotheses. Both shareholder theory and financial ratio models constituted the theoretical framework for this study; public databases provided all the historical financial data on publicly traded companies. The population for this study included all firms that pursued an IPO within the United States stock exchanges from January 2007 through December 2009. Using Spearman correlations, the results suggested no significant relationship between ROE and any business sector with market capitalization of IPOs. However, there was a significant correlation with ROA and market capitalization for these IPOs. The implications for positive social change in this study are new insights for leaders concerning the survivability and monetary gain for new firms entering the public market and the new firm's ability as a result of this gain to provide new jobs thereby improving the economy.

Thesis (M.COM. (Accounting)) -- University of Limpopo, 2022 / The corporate sustainability performance (CSP) journey is coupled with many complex issues which have subsequently eliminated the boundary between legal and discretionary social practices. In South African JSE SRI listed organisations, sustainability performance programmes are regarded as tools for redressing socioeconomic disparities. However, the influence of sustainability performance on organisations‟ financial performance becomes a vital notion in contemporary sustainable development debates as evidenced by extensive inconclusive literature that has its long roots in the research field. The aim of the study is to examine how corporate sustainability performance influences organisations‟ financial performance which is return on assets (ROA). Through content analysis, secondary data were extracted from annual integrated reports of 175 purposively sampled South African organisations registered on the Johannesburg Stock Exchange (JSE SRI Index) for the years 2009-2019. The study employs cross-sectional time series feasible generalised least regression (FGLS) to test the correlation between the dimensions of corporate sustainability performance and return on assets as a proxy for organisational financial performance. The study results confirm that employees‟ health and safety sustainability performance programmes have a significant and positive impact on return on assets, whereas CSP programmes in community social activities have a positive and significant influence on return on assets. An insignificant relationship exists between Eco-investments (socially responsible investments) and return on assets (ROA). The study concluded that there is a significant association between CSP and ROA. The findings further confirm that control variables (leverage ratio, current ratio, total assets turnover, operating profit margin and price earnings ratio) have an effect on the correlation between CSP and ROA. The results have potential implications for corporate sustainability performance policy makers in South Africa, and contribute to corporate sustainability performance/organisations‟ financial performance debate. The study further stresses that continuous review of CSP policies is imperative to ensure that sustainable business practices are achieved.

The foundation stone of this thesis is to perform a financial analysis of Czech non-financial companies for the years from 2007 to 2009 in order to evaluate development of the basic groups of financial analysis ratios before and after the outbreak of the financial crisis. Based on this analysis, I analyze the changes of the selected ratios in relation with the macroeconomic development. This is carried out by means of the description in words and for some significant changes using correlation analysis with GDP. The analysis results in the findings that the changes of ratios of return on assets and return on equity were negative in the analyzed period and for each year the factors of these changes are tracked using the pyramidal decomposition. In the statistical part of my thesis I partially succeeded in proving linear correlation between return on assets and GDP and a lower confidence level linear correlation between personnel cost to revenues ratio and GDP. Also, there were some correlations between individual ratios found to be significant.
