Thus, comparable accounting information is clearly important, and this study plans to confirm the level of comparability of net income and equity of companies in the financial sector （in Brazil, ＂Finance and Others＂）, listed in the stock exchange, futures, and commodities （BM＆F Bovespal）, issued according to Brazilian Generally Accepted Accounting Principles （BR GAAP） and the IFRS. This study is descriptive, using a quantitative approach. Data were collected from secondary sources, more specifically, from the explanatory notes in the financial statements of the companies listed in the financial sector of the BM＆F Bovespa in the fiscal year of 2010. The results showed a reasonable level of comparability, with 68% of the companies presenting materially comparable information for net income and 72% of them for equity. However, decisions made based on data issued following the two different standards may have suffered the influence of asymmetric information; in other words, the comparability of information did not seem to satisfy those companies during the studied period of time. The main limitations of this study were data collection and selection for the development of the research because of： （1） inconsistence in net income and equity reconciliation criteria in the companies investigated; and （2） lack of uniformity in designating the adjustments that affect net income and equity in the conversion of the BR GAAP standard into the IFRS.展开更多

The study has conducted a univariate analysis of the Tobin＇s Q and the market-to-book ratio for the period before and after the cross-listing by using paired tests. Non-cross-listed firms are then included in multivariate regressions by using pooled Time Series Cross Section （TSCS） and Panel Corrected Standard Error （PCSE） regressions for a period of 13 years to find out if there is a difference in the valuations between cross-listed firms and non-cross-listed firms. The study＇s results indicate that the Tobin＇s Q of cross-listed-firms increases two years prior to cross-listing and that it continues to increase two years after cross-listing. The market-to-book ratios also show an increase two years prior to cross-listing and up to one year after cross-listing, then decrease in the second year after cross-listing. When non-cross-listed firms are included in the analysis, results indicate that cross-listed firms are valued higher than non-cross-listed firms. When data are portioned for positive earnings per share （EPS） and dividends, results indicate that valuation is the highest when EPS is positive. Since segmentation theories cannot be ruled out, the study＇s findings are more in support of the growth opportunity hypothesis.展开更多

One of the major purposes of accounting is to help investors provide reliable, comparable and accurate information. If accounting data are informative about fundamental values and changes in values, they should be correlated with stock price changes. This study provides theory and evidence showing how accounting variables explain stock returns and examines the relationship between the stock returns and accounting variables of listed non financial companies in ISE-100 Indice for 2006-2008 period by using panel data methodology. Empirical analysis consists of 192 observations of 64 companies in years 2006-2008 to examine the effects of inventory, accounts receivable, gross margin, operating expense, return on assets, cash flow, leverage, liquidity, price/earnings, return on equity on stock returns. The results of the study confirm that the predicted roles of fundamental factors and stock returns are significantly related to gross margin, cash flow, leverage and equity variables. The model explains about 13.35 % of the variation of annual stock returns with the leverage variable with most of the significant power.展开更多

We argue that effective disclosure of RPTs can eliminate or at least reduce expropriation phenomena by letting corporate outsiders assess the fairness of the transactions and identify the underlying conflicts of interest. We consider a sample of large RPTs carried out by listed corporations in Italy, a country that has been affected by significant corporate scandals in recent years. In particular, we analyse the content of several compulsory informative documents, required by CONSOB （the Italian Securities and Exchange Commission）, concerning large RPTs. The focus of our content analysis is on the ＂warnings＂ sections of these documents that should convey clear and comprehensive information on potential risks and conflicts of interest. Our empirical results show that, while the ＂warnings＂ sections of the studied documents generally contain all the information required by existing rules, the depth of the information provided is often unlikely to be sufficient to communicate the implications of the RPTs. Thus, readers may not find the disclosed information adequate to evaluate the fairness of the transactions. Moreover, visual representations are rarely used in the informative documents. The use of such representations could allow companies to convey the structures and features of complex RPTs in a simpler and more direct way.展开更多

The paper gives emphasis to the domain of technical analysis. In the broader sense the technical analysis enables the dynamics of the expected future values of the shares estimation. This can be performed on the basis of the data on historical trends of the revenues, profits and other indicators from the balance sheet, but also on the basis of historical data on changes in the values of the shares. Companies generally belong to the different sectors that have different presumptions of development resulting from the global market trends, technology and other characteristic. Processing of historical data values of the outstanding shares of the Zagreb Stock Exchange （ZSE） is origination of this research. Investors are interested to know the estimation of future returns for the stocks as well as the size of the risk associated with the expected returns. Research task in this paper is finding the optimal portfolio at the ZSE based on the concept of dominant portfolio by Markowitz approach. The portfolio is created by solving non-linear programming problem using the common software tools. The results of obtained optimal portfolios contain relevant conclusions about the specifics of the shares as well as the characteristics of the industrial sectors but also provide a further knowledge about diverse sectors treatment at the stock exchange in a multi-year period.展开更多

After stationarity is verified by ADF （Augmented Dickey-Fuller） test, the power spectrum of the data exhibits a power law decay as a whole characterized by 1/f^β processes with possible long range correlations. Subsequently, by using the method of detrended fluctuation analysis （DFA） of the general volatility in the stock markets, we find that the long-range correlations are occurred among the return series and the crossover phenomena exhibit in the results obviously.Further, Shanghai stock market shows long-range correlations in short time scale and shows short-range correlations in long time scale. Whereas, for Japan stock market, the data behaves oppositely absolutely. Last, we compare the varying of scale exponent in large volatility between two stock markets. All results obtained may indicate the possibility of characteristic of multifractal scaling behavior of the financial markets.展开更多
