An Extreme Value Approach to Test the Effect of Price Limits on Volatility

Many stock exchanges around the world enforcing daily price limits on the amount asset prices can change to prevent the market from overreacting and to reduce volatility. Price limits are artificial boundaries set by market regulators who restrict price changes of a stock to a pre-specified range during a trading day or a single trading session. The primary aim of price limit rules is to stabilize the markets during panic trading, to moderate vitality by repressing excessive speculation, and to allow stocks to be traded at prices close to their fair value. However, their impact on the market is a somewhat unresolved issue （Harris, 1998）. Using a methodology of comparing volatility based on the extreme value technique, the authors empirically investigate the impact of price limits on the volatility of the Stock Exchange of Thailand. The empirical results support price limits advocates, suggesting that price limits rules moderate stock price volatility.     

Dependencies between price duration,volatility, volume and return on the Warsaw Stock Exchange

The successive changes of asset prices are the most visible manifestation of financial markets dynamics. There exist different views about factors generating these changes, but many researchers and practitioners agree that the most important among them is the impact of information flow. According to the market microstructure theories, it depends mainly on the behavior of informed and uniformed traders. In the paper, we investigate dependencies between the possible proxies of information process： price duration and corresponding to it volume change and return. Our main objective is to answer the question about the most important factor in the process of discovering information by uniformed traders. We apply a set of models for volatility, volume and duration data. Our analysis is performed for selected equities listed on the Warsaw Stock Exchange and uses tick-by-tick data. The obtained results show that the stock liquidity on this leading stock market in Central and Eastern Europe is the most important factor influencing the process of discovering information by uninformed traders.     

The institution efficiency of stock price limits： An experimental analysis on the two stocks market with continuous bid

Price limits in product market have been discarded in classic microeconomics. However, price limits affect the trade behavior of the same agent, since agents in the stock market change their trade status frequently. Due to the controversy on the institution effectiveness of the price limits in stock market, this paper design an experimental market with two stocks with continuous bid, in which we investigate the impact of the price limits on the stock market. The results show that the price limits moderate the price volatility within and between the trades periods, thus can stabilize stock price. In addition, price limits, when measured by traditional approach, restrain the fluidity of the market, reduce the volatility of transaction shares and maintain durative of fluidity. While volatility-based fluidity measurements show that the fluidity is enhanced significantly in stock market with price limits.     

Debt Rating Initiations： Natural Evolution or Opportunistic Behavior？

The authors examine a firm＇s decision to begin issuing debt in public bond markets and find that it is a function of both life cycle influences and opportunistic timing. Defining life cycle factors to encompass both a firm＇s age in years and its underlying characteristics, the authors confirm that bond market participation is generally restricted to large, mature firms. Summary statistics show that finns obtain their initial bond ratings on average 9.5 years after their equity initial public offering （IPO） and 11.8 years after initiating dividend payments. Growth rates, capital expenditures, and cash flow volatility all decline as the firm accesses public debt markets, consistent with entry into the mature phase of its life cycle. With respect to opportunistic timing, it is asked whether entry into public bond markets follows strong performance （or precedes weak performance） at both the firm and market levels. At the firm level, the authors find that the debt IPO occurs following periods of strong operating performance and high excess stock returns. At the market level, entry coincides with favorable interest rates and default spreads. The benefits of careful timing result in firms receiving initial bond ratings that are stronger than what would be predicted; however, there is no evidence of abnormal numbers of downgrades for these firms in subsequent years.     

Medium-term and Long-term Momentum and Contrarian Effects on China during 1994-2004

We examine momentum and contrarian effects in China＇s stock market during 1994-2004 and find that no medium momentum effects exist. Meanwhile, contrarian strategy works effectively over the horizon of 18-36 months. 1-month gap for avoiding bid-ask bounce and lead-lag effect make no considerable change to our empirical results. Transaction costs seem to have no significant impact on contrarian strategies＇ profit.     

Dividend Changes and Future Earnings Performance： Evidence from UK Market

This paper investigates the dividend signaling hypothesis, described here as the relationship between dividend changes and future earnings performance. We find that managers pursue different patterns in UK from that in US when making dividend policy. A positive and significant association between dividend changes and the growth of future earnings is observed in the immediately following year after dividend announced There isn＇t significant link in the longer future. These phenomena are caused by managers＇ near-eyesight in UK market. In addition, an interesting finding is that dividend decreases have larger negative influence on earnings growth than positive impact on earnings prospects of dividend increases. This is consistent with the infrequent occurrence of dividend reduction.     

Comparative Research on the Stock Return Distributional Models

This paper compares the stock return distribution models of mixture normal distribution, mixed diffusion-jump and GARCH models based on the data of Chinese stock market. The Schwarz criterion is also used. We find all these models can capture the features of stock returns partly. EGARCH model is the best fitting to daily return and stable during different period. When the weekly and monthly returns are tested, the differences of the models＇ fitness become unobvious and unstable.     

A Panel Data Analysis of Corporate Attributes and Stock Prices for Indian Manufacturing Sector

Stock prices have always been considered as unpredictable phenomena due to their dynamic patterns. Identifying the forces that contribute to variations of stock prices is probably one of the most researched areas in finance. This study relates stock prices to the stock volatility （measured by beta） and to corporate attributes, i.e., size, liquidity, profits, leverage, and returns. The study is based on manufacturing sector in India, and it is based on a sample of 3,027 manufacturing companies during the periods from 1991-1992 to 2006-2007 collected from the Centre for Monitoring Indian Economy （CMIE） database. The regressions were performed with the dummies for time effect and firm effect separately and then for both effects together. Panel data models have been used to estimate the stock prices equation. The model finds out fixed and random effects between independent and explanatory variables and analyzes them through Hausman test. The paper also studies multicollineairity that may exist amongst the selected variables. The study shows that volatility （represented by Beta）, profit （represented by earnings per share （EPS））, and size （represented by market capitalization （MCAP）） significantly influence the stock prices （at the level of 5%）. Panel data analysis using Hausman test supports the fixed effect model.     

The Analysis of the Governance Effect of Chinese Public Corporation Based on Capital Structure

Under the existed system, the capital structure is the basis of the corporate governance, the structure of the corporate governance is the reflection of the capital structure. The choice of the capital structure decides the level of the corporate governance to a great degree. This paper discusses the governance effect of Chinese public corporation in the view of capital structure. At last, the author suggests that the government should change the state of state-owned stock which takes a great proportion, make the state-owned stocks and corporation stocks enter and circulate in the market, develop investment banks, promote the stockholder＇s rights to circulate and recombine, enhance the supervision and the management of the stock markets, perfect the mechanism of the market＇s operation, set up the mechanism of the way to protect to pay back the debt, perfect the system of bankruptcy and develop the way of bond-financing, offset the drawbacks of the indirect-financing among banks and so on. All of the advice was given to perfect the public company＇s capital structure and improve the efficiency of the corporate governance.     

Long Window Tests of China＇s Stock Market Efficiency in Different Sectors around the Disclosure of Annual Report

10 stock sectors are selected in Shanghai and Shenzhen stock market＇s as samples. By event study, the change of stock＇s cumulative abnormal return rate around the data of annual report disclosure was analyzed among the year 2004-2008. The market reaction pattern of such kind of news was summarized in order to test the efficiency of China＇s stock market and its trend before and after the comprehensive completion of the Share-trading Reform and the imple- mentation of new Accounting Standards. The conclusion is that Chinese stock markets response more accurately to ROE and EPS; its efficiency continued to decline in 2005 and 2006, but there was a gradual increase in 2007 and in 2008; and in general the capital market do not reach the semi-strong efficiency, but the machinery industry and biopharmaceutical industry have done.     

Determinants of market price of stock： A study on bank leasing and insurance companies of Bangladesh

Financial firms make up a substantial fraction of the domestic equity market. A number of studies subsequently used different conceptual and methodological approaches to model equity return of financial services firms. Movement of the stock price as the consequence of the movement of the micro and macroeconomic factors is strongly supported by the literature review. Dhaka Stock Exchange in Bangladesh is inefficient in weak form. Multiple regression analysis is conducted to find out the relationship microeconomic factors with the stock price. In this study found a significant linear relationship among market return and some microeconomic factors such as net asset value per share, dividend percentage, earning per share of bank leasing and insurance companies. Also found non-linear relationship among the variables is insignificant at 95 percent level of significance.

GARCH-Type modeling of stock market returns for the pre-crisis countries

Empirical studies have shown that a large number of financial asset returns exhibit fat tails （leptokurtosis） and are often characterized by volatility clustering and asymmetry. This paper considers the ability of the GARCH-Type （Generalized Autoregressive Conditional Heteroskedasticity） models to capture the stylized features of volatility in national stock market returns for three countries （Portugal, Spain and Greece）. The results of this paper suggest that in the presence of asymmetric responses to innovations in the market, the ARMA （1,1）-GJRGARCH（1,1） skewed Student-t model which accommodates both the skewness and the kurtosis of financial time series is preferred.     

The Changes in World Oil Prices, Monetary Factors, and Foreign Index Toward Composite Index Movement： Indonesian Case for the Period of 2005-2011

Capital market is one of the drivers of the economy through the formation of capital investor excess as well as an indicator of a country＇s economy. Movement of stock price index is often influenced by many factors, derived from the company＇s performance, monetary factor, and changes in world oil prices. This study highlights the problem in world oil prices due to political turmoil in the Middle East. The samples are taken from the Jakarta Composite Stock Price Index （JCI）, oil prices, Indonesian inflation rate, Certificate of Bank Indonesia＇s （CBI） rate, and the reserve assets, during the period from January 2005 to December 2011 （84 months）. Using the data published by the Bank of Indonesia, reports of the Central Bureau of Statistics （Biro Pusat Statistik, BPS）, and other relevant sources, the data analyzed through the Eviews 7.1. The main objective of this study is to examine the effect of oil prices, foreign stock price index, and monetary variables （inflation rate, CBI rate, country＇s foreign reserves, and others） toward the JCI analyzed through the error correction model （ECM）. Hypothesis testing with the F-test for the 95% confidence level indicates that the oil price, exchange rate （Indonesian Rupiah （IDR）/United States Dollar （USD））, CBI rate, foreign exchange reserves, the Dow Jones Index, and the Taiwan stock index, both simultaneously as well as partially have a significant influence on the JCI.     

On FASB Standard Setting:The Role of Funding Structure and Voting Rule

This study develops and tests hypotheses about organizational characteristics of the Financial Accounting Standards Board(FASB)and captures the effects of some recent changes on the operations of the Board in standard setting.I establish a methodology to quantify the complex work of the FASB through factor analysis and condense various proxies into three meaningful performance metrics:thoroughness,timeliness,and consensus.These performance measures are used as dependent variables in a regression analysis to capture how the work of the FASB varies with respect to funding and voting changes.I find evidence that a change in FASB funding from private donations to mandatory accounting support fees is associated with an improvement in Board consensus but no significant change in thoroughness or timeliness.I also find the change in voting rules from supermajority to simple majority is associated with improvements in timeliness but a decline in thoroughness and consensus.Overall,the results suggest that the work of the FASB is multidimensional and that the improvement of one area may come at the cost of another.     

Information content of index inclusions： Evidence from China

This paper examines whether index inclusion has information content and the downward-sloping demand curve hypothesis in China. We investigate the stock price and volume effects when stocks are included in two major stock indexes, the Shanghai Stock Exchange 30 Index （SH30） and the Shenzhen Component 40 Index （SZ40）. Furthermore, we also study the performance changes after index inclusion. We find significant price and volume increases for the stocks selected by the SH30 when the index was created and announced. Thus, the original inclusion may not be an information-free event. For subsequent index inclusions, we observe significant abnormal returns but not abnormal trade volume around the announcement date. However, the stock returns quickly reversed at the post-announcement period. Moreover, the financial performance of index included firms does not improve. The evidence does not support the price pressure hypothesis in China.     

Accounting variables and stock returns： Evidence from Istanbul stock exchange

The fundamental relationship between accounting variables and stock returns is a recurring theme in financial research. 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.     

Private equity investment return analysis based on the earning persistence and trading strategy of new economic enterprise

For the purpose of analyzing the private equity investment return, this paper investigates the extent to which current earnings performance persisting into future depends on the components of earnings, and tries to find out whether stock price reflects the information of earnings. Comparing to accrued components of earnings, cash flow components of earnings has more explanatory ability for abnormal returns and with higher persistence, especially for new economic industry. Eventually we find that investors＇ inability to distinguish correctly among the components of earnings. Constructing a portfolio based on the magnitudes of accrued components of earnings, we can earn 4% to 13% of excess returns for new economic industry and general industry.     

Corporate Governance Viability： Theoretical Exploration

The purpose of this exploratory paper is to try to envision how corporate governance systems and practices are evolving and what eventually determines the forms they take and the functions they perform. Practical implications especially concern different consequences that recent global economic crisis has imposed on regulatory, business, and social aspects of corporate governance. In order to encompass different approaches to this ongoing issue, the author takes into account mainly theoretical contributions that address the issue from the following perspectives： interrelations between product market competition and corporate governance, assessment of capital market pressures on corporate governance; relation between labour market and corporate governance; and actors influencing corporate governance changes in national systems of corporate governance. Since the viability of any corporate governance system and practice, at national and international levels, depends on their ability to respond to both market pressure towards competitiveness and diversified requirements by influential social, political, and economic actors of change, the author suggests that all groups of factors should continue to be in the focus of future researches. On the other hand, as global economic crisis differently affects different countries and businesses, it is of particular importance for those that shape corporate governance policies and practices to be aware of the deep relatedness between corporate governance, on the one hand, and economic, social, and environmental aspects of growth and development, on the other hand.
