We study the relationship between stock price synchronicity and information disclosure of firms listed in the Chinese stock market, using hand-collected data on firms’ official microblogging content in Sina Weibo, a popular microblogging service in China. We find that after controlling for the impact of traditional media, the number of Weibo tweets is related negatively to stock price synchronicity, indicating that stock prices incorporate firm-specific information disclosed in the firm’s official Weibo. Number of microblogging fans can strengthen this negative relationship. Our result is robust to alternative measures of stock price synchronicity, microblogging information disclosure, and to endogeneity issues. JEL Classification: G14, G15

Social responsibility information disclosed by listed companies is an important way to transfer non-financial information to the stock market, which affects the level of stock price synchronicity. In order to explore whether Corporate Social Responsibility (CSR) information is valuable in improving capital market pricing efficiency, this paper conducted empirical research based on a sample of China Shanghai and Shenzhen A-share listed companies in years 2010–2015. The results showed that: (1) Overall, there is a significant positive correlation between CSR information and stock price synchronicity; (2) under different disclosure motives, there is no significant difference in the impact of CSR on stock price synchronicity; (3) Securities analysts and institutional investors can negatively regulate the positive relationship between CSR and stock price synchronicity, while the media will intensify the positive effect of CSR on stock price synchronicity. This research is of great significance in promoting the fulfillment of CSR and improving capital market pricing efficiency.

In China, International Financial Reporting Standards (IFRS) have become mandatory for listed firms in 2007. While earlier research on “voluntary” adopters has provided valuable insights on the impact of IFRS disclosure, these results cannot be generalised in a mandatory setting. We expect effects from mandatory IFRS adoption to be different from those documented for voluntary IFRS adopters since the former group is essentially forced to adopt IFRS. The empirical model, relating to stock price synchronicity with adoption of IFRS, and other firm-specific control variables were analysed using both univariate and multivariate techniques. Different types of panel data estimates were used and compared so as to interpret the results with the best-suited parameters for different data sets for different markets. Studying data covering the period from 2001-2013, the present study examines whether mandatory adoption of IFRS reduces Stock Price Synchronicity for Chinese firms. The empirical results show that IFRS adoption improves information environment by the capitalization of firm-specific information into stock prices, thereby reduces the Stock Price synchronicity. The paper further examines if the information impact was homogeneous across industries. This pattern of decrease in stock price synchronicity after adoption of IFRS is different for different industries taken for analysis. Aerospace & Defense, Automobiles Beverages, Metals & Mining, Retailer& Real Estate Operations have reduced synchronicity but other industries such as Biotech, Electric utilities, Electronic, Leisure products, Renewable energy and Telecom have increased synchronicity. For these industries, the low reliance on market wide information makes reasonable economic sense because they have relatively low demand elasticity. Hence, in demand inelastic industries, future price sensitive factors remain constant and so a changed IFRS accounting regime has little marginal impact. This study provides a different methodological approach by concentrating on Industry wide information effects from the mandatory adoption. These findings have important implications that apply not only to China, but also to other emerging and transitional economies such as India where IFRS is yet to be mandated. Moreover it will help regulators, academicians and practitioners to assess the informational benefit of adopting IFRS.

Purpose The purpose of this paper is to document the impact of stock price synchronicity (SYNCH) on the dividend payout ratio. Design/methodology/approach The authors use data from India for the period between 2000 and 2012 and the panel regression approach to test their arguments. Findings This paper documents that the relationship between synchronicity and dividend payout ratio is positive until a turning point is reached. After that point, synchronicity has a negative impact on dividend payout ratio. The authors argue that firms with low synchronicity have higher information asymmetries. As a result, they have an incentive to develop a reputation as better-governed firms by paying high dividends. However, as synchronicity increases further, information asymmetries go down and as a result incentive to use dividend payouts as a mechanism to reduce information asymmetries goes down. Therefore, positive relationship between synchronicity and dividend payout ratios breaks down at high levels of synchronicity. Originality/value The authors provide evidence regarding the role played by SYNCH – a publicly available measure – on dividend polices adopted by firms within the context of emerging markets.

This research is conducted to investigate the impact of corporate governance on stock price synchronicity in the context of the Vietnamese market. The paper tests four hypotheses proposing the effect of four crucial components of corporate governance including board size, board independence, managerial ownership, and foreign ownership on stock price synchronicity. The study sample includes 247 non-financial listed companies on the Ho Chi Minh Stock Exchange (HOSE) in Vietnam over a period of five years from 2014 to 2018. The fixed effects model is employed to address econometric issues and to improve the accuracy of the regression coefficients. The research results show the positive impact of board size and foreign ownership but the negative impact of managerial ownership on stock price synchronicity. This study confirms the viewpoint that stocks in the market move more together when the firms’ corporate governance gets better. In other words, the research findings suggest that low synchronicity signifies the corporate intransparency and weak information environment and vice versa. From this, the paper provides a new insight to managers on how to improve stock price synchronicity with corporate governance.

This paper explores the impact of securities analysts on China’s capital market efficiency from the perspective of the stock price synchronicity. Empirical results show that increased securities analysts can improve capital market efficiency, but this effect is limited with economical insignificant. We recommend that the Chinese Securities’ Regulatory Authorities need to further the reform of the securities industry consulting system, thus enhance the capital market efficiency of allocation of resources.
