Informed trading before positive vs. negative earnings surprises

This paper investigates whether institutional investors trade profitably around the announcements of positive or negative earnings surprises. Using Korean data over the period of 2001–2010, we find that information asymmetry is larger before negative earnings surprises (earnings shock) among investors and that the trading volume decreases only before earnings shock announcements due to the severe information asymmetry. We also find that institutions sell their stocks prior to earnings shock announcements whereas individual and foreign investors do not anticipate bad news. Finally, we find that institutional trade imbalance is positively related to the post-announcement abnormal returns of negative events. This study complements and extends prior literature on informed trading around earnings announcements by documenting evidence that domestic institutions exploit their superior information around particularly earnings shock announcements.     

Distribution of institutional ownership and corporate firm performance

We investigate the association between corporate firm performance and the level and stability of institutional ownership within a simultaneous equation model. Our main ownership stability measures include ownership persistence and the time-lengths over which investors hold non-zero shares or maintain their shareholding. We find that there is a positive relationship between firm performance and institutional ownership stability, accounting for the shareholding proportion. This relationship is robust to the employment of ownership turnover measures used in the literature and consistent with the view that stable institutional investors play an effective role in monitoring. When we disaggregate institutional investors into pressure-insensitive and pressure-sensitive categories, we find that stable shareholding of each group has a positive impact on performance, with the first group exerting a larger effect. The channels of the effect include, but are not limited to, decreased information asymmetry and increased incentive-based compensation.     

How disclosure quality affects the level of information asymmetry

We examine two potential mechanisms through which disclosure quality is expected to reduce information asymmetry: (1) altering the trading incentives of informed and uninformed investors so that there is relatively less trading by privately informed investors, and (2) reducing the likelihood that investors discover and trade on private information. Our results indicate that the negative relation between disclosure quality and information asymmetry is primarily caused by the latter mechanism. While information asymmetry is negatively associated with the quality of the annual report and investor relations activities, it is positively associated with quarterly report disclosure quality. Additionally, we hypothesize and find that that the negative association between disclosure quality and information asymmetry is stronger in settings characterized by higher levels of firm-investor asymmetry.     

How does ownership concentration exacerbate information asymmetry among equity investors?

This study investigates the association between ownership concentration and information asymmetry between informed and uninformed investors, and explores several mechanisms that mitigate such a relation. Using a large sample of Korean firms whose ownership structure is highly concentrated, we find that the degree of information asymmetry increases with ownership concentration. We also find that ownership concentration is positively associated with information asymmetry via an increase in the relative amount of informed trading. This effect more than overcomes the unexpected decrease in the frequency of private information events. Furthermore, while neither institutional investors nor internal corporate governance systems help alleviate the negative effects of ownership concentration, analyst following reduces the information asymmetry associated with ownership concentration. Our findings are robust to endogeneity concerns, additional control variables, and an alternative use of empirical proxies.     

信息不确定、坏消息与投资者交易行为

本文以2000年至2010年的A股上市公司违法违规事件为样本,分析该类事件中信息不确定性的影响,以及市场反应中的投资者交易行为。研究发现:上市公司市场价值在事件日呈显著下跌;然而,与直觉有些相悖的是,信息不确定程度与超额累积收益呈显著正相关,这意味着在坏消息到来时,不确定性反而提高了股票的市场价值;最后,通过对各类投资者在此类事件中的净买入情况分析,我们发现不同投资者的交易行为有明显差异。机构投资者在坏消息中采用了反向交易策略,并且知情交易促进机构投资者的买入。     

Institutional herding in international markets

This paper studies herding behavior of institutional investors in international markets. First, we document the existence of wide-spread herding in 41 countries (referred to as “target countries” hereafter) in the sample. We then examine the relation between contemporaneous institutional demand and future returns and find that institutional herding stabilizes prices. Next, we examine the relation between institutional investors’ herding behavior and the level of information asymmetry in the target countries. We measure the degree of information asymmetry in each target country along five dimensions: (1) stock market development, (2) ease of access to information, (3) corporate transparency, (4) investor rights, and (5) macroeconomic factors that relate to the information environment. We find evidence that institutional investors herd more in markets characterized by low levels of information asymmetry (high level of information transparency). This result suggests that institutional investors’ herding behavior is likely driven by correlated signals from fundamental information. Lastly, we show that price adjustment is faster in informationally transparent markets.     

Institutional investors and post-ICO performance: an empirical analysis of investor returns in initial coin offerings (ICOs)

We examine the role of institutional investors in initial coin offerings (ICOs). Taking a financial investor's perspective, we assess the determinants of post-ICO performance via buy-and-hold abnormal returns (BHAR) in a sample of 565 ICO ventures. Conceptually, we argue that institutional investors' superior screening (selection effect) and coaching abilities (treatment effect) enable them to partly overcome the information asymmetry of the ICO context and extract informational rents from their ICO investments. We find that institutional investor backing is indeed associated with higher post-ICO performance. Disentangling selection and treatment effects econometrically, we find that both of these effects explain the positive impact institutional investors have on post-ICO performance. Overall, our results highlight the importance of institutional investors in the ICO context.     

Institutional Investors and Firm Efficiency of Real Estate Investment Trusts

This study investigates the effect of institutional ownership on improving firm efficiency of equity Real Estate Investment Trusts (REITs), using a stochastic frontier approach. Firm inefficiency is estimated by comparing a benchmark Tobin??s Q of a hypothetical value-maximizing firm to the firm??s actual Q. We find that the average inefficiency of equity REITs is around 45.5%, and that institutional ownership can improve the firm??s corporate governance, and hence reduce firm inefficiency. Moreover, we highlight the importance of heterogeneity in institutional investors??certain types of institutional investors such as long-term, active, and top-five institutional investors, and investment advisors are more effective institutional investors in reducing firm inefficiency; whereas hedge funds and pension funds seem to aggravate the problem. In sub-sample analysis, we find that these effective institutional investors can reduce inefficiency more effectively for distressed REITs, and for REITs with high information asymmetry, and with longer term lease contracts. Lastly, we find that the negative impact of institutional ownership (except for long-term institutional investors) on firm inefficiency reduces over time, possibly due to strengthened corporate governance and regulatory environment in the REIT industry.     

Corporate social responsibility and stock split

This study examines whether socially responsible companies are likely to conduct a stock split. We argue that these companies, compared to their counterparts, could use their strong corporate social responsibility (CSR) performance to reduce information asymmetry with shareholders, and therefore, are less likely to rely on stock splits to signal their future growth potentials. We find empirical evidence to support our hypothesis and investigate the reasons for the lower frequency of stock splits among CSR oriented firms. We find that more socially responsible firms experience a smaller increase in trading volume and a greater increase in bid-ask spread following a stock split than less socially responsible firms. Furthermore, our study finds that, when more socially responsible firms decide to conduct a stock split, they attract a greater proportion of institutional investors with long-term investment horizons.

     

Do Financial Markets Care about Corporate Social Responsibility Disclosure? Further Evidence from China

Corporations increasingly define their corporate social responsibility (CSR) activities as a part of their business. However, is this trend beneficial to investors? Based on an event study methodology and a sample of Chinese listed companies, we extend the literature on voluntary disclosure by exploring the role of CSR disclosure in reducing stock market information asymmetry, as proxied by share price volatility and liquidity. Our results show that the share price volatility after CSR disclosure is lower than before CSR disclosure; however, the trend is that it decreases first and then increases for three months following disclosure. Stock liquidity also significantly improves after CSR disclosure; however, it increases first and then decreases. Additionally, by dividing CSR disclosure into economic (hard) disclosure and generic (soft) disclosure, we find that the reduction in information asymmetry is higher for hard disclosure than soft disclosure, suggesting that although CSR disclosure does indeed have an impact on investors’ behaviour in China, an economic‐based disclosure contributes more substantially. Finally, to better understand the characteristics of the Chinese financial market, we also explore the role of marketisation with results that show that the effect in reducing information asymmetry is greater for companies located in a region with a higher degree of marketisation.     

The impact of CSR performance and CSR disclosure readability on investors’ earnings estimates

We investigate how the valence of corporate social responsibility (CSR) performance and the readability of CSR disclosure impact investors’ earnings estimates. Ninety-seven part-time MBA students participate in an experiment, in which we manipulate the valence of CSR performance (positive versus neutral) and the readability of CSR reports (high versus low), while holding financial information constant. Our findings reveal that investors make more positive earnings estimates when CSR performance is positive. The readability level of CSR reports also influences investors’ decision-making process. Moreover, by using an eye-tracking device, we are able to observe investors’ different reading behaviours upon the different levels of readability.     

Information asymmetry,mutual funds and earnings management: Evidence from China

This paper investigates how information asymmetry and mutual fund ownership affect listed companies’ earnings management. We show that (1) reducing information asymmetry improves firms’ earnings management behavior; (2) relative to short-term mutual funds, long-term mutual funds promote earnings quality by adopting a monitoring role; and (3) by dividing firms into high/low information asymmetry groups, we find that the information environment significantly increases the effect of long-term mutual funds on firms’ earnings management. In this paper, we provide new evidence for the role that institutional investors play in a typical emerging capital market. Our results have clear policy implications: to increase earnings quality, it is essential to improve information transparency and develop long-term institutional investors.     

Daily Stock Trading by Investor Type and Information Asymmetry: Evidence from the Korean Market

We examine the influence of trading by heterogeneous investors on information asymmetry in the Korean stock market, which includes domestic and foreign institutional investors and individual investors. In particular, we examine the relationship between the daily trading volume and the level of information asymmetry reflected in the stock price. The results reveal that high-volume daily trading by domestic institutional and individual investors increases the degree of information asymmetry in the short term, but is more evident for individual investors. Foreign institutional investors tend to mitigate the information asymmetry. Finally, our findings are robust to an alternative measure of investor trading.     

资本市场开放与股权资本成本——基于沪港通、深港通的实证研究

本文基于沪港通和深港通研究资本市场开放对中国内地股权资本成本的影响。研究发现,受政策风险和市场环境等因素所限,沪港通在初始阶段并未对沪市公司的股权资本成本产生显著影响,但随着政策进一步完善、市场逐渐稳定和交易不断活跃,其对股权资本成本的降低效果于实施两年后开始显现;深港通建立在沪港通的制度基础和运行经验上,其在开通后显著降低了标的公司的股权资本成本。本文还进一步分析了资本市场开放影响股权资本成本的竞争渠道和信息渠道,发现深港通对股权资本成本的降低作用主要集中在投资者竞争程度较高,或是公开信息质量较高、信息不对称程度较低的股票样本。     

Impact of directors' networks on corporate social responsibility: A cross country study

We investigate the impact of directors' networks on corporate social responsibility (CSR) activities by using an unbalanced panel data of 2023 publicly listed firms from 17 countries during 2003–2018. Drawing on network theory, stakeholder theory, and institutional theory, we find that directors' networks is positively related to their decision of CSR activities. Additionally, we find a positive relation between directors' networks and CSR during financial crises. Our results still hold after a set of sensitivity tests. The findings in our study expand the academic literature related to directors' networks and CSR activities, and assist policymakers and investors in understanding the importance of directors' networks as determining factor of CSR policies.

Underwriter reputation and IPO underpricing: The role of institutional investors in the Chinese growth enterprise market

This paper investigates the effects of underwriter reputation on initial public offering (IPO) underpricing in the Chinese Growth Enterprise Market, in light of the conflicting evidence in the literature on IPO underpricing. Using data during the post global financial crisis period, we find that IPO firms with prestigious underwriters have lower market-adjusted initial returns on average. We further find that prestigious underwriters reduce IPO underpricing by minimizing the time gap between the offering and listing, choosing high-quality firms to underwrite, and reducing information asymmetry between issuers and investors. In the presence of institutional investors, however, we find that more underpricing occurs, as these investors tend to obtain access to IPO shares at a higher price discount via private placements. This new finding suggests that the institutional investors have a role to play in the case of high under-pricing, which partly gets corrected via underwriter reputation.     

Institutional Ownership and the Dynamics of Trading Volume around FFO Announcements

We examine the effect of institutional ownership on abnormal trading volume around the announcement of funds from operations (FFO) by real estate investment trusts (REITs). Our central thesis is that abnormal trading volume is lower for the more informed institutions vis a vis non-sophisticated retail investors/institutions. We find a negative relationship between ownership by pension funds and abnormal trading volume around quarterly FFO announcements. However, ownership by the other types of institutions is unrelated to abnormal trading volume. Consistent with the view that some institutional investors are more informed than individual investors and therefore respond less to end of year announcements, we find that higher ownership by investment advisors is associated with lower levels of trading volume around end of year FFO announcements. Lastly, we find no evidence of institutional sell-offs associated with announcements of less than expected FFO.     

Reactive or proactive? Investor sentiment as a driver of corporate social responsibility

Investors and financial markets have been a neglected stakeholder group in studies on a firm’s motivations to be socially and environmentally responsible. Despite being a strong driving force behind firm value, no study has investigated the influence of market and investor sentiments on CSR behaviour. Using a global sample, we investigate the effects of market and investor sentiments on firm CSR performance. We find negative market and investor sentiments in the prior year motivate firms to improve their CSR performance in the next year. We also find the magnitude of improvement in CSR performance differs not only by country, but by CSR sub-category as well. These findings imply that a firm’s motivation to improve its CSR performance is reactionary, rather than being driven by altruism. Regulators and proponents of CSR should thus seek to persuade investors and financial markets to put pressure on firms to further advance the CSR agenda.     

Determinants of intellectual capital disclosure in prospectuses of initial public offerings

Intellectual capital is recognised as the new economic era’s pivotal factor underlying value creation. Deficient and inconsistent intellectual capital reporting is escalating information asymmetry between informed and uninformed investors. This provides fertile ground for informed investors to extract higher abnormal returns and higher wealth transfers from uninformed investors, particularly during a firm’s initial public offering (IPO). This study investigates the association between intellectual capital disclosure levels in prospectuses of 444 IPOs listing on the Singapore Stock Exchange between 1997 and 2006, and three potential explanatory determinants: (1) ownership retention; (2) proprietary costs; and (3) corporate governance structure. Statistical analysis supports our conjecture of a positive association between intellectual capital disclosure and ownership retention. We also find, consistent with expectations, a negative influence of proprietary costs on the positive intellectual capital disclosure – ownership retention association. However, contrary to predictions, we do not find an IPO’s corporate governance structure significantly influences the negative interaction of proprietary costs on the ownership retention – proprietary cost association. Our findings have implications for various parties such as regulators who may impose unnecessary costs on issuers if they introduce mandatory disclosures whilst lacking an understanding of the factors influencing intellectual capital disclosures.
