Are institutional investors colluding with manipulators?

This paper examines the trading behavior of institutional investors in Taiwan before, during, and after a manipulation event and determines whether institutional investors benefit from their trading behavior during the period from the year 2000 to 2020. We find that stocks with a low turnover and small market capitalization are the main targets of price manipulators. In addition, the stock price of manipulated firms increases from the start date of the manipulation event, peaks at the end of the event, then falls after the event. Foreign institutions collude with manipulators to exaggerate stock prices for self-benefit. In contrast, securities dealers counter the trading behavior of manipulators and act as market stabilizers, causing them to suffer losses. Moreover, foreign institutions earn higher returns on stocks of manipulated firms with a low turnover during and soon after manipulation; however, they earn a higher return on stocks of manipulated firms with a high turnover in the long run after manipulation.     

Liquidity provisions by individual investor trading prior to dividend announcements: Evidence from Taiwan

This paper investigates the role of liquidity provisions played by individual investors prior to dividend announcements in Taiwan. We first document a positive relationship between aggregate individual trading before dividend announcements and abnormal stock returns in the one month after the events. We find that this positive relationship varies with liquidity. We then decompose the abnormal returns following the event into information and liquidity provision components. The information component is not significant at all, but the liquidity component is positively significant, which shows that it is individual investors’ provisions of liquidity to institutional investors prior to dividend announcements that drives the positive relationship between pre-event individual trading and post-event returns.     

Does corporate environmental protection increase or decrease shareholder value? The case of environmental investments

This study examines share price effects of environmental investments using data from the Finnish forest industry from 1970 to 1996. The results indicate that the instantaneous market reaction is negative, and that the larger the investment, the larger the fall in prices. However, contrary to the view that corporate actions have a permanent effect on firm value, we observe rapid price recovery after the instantaneous negative reaction. This may support a hypothesis that environmental investments create goodwill for the investing firms and are thus not negative net present value investments. Unexpectedly, we find that the instantaneous negative market reaction was stronger in the most recent sample years. Explanations for this finding relate to the slowness of institutional change within the financial community as well as to the growing share of international investors seeking short‐term holding gains. In conclusion, it appears that not only finance theory but also notions from institutional theory and corporate environmental management literature are needed to explain stock price behaviour in conjunction with environmental investments.

Stock volatility and trading

Both, rational and behavioral models predict that stock and market volatility affect trading by investors. Tax-induced trading hypothesis predicts that investors increase realization of capital losses short term and capital gains only long term as volatility increases. Behavioral models predict that disposition biases of holding on to losers and disposing of winners intensifies with volatility. We document that market and stock volatility influence stock trading. Evidence on trading in response to rise in market volatility supports tax-loss harvesting hypothesis – abnormal trading of losers increases and winners decreases. However, evidence on trading patterns conditional on individual stock volatility is in support of both tax-loss-harvesting and behavioral models: trading in both losing stocks (tax-loss-harvesting hypothesis) and winning stocks (disposition effect hypothesis) increases with rise in stock volatility.     

When Auditors Say ‘No,’ Does the Market Listen?

Previous research on whether the market responds to auditors’ opinions has provided mixed results. We revisit this issue in China, where individual investors who are more likely to neglect value-relevant information dominate the stock market. In addition to going concern opinions (GCOs), China permits modified audit opinions (MAOs) on violations of accounting standards or disclosure rules (GAAP/DISC MAOs), providing an opportunity not available in the literature to enrich the study of audit-opinion pricing. We find that, ceteris paribus, MAO recipients underperform in the future and have a higher incidence of adverse outcomes such as misreporting and stock delisting, and the market reacts negatively to MAOs during the short window around MAO disclosure. Importantly, MAO disclosure is not followed by negative long-term stock returns, suggesting stock price adjustments to MAOs are speedy and unbiased. These findings hold for both GCOs and GAAP/DISC MAOs. Together, our findings support the informativeness of audit opinions and cast doubt on the argument that investors inefficiently price audit opinions due to information-processing bias.     

Leadership change and shareholder value: How markets react to the appointments of women

This study examines whether the appointment of women into senior leadership positions has a more positive effect on share price than the appointment of men into equivalent positions. Our dependent variable is the degree of change in share price following the announcement of men and women into senior leadership positions. Although market reactions to corporate events represent a complex process, we argue that changes in stock price represent a barometer for how investors assess the decision's potential effect on a corporation's short‐ and long‐term economic viability. We find a significant spike in stock price following the announcement of women into top leadership positions. The size and direction of change in stock price, however, is moderated by the gender composition of the industry. © 2011 Wiley Periodicals, Inc.     

Contrarian strategies and investor overreaction under price limits

This study investigates the effects of price limits on investment performance of contrarian trading strategies in Taiwan’s stock market over the period 1997 to 2006. All contrarian strategies in intraday limit-hit stocks lead to superior returns relative to the benchmark index return, and the findings support the overreaction effect. Also, there is evidence of delayed overreaction reflected by price continuations for the overnight period and price reversals for the subsequent trading day. Moreover, investment performance of contrarian strategies is related to firm characteristics where investors tend to overreact more in small-size, high-turnover, and non-high-tech stocks. Finally, price overreaction is strong for up-hit stocks in the aftermath of catastrophic events. If overreaction exists, price-limit regulation designed to cool off investors and reduce price volatility may not be effective.     

The impact of investor structure on stock price crash sensitivity: Evidence from China's stock market

Stock price crash sensitivity refers to the conditional probability of a stock crash when the market collapses. It focuses on individual stocks' sensitivity to the market crash and can affect stock pricing significantly. Although the crash sensitivity of China's stock market is very high as a whole (Weigert, 2016), different individual stocks show varying degrees of crash sensitivity. This paper, adopting the perspective of institutional investors, explores the reasons for the difference in crash sensitivity in China's stock market, and finds that: First, institutional investors' shareholdings is positively related to firms' stock price crash sensitivity. However, after dividing institutional investors into professional (represented by financial institutions) and non-professional institutional investors (represented by general legal persons), we find that only professional institutional investors' shareholdings is negatively related to firms' stock price crash sensitivity. Second, the impact of professional institutional investors on the crash sensitivity is influenced by stock liquidity and media sentiment: when the stock liquidity of listed companies is good or the media sentiment is strong, the negative impact of professional institutional investors on the crash sensitivity is accordingly high. This paper, by highlighting the investor structure, attempts a pioneering exploration of the influencing factors of the difference in stock price crash sensitivity in China. Our empirical results enrich research on stock price crash sensitivity and the heterogeneity of institutional investors. They can also serve to guide regulatory authorities' development of institutional investors and efforts to maintain market stability.     

Disclosure quality,price efficiency,and expected returns

Using a composite disclosure quality measure, we examine the effect of disclosure quality on price delay and the effect of price delay determined by disclosure quality on expected returns in the Taiwan stock market. We find that higher disclosure quality can reduce stock price delay through more investor attention and higher stock liquidity after we control for accounting quality variables and consider the endogeneity issue. Furthermore, we show that disclosure quality reduces expected stock returns through the price efficiency channel associated with both investor attention and stock liquidity. Our results indicate that increasing a firm’s standardized information rating by one standard deviation can reduce its expected stock return by 0.63% annually. Taken together, our evidence suggests that regulatory activities enforced to improve public firms’ disclosure quality in the Taiwan stock market can make the stock market more efficient and therefore lower investors’ required return for stocks.

An Investigation of Stock Price Declines Following Corporate Financing Events: Further Evidence

Prior research documents a large downward drift in stock prices following issuances of debt and equity by US firms. We conduct tests based on both stock price and trading volume to provide evidence on the reasons for this apparent market anomaly. We document evidence of earnings management through accruals prior to external financing and lower operating performance afterward that is associated with the amount of capital raised. The earnings management that precedes external financing and the amount of capital raised are associated with both the post-financing decline in stock price and trading volume around earnings announcements that follow for a period of three years. This evidence is consistent with the proposition that firms raise external capital prior to predictable declines in their operating performance and they release upward biased earnings before these events to manage investor expectations. The failure of many investors to incorporate this information into their trading decisions in a timely manner consistent with limited attention and over-confidence appears to drive stock mispricing. Our evidence does not support the conjecture that the financing anomaly is primarily a statistical artifact or that it is a manifestation of the accrual anomaly.     

Information asymmetry,sentiment interactions,and asset price

We develop an asset pricing model with sentiment interactions between institutional and individual investors under the condition of information asymmetry. Our model considers private information and investor sentiment, two imperfections in securities markets, and integrates them into a theoretical model to investigate the role of the interaction between information asymmetry and investor sentiment in asset pricing. We show that the joint effect of private information and investor sentiment deviate the price of risky assets and efficiently explains anomalies in the stock market. Investor sentiment changes the effect of information on the equilibrium price relative to a world where all investors are completely rational. Private information changes the effect of investor sentiment on the equilibrium price in comparison with a scenario with symmetric market information. In addition, the individual investors’ learning and the disclosure of information both allow private information to be better integrated into the price and simultaneously changes the effect of investor sentiment on the equilibrium price.     

Partners of USEPA Climate Leaders: an Event Study on Stock Performance

This research utilized an event study method to assess how the stocks of publicly traded companies responded before and after announcing their partnership with the United States Environmental Protection Agency (USEPA) Climate Leaders program. Although the stocks exhibited an average non‐significant positive abnormal return of 0.56% on the day of the announcement, the cumulative abnormal returns for the stock prices of the firms for two of the three event windows showed statistically significant negative returns. These results suggest that these firms' public announcements of joining the USEPA Climate Leaders partnership did not have a positive impact on stock performance. While no immediate financial benefit was found in this research, the practices implemented by these firms to reduce their greenhouse gas emissions may still bode well for long‐term corporate earnings and attractiveness to investors.

How cultural dimensions,legal systems,and industry affect environmental reporting? Empirical evidence from an international perspective

Past research has paid little attention to the impact of stakeholder engagement, cultural, legal, and industrial contexts on environmental disclosure. Thus, the aim of this paper is to explore how these three institutional factors affect the reporting of environmental information by companies in different countries. This research draws on institutional theory: normative isomorphism, coercive isomorphism, and mimetic isomorphism. This study uses the generalised method of moments procedure. The findings show that the legal system and certain cultural dimensions such as individualism, uncertainty avoidance, long‐term orientation, and indulgence are determinants of voluntary disclosure of environmental information (individualism and indulgence—negatively; uncertainty avoidance and long‐term orientation—positively), particularly when companies belong to industries with high environmental risk.     

Asymmetric positive feedback trading and stock pricing in China

Defining asymmetry of feedback trading (AFC) as the difference between buying-winners and selling-losers intensities, the paper investigates if AFC impacts stock pricing. We show that buying stocks with low AFC and selling stocks with high AFC makes significant positive returns after controlling traditional pricing factors. The return mainly comes from the long leg and cannot be simply attributed to either mispricing, liquidity, or risk premium. Further study shows that the negative impact of AFC on future stock return is reinforced with an increase in past returns, maximum daily return, relative valuation level, asset growth rate, or operating profit rate. As AFC represents retail trading intensity, the results imply that the inactiveness of retail investors may make price relative underreaction to good news and thus lead to positive expected stock return.     

Does it pay to be green? A disaggregated analysis of U.S. firms with green patents

The objective of this paper is to investigate the relationship between environmental performance and financial performance on a sample of 361 U.S. firms over the 2007–2016 period. We contribute to the literature by considering firms active in sustainable innovations by obtaining green patents. We also contribute to the literature by using disaggregated measures of environmental performance collected from the Bloomberg ESG database, including environmental disclosure score, greenhouse gas emissions, waste emissions and water use. Panel data regressions' results show that environmental transparency positively influences current accounting and stock market performance, but negatively influences the return on capital employed. Furthermore, lower pollution emissions tend to improve the current return on assets, while being harmful for the efficiency of long‐term capital employment at the same time. The empirical results also indicate that the Global Financial Crisis (2007–2010) increased the environmental transparency of firms with green patents but negatively impacted their price to earnings ratio. At the same time, lower waste disposal diminishes stock valuation while the opposite is true with water use. Taken together, our results suggest that environmental transparency and greenhouse gas emissions generally appear to be the most important environmental variables influencing financial performance, with increasing importance attributed to them by the market after the global crisis period.     

Retail investors’ trading and stock market liquidity

The paper investigates the relation between retail investors’ participation in trading and aggregate stock market liquidity. The findings show a positive and significant relation between retail investors’ trading and stock market liquidity. Examination of the determinants of retail investors’ trading reveals that, on average, retail investors with more diversified trading activity tend to trade when liquidity is higher, the frequency of their arrival to the market is not affected by the level of liquidity, and retail investors are willing to trade at a lower liquidity level as sellers than as buyers. Moreover, retail investors’ trading does not create price noise at the aggregate market level. Overall, the evidence suggests that retail investors contribute to market quality.     

The Multijurisdictional Disclosure System and Value of Equity Offerings

The Canada and US multijurisdictional disclosure system (MJDS) implemented in 1991 lowered the indirect barriers for investors and issuers by easing reporting and disclosure requirements for cross‐border issues. This paper examines the impact of the MJDS and related regulatory changes on Canada–US equity market segmentation using a sample of Canadian seasoned equity offerings in the 1991–1998 period. We find that the number of cross‐border issues by Canadian firms increased, and the typical negative stock price reaction that accompanies seasoned equity issues declined over time, supporting increased integration between the two markets after the MJDS. We also document that cross‐border issues experience about 1.4 per cent lower negative stock price reaction compared with domestic issues, consistent with Canada–US market segmentation. We find mixed support for Merton's (1987) investor recognition hypothesis. While Canadian firms cross‐listed in the US experience a less adverse price reaction to their cross‐border offerings compared with their non‐US‐listed peers, there is no significant difference between the two groups in the case of purely domestic issues.     

Stock price reactions to stock dividend announcements: A case from a sluggish economic period

The 2007 financial crisis and the Great Recession that followed resulted in a loss of confidence among investors, and regaining their full trust and confidence has been a challenge for companies. Although economic growth has been volatile throughout the postwar World War II period, recent growth (2008–2015) has been remarkably weaker than in the previous low-growth period (1974–1995). The 2006–2015 period is often characterized by sluggish economic growth. This study investigates stock price reactions to stock dividend announcements, 30 days before and after the announcement dates, of publicly traded companies in the period 2006–2012. We use an event study methodology for 460 events and daily stock price data for companies in the CRSP historical data set. The study shows a significant reaction in stock prices around the event date. On average, stock prices reacted positively to stock dividend announcements. However, compared to previous findings of abnormal returns (5.9%), results from this study show small abnormal returns (about 1.81%) attributable to stock dividend announcements that are cumulative of the announcement day and up to 3-day post-announcement days. Our estimates are even lower than the 2.01% stock price reaction obtained in the 1987–1996 period.     

Does Short Selling Enhance the Allocational Role of Stock Price? Evidence from Hong Kong

We investigate the real effect of short selling on corporate investments and, in particular, examine whether short selling improves managerial learning from stock prices in making investment decisions. We find that short selling improves investment sensitivity to stock price, most likely through a channel that short selling increases stock price informativeness. Using the lifting of uptick rule for index arbitrageurs and market makers as an exogenous shock to short selling intensity, we confirm the causal effect of short selling on managerial learning. Overall, our evidence suggests that short selling enhances the role of stock price in resource allocation.
