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.     

投资者监督、政府干预与企业价值——基于机构投资者的经验证据

文章通过模型证明大投资者(Blockholders)与个人投资者相比对上市公司实施更多的监督,并且大投资者的监督行为能够增加企业价值;但模型也表明机构投资者是否实施监督及其为企业带来的价值增量取决于监督的成本和收益。文章利用中国资本市场的机构投资者数据,检验了理论模型的四个基本结论。结果表明:机构投资者比个人投资者更积极地监督上市公司,并有助于提高企业价值;政府干预(用上市公司最终控制人为政府代表)减少了机构投资者监督的收益,降低了机构投资者对企业价值所起到的正面作用,削弱了机构投资者监督的积极性。研究结论表明,发展机构投资者有助于改善上市公司的治理水平,提升企业价值;但是政府干预限制了机构投资者的积极公司治理作用。     

An empirical test of individual and institutional trading patterns in Japan, Hong Kong, and Taiwan

We examine the pattern of daily stock returns in Japan, Hong Kong, and Taiwan. Our results support the information-processing hypothesis: Average returns on Monday are lower than on other days of the week, particularly when the previous trading day’s return is negative. Our results also support the positive-feedback-trading hypothesis: Daily returns exhibit positive autocorrelation, particularly when the previous trading day’s return is positive. Further analysis reveals that institutional investors (Japan), individual investors (Taiwan), or both (Hong Kong) can cause these patterns. Our findings are consistent with the relative importance of institutional and individual investors in each of these markets. We thank three anonymous reviewers for helpful comments and suggestions.     

Institutional investors’ ownership stability and their investee firms’ equity mispricing

This study examines the impact of institutional investors' equity ownership stability and their investment horizon to determine the impact on their investee firms' equity mispricing. Mispricing represents the difference between a firm’s market and fundamental values. We treat institutional investors as a heterogenous group, i.e., dedicated, transient, or quasi-indexer as defined by Bushee, 1998, Bushee, 2001 since their categorization determines their trading strategy. Higher institutional ownership, higher stability in institutional investors' equity ownership, and institutional investors classified as long-term are all associated with lower equity mispricing at investee firms.     

Institutional investors' attention to environmental information,trading strategies,and market impacts: Evidence from China

Using a large proprietary database of intraday high‐frequency trading, we investigate the trading strategies of institutional investors in dealing with the negative environmental event disclosure of listed companies and their impact on markets, aiming to reveal the mechanism of the lack of “green efficiency” in China's capital market from the perspective of institutional investors. The results show that institutional investors react to negative environmental events prior to the announcements, indicating premature information leakage in the market; in addition, their trading behaviors mitigate the immediate effect of negative environmental event announcements on stock price. After the event is disclosed, institutional investors engage in short‐term selling and long‐term buy and hold. This trading strategy undermines the irrational selling of individual investors in the event of disclosure, short‐term decline in stock price, and long‐term reversal of market overreaction. In a China context, institutional investors generally take environmental information into consideration. However, they fail to recognize the long‐term value effect of negative environmental events and instead cater to trading strategies towards market volatility.     

The impact of individual investor trading on information asymmetry in the Korean stock market

This paper examines the impact of individual investor trading on information asymmetry in the market. In particular, we examine the relationship between the trading volume by individual investors and the corresponding bid-ask spread in the Korean stock market, where the majority of the trading activity is driven by individual investors and therefore information asymmetry can be evident. We find that high trading activity by individual investors increases the bid-ask spread in a short investment horizon, suggesting that individual investors, as uninformed and unsophisticated traders, amplify the degree of information asymmetry in the market through trading.     

Individual and Institutional Investors’ Response to Earnings Reported by Conservative and Non‐Conservative Firms: Evidence from Chinese Financial Markets

In this study, we document that there are significant differences in individual and institutional investors’ perception and interpretation of information based on accounting conservatism, as reflected by their trading behavior in the Chinese financial market. Our findings show that institutional investors, who are more sophisticated and have better skills, engage in higher purchases of equities of firms that use high accounting conservatism compared to the firms that use low/no accounting conservatism. Institutional investors’ equity purchases are even higher if these firms are associated with higher growth opportunities. On the other hand, individual investors are attracted more by the attention‐grabbing events and are motivated to purchase equities of firms that either do not use accounting conservatism or use low accounting conservatism, and their purchases are even higher when the firms report positive earnings surprises. Additionally, we find that abnormal returns are higher for the firms using high accounting conservatism and have experienced higher purchases by institutional investors.     

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.     

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.     

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.     

Smart money or dumb money? A study on the selection ability of mutual fund investors in China

We examine investors’ mutual fund selection ability in China. Using actively managed equity mutual funds between 2005 and 2011, we find that Chinese investors generally have no mutual fund selection ability, a result contrary to the smart money effect in the United States. We show that mutual funds that receive more new money subsequently underperform significantly. The findings are robust to several risk-adjusted performance measures. The unique data of China provide separate accounts of institutional and individual investors’ new money flowing into and out of mutual funds, allowing us to examine the mutual fund selection ability of institutional and individual investors. We document that institutional investors exhibit a smart money effect, that is, they are able to move new money into (out of) future good (poor) performers. In contrast, individual investors exhibit a dumb money effect. Our results provide useful information for regulators to review their rules, especially for the protection of individual investors regarding mutual fund investing in China. In addition, we show that it is useful to distinguish institutional and individual investors in mutual fund research.     

Accruals quality,information risk,and institutional investors’ trading behavior: Evidence from the Korean stock market

This study analyzes the effect of firm-specific information risk, measured by accruals quality, on the cost of capital using institutional investors’ trading behavior. Institutional investors in firms with lower accruals quality increase their net selling in later years. Furthermore, these investors’ net selling is relevant to the innate and discretionary factors of accruals quality. This relationship is stronger for foreign institutions than for domestic institutions, and it is mostly observed under favorable macroeconomic conditions. We do not observe this relationship for large business groups connected by shares.     

短期内机构投资者行为和股票价格的互作分析

研究短期内机构投资者行为与不同规模公司股价的相互影响.在机构投资者对股价的影响方面,阐释并论证了机构持股比例增量与当日股价的正相关关系,指出机构对大盘股的影响强于对小盘股的影响.机构资金流入(流出)的定性信息本身对股价上升(下降)有额外的促进作用;相对于撤资而言,股价对机构的注资行为更敏感;而对小盘股,该不对称性更加明显.此外,当日收益率和前三天内的机构资金流入存在负相关关系,且该种负关系在大盘股中的表现比在小盘股中更为明显.在股价对机构投资者行为的反馈作用方面,以实证结果阐明了股价上升(下降)的信息本身可对机构行为有缓冲作用,且该作用对小盘股影响大于对大盘股的影响.研究显示,在短期内机构更倾向于动量交易,这在小盘股中尤为明显.三天前收益率对当日机构行为的影响颇为明显,且与一天前的收益率的影响力相当;相对而言,两天前收益率对机构行为的影响不甚明显.     

Influence of institutional investors' participation on flipping activity of Malaysian IPOs

This paper examines the influence of institutional investors’ participation on flipping activity of Malaysian IPOs. Measured as the percentage of trading volume on the first trading day against the total number of shares offered, flipping is the quickest way to gain huge profits from IPOs. However, excessive flipping activity has significant potential to create artificial downward pressure on the price of IPOs. One way to reduce such an adverse effect is by strategically allocating a larger proportion of new shares to institutional investors. This is because institutional investors are normally assumed to be long-term investors. As such, they are less likely to flip their allocated IPOs in the immediate aftermarket. The long-term investment argument is consistent with institutional investors’ preference for a steady income stream in the form of dividends. Drawing upon this argument, the greater participation of institutional investors during an IPO is expected to be an effective strategy to control aggressive flipping activity. The Malaysian IPO market offers an excellent opportunity to examine this hypothesis because data regarding the allocation of new shares to institutional investors can be traced conveniently through a type of IPO referred to as “private placement”. Based upon an examination of 248 IPOs listed on Bursa Malaysia between January 2000 and December 2012, this study finds a negative relationship between institutional investors’ participation and flipping activity. This result lends strong support to the argument concerning the effectiveness of institutional investors’ participation in controlling flipping activity in the Malaysian IPO market.     

机构投资者与公司治理

随着机构投资者的发展壮大,人们越来越关注其对公司治理方面的作用。由于机构投资者巨大的股票持有量,他们存在参与公司治理的愿望。但因为经济往来关系、法律法规规定、信息处理障碍导致机构投资者并不能有效地参与公司治理。     

机构投资者持股与企业创新质量——基于非线性视角的研究

高质量的创新活动能够有效推动经济发展与转型。以2010—2020年A股上市公司为样本探究机构投资者持股与企业创新质量的关系。研究发现，机构投资者持股对于企业创新质量的影响存在区间效应，随着机构投资者持股量超过一定阈值，其对于企业创新质量表现出抑制效应，即二者具有倒U型的非线性关系。压力抵抗型机构投资者是造成非线性关系的重要力量。而市场竞争强度与企业吸收能力则有助于缓解机构过度持股对企业创新质量提升的抑制作用。     

A model of international asset pricing under imperfect commodity arbitrage

This paper examines the effect of imperfect international commodity arbitrage (i.e., violation of the law of one price), modeled as the existence of non-traded goods, on the structure of purchasing power risk, optimal portfolio rules of the risk-averse investors and the equilibrium yield relationship among assets. The major results of the paper include: (i) There are two separate sources of purchasing power risk, i.e., relative price risk and inflation risk; relative price risk is specific to the country in which the investor resides. (ii) In a world of n countries, investors may hold n + 1 hedge portfolios as vehicles to hedge against purchasing power risk; facing different relative prices, investors residing in different countries display divergent portfolio behavior. (iii) In equilibrium, investors are compensated in terms of excess return for bearing not only the systematic world market risk but also the systematic inflation and relative price risks.     

Can Government Policies Induce Earnings Management Behavior? ‐Evidence from Chinese Public Listed Firms

Earnings management behavior is a concern of standard setters, regulators, and investors. This study predicts that government policies can induce earnings management behavior. Based on a sample of 8,765 firm years ranging from 2002 to 2009, this study uses two methods to detect the effect of government policies on managers' earnings management behavior. One is the earnings distribution method developed by Burgstahler and Dichev (1997), and the other is the modified Jones model proposed by DeFond and Jiambalvo (1994). We find that policies issued by the China Securities Regulatory Commission (CSRC) can induce managers of listed firms to engage in earnings management to either avoid negative consequences (e.g., delisting) or to meet requirements (e.g., refinancing). So, although the purpose of government is to protect investors as well as to promote the healthy development of the securities market, its policies are a double‐edged sword: if there is no strict and effective control mechanism, government policies can harm investors and disturb the normal order of the securities market.     

Day trading and stock price volatility

When an investor buys and sells the same stock on the same day, he is said to have made a day trade. Using the trading records of Finnish traders, this paper examines whether day trading is related to volatility of stock prices. I find a strong positive time-series relation between the number of day trades by individual investors and intraday volatility among heavily day traded stocks. This effect is robust after controlling for a previously documented volume–volatility relation. The result suggests that the joint hypothesis of price pressure and volatility induced day trading dominates the liquidity effects of day trading.     

Investor heterogeneity and commonality in stock return and liquidity

This paper examines how the trading activities of different investor types are related to common return and liquidity movements. Using a unique dataset, we decompose the daily return and liquidity of individual stocks into price impact components attributable to trades of institutional investors and retail investors. We then investigate the variation of each component relative to market-wide return and liquidity. We show that institutional trades contribute more than retail trades to liquidity commonality. However, retail trades contribute more strongly to return co-movement. The incremental contribution of retail trades to the co-variability of stock returns is more pronounced for firms with high information asymmetry.
