隐性杠杆约束、流动性风险和投资者情绪

本文以2003—2019年间开放式主动管理型的股票型和偏股型基金为样本,以持仓占比为权重估算基金投组中A股的总市场风险暴露,检验结果表明,该序列上升反映了基金面临的隐性杠杆约束收紧,刻画了市场的弱流动性。内在逻辑在于,流动性收紧时,投资者难以通过融资直接增加杠杆,更倾向于重仓持有高市场风险头寸的股票而间接实现杠杆。本文发现隐性杠杆约束所刻画的风险在股票或基金收益截面上的无条件定价基本失效,而条件定价则依赖于低市场情绪与弱流动性。分解基金持股的敞口,进一步发现,因中小盘基金在流动性收紧时具有更强的流动性偏好,其持股的市场风险头寸能够更敏锐地捕捉到弱流动性风险。     

Investor Pessimism and the German Stock Market: Exploring Google Search Queries

We analyze the relationship of retail investor sentiment and the German stock market by introducing four distinct investor pessimism indices (IPIs) based on selected aggregate Google search queries. We assess the predictive power of weekly changes in sentiment captured by the IPIs for contemporaneous and future DAX returns, volatility and trading volume. The indices are found to have individually varying, but overall remarkably high explanatory power. An increase in retail investor pessimism is accompanied by decreasing contemporaneous market returns and an increase in volatility and trading volume. Future returns tend to increase while future volatility and trading volume decrease. The outcome is in line with the conjecture of correction effects. Overall, the results are well in line with modern investor sentiment theory.     

Terrorism activities and long-term annual management forecasts

We study the effects of terrorist attacks on firms’ long-term annual management earnings forecasts bias. We find that the managers of firms located closer to the epicenters of attacks are more likely to issue optimistic long-term annual earnings forecasts relative to the managers of a control group of unaffected firms. The exposure effect is stronger for more severe terrorist events, and firms with more uncertain fundamentals and less geographic diversification. In addition, we document that managers’ forecast optimism intensifies for firms with stronger negative stock market reaction to the terrorist event, for CEOs with higher ability and for companies that are more likely to issue equity or engage in acquisitions following the terrorist event. Overall, our results are consistent with the idea that long-term annual earnings forecasts are used by managers to counterbalance the short-term pessimistic response to terrorist attacks.     

"谨慎投资者规则"与我国基金管理人注意义务的法律完善

美国信托法中的“谨慎投资音规则”是在历经法定投资表和谨慎人规则两个阶段的演进中吸收了现代投资组合理论而形成的。“谨慎投资者规则”作为受托人的一项法定投资原则，不仅比较契舍当今证券投资的实际需要，而且也很好地防范了基金管理人对投资权力的滥用，目前已成为越采越多国家规范基金管理人注意义务的主要依据。我们很有必要对之加以吸收和借鉴，以使我国基金管理人注意义务的内容更为精细化。     

投资者参与和证券投资基金风格业绩的评估

基金风格的形成是投资者参与并选择的结果。基金风格的差异体现出不同基金的设立是为了吸引特定的投资者群体。因此,评价基金业绩就必须从基金风格的供给与投资者风险管理的需求两个方面结合来进行。本文提出投资者参与和选择行为分析的视角,以投资者的风险管理需求的异质性为基础,从投资者身处的位置和衡量标准的不同所产生的异质性从而要求具有的不同目标收益率出发,通过构造连接风格分析与下侧风险指标的风险规避系数来研究基金的风格和投资者的风险管理需求,提出了一个新的基金业绩评估框架。     

王国维:"一代有一代之文学"说的集大成者

“一代有一代之文学”说是一个在世代累积基础上建构的学术命题。这一命题植根于中国传统的文变时序说和文体通变论，并由于王国雏的理论贡献而基本定型．成为中国文学史研究中最重要的学术命题，深刻地影响了20世纪文学史研究的格局与走向。     

略谈代表(执行)董事及其对第三人的责任

现代公司的权力由股东转移到董事会手中 ,而实际行使权力的主要是代表 (执行 )董事。其对公司有一定的控制力 ,就应当承担相应的义务。在代表 (执行 )董事造成公司损害同时也使第三人遭受损害时 ,要对第三人承担损害赔偿责任。我国公司法应该借鉴英美法系的做法 ,以完善我国的公司制度。     

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.     

Wealth effect and investor sentiment

This paper investigated the relationship between the U.S. stock and housing markets as well as their influence on the wealth effect of consumption and found that the stock market sentiment index can explain changes in the wealth effect. The empirical results indicate that these two markets exert a wealth effect on consumption. The estimation results of the Markov-switching model indicate two states: a state in which the stock market influences its coexistence with the housing market and a state in which the housing and stock markets are unrelated. Public optimism regarding stock market investments affects the probability of transitioning between these states.     

Information and Investor Behavior Surrounding Earnings Announcements

The goal of this paper is to analyze the impact of annual earnings announcements on the market through the order flow data in addition to the usual transaction data. In this respect, examining order flow data can potentially reveal valuable information that is not available from transaction data. In fact, the data allow us to test hypotheses about asymmetric information and investor behavior and to test if the behavior varies with investor sophistication. In addition, the paper tries to identify the determinants of the impact on a firm's value using assumptions about investor behavior.
