We suggest that the distortion of the positive risk–return relation in the ICAPM is a consequence of trading by informed investors to exploit mispricing. We hypothesize and demonstrate that a non-positive (strongly positive) risk–return relation following positive (negative) market returns is attributed to short-selling (purchasing) of overpriced (underpriced) stocks along with optimistic (pessimistic) expectations conditional on good (bad) market news. We verify this asymmetry in the risk–return relation through the indirect risk–return relation conditional on good (bad) market news. We also find that the attenuation (reinforcement) of the positive risk–return relation is more profound in high- (low-) sentiment periods. 相似文献

This article examines how investor sentiment affects positive feedback trading behavior. By analyzing the daily closing total return of CSI 300 index and its individual returns of stocks, we find that relatively high or low sentiment induces active positive feedback trading. With a specific indicator of sentiment, we explain the microstructure setting of the relationship between positive feedback trading and sentiment. We adopt the classical feedback model from Sentana and Wadhwani (1992) to measure positive feedback trading behavior. By adding sentiment factor to the model, we successfully explain how sentiment influences the behavior of both feedback traders and rational investors. The empirical findings suggest that positive feedback traders are more likely to trade when the prices of most securities move forward together. When the sentiment of feedback traders is at an intermediate level, the feedback trading behavior is insignificant. 相似文献

This study examines how information broadcasting through television (TV) media influences stock market activities. Consistent with the effect of TV information to attract investor attention, we find that increased information flow through TV is significantly associated with greater trading volume and larger price change. For information type, hard news from business-oriented programmes and earnings-related news strongly contributes to the attention effect, while the effect of soft news is weaker. Bid–ask spread widens for more TV information flows, suggesting that new information arrival in the market expands information asymmetry. Finally, the impact of TV is more influential for stocks with more individual shareholders than those with institutional shareholders. 相似文献

ARE COOPERATIVES MORE PRODUCTIVE THAN INVESTOR‐OWNED FIRMS? CROSS‐INDUSTRY EVIDENCE FROM PORTUGAL 下载免费PDF全文
We analyse empirically whether cooperatives and investor‐owned firms differ in terms of productive efficiency. Using rich Portuguese panel data covering a wide range of industries, we apply two different empirical approaches to estimate potential differences in productive efficiency. The results from our benchmark random‐effects model show that cooperatives are significantly less productive, on average, than investor‐owned firms, both at the aggregate level and for most of the industries considered. However, the results derived from a System‐GMM approach, which is our preferred empirical strategy, are much less conclusive, and we cannot conclude that cooperatives are generally less efficient that investor‐owned firms. With either approach, though, we find no evidence that cooperatives are more productive than investor‐owned firms in any industry. 相似文献

Based on legitimacy theory and resource dependence theory, using 111 listed companies among China’s typically high pollution-emitting listed corporations, research into the effects of environmental disclosure on environmental innovation is undertaken. From the perspective of stakeholders, we analyse the moderating effects of different proportions of institutional investor holdings and types of enterprises on the relationship between environmental disclosure and environmental innovation. The results indicate that corporate environmental disclosure has a positive role in promoting environmental innovation; the proportion of institutional investor holdings has a positive moderating effect between environmental disclosure and environmental innovation. However, there is no significant difference between state-owned enterprises and private enterprises in terms of the effect of the environmental disclosure on environmental innovation, which possibly arises because both types of enterprises make full use of their own advantages to instigate environmental innovation through environmental disclosure. The conclusions may help enterprise decision-makers implementing environmental innovation and government policy makers formulating scientific policies to promote the clean production in enterprises. 相似文献

股权再融资往往意味着企业存在大量的融资需求,而实践中普遍存在的股权再融资后立即现金分红的现象有悖于募集资金的优序使用原则。基于此,本文从管理层自利视角出发,在对企业股权再融资后现金分红的行为偏好检验的基础上,进一步选取管理层薪酬增长率和企业股权质押活动作为管理层自利程度的代理变量,探索企业股权再融资后现金分红倾向的边界条件,为该行为背后的代理动机提供证明。基于2007~2017年所有A股上市公司样本,研究发现,企业的确存在股权再融资后立即现金分红的行为倾向;而较低的管理层薪酬增长率和企业股权质押活动会加剧企业股权融资对现金分红的促进作用。进一步研究发现,企业股权再融资活动会给现金分红带来消极的市场反应。上述研究结果表明,管理层自利是股权再融资的重要推动因素,而这一行为会给企业利益造成损害。 相似文献

We describe a model that predicts an asymmetric impact of disclosure on investor uncertainty. We show that good news tends to resolve more uncertainty than bad news, and that uncertainty can be revised upwards if the investors' prior belief is sufficiently strong and the signal is sufficiently bad. This result is in contrast to classical disclosure models, where new information always resolves uncertainty and the change in uncertainty depends only on the relative precision of the news. Using option-implied volatility as a proxy for uncertainty, we find strong support for our predictions. We also show that our results are robust to competing explanations, notably to the leverage effect and volatility feedback, as well as to the jump risk induced in anticipation of the earnings announcements. 相似文献

Using a sample of countries that require timely disclosures of insider trades, I investigate the effect of country‐level institutions that promote transparency on the extent to which aggregate insider trades predict market returns. I find that financial information transparency mitigates the predictive content of aggregate insider trades when markets are more likely to deviate from fundamentals (i.e., during market fads), and when there is greater co‐movement in stock prices. In contrast, there is some evidence that governance and investor protection mitigate the association between aggregate insider trades and future earnings surprises. Hence, holding constant the timely disclosures of insider trades, other capital market institutions play complementary roles in mitigating the informational frictions that give rise to the predictive content of aggregate insider trades. 相似文献

This paper examines the role of media coverage and investor attention on the outcomes of seasoned equity offerings (SEOs). I use an archive of Thomson Reuters news articles to proxy for firm visibility and investor attention. I find that the volumes of news articles prior to the offerings are positively associated with the offer price discounts of SEOs. Furthermore, the volumes of news articles are negatively associated with the cumulative abnormal returns three days around the SEOs. I conclude that the costs of equity increase with media coverage prior to SEOs. Overall, the evidence is consistent with the hypothesis that media coverage affects investors' information processing in SEOs. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd. 相似文献
