Market Response to Investor Sentiment

This paper reconsiders the effect of investor sentiment on stock prices. Our main contribution is that, in addition to the intermediate term return predictability, we also analyze the immediate price reaction to the publication of survey‐based investor sentiment indicators. We find that the sign of the immediate market response is the same as that of the predictability at intermediate time horizons. This is consistent with underreaction to cash flow news or with investor sentiment being related to mispricing. It is inconsistent with the alternative explanations of a rational response to cash flow news or sentiment indicators providing information about future expected returns.     

Investor Sentiment and Stock Returns: Evidence from Turkey

This paper investigates the relation between investor sentiment and stock returns on the Istanbul Stock Exchange, employing vector autoregressive (VAR) analysis and Granger causality tests. The sample period extends from July 1997 to June 2005. In the VAR models, stock portfolio returns and investor sentiment proxies are used as endogenous variables. Two dummy variables accounting for natural and economic crises are used as exogenous variables. The analysis results suggest that, excepting shares of equity issues in aggregate issues, stock portfolio returns seem to affect all investor sentiment proxies, namely closed-end fund discount, mutual fund flows, odd-lot sales-to-purchases ratio, and repo holdings of mutual funds. Investor sentiment does not appear to forecast future stock returns; only the turnover ratio of the stock market seems to have forecasting potential.     

休闲活动与主观幸福感

为了探讨休闲活动与主观幸福感之间的关系。文章采用休闲问卷、正性负性情绪量表和生活满意度量表对460名员工进行了调查。结果表明：（1）性别、是否有孩子等人口学变量影响休闲活动；（2）休闲活动对主观幸福感中的正性情绪和生活满意度有显著的正向预测作用，对负性情绪没有预测作用。     

投资者情绪、异质性与市场非理性反应

许多研究表明,我国证券市场反向策略在短期内获利性较为显著,而动量策略在长期内可以获得超额收益,即中国股市具有短期反应过度和长期反应不足的双重特征。这一现象不仅动摇了有效市场假说的理论基础,而且对现有的行为定价理论模型构成了强有力的挑战。本文尝试从投资者情绪和投资者异质性两个角度对这一异象进行解释。研究发现,在投资者情绪高涨(或低落)阶段,市场更容易反应过度(或反应不足);对于不同类型的投资者,他们的信息反应模式也不尽相同,各自主导了市场在短期内和在长期内的整体表现。这一发现为中国股市在市场非理性反应上所呈现的独有特征提供了很好的阐释。     

上海股票市场空气质量指数的实证研究

空气质量能够通过情绪渠道和信息渠道去影响投资者的决策和投资行为,从而影响股票市场。采用2014年5月14日至2017年2月17日的上证指数、全国PM2.5指数以及百度指数数据,对空气质量如何影响股票市场及其影响力度进行实证分析。结果显示空气质量能够显著地影响股票市场,且季节性紊乱会加剧这一影响力度。此外空气质量对上证工业指数的影响大于上证综指,表明空气质量对特定行业的影响大于整体市场,而信息获取方式又会影响到影响的方向和力度。     

投资者情绪、市场波动与股市泡沫

我国投资者情绪容易受到噪音交易者影响,其他类型交易者可利用噪音交易者的交易策略在博弈中获取超额利润,这为投机性泡沫的产生提供了微观基础。在市场波动机制中,投资者情绪与股价变化存在动态关系,股价泡沫存在内在持续性,引发市场正反馈效应,从而促成投机性泡沫的生成。     

Do Energy Prices Affect U.S. Investor Sentiment?

The current literature has examined the effect of investor sentiment on energy prices, but no study ever has explored the validity of the reverse question. Therefore, this article explore whether energy prices (i.e., crude oil and natural gas prices) affect U.S. investor sentiment, using the methodology of quantile regression. The empirical results document that controlling for a number of U.S. macroeconomic and financial factors, there exists a statistically significant association between oil and natural gas prices and investor sentiment. However, only natural gas prices appear to retain their statistical significance over the majority of quantiles. These findings received robust support under alternative measures of the investor sentiment index.     

Global and Extreme Dependence Between Investor Sentiment and Stock Returns in European Markets

The authors investigate the global and extreme dependence structure between investor sentiment and stock returns in 7 European stock markets (Belgium, France, Germany, Greece, the Netherlands, Portugal, and the UK), over the period 1985–2015. Global dependence refers to the correlation of changes in sentiment and stock returns over the whole range of these 2 variables, and extreme dependence refers to the local correlation of high (i.e. asymptotic) changes in sentiment and high stock returns. Using copula models and a bootstrap procedure, 6 statistical tests are performed for this purpose. Among the results of the tests, the authors highlight those that provide evidence of contemporaneous lower extreme dependence and contemporaneous upper extreme independence between sentiment and returns. As policy implications, these results suggest that financial stability can be promoted if regulators consider the impact of their decisions on investor sentiment. Also, the results seem to support the arguments in favor of short selling ban during turmoil periods. Finally, overall, the results are relevant for both investors and regulators and reinforce the importance of considering investor sentiment to better understand the behavior of financial markets.     

How sensitive are consumer expenditures to retail energy prices?

There is growing evidence that the primary effect of energy price shocks on the U.S. economy involves a reduction in consumer spending. We quantify the direct effect on real consumption of unanticipated changes in discretionary income, shifts in precautionary savings, and changes in the operating cost of energy-using durables. The possibility of asymmetries in the response of real consumption to energy price shocks is also considered. We demonstrate that linear models are consistent with the symmetric behavior of real consumption in 1979 (when energy prices increased sharply) and in 1986 (when they fell sharply). It is shown that historically energy price shocks have been an important factor in explaining U.S. real consumption growth, but by no means the dominant factor.     

国际投资者非理性情绪下的中国国际收支稳定性研究

自2001年以来,经常项目账户和资本与金融项目账户顺差的指数型增长将我国推向了全球国际收支平衡问题的风口浪尖。在国际金融危机频发、跨境流动资金波动剧烈的背景下,我国反常顺差所具有的潜在风险非常值得关注。鉴于此,文章的研究重点在于:(1)采用涉及27个国家股票市场的数据,构建并计算了反映国际投资者情绪变化的风险偏好指数;(2)将国际市场投资者情绪等因素纳入分析框架,实证分析了影响国际资金在我国跨境流动的驱动因素,以辨别跨境资金中的不稳定成分,并给出相应的政策建议。
