Dispersion in news sentiment and corporate bond returns

We construct a news sentiment index at the firm level by using textual analysis of news articles and find that dispersion in news sentiment is a significant predictor of corporate bond returns. Bonds of firms with high dispersion in news sentiment have a highly significant average return of 7.38 percent. A portfolio that longs bonds with high dispersion in news sentiments and shorts bonds with low dispersion earns an average biweekly return of 8.53 percent. This finding is in line with an argument that dispersion in news sentiment is a proxy for future cash flow uncertainty.     

Stock market volatility, excess returns, and the role of investor sentiment

Using the Investors' Intelligence sentiment index, we employ a generalized autoregressive conditional heteroscedasticity-in-mean specification to test the impact of noise trader risk on both the formation of conditional volatility and expected return as suggested by De Long et al. [Journal of Political Economy 98 (1990) 703]. Our empirical results show that sentiment is a systematic risk that is priced. Excess returns are contemporaneously positively correlated with shifts in sentiment. Moreover, the magnitude of bullish (bearish) changes in sentiment leads to downward (upward) revisions in volatility and higher (lower) future excess returns.     

Twitter investor sentiment and corporate earnings announcements

We examine the impact of firm-specific investor sentiment (FSIS) on stock returns for negative and positive earnings surprises. Using a measure constructed from firm-specific tweets, we find that FSIS has a greater impact on stock returns for negative relative to positive earnings surprises. We further show that the impact of FSIS is greater for firms whose valuation is uncertain and difficult to arbitrage. Moreover, we provide evidence of return reversals over post-announcement periods. Our results highlight the importance of FSIS around earnings announcements.     

IPO first‐day returns: Skewness preference,investor sentiment and uncertainty underlying factors

In this paper, we investigate the initial public offering (IPO) first-day returns. Our focus is to examine the irrational component of the agent behavior towards IPO lotteries. Based on 234 French IPOs performed between 2002 and 2012, we find that IPOs with high initial returns have higher idiosyncratic skewness, turnover and momentum. This finding provides empirical evidence for investors' preference for stocks with lottery-like features and investor sentiment. In addition, we show that the skewness preference and the investor sentiment effect are stronger during periods of favorable market conditions. Our results are robust to the integration of uncertainty underlying factors.     

News sentiment and the investor fear gauge

This note examines the relationship between aggregate news sentiment and changes in the implied volatility index (VIX). A significant negative contemporaneous relationship between changes in VIX and news sentiment is discovered. The relationship is asymmetric whereby changes in VIX are larger following the release of negative news items.     

Sensitivity to investor sentiment and stock performance of open market share repurchases

This paper finds that stocks of repurchasers with high sensitivity to investor sentiment are more likely to be mispriced. Thus, such repurchases are followed by superior post-buyback stock performance. This abnormal return associated with sensitivity to sentiment cannot be explained by other undervaluation factors: book-to-market or prior return effects. My results are robust with factor model analysis and controls for contamination effects. I conclude that this sentiment-driven undervaluation may result from the difficulty to value and/or limits to arbitrage rather than investor overreaction.     

The impact of conventional and unconventional monetary policy on investor sentiment

This paper examines the relationship between monetary policy and investor sentiment across conventional and unconventional monetary policy regimes. During conventional times, we find that a surprise decrease in the fed funds rate leads to a large increase in investor sentiment. Similarly, when the fed funds rate is at its zero lower bound, research results indicate that expansionary unconventional monetary policy shocks also have a large and positive impact on investor mood. Together, our findings highlight the importance of both conventional and unconventional monetary policy in the determination of investor sentiment.     

Capital regulation and bank risk‐taking – new global evidence

This study investigates the link between capital regulation and bank risk‐taking. Using a sample of over 1,800 banks in 135 countries, I find that the relationship between capital regulation and bank risk‐taking (measured by z‐score) is an inverse ‘U’ shape. That is, as capital ratios increase, a bank will take less risk initially, then more risk. These results are robust to numerous additional tests, including estimation methods. I also find that more stringent regulations mitigate the effect of higher capital on lowering bank risk‐taking. Increased capital requirements, even when risk‐based, induce risk‐taking at higher levels, irrespective of whether banks are well‐ or under‐capitalised.     

The impact of investor sentiment on crude oil market risks: evidence from the wavelet approach

Investor sentiment has become an important factor affecting oil price volatility and extreme risk. Therefore, we utilise a VaR-GARCH model to detect the extreme risk of the crude oil market during 2007–2017, and then explore the causality between investor sentiment and extreme risk in the crude oil market, and their lead-lag and co-movement relationships in the time-frequency domain. The empirical results show that: firstly, investor sentiment leads downside risk but lags the upside risk in the crude oil market; secondly, in the time domain, there is a co-movement between investor sentiment and extreme risk in the crude oil market, in particular, investor sentiment may Granger cause extreme risk in the crude oil market at the 1% significance level but not vice versa; thirdly, in the frequency domain, weak coherence can be found in high-frequency bands but increases in low-frequency bands during the whole sample period, which indicates that the impact of investor sentiment on extreme risk in the crude oil market will last for a long time, although the affected period tends to decrease.     

Returns,volatility and investor sentiment: Evidence from European stock markets

In this study, we show that patterns in returns behave as if investors, influenced by their level of optimism, selected stocks according to their volatility. Our goal is to confirm the contribution of behavioral finance while showing that investor sentiment can be profitably used by practitioners. We incorporate volatility in the relationship between investor sentiment and future returns, this is the main originality of our approach. Our methodology consists in comparing returns, volatility and higher-order moments of portfolios managed with investor sentiment against those obtained either with passive (buy and hold) portfolio management or with a minimum variance portfolio. Portfolios managed with investor sentiment have better returns and involve less risk under certain conditions.     

Investor sentiment and economic forces

Economic theory suggests that pervasive factors should be priced in the cross-section of stock returns. However, our evidence shows that portfolios with higher risk exposure do not earn higher returns. More importantly, our evidence shows a striking two-regime pattern for all 10 macro-related factors: high-risk portfolios earn significantly higher returns than low-risk portfolios following low-sentiment periods, whereas the exact opposite occurs following high-sentiment periods. These findings are consistent with a setting in which market-wide sentiment is combined with short-sale impediments and sentiment-driven investors undermine the traditional risk-return tradeoff, especially during high-sentiment periods.     

CEO Risk‐taking Incentives and Bank Loan Syndicate Structure

This paper investigates the effects of a borrowing firm's CEO risk‐taking incentives on the structure of the firm's syndicated loans. When CEO risk‐taking incentives are high, syndicates are structured to facilitate better due diligence and monitoring efforts. These syndicates have a smaller number of total lenders and are more concentrated, and lead arrangers will retain a greater portion of the loan. Moreover, CEO risk‐taking incentives have a lesser effect on the syndicate structure when lead arrangers have a good reputation and a prior lending relationship with a borrowing firm, while they have a greater effect on the syndicate structure when borrowing firms have low information transparency, are financially distressed or have low growth prospects.     

Corporate social responsibility performance,financial distress and firm life cycle: evidence from Australia

This study examines the association between corporate social responsibility (CSR) performance and financial distress and additionally the moderating impact of firm life cycle stages on that association. Based on a sample of 651 publicly listed Australian firm‐years’ data covering the 2007–2013 period, our regression results show that positive CSR activity significantly reduces financial distress of the firm. In addition, the negative association between positive CSR performance and financial distress is more pronounced for firms in mature life cycle stages. Our results are robust to alternative proxy measures of financial distress, CSR performance and life cycle stages.     

Firm life cycle and debt maturity structure: evidence from China

This study examines the effect of firm life cycle on debt maturity structure (DMS) in China. We reveal that DMS is relatively low in the introduction and recession periods, while long‐term debt ratio of growth companies is high. Companies in booming industries need funds but have difficulty obtaining long‐term loans, whereas companies in recession can use more long‐term loans. The Chow test shows that DMS changed markedly before and after the new normal of China’s economy and the implementation of the ‘mass entrepreneurship and innovation campaign’. It is urgent to address sunset industries to improve the efficiency of resource allocation.     

Firm value in crisis: Effects of firm-level transparency and country-level institutions

Recent empirical research suggests that country-level and firm-level governance institutions are substitutes with respect to their effect on firm value. In this paper we demonstrate that during a crisis these institutions may actually become complements. Specifically, we find that the decline in companies’ valuation during the financial crisis of 2007–2009 was more sensitive to firm-level transparency in countries with stronger investor protection. We propose a theoretical model that reconciles our findings with the results in the literature. In our model, during “normal times” strong firm-level governance is crucial to attract outside financing in countries with weak investor protection, but is less important in countries with good investor protection. During a crisis, however, investment opportunities decline even in countries with strong investor protection, and, as a result, relative importance of firm-level governance increases in such places.     

Institutional trading,investor sentiment,and lottery-like stock preferences

This paper explores the time-varying institutional investor preference for lottery-like stocks. On average, institutional investor holdings reflect an aversion to lottery-like stocks. However, I find that an institutions’ aversion to lottery-like stocks is reduced when investor sentiment is low. Moreover, I find that during low sentiment periods, institutional investors have abnormally high trading profits in more positively skewed stocks. These results suggest that institutions reduce their aversion toward lottery-like stocks during low sentiment periods to profitably trade in lottery-like stocks.     

Investor sentiment,SEO market timing,and stock price performance

This article details an investigation of the impact of investor sentiment on the probability of firms conducting seasoned equity offerings (SEOs) and on stock price performance around and subsequent to SEOs. The results show that investor sentiment has a positive impact on SEO probability and that this impact is stronger for small and young firms. Furthermore, firms conducting SEOs during high sentiment periods experience less severe short-run price drops around the issuance yet more severe post-issue long-run underperformance, compared with firms conducting SEOs during low sentiment periods. These effects of investor sentiment on stock price performance are stronger for small, young, and high market-to-book ratio firms.     

投资者情绪、经理激励契约与企业投资

本文基于中国上市公司经理激励契约安排的制度背景,把经理激励契约纳入投资者非理性分析框架,就投资者情绪与经理激励契约如何相互作用影响企业投资进行了理论分析,并进行了实证检验。结果发现,高管持股会诱发高管利用投机的股市进行过度投资,而与股价弱相关的货币薪酬没有这种作用,而且经理薪酬的这种作用因企业实际控制人性质不同而有所差异。本研究表明高管持股在企业投资决策中具有负面的公司治理效应。
