Do corporate press releases drive media coverage?

We examine the role of voluntary corporate press releases about firms' financial performance as a stimulus for financial media coverage. We find that there is a spike of media articles on the same day and one trading day following firms' press releases. We provide evidence that managers compete for media attention and can use voluntary press releases to increase their firms' media coverage; a firm's issuance of press releases attracts more media articles about the firm leading to greater abnormal returns and trading volumes. Our results are robust to controlling for firm characteristics, different model specifications as well as regular earnings announcements, which have been the focus of prior literature. We also show that our inferences are not sensitive to managers' duty to disclose material information to investors. Collectively, our findings suggest that media coverage decisions can be influenced by a firm.     

CEO overconfidence and the tone of press release

This paper examines how CEO overconfidence affects the tone of press releases. Using option-based proxies for CEO overconfidence, I find that over the 2000–2018 period, the press releases issued by firms with overconfident CEOs have more positive tone and receive more positive market reactions. The relation between CEO overconfidence and the tone of press releases is stronger among firms with good operating performance and concentrated in investment-related news but is insignificant for earnings news. These findings suggest that CEO overconfidence leads to biases in press releases.     

Corporate misconduct,media coverage,and stock returns

This study examines the impact of increased investor attention to corporate misconduct (CM) on stock returns. We show that media coverage provides an important channel through which investor awareness of corporate wrongdoings can be enhanced. Using a unique research setting in Korea based on text analysis during the 2008–2020 period, we find that investors exhibit short-term adverse reactions to CM events. More importantly, the increased social awareness of CM issues through media coverage leads investors to penalize firms more severely. We also find that the adverse reaction to CM events is more prominent for firms with a greater negative media tone and surprise. The combined evidence supports the investor attention theory. Furthermore, the negative effects of CM on stock returns are smaller for firms with positive Corporate Social Responsibility (CSR) and Environmental, Social, and Governance (ESG) reputations, consistent with the insurance theory.     

Sentiment stocks

To study how investor sentiment at the firm level affects stock returns, we match more than 58 million social media messages in China with listed firms and construct a measure of individual stock sentiment based on the tone of those messages. We document that positive investor sentiment predicts higher stock risk-adjusted returns in the very short term followed by price reversals. This association between stock sentiment and stock returns is not explained by observable stock characteristics, unobservable time-invariant characteristics, market-wide sentiment, overreaction to news, or changing investor attention. Consistent with theories of investor sentiment, we find that the link between sentiment and stock returns is mainly driven by positive sentiment and non-professional investors. Finally, exploiting a unique feature of the Chinese stock market, we are able to isolate the causal effect of sentiment on stock returns from confounding factors.     

Investor and price response to patterns in earnings surprises

As part of their model to explain short-term positive and long-term negative auto-correlation in stock returns, Barberis, Shleifer, and Vishny [1998. A model of investor sentiment. Journal of Finance 49, 307–345] suggest that investors may extrapolate trends in earnings performance. I test this portion of their model by examining investor trading patterns in firms that experience consecutive same-sign earnings surprises. Consistent with their model, after controlling for regularities in trading activity, I find that the net buying of small investors increases with the number of consecutive positive earnings surprises. I further find that purchasing activity of small investors subsequent to consecutive positive surprises is significantly negatively correlated with returns throughout the remainder of the year. These results suggest that such investors are not simply rationally updating after public news announcements. My results are robust to controlling for auto-correlation in earnings surprises.     

Information dissemination on intellectual capital in mergers and acquisitions: purchase price allocations,press releases and business press

In order to reduce information asymmetries in relation to a firm's current decisions and long-term strategy, firms must consistently provide information to stakeholders. This paper investigates intellectual capital (IC) information disclosed in mergers and acquisitions (M&A) provided through three different disclosure channels (voluntary press releases, related newspaper articles and subsequent mandatory corporate disclosures in the notes to the financial statements). For a sample of 215 randomly selected US and European M&As, we analyse 215 press releases, 1025 newspaper articles and 215 purchase price allocations. Our findings suggest that IC disclosure in press releases is not perceived as informative and qualitative forward-looking IC information in voluntary corporate disclosures appears to lack credibility. Moreover, we empirically demonstrate interdependencies across the three disclosure channels. The business press seems to filter IC information provided in press releases. The amount of IC disclosure in the notes to the financial statements is positively associated with prior IC disclosure in newspaper articles, but negatively associated with IC disclosure in press releases. The managements of acquirer firms appear to pay attention to news coverage and public opinion. However, both voluntary and mandatory corporate disclosures appear to substitute rather than complement each other.     

Opportunistic disclosure in press release headlines

This paper examines managerial, self-serving, disclosure practices in the headlines of press releases announcing annual results. Headlines are a framing feature that can be used to capture and retain attention with the ultimate intention of affecting the thoughts and feelings of readers, thus influencing their opinions. Therefore, headlines have a key role in a company's communication strategy. Using a large sample of Spanish listed companies for the years 2005 and 2006, we provide evidence of persistent impression management in press release headlines. Companies, irrespective of whether they perform well or badly, are inclined to stress good news and downplay bad news. Companies with very small profits report surprising amounts of good news. We provide evidence that companies are selective in the performance figures they include in the headlines of press releases. In particular, the disclosure of profits or sales figures in press release headlines is also associated with earnings performance. Finally, we find that larger firms are more likely to issue press releases than smaller ones, consistent with the theory that highly visible firms face a greater demand for information transparency.     

Managerial incentives for discretionary disclosure: evidence from management leveraged buyouts

Managers in management leveraged buyout (MBO) firms prefer to purchase their firms at a low offer price. This motive gives them a clear incentive to make pessimistic discretionary disclosures. Using a sample of press releases, I find that managers involved in their firms’ MBO selectively release negative disclosures to denigrate their firm just before the MBO transaction when compared with prior period: they issue more bad news disclosures and more pessimistic quotes. Additionally, they issue less optimistic quotes, fewer good news disclosures, less positive earnings forecasts, and they manage earnings downwards. I control for factors that may not be caused by managers’ purchase motives by comparing the MBO sample with a third-party leveraged buyout sample where management is not involved in the buyout and with a performance-matched control sample. I find that the disclosure of MBO firms becomes significantly more pessimistic than the leveraged buyout firms where management is not involved in the transaction and significantly more pessimistic than the performance-matched control sample.     

The impact of public information on investors

This study investigates the trading behavior of institutional and individual investors around both firm-specific news releases in the Wall Street Journal and macro-economic announcements. For the firm-specific news releases we find that investors conduct a high degree of trading around news releases, especially earnings and dividend news. Institutions buy and sell on both good and bad news, while individual investors only trade on good news. The length of the news article (visibility) is also an important attribute to motivate individual investor trading. Lastly, both institutions and individuals buy large firms after good economic news and sell large firms after bad economic news. The trading of small firms does not appear to be motivated by macro-news.     

Managerial incentives for attracting attention

This paper studies the mechanisms which motivate managers to engage in cheap talk and attract the market's attention in a credible way. We consider stock split announcements, voluntary earnings forecasts, and press releases issued by firms to the media as proxies for managerial cheap talk. We show that: (a) managerial performance‐related pay contracts incentivize executives to attract attention; (b) analysts increase their coverage of firms following cheap talk; and (c) chief executive officers are punished for attracting attention when market prices do not increase following cheap talk. The results are stronger for firms which are most in need of attention.     

Retail investor attention and firms' idiosyncratic risk: Evidence from China

This paper investigates retail investor attention to firms' idiosyncratic risk in China. We use the Baidu search index as a proxy for attention and test its effect on Chinese firms' idiosyncratic risk from 2011 to 2017. Our empirical results suggest investor attention has a positive impact on firms' idiosyncratic risk. This effect is robust to possible endogeneity issues and alternative channels of effects and is stronger for small firms. Additional analysis finds that the effect of our proxy for attention on firms' idiosyncratic risk is stronger than investor sentiment and traditional attention proxies, including announcements, media news, analyst ratings, and brokerage reports. These findings provide evidence of retail investor attention could increase firms' contemporaneous idiosyncratic risk, and decrease firms' subsequent period risk.     

Voluntary disclosure of accruals in earnings press releases and the pricing of accruals

This study investigates firms’ decisions to disclose accruals information in earnings press releases versus to provide it only in 10-Q filings and the impact of this disclosure on the pricing of accruals. I find that firms disclose accruals in their press releases when earnings alone are a weak indication of cash flow performance and that following these disclosures the accruals information is fully impounded into stock prices. The evidence suggests that when investor demand for accruals is likely to exist and firms disclose the information in earnings press releases, the mispricing typically associated with accruals is mitigated.

Retail investor attention and corporate innovation in the big data era

This paper explores the corporate governance role of retail investor attention from the perspective of corporate innovation. Using a sample of Chinese listed firms from 2011 to 2019, we find that retail investor attention significantly promotes corporate innovation. Thisresult ise robust to a series of robustness checks to address potential endogeneity concerns. I further conclude that the impact of retail investor attention on corporate innovation is mainly through alleviating a firm's financial constraints and deterring agency costs. In addition, such effects are more pronounced in firms with higher media and analyst coverage as well as those with more overconfident CEOs. The results provide empirical evidence of the corporate governance function of individual investors in the current digital era.     

Sensitivity to sentiment: News vs social media

We explore the rapidly changing social and news media landscape that is responsible for the dissemination of information vital to the efficient functioning of the financial markets. Using the sheer volume of social and news media activity, commonly known as buzz, we document three distinct regimes. We find that between 2011 and 2013 the news media coverage stimulates activity in social media. This is followed by a transition period of two-way causality. From 2016, however, changes in levels of social media activity seem to lead and generate news coverage volumes. We uncover similar evolution of lead-lag pattern between sentiment measures constructed from the tonality contained in textual data from social and news media posts. We discover that market variables exert stronger impact on investor sentiment than the other way around. We also find that return responses to social media sentiment almost doubled after the transition period, while return responses to news-based sentiment almost halved to its pre-transition level. The linkage between volatility and sentiment is much more persistent than that between returns and sentiment. Overall, our results suggest that social media is becoming the dominant media source.     

媒体关注度对新股表现的影响——来自中国股票市场的证据

新闻媒体对证券投资的影响日趋重要,它会通过影响投资者的心理和行为而影响资产价格。首次公开发行的股票（IPOs）由于倍受媒体关注,从而会在上市以后的价格表现上产生一定的影响。本文选取2006年6月至2008年6月上市的246只首次公开发行的股票作为样本,以百度新闻搜索到包含股票名称的新闻数量作为媒体关注度的衡量指标,实证检验了媒体关注度对新股表现的影响。本文得出结论：媒体关注度通过影响投资者情绪,对新股短期累积超额收益产生正的影响,而对长期累积超额收益产生负的影响。同时发现,媒体关注度高的新股,其发行价格也相对较高。     

投资者关注度与股票市场——以PM2.5概念股为例

近年来雾霾成为中国社会的热点话题,而雾霾频发导致PM2.5概念股受到投资者广泛的关注。本文结合现实环境问题,研究投资者通过对环境的关注度继而对与环境相关的股票的影响。具体而言,本文探究投资者对雾霾和PM2.5概念股的关注度对PM2.5概念股的影响。分析发现投资者对雾霾和PM2.5概念股的关注度的增加能拉升PM2.5概念股的股价。投资者对雾霾的关注度和PM2.5概念股的收益率显著正相关。关注度的增加同时也提高PM2.5概念股交易的活跃程度以及PM2.5概念股涨停的可能性。此外,本文发现正面的新闻报道会拉升PM2.5概念股的股价而负面的新闻报道会降低其股价。最后,本文通过讨论内生性和异质性等一系列稳健性检验进一步验证上述结论。     

Media coverage and investment efficiency

We examine the effect of media coverage on firm-level investment efficiency. We find that media coverage reduces under-investment but increases over-investment. The negative effect of media coverage on under-investment is more pronounced in firms affected by greater information asymmetry and poorer corporate governance. The positive effect of media coverage on over-investment is driven by media-induced CEO overconfidence. Additional results show that both investment- and non-investment-related news coverage decrease under-investment, while non-investment-related news coverage is more influential in increasing over-investment. In general, higher news optimism is associated with less under-investment but more over-investment. Moreover, media coverage affects investment efficiency through its information dissemination rather than information creation function. Collectively, our results suggest that firms’ media visibility promotes more over-investment than under-investment.     

Anticipated Earnings Announcements and the Customer–Supplier Anomaly

I test whether the anticipation of earnings news stimulates acquisition of customer information and mitigates returns to the customer–supplier anomaly documented by Cohen and Frazzini (“Economic Links and Predictable Returns.” The Journal of Finance 63 (2008): 1977–2011). I find that attention to a firm's publicly disclosed customers increases shortly before the firm announces earnings, and that customer stock returns predict supplier stock returns shortly before, but not after, the supplier's earnings announcement. I further find some evidence that these predictable returns are increasing in the level of customer information acquisition. These results are unique to anticipated disclosure events and suggest that anticipation of supplier earnings announcements resolves investor limited attention to customer information and accelerates price discovery of customer news.     

Who Writes the News? Corporate Press Releases during Merger Negotiations

Firms have an incentive to manage media coverage to influence their stock prices during important corporate events. Using comprehensive data on media coverage and merger negotiations, we find that bidders in stock mergers originate substantially more news stories after the start of merger negotiations, but before the public announcement. This strategy generates a short‐lived run‐up in bidders' stock prices during the period when the stock exchange ratio is determined, which substantially impacts the takeover price. Our results demonstrate that the timing and content of financial media coverage may be biased by firms seeking to manipulate their stock price.     

The effect of bond rating changes on common stock prices

The evidence in this paper suggests that downgrades by both Moody's and Standard and Poor's are associated with negative abnormal stock returns in the two-day window beginning the day of the press release by the rating agency. Significant negative abnormal performance can still be detected after eliminating observations containing obvious concurrent (potentially contaminating) news releases. There is little evidence of abnormal performance on announcement of an upgrade. Significant abnormal returns are associated with announcements of additions to the Standard and Poor's Credit Watch List, if either a potential downgrade or a potential upgrade is indicated.
