Information Content of Insider Trading Around Corporate Announcements: The Case of Capital Expenditures

There is gathering evidence of insider trading around corporate announcements of dividends, capital expenditures, equity issues and repurchases, and other capital structure changes. Although signaling models have been used to explain the price reaction of these announcements, a usual assumption made in these models is that insiders cannot trade to gain from such announcements. An innovative feature of this paper is to model trading by corporate insiders (subject to disclosure regulation) as one of the signals. Detailed testable predictions are described for the interaction of corporate announcements and concurrent insider trading. In particular, such interaction is shown to depend crucially on whether the firm is a growth firm, a mature firm, or a declining firm. Empirical proxies for firm technology are developed based on measures of growth and Tobin's q ratio. In the underlying “efficient” signaling equilibrium, investment announcements and net insider trading convey private information of insiders to the market at least cost. The paper also addresses issues of deriving intertemporal announcement effects from the equilibrium (cross-sectional) pricing functional. Other announcement effects relate the intensity of the market response to insider trading, variance of firm cash flows, risk aversion of the insiders, and characteristics of firm technology (growth, mature, or declining).     

Corporate Governance and Information Efficiency in Security Markets

This paper investigates a neglected topic in corporate governance research; namely, do governance characteristics affect the market reaction to news? The topic is important given the emphasis by governance regulations and codes of best practice on the need for greater transparency of corporate activities. For the first time in the corporate governance literature, we show that corporate governance characteristics (particularly the presence of founding family directors and gender diverse boards) affect the market reaction to company specific news. The results of the paper point to the analysis of the impact of governance characteristics on the market reaction to news being a new and complementary research agenda within corporate governance.     

媒体公关、投资者情绪与证券发行定价

本文研究了拟上市公司通过专门针对媒体的公关活动影响其证券发行定价的内在机制。结果发现:公司可以通过投入媒体公关费用来增加媒体对于该公司的新闻报道量,这些报道在性质上属于正面的广告宣传,而正面新闻能够显著提高投资者对该公司的关注程度和乐观情绪;乐观情绪越强,则参与证券发行的投资者人数越多,需求量越大,进而导致证券发行价格的上调幅度越大。但是在长期内,当证券交易价格逐渐回归于实际价值时,发行前关注度越高的证券,其长期回报率越低。本文的研究意味着新闻媒体在证券发行中的宣传推介功能与其公司外部治理人的身份存在冲突。     

The Industry-Wide Implications of Dividend Omission and Initiation Announcements and the Determinants of Information Transfer

In examining the industry-wide implications of dividend omission and initiation announcements, this study finds distinct industry responses for these two events. Specifically, dividend omission announcements have a significantly negative impact on the valuations of industry-related firms. Factors influencing this industry reaction include the Herfindahl index of the announcing firm's industry, the two-day abnormal return of the announcing firm, and its trading status (Nasdaq or NYSE/AMEX). Unlike dividend omissions, dividend initiations evoke a competitive (or negative) response from industry-related firms. The degree of homogeneity in the announcing firm's industry, the announcing firm's abnormal return and its size affect this industry response.     

The Long-Term Performance of Corporate Bonds (and Stocks) Following Seasoned Equity Offerings

Previous studies document negative long-term abnormal stockreturns following seasoned equity offering (SEO) issuances andconclude that markets are inefficient. Other studies, however,argue that these results are a manifestation of risk mismeasurement(i.e., the bad-model problem), not market inefficiency. We testthe efficient market hypothesis (EMH) and avoid the bad-modelproblem by examining the long-term performance of our samplefirms' bonds and stocks following their SEOs. Our results areinconsistent with the EMH. We also provide evidence that SEOstransfer wealth from shareholders to bondholders because SEOsreduce default risk.     

Market Reactions to Corporate Governance Ranking Announcements: Evidence from Taiwan

This study examines whether market participants react to the announcements of corporate governance ranking exercises. As a regulatory innovation, the Financial Supervisory Commission in Taiwan initiated and administered two ranking exercises, one in 2015 and the other in 2016, on all publicly listed companies. Adopting anchoring-and-adjustment theory, the study predicts that market participants will react strongly to the second announcement if the ranking obtained in the second exercise turns out to be better than the ranking in the first round. Employing an event study methodology, the study shows that market participants react positively and significantly to firms ranked in the top 50% in the second corporate governance exercise. Their reactions to the announcement are even stronger among those that did not list in the top 20% in the first exercise, but made it into the top 50% in the second one. Overall, our analyses support that anchoring-and-adjustment theory effectively explains market participants’ behaviour. Since the monitoring of the board of directors and investors may not effectively mitigate the potential moral hazard committed by family owners/executives, our empirical evidence demonstrates that a ranking exercise probably can be employed to supplement routine corporate governance disclosures made in annual reports, in order to strengthen the check-and-balance mechanism and reduce the risk of principal–principal conflicts. In conclusion, we discuss the implications of the research findings and propose directions for future studies.     

The Intra-Industry Effects of Going-Private Transactions

We demonstrate that bids to take firms private generate significantly positive valuation effects for industry rivals of target firms. These valuation effects cannot reflect either synergy or monopoly since no consolidation of operating firms is involved in such transactions. Participation by buyout specialists in the bid does not significantly affect these gains. Bids by outsiders and bids by incumbent managers generate similar valuation effects for industry rivals. The effect on share prices of industry rivals is inversely related to the capitalized values of rival firms relative to the target firm. We also report valuation effects for target firms.     

Intra-lndustry Effects of Corporate Capital Investment Announcements

We examine how announcements of corporate capital investments by one firm affect the stock prices of its competitors. We find that on average, rivals experience a signifi cantly negative valuation effect. The results suggest that for the sample as a whole, the competitive effect dominates the contagion effect. We further examine various factors that could potentially explain the heterogeneous intra-industry effects of capital investment announcements. We find that rivals' share prices are more adversely affected when the announcer experiences a higher announcement effect or is the first mover in the industry. We also show that rivals experience a greater wealth loss when they have poorer investment opportunities or higher financial leverage.     

The Impact of the Source and Sequence of Information in Primary Equity Offerings

Empirical studies of the announcement effects of equity offerings have generally defined the event date as the earlier of the SEC registration date or the first mention in the Wall Street Journal (WSJ), the implicit assumption being that the two types of announcements are equally informative. This study examines whether the source of the event announcement might influence a study's results and whether subsequent announcements from other sources elicit a market reaction. Specifically, this paper investigates whether Dow Jones News Wire (DJNW) announcements that differ in timing from either of these information events elicit a market response and, more important, whether impacts from the DJNW announcements alter the validity of the widely used methodology. The results of the paper indicate that, for issues that are not mentioned in the WSJ Index, there is a negative and significant return on the registration date. However, no matter whether the registration occurs before or after its mention on the DJNW, the share price reaction is greater from mention on the DJNW than at registration. This finding leads to the conclusion that the DJNW should be used as the event date and that press coverage     

On the Use of Intra-Industry Information to Improve Earnings Forecasts

We investigate whether earnings forecasts are improved by earlier earnings disclosures by firms in the same industry. We find improvements for time series forecasts, but not for analysts' forecasts. Considering prior earnings announcements reduces correlations between forecast errors and security price reactions to earnings announcements, even when incorporating these announcements improves forecast accuracy. Our explanation for this anomaly, which is supported by additional analysis, is that intra-industry information facilitates predicting transitory, rather than permanent, earnings components. The question of whether information transfers improve earnings forecasts provides the context for the analysis, but the primary contribution is the documentation of intra-industry information transfers in a setting other than capital markets.     

The Pricing of Initial Public Offerings: A Dynamic Model with Information Production

This paper presents an information-theoretic model of IPO pricing in which insiders sell stock in both the IPO and the secondary market, have private information about their firm's prospects, and outsiders may engage in costly information production about the firm. High-value firms, knowing they are going to pool with low-value firms, induce outsiders to engage in information production by underpricing, which compensates outsiders for the cost of producing information. The information is reflected in the secondary market price of equity, giving a higher expected stock price for high-value firms.     

The Interpretation of Information and Corporate Disclosure Strategies

This paper analyzes a setting in which a firm's manager can credibly disclose facts, but not their valuation implications. Consequently, he is uncertain as to how those disclosed facts will be interpreted by investors. Introducing such uncertainty affects the manager's disclosure strategy in two important ways. First, it becomes a function of the market's prior valuation of the firm since that valuation provides a clue as to how future disclosures are likely to be interpreted by investors. Second, the disclosure strategy is no longer characterized, in general, by a single good news/bad news partition of the manager's private information.     

朝花夕拾

常想在纷扰中寻出一点闲静来,然而委实不容易。常把自己置于无限忙碌的境界,忘却生命贵在行走的真谛。一花一世界,一方一争土。每一幅图画,都是有生命的故事,或是完美的,或是残缺的,以其特有的魅,证明着自己存在的价值。     

The Impact of Global Equity Offerings

This article examines the impact of U.S. firms issuing equity in multiple markets. We compare the stock price reactions to announcements of global equity offers to a control group of issues offered exclusively in the domestic U.S. market. All else equal, the adverse price reaction that typically accompanies equity issuance is reduced by 0.8 percent when some shares are sold abroad. The overall evidence suggests global offers are effective in expanding demand and reducing the price pressure effects associated with share issuance. The beneits of global offers appear to be associated with an increase in the number of foreign shareholders.     

社保基金持股与企业盈余质量:A股上市公司的证据

本文利用中国A股上市公司2006-2015年的数据,研究社保基金持股对上市公司盈余质量的影响。我们用上市公司财务重述作为测度盈余质量的指标,发现社保基金持股能够显著降低企业发布财务重述的概率,这表明社保基金对上市公司盈余质量的提高具有促进作用。并且,社保基金的这一治理作用在国有企业、内部治理水平较差以及市场化程度较低地区的上市公司中更加显著。通过双重差分模型和安慰剂检验等方法弱化了内生性问题之后,以上结论依然成立,说明社保基金持股和盈余质量提升之间存在因果关系,我们称之为社保基金的公司治理作用。进一步研究发现,社保基金可以通过抑制控股股东资金占用、增加机构调研次数等途径提升被持股公司的盈余质量。本文有助于认识和评估社保基金持股对于上市公司的监督与治理作用。     

The Determinants of Intra-Industry Trade in Insurance Services

In light of the growing significance of trade in financial services, and the emphasis placed on trade in financial services during the Uruguay round of trade negotiations, this article is the first study of the determinants of intra‐industry trade (IIT) in insurance services. The article analyzes and measures the magnitude of IIT in insurance services for the United States. The empirical results of the determinants of IIT indicate that foreign direct investment in insurance services (FDI) is a significant contributor to the volume of trade in insurance services. These empirical findings confirm the new theoretical trade models that, unlike the traditional trade theory that considered trade and foreign direct investment in insurance services as substitutes, trade and FDI complement each other and hence multinational insurance companies are contributing to an increase in the volume of trade in insurance services. Furthermore, this study shows that trade intensity between the United States and its trading partners leads to product differentiation in insurance services and hence an increase in consumer welfare.     

Does Shareholder Composition Matter? Evidence from the Market Reaction to Corporate Earnings Announcements

We examine whether institutional ownership composition is related to parameters of the market reaction to negative earnings announcements. When firms report earnings below analysts' expectations, the stock price response is more negative for firms with higher levels of ownership by momentum or aggressive growth investors. There is no evidence, however, that these institutions cause an “overreaction” to earnings news. Ownership structure is also related to trading volume and to stock price volatility on days around earnings announcements. Our findings are consistent with the idea that the composition of institutional shareholders effects stock price behavior around the release of corporate information.     

The Diversification Effects of Initial Public Offerings

Abstract:  A firm's stock becomes publicly tradable through an initial public offering (IPO). This study suggests a portfolio diversification perspective to explore IPOs. We examine whether investors can gain diversification benefits by adding an IPO portfolio to a set of benchmark portfolios sorted by firm size and book-to-market ratio. Using US IPOs from 1980-2002, we find that adding a value-weighted IPO portfolio does lead to a statistically and economically significant enlargement of the investment opportunity set for investors relative to investing solely in a set of benchmark portfolios. Specifically, the Sharpe ratio of the tangency portfolio increases by 5.50% on average after including IPO stocks. Furthermore, IPOs associated with prestigious lead underwriters are the main source of this augmentation of the mean-variance investment opportunity set. Finally, our study implies that issuing IPO exchange traded funds or similar products can provide diversification gains to investors.     

论财务会计信息在公司治理中的作用

财务会计信息对于公司治理具有重要意义。高质量的会计信息可以降低管理层与外部人之间的信息不对称,从而有助于解决逆向选择和道德风险问题;信息披露自身可以对管理层形成有效的约束,促使管理层强化受托责任,并可以为相关主体提供治理所需信息,从而加强外部人对管理层的监督和制约;通过降低对其他高成本治理机制的需求,高质量的会计信息还可以有效地降低公司治理的整体成本,提高治理效率。因此,财务会计信息是实现公司治理目标、保护投资者利益的重要工具。我国应当不断地完善会计准则,并加强会计监管,以提高会计信息质量,更好地为公司治理服务。
