Purpose – This study examines both the short- and long-term share price reaction to announcements of financial restatements cited in the U.S. General Accounting Office (2006) database.

Methodology – It uses the augmented four-factor Fama-French model for assessing share price reaction.

Findings – The study finds that the average cumulative abnormal return (CAR) for a sample of 553 restatements (by 437 companies) is significantly negative (−1.58) for the three-day window surrounding the day of announcement. The average CAR for the one-year period prior to the announcement (−9.6%) and for each of the four years after the announcement is negative as well, with the average CAR for the four years adding up to −22%. The study also documents differences in CARs based on the entity prompting the restatement (company, auditor, and Securities and Exchange Commission), the reason behind the restatement (revenue, cost, reclassification of item, etc.), and for one-time versus repeat offenders.

Social implications – Taken together, the findings indicate that financial restatements impose significant short-term as well as long-term costs on shareholders.

Originality/Value – The evidence about long-term share price reaction to financial restatements is missing in prior research. The relationship between long-term and short-term share price reaction to financial restatements fails to suggest systematic over/underreaction by the market.

Recent research has examined the effect of the Financial Services Modernization Act of 1999, more commonly known as the Gramm–Leach–Bliley Act (GLB), on the market value of U.S. commercial banks, life insurers, property-liability insurers, thrifts, finance companies, and securities firms. This study fills a gap in our understanding of the Act by measuring the price and trading volume effects of the GLB on U.S.-listed foreign banks. A primary contribution of this study is to examine the role, if any, of two corporate governance perspectives, the stakeholder (code law), and shareholder (common law) models, in a cross-sectional analysis of foreign bank market reaction to the GLB.

Using a generalized least squares (GLS) portfolio approach, Corrado's rank statistic, and confirmed by the traditional market model approach, we find significant negative share price reactions to certain legislative announcements surrounding the passage of the GLB. Trading volume reactions corroborate the significant share price responses. In general, our results indicate that investors in foreign banks reacted negatively to key legislative action. In a cross-sectional analysis, younger, higher-risk foreign banks with less concentrated ownership and more subordinated debt from countries with higher quality accounting standards appear to have more positive (or less negative) share price reactions.

This study examines share price reaction to the enrollment by companies in the Children’s Food and Beverage Advertising Initiative. We find that, on average, in the month of enrollment, shareholders of companies that join the CFBAI experience abnormal return of −3% and so do the shareholders of the immediate competitors that do not join the initiative. However, over the subsequent five years, while the shareholders of companies enrolled in the initiative experience an average abnormal return of +16.6%, that of non-enrolled competitors experience a further abnormal return of −34%. The abnormal returns for the two groups (at the time of enrollment and over the subsequent five years) are uncorrelated and so benefitting at the expense of competitors does not appear to be the motive for enrolling in the CFBAI. The study also provides comparison of number of employees and other important financial ratios before and after enrollment in the CFBAI for the two groups.

This chapter delves into the impact of digital initiatives on firms and sheds light on how they can be explained through market reactions and the resource/capabilities mechanism. By providing a novel conceptual framework that reflects the potential impact of digital initiatives on the sensing, seizing and transforming capabilities of dynamic capabilities, this chapter reveals the tremendous potential of digital initiatives to help firms become more adaptive to their environment and create sustainable competitive advantages that elicit positive market responses. This conceptual framework represents an original contribution to the literature. It enhances the understanding of the resource-based view and efficient market hypothesis, providing a fresh perspective on the influence of digital initiatives on firm performance and the dynamic capabilities mechanism that has hitherto been overlooked. As a result, this chapter enables researchers to develop testable hypotheses that examine the causal relationships between digital initiatives, dynamic capabilities and market performance using robust quantitative research methods. Furthermore, this chapter offers valuable insights for managers seeking to develop a more focused approach to digital transformation and enhance their competitive advantage. By exploring the impact of digital initiatives on sensing, seizing and transforming capabilities, managers can gain a deeper understanding of how they can leverage digital initiatives to improve their organisational performance and respond more effectively to the demands of an ever-changing landscape.

We study the information content of issuer credit rating changes announced by a group of six Chinese credit rating agencies. We conduct an event study, and we use multivariate regression analyses to identify factors driving abnormal stock returns. Our results confirm prior findings for Western countries that downgrades are associated with significant negative abnormal returns. However, upgrades and positive or negative rating outlooks do not seem to have information content. While we cannot find differences in information content conditional on which rating agency issues the downgrade, we find that abnormal returns may vary with the target firm’s industry. In addition, the magnitude of stock price reactions to rating downgrades seems to be related to the business cycle to some extent. With respect to the role of the industry in explaining the information content of rating changes, our results may be biased due to small sample size. Nevertheless, they illustrate that the role the industry plays in explaining investor behavior may deserve special attention in future research. Our findings imply that new rating information seems to be processed quickly in the Chinese stock market, and that market reactions to rating signals are largely in line with what has been observed for Western stock markets. Both observations lend credibility to observable stock prices. The chapter sheds new light on the relevance of Chinese credit rating agencies from an equity investor’s perspective and confirms similarities between the Chinese and Western stock markets with respect to the way rating signals are processed by investors.

To explain for doctoral students and new faculty, the appropriate techniques for using event study methods while identifying problems that make the method difficult for use in the context of African markets.

We review the finance and strategy literature on event studies, provide an illustrative example of the technique, summarize the prior use of the method in research using African samples, and indicate remedies for problems encountered when using the technique in African markets.

We find limited use of the technique in African markets due to limited data availability which is attributable to problems of infrequent trading, thin markets, and inadequate access to free data.

Our review of the literature on event studies using African data is limited to English-language journals and sources accessible through our library research databases.

More often, researchers will need to use nonparametric techniques to evaluate market responses for companies in or events affecting the African markets.

We make a contribution with this chapter by giving a more detailed description of event study methods and by identifying solutions to problems in using the technique in African markets.

The central bank policy instruments have become less effective in an environment where economies are integrated with sophisticated financial products. We argue that economic stability is a function of interactions between financial and commodity markets. We utilize MGARCH models to identify volatility comovements between these markets in the United States since 2000. Our results suggest that financial markets have strong impacts on prices and volatility in commodity markets which could be due to intertemporal capital mobility. Thus, understanding commodity markets is inseparable from understanding financial market activities, and must now be included in an economic equation to achieve an effective policy.

We investigate institutional investors’ trading behavior of acquiring firm stocks surrounding merger activities for the period 1992–2001. We label investment companies and independent investment advisors as active institutions and banks, nonbank trusts, and insurance companies as passive institutions. We analyze the trading behavior of active and passive institutions surrounding merger announcements and their eventual resolution. Our results indicate that active institutions significantly increase their holdings of acquiring firm stocks for mergers with higher announcement period abnormal return and this increase is more pronounced for stock mergers than cash mergers. Active institutions display preference for stock proposals at the merger announcement on the basis of their prior beliefs and this is explained by the “overreaction phenomenon.” However, they update their beliefs between announcement and final resolution as more information arrives into the market. Finally, active institutions appear to correct their overreaction behavior by displaying their greater preference for cash proposals as compared to stock proposals at the quarter of eventual outcome. The trading behavior of passive institutions suggests that these institutions disregard the market response of merger announcement in trading acquiring firm stocks at the announcement quarter. The passive institutions gradually update their beliefs and utilize the information released at the announcement in rebalancing their portfolios at the final resolution.

“Corporate governance” refers to the top management process that manages and mediates value creation for, and value transference among, various corporate claimants (including the society-at-large), in a context that simultaneously ensures accountability toward these claimants (Sundaram, Bradley, Schipani & Walsh, 2000, p. 112).
