Stock Exchange Disclosure and Market Development: An Analysis of 50 International Exchanges

This study examines associations between measures of stock exchange disclosure and market development at 50 of the member stock exchanges of the World Federation of Exchanges. We focus on stock exchange disclosure systems (rather than actual company disclosures) because this approach links stock exchange policy with desired outcomes related to market development (such as liquidity, trading activity, and market size relative to gross domestic product). We find strong support for the hypothesis that the strength of the disclosure system (disclosure rules, monitoring, and enforcement) is positively associated with market development, after controlling for legal system, legal protection of investors, market size, and several other potentially relevant explanatory variables.     

Mandatory Portfolio Disclosure,Stock Liquidity,and Mutual Fund Performance

We examine the impact of mandatory portfolio disclosure by mutual funds on stock liquidity and fund performance. We develop a model of informed trading with disclosure and test its predictions using the May 2004 SEC regulation requiring more frequent disclosure. Stocks with higher fund ownership, especially those held by more informed funds or subject to greater information asymmetry, experience larger increases in liquidity after the regulation change. More informed funds, especially those holding stocks with greater information asymmetry, experience greater performance deterioration after the regulation change. Overall, mandatory disclosure improves stock liquidity but imposes costs on informed investors.     

证券交易所交易监管的权责和纪律处分程序

我国有关法律、行政法规对于交易所履行监管证券交易的行政职能的法定权威，并没有提供引导性的、可操作性的规范，依照现行法而推导出的“法定授权”是不明确的或仅具有原则性。这种状况使交易所在履行一线监管职能方面处于两难境地。     

竞争格局中交易所自律管理走势的理论与实践

20世纪90年代以来,就上市资源等方面的市场竞争与交易所自律管理走势之间的关系,在美国产生了激烈争论,出现了“奔向高端”与“奔向低端”雨大观点。“奔向高端”论重要的理论支柱是20世纪80年代兴起的企业“声誉”理论,而“奔向低端”论的主要理论依据是“利益机会主义”理论,二者的争论本质上是“声誉”理论与“利益机会主义”理论的交锋。文章分析认为,市场竞争如何影响自律管理,涉及市场机制、行为动机、利益博弈等复杂命题,在不同国家和地区的证券交易所以及同一交易所的不同历史阶段,表现形式和作用方式也会有诸多差异。文章还以美国、德国、巴西等国的资本市场为样本,对竞争如何影响证券交易所自律管理作了个案实证分析和历史考察。     

The Effectiveness of Price Limits and Stock Characteristics: Evidence from the Shanghai and Shenzhen Stock Exchanges

We examine the effectiveness of price limits on Chinese A shares and investigate the characteristics of those stocks that hit their price limits more frequently. We find that the effect of price limits is asymmetric for the A shares in upward and downward price movements and different for bullish and bearish sample periods. During a bullish period price limits effectively reduce stock volatility for downward price movements, but not for upward price movements; while during a bearish period price limits effectively reduce stock volatility for upward price movements, but not for downward price movements. Second, price limits delay efficient price discovery for upward price movements, but not for downward price movements. However, we do not find evidence to suggest that price limits harmfully interfere with the stock trading processes in the Chinese A share markets. Finally, we find that actively traded stocks hit their price limits more often and tend to hit the lower limit more frequently when overall market conditions are bearish. Stocks with high book-to-market values of equity hit their upper price limits more frequently, while stocks with a high ratio of tradable shares tend to hit their price limits less frequently.JEL Classification: G10, G14, G15     

竞争力、市场微观结构与证券交易所变革

纽约证券交易所和纳斯达克实施的重大并购行动标志着全球证券交易所新一轮并购浪潮的兴起,证券交易所之间的竞争再度趋于白热化.交易所之间的竞争已演变为市场微观结构的竞争.本文对纽约证券交易所和纳斯达克的交易成本进行了比较,无论是上市成本还是交易成本,新兴的纳斯达克都比传统的纽约证交所更胜一筹.因而本文认为有效降低交易成本应是提高交易所核心竞争力的关键所在,而改进交易机制、拓展产品服务以及调整组织架构,可以作为降低交易成本、提高交易所竞争力的具体竞争策略.     

Earnings Performance and Discretionary Disclosure

While the influence of earnings performance on disclosure is a fundamental issue in the disclosure literature, our understanding of this influence is limited. In this paper, I examine a comprehensive set of disclosures from a sample of firms experiencing an extended period of seasonally adjusted earnings increases. I study how these firms adjust disclosure in response to earnings increases, how disclosure changes as the period of strong earnings performance nears an end and how firms disclose during a subsequent period of earnings decline. I find an increase in disclosure during the period of increased earnings. This increase is pervasive across all types of disclosure and tends to be bundled with earnings announcements. The market responds positively to this disclosure. Firms continue to disclose at a high level as they approach earnings declines. However, they shift to disclosures that focus on the positive short-term results and do not discuss the impending decreases. While this behavior is systematic, the market does not appear to anticipate the subsequent earnings declines. Once the firms announce earnings declines, the magnitude of disclosure returns to the level provided prior to the increased earnings.

Mandatory Disclosure,Voluntary Disclosure,and Stock Market Liquidity: Evidence from the EU Bank Stress Tests

We use the EU stress tests and the Eurozone sovereign debt crisis to study the consequences of supervisory disclosure of banks’ sovereign risk exposures. We test the idea that a mandatory one‐time disclosure induces an increase in voluntary disclosures about sovereign risk in the following periods and, through the shift in the voluntary disclosure equilibrium, increases the liquidity of banks’ shares. First, we find that the timing and content of different mandatory disclosure events helps explain the levels of stress‐test banks’ voluntary disclosures about sovereign risk. Second, although the bid‐ask spreads of stress test participants generally increased after the mandatory stress test in 2011, our results suggest that the decrease in market liquidity is entirely attributable to those stress‐test participants that did not commit to voluntarily maintaining the disclosures of sovereign risk exposure.     

A Preliminary Analysis of SASB Reporting: Disclosure Topics,Financial Relevance,and the Financial Intensity of ESG Materiality

At the end of 2018, the Sustainability Accounting Standards Board (SASB) released its corporate reporting standards for material environment, social, and governance (ESG) issues. These SASB standards are analogous to FASB's but deal with ESG activities that help the companies create value over the long term and have been endorsed by large asset management firms such as BlackRock. The authors analyze the quality of ESG reporting by the 91 companies that adopted SASB's framework. While the number of such companies is still small, their results are encouraging, an indication of better things to come. Using three measures of effectiveness, Disclosure Topic Compliance Index (DTCI), Financial Relevance Compliance Index (FRCI), and Financial Intensity Compliance Index (FICI), the authors found that most companies are doing a good to very good job of reporting and companies tend to focus on measures with the highest financial relevance. Scores on these three measures were similar across industry sectors except for a few cases where the DTCI score is low. They presented cases of three SASB standard companies: 1) Sunrun, a residential solar panel company that uses some hazardous materials, 2) Suncor, an integrated oil and gas company, and 3) Target, a retail company in a highly competitive industry needing to keep costs low while also managing an extensive supply chain responsibly. These 91 companies have demonstrated that reporting according to SASB standards can be done well. This success should encourage other companies to follow and the authors offer a seven‐step process to adopt SASB standards.     

The Credibility of Voluntary Disclosure and Insider Stock Transactions

We examine stock price reaction to voluntary disclosure of innovation strategy by high‐tech firms and its relation with insider stock transactions before the disclosure. We find that, despite the qualitative and subjective nature of strategy‐related disclosure, there is positive stock price reaction to the disclosure. The evidence suggests that investors view the disclosure as credible good news. We also find that the disclosure is associated with more positive stock price reaction when it is preceded by insider purchase transactions. This evidence is consistent with insider purchase enhancing the credibility of the disclosure. The credibility‐enhancing effect is found to be stronger for firms with higher degrees of information asymmetry (younger firms, firms with lower analyst following, loss firms, and firms with higher research and development (R&D) intensity). Our evidence also indicates that predisclosure insider purchase is associated with greater future abnormal returns, suggesting that managers are privy to good news shortly before the disclosure.     

Stock Repurchases in Canada: Performance and Strategic Trading

During the 1980s, U.S. firms announcing stock repurchases earned favorable long-run returns. Recently, concerns have been raised over the robustness of these findings. This concern comes at a time of explosive growth in repurchase programs. Thus, we study new evidence from the 1990s for 1,060 Canadian repurchase programs. Moreover, because of Canadian law, we can carefully track repurchase activity monthly. Similarly to the situation in the United States, the Canadian stock market discounts the information in repurchase announcements, particularly for value stocks. Completion rates in Canada are sensitive to mispricing. Trades also appear linked to price movements; managers buy more shares when prices fall.     

Competition and Integration among Stock Exchanges in Europe: Network Effects, Implicit Mergers and Remote Access

The economic theory of network externalities and a simple-game theoretical framework are used to explore the issue of competition among stock exchanges and the possibility of consolidation in the European stock-exchange industry. The paper shows the existence of equilibria where exchanges may decide, even unilaterally, to achieve full compatibility through implicit mergers and remote access, specialising only in trading or listing services. Thus the consolidation of European exchanges into one may occur with a welfare-efficient outcome or with a lock-in to a Pareto-inferior equilibrium, due to the network externalities and the different starting points of the various exchanges. 'Implicit mergers' among exchanges together with remote access are always weakly (in half of the cases, strictly) more efficient than the actual competition. This finding also sheds light on the existence and efficacy, of ATS and rating agencies, which can be viewed respectfully as exchanges specialising in trading and listing services.     

Permanent and Transitory Driving Forces in the Asian-Pacific Stock Markets

This paper uses weekly data from November 1987 through May 1999 to examine whether U.S. or the Japan stock market (or both) is the main driving force behind major movements in eleven emerging Asian-Pacific stock markets. We find a robust cointegrating relation linking each of the emerging market with the two matured markets of the U.S. and Japan. The results also show that the U.S., rather than Japan, is the main permanent force driving the equilibrium relations across all Asian-Pacific markets. In contrast, the effect of the Japanese market on the Asian-Pacific region is only transitory. Therefore, strategic asset portfolios in the Asian-Pacific region should include Japanese stocks to diversify any country specific risks. As to U.S. investors, the persistent influence of the U.S. market may limit long-run diversification gains from Asian-Pacific stocks.     

ESG Integration in Investment Management: Myths and Realities

The number of public companies reporting ESG information grew from fewer than 20 in the early 1990s to 8,500 by 2014. Moreover, by the end of 2014, over 1,400 institutional investors that manage some $60 trillion in assets had signed the UN Principles for Responsible Investment (UNPRI). Nevertheless, companies with high ESG “scores” have continued to be viewed by mainstream investors as unlikely to produce competitive shareholder returns, in part because of the findings of older studies showing low returns from the social responsibility investing of the 1990s. But studies of more recent periods suggest that companies with significant ESG programs have actually outperformed their competitors in a number of important ways. The authors’ aim in this article is to set the record straight on the financial performance of sustainable investing while also correcting a number of other widespread misconceptions about this rapidly growing set of principles and methods: Myth Number 1: ESG programs reduce returns on capital and long‐run shareholder value. Reality: Companies committed to ESG are finding competitive advantages in product, labor, and capital markets; and portfolios that have integrated “material” ESG metrics have provided average returns to their investors that are superior to those of conventional portfolios, while exhibiting lower risk. Myth Number 2: ESG is already well integrated into mainstream investment management. Reality: The UNPRI signatories have committed themselves only to adhering to a set of principles for responsible investment, a standard that falls well short of integrating ESG considerations into their investment decisions. Myth Number 3: Companies cannot influence the kind of shareholders who buy their shares, and corporate managers must often sacrifice sustainability goals to meet the quarterly earnings targets of increasingly short‐term‐oriented investors. Reality: Companies that pursue major sustainability initiatives, and publicize them in integrated reports and other communications with investors, have also generally succeeded in attracting disproportionate numbers of longer‐term shareholders. Myth Number 4: ESG data for fundamental analysis is scarce and unreliable. Reality: Thanks to the efforts of reporting and investor organizations such as SASB and Ceres, and of CDP data providers like Bloomberg and MSCI, much more “value‐relevant” ESG data on companies has become available in the past ten years. Myth Number 5: ESG adds value almost entirely by limiting risks. Reality: Along with lower risk and a lower cost of capital, companies with high ESG scores have also experienced increases in operating efficiency and expansions into new markets. Myth Number 6: Consideration of ESG factors might create a conflict with fiduciary duty for some investors. Reality: Many ESG factors have been shown to have positive correlations with corporate financial performance and value, prompting ERISA in 2015 to reverse its earlier instructions to pension funds about the legitimacy of taking account of “non‐financial” considerations when investing in companies.

Efficiency and Stock Performance in European Banking

Abstract:   Recent competitive pressures have progressively driven banks to strategically focus on generating returns to shareholders. Therefore, the investigation of the determinants of bank performance and their relationship with share prices has become increasingly important. This paper extends the literature on market‐based accounting to examine the relationship between stock prices and efficiency. Specifically, it investigates if changes in stock performance can be explained by changes in operating efficiency, derived by parametric and non‐parametric methods. Results seem to suggest that changes in efficiency are reflected in changes in stock prices and that stocks of cost efficient banks tend to outperform their inefficient counterparts.

ESG Investing in Emerging and Frontier Markets

The authors discuss the benefits of considering material environmental, social, and governance (ESG) factors when investing in emerging and frontier markets. Companies that operate in these markets face a myriad of operating challenges, and management teams that respond to such challenges effectively can achieve superior financial performance over time. They are able to grow faster, achieve higher profitability, reduce their cost of capital, and manage exogenous risks better than their peers. For investment managers, integrating sustainability into the analysis process provides a differentiated lens to identify companies that possess strong competitive advantages that can drive value creation over time. At the same time, it can help investment managers avoid companies that have embedded risks in their business model or operations that may not be entirely visible to the market. Finally, given the early‐stage nature of many of these markets and the sometimes uneven understanding of sustainability issues at a company level, the authors argue that active ownership can be an important driver of alpha generation by fund managers. Engaging constructively with board members and management teams to improve a company's ESG profile can help drive operational improvements, strengthen the risk management function, and upgrade investors’ perception of the quality of the management team.
