Value relevance of the new environmental enforcement regime in China

Curbing environmental pollution has become a key priority in China, as reflected in the adoption of policies such as “New Normal” and the takeover of regulatory environmental enforcement by the top leadership of the central government in 2015. In this paper, we use a dataset of publicly-traded firms in the Shanghai and Shenzhen stock exchanges and the event study methodology to gauge the reaction of the investor class to the new environmental enforcement regime. Our results indicate that, together, the announcement and implementation of the new enforcement regime spurred a significant decline of over $29 billion in shareholder value of polluting companies, suggesting that capital market participants expect increased regulatory costs for targeted companies. We also find that neither political connections nor firm size mitigated the severity of the market losses. Instead, larger firms and state-owned enterprises with excess capacity experienced bigger declines in market value.     

The Information Contained in Reconciliations to Earnings Based on US Accounting Principles By Non-US Companies

To improve comparability of financial statements across countries, the US Securities and Exchange Commission (SEC) requires non-US registrants to either issue financial statements based on US Generally Accepted Accounting Principles (GAAP) or provide in their footnotes a reconciliation of their foreign accounts to their US GAAP counterparts. The New York Stock Exchange has requested the elimination of this requirement on the basis that it serves as a barrier to non-US companies that desire to enter the US market. The SEC maintains that the reconciliations provide important information to investors when assessing the value of a company's stock. This study investigates the information content claim made by the SEC. An event study methodology is utilised that measures the stock price reaction within a short window surrounding the SEC filing date of the firm's 20-F (analogous to the 10-K for US firms). A significantly positive correlation is documented between the stock price reaction and the change in the aggregate reconciliation. This result implies that US GAAP disclosures provide information to the market when the 20-F arrives at the SEC.     

Are Banks Still Special? New Evidence on Their Role in the Corporate Capital‐Raising Process

Bankers appear to play a special role in providing commitment-based financing to corporations. This type of lending is important not only for small firms that lack access to public debt markets but for large and medium-size companies as well. For such companies, commitment-based financing provides access to debt capital that becomes valuable when the firm has an immediate need for funding but interest rates in public debt markets are prohibitively high, or the firm is undervalued by the market. A good example of this was provided by the Asian crisis in the last quarter of 1998, when $10 billion of commercial paper was retired and $20 billion of net new commercial loans were booked. The authors also suggest that the fact that commitment-based financing is used by larger companies when they believe themselves to be undervalued in the market is probably the best explanation of why announcements of these types of loans elicit a positive stock price reaction.     

The market value impact of operational loss events for US banks and insurers

This paper conducts an event study analysis of the impact of operational loss events on the market values of banks and insurance companies, using the OpVar database. We focus on financial institutions because of the increased market and regulatory scrutiny of operational losses in these industries. The analysis covers all publicly reported banking and insurance operational risk events affecting publicly traded US institutions from 1978 to 2003 that caused operational losses of at least $10 million – a total of 403 bank events and 89 insurance company events. The results reveal a strong, statistically significant negative stock price reaction to announcements of operational loss events. On average, the market value response is larger for insurers than for banks. Moreover, the market value loss significantly exceeds the amount of the operational loss reported, implying that such losses convey adverse implications about future cash flows. Losses are proportionately larger for institutions with higher Tobin’s Q ratios, implying that operational loss events are more costly in market value terms for firms with strong growth prospects.     

The macroeconomic determinants of technology stock price volatility

Stock prices reflect the value of anticipated future profits of companies. Since business cycle conditions impact the future profitability of firms, expectations about the business cycle will affect the current value of firms. This paper uses daily and monthly data from July 1986 to December 2000 to investigate the macroeconomic determinants of US technology stock price conditional volatility. Technology share prices are measured using the Pacific Stock Exchange Technology 100 Index. One of the novel features of this paper is to incorporate a link between technology stock price movements and oil price movements. The empirical results indicate that the conditional volatilities of oil prices, the term premium, and the consumer price index each have a significant impact on the conditional volatility of technology stock prices. Conditional volatilities calculated using daily stock return data display more persistence than conditional volatilities calculated using monthly data. These results further our understanding of the interaction between oil prices and technology share prices and should be of use to investors, hedgers, managers, and policymakers.     

风险投资声誉和股价“传染”效应——来自中国上市公司立案公告的证据

本文以我国2007-2015年证监会立案调查事件为样本,研究当风险投资支持的上市公司涉嫌违规,同一风险投资所支持的其他上市公司(即关联公司)的股价是否会被“传染”。实证结果表明,有风投背景的上市公司在立案公告日有显著的负面市场反应(约-8%),并且这种负面反应会通过共同的风险投资链条“传染”给关联公司(约-1.2%)。我们还发现,风险投资机构的声誉越高,风险投资对涉嫌违规企业参与度越高,则立案调查事件对风险投资的声誉损害越严重,市场对关联上市公司的惩罚也越严重。     

The influence of oil prices on the banking sector in oil-exporting economies: Is there a psychological barrier?

This paper examines the relationship between crude oil prices and banking sector market indices in the oil-exporting economies of the Gulf Cooperation Council (GCC), using daily frequency data over 2010–2017. Controlling for global banking impacts (S&P500 Banking Index) and interest rates (T-bills), dynamic ordinary least squared (DOLS) and fully modified ordinary least squared (FM-OLS) analysis indicates that oil prices positively affect bank indices until the $95 per barrel mark, after which the impact becomes negative, close to the psychological barrier found in the US equity market. The S&P500 Banking Index positively affects the GCC banking sector, whereas the interest rate affects it negatively. The validity of an inverse U-shaped relationship between crude oil price and banking sector indices is demonstrated. Causality analysis reveals the existence of bidirectional causalities between the prices of crude oil, GCC banking sectors, and the US banking sector. This paper demonstrates a vital non-linear relationship for oil-banking portfolio management and hedging strategies with oil price risk.     

Barriers to entry to the big firm audit market: Evidence from market reaction to switches to second Tier audit firms in the post-sox period

The US Government Accountability Office (GAO) studied concentration in the audit market and found that the Big 4 firms continue to dominate the market for clients with revenue of more than $500 million while non-Big 4 firms have gained market share among clients with revenue of $500 million or less (GAO, 2008). The US Treasury Advisory Committee on the Auditing Profession has expressed concern about barriers to entry that might prevent a non-Big 4 firm from increasing its market share among large publicly-traded clients (Advisory Committee, 2008). One of these barriers may be the potential cost to shareholders if the stock market reacts negatively to the appointment of a non-Big 4 auditor (GAO, 2003). We examine whether the stock market reacts negatively when clients switch from a Big 4 to a non-Big 4, because a negative reaction might make such switching less likely to occur. We find that the market does not react more negatively when clients move from a Big 4 to a Second Tier auditing firm than when clients move from a Big 4 to another Big 4 firm. Our results suggest that a negative market reaction may not represent a significant barrier to entry among Second Tier auditing firms.     

MicroHoo: Deal failure,industry rivalry,and sources of overbidding

On February 1, 2008, Microsoft offered $43.7 billion for Yahoo. This offer was a milestone in the battle between Microsoft and Google to control the Internet search industry. The announcement accompanied a substantial decrease in Microsoft's stock price. Investors apparently considered the bid too high and doubted Microsoft's ability to create value with Yahoo's assets (the announcement combined returns implied a total value destruction of $13.29 billion). Using the abnormal returns pattern of industry firms and customers, this article examines the sources of overbidding. Our analyses indicate that Microsoft's aggressive move is rooted in its rivalry with Google, but the personality traits of the involved CEOs might explain also a portion of the overbidding.     

The financial impact of COVID-19: Evidence from an event study of global hospitality firms

This paper examines the daily abnormal stock price returns of a sample of 154 publicly-traded hospitality firms from 23 different countries representing over $400 billion in combined market capitalization around the time that COVID-19 was first viewed by stock market participants as a major—possibly even existential—threat. The findings of the study suggest that, financially, hotels performed better than restaurants, which themselves performed better than casinos. These findings are consistent with medical recommendations concerning the relative safety of various hospitality-related activities and, therefore, also with the tenets of financial market efficiency in the hospitality sector. Additional findings suggest that hospitality firms with strong balance sheets and income statements characterized by relatively low leverage ratios, high market value (consistent with a “too big to fail” mentality), and higher price/earnings ratios (implying higher relative profitability) all fared better than smaller, weaker firms. Although, in no case, did Bloomberg's proprietary environmental, social, and governance (ESG) variable possess any predictive power, variables reflecting cross-country cultural differences support Huynh’s (2020) finding that “individualism” was an important factor in explaining the economic impact of the COVID-19 pandemic on hospitality firms.     

Capital raising in the offshore market

US corporations can raise capital in the offshore market using Regulation S, adopted by the Securities and Exchange Commission (SEC) in 1990 and modified in 1996. We examine how offshore offerings are done under Regulation S, what types of companies use this market, the discount companies offer investors to compensate for illiquidity in the market, and the impact of the new disclosure requirements on capital raising in the offshore market. We find that small firms tend to raise capital in this market. During our sample period before the 1996 rule change the median market capitalization of reporting firms was $16.82 million with a median stock price of $1.13. The mean and median discount offered to foreign investors was 32.84% and 40.53%, respectively. Offerings during this period resulted in average share dilution of 11.97%. We find that before the disclosure requirements, firms were “gaming the system” by giving foreign investors just enough time to resell the securities back into the United States before the initial sale became public information. After the rule changes, Regulation S offerings are not perceived to be “shady”, and larger firms are now using the market, resulting in lower average discount and dilution.     

Sell the rumour,buy the fact?

We document a high‐profile instance of mispricing that is puzzling given the gradual information diffusion hypothesis and the lack of obvious limits to arbitrage. An internet search in 2008 led to a story about United Airlines’ 2002 bankruptcy being re‐released as ‘news’. This resulted in United Airlines losing 73 per cent of its value and caused a $4.2 billion decline in the value of airline stocks and United Airlines suppliers. The incorrect bankruptcy ‘news’ was quickly retracted, which led to a rebound in other airline and supplier firms, but the stock price of United Airlines was adversely affected for 4 days.     

Oil prices,US stock return,and the dependence between their quantiles

In this article, we examine the relationship between oil prices and US equities by proposing a novel quantile-on-quantile (QQ) approach to construct estimates of the effect that the quantiles of oil price shocks have on the quantiles of the US stock return. This approach captures the dependence between the distributions of oil price shocks and the US stock return and uncovers two nuance features in the oil–stock relationship. First, large, negative oil price shocks (i.e. low oil price shock quantiles) can affect US equities positively when the US market is performing well (i.e. at high US return quantiles). Second, while negative oil price shocks could affect the US stock market, the influence of positive oil price shocks is weak, which suggests that the relationship between oil prices on the US equities is asymmetric.     

Generalized DEA model of fundamental analysis and its application to portfolio optimization

Fundamental analysis is used in asset selection for equity portfolio management. In this paper, a generalized data envelopment analysis (DEA) model is developed to analyze a firm’s financial statements over time in order to determine a relative financial strength indicator (RFSI) that is predictive of firm’s stock price returns. RFSI is based on maximizing the correlation between the DEA-based score of financial strength and the stock market performance. This maximization involves a difficult binary nonlinear program that requires iterative re-configuration of parameters of financial statements as inputs and outputs. We utilize a two-step heuristic algorithm that combines random sampling and local search optimization. The proposed approach is tested with 230 firms from various US technology-industries to determine optimized RFSI indicators for stock selection. Then, those selected stocks are used within portfolio optimization models to demonstrate the usefulness of the scheme for portfolio risk management.     

地方官员更替、企业辖区知名度与股价同步性

以2009～2013年我国A股上市公司为研究样本,实证分析地方官员更替、辖区企业知名度与股价同步性的关系,结果表明:地市级政府官员变更所带来的政治不确定性会显著降低辖区企业的股价同步性,并且相对于新任官员来源于本地而言,新任官员来源于异地更能够显著地降低辖区内企业的股价同步性.进一步研究还发现,当地市级政府官员发生变更时,相对于辖区知名度较高的企业而言,辖区知名度较低的企业会披露更多的企业私有信息以应对政治不确定性风险,从而其股价同步性有了更大程度的降低.研究的结论证实了政治不确定风险的增加能够显著降低辖区内企业的股价同步性,客观上有助于提高股价的信息含量.     

Risk,Mispricing, and Value Investing

We evaluate the stock return performance of a modified version of the book-to-market strategy and its implications for market efficiency. If the previously documented superior stock return of the book-to-market strategy represents mispricing, its performance should be improved by excluding fairly valued firms with extreme book-to-market ratios. To attain this, we classify stocks as value or glamour on book-to-market ratios and accounting accruals jointly. This joint classification is likely to exclude stocks with extreme book-to-market ratios due to mismeasured accounting book values reflecting limitations underlying the accounting system. Using both 12-month buy-and-hold returns and earnings announcement returns, our results show that this joint classification generates substantially higher portfolio returns in the post-portfolio-formation year than the book-to-market classification alone with no evidence of increased risk. In addition, this superior stock return performance is more pronounced among firms held primarily by small (unsophisticated) investors and followed less closely by market participants (stock price <$10). Finally, and most importantly, financial analysts are overly optimistic (pessimistic) about earnings of glamour (value) stock, and for a subset of firms identified as overvalued by our strategy, the earnings announcement raw return, as well as abnormal return, is negative. These last results are particularly important because it is hard to envision a model consistent with rational investors holding risky stocks with predictable negative raw returns for a long period of time rather than holding fT-bills and with financial analysts systematically overestimating the earnings of these stocks while underestimating earnings of stocks that outperform the stock market.     

LONG-TERM STOCK PRICE REVERSALS IN THE UK: EVIDENCE FROM REGRESSION TESTS

This paper seeks to advance our knowledge about the UK evidence on long-term stock price reversals. Many of the major studies of long-term reversals have been done using US data, prompting fears about data snooping biases. There have been comparatively few UK studies and they have all employed contrarian portfolio techniques to identify evidence of reversals. None of these UK studies has used cross-section regression tests, which have been employed in some of the US investigations, and this paper aims to fill this gap. We find evidence of stock price reversals, even after controlling for time-varying risk and restricting the study to larger, UK-listed companies—that is, companies that are frequently traded, more heavily regulated and extensively analysed by market commentators, analysts and institutional investors.     

A re-examination of the index effect: Gambling on additions to and deletions from the S&P 500's ‘gold seal’

This study examines the abnormal returns, trading activity, volatility and long-term performance of stocks that were added to the S&P 500 index. By using a three-factor pricing model that allows for firm size and value characteristics as well as market risk, we are able to shed new light on the widely observed ‘index effect’. We find that the CAPM tends to overstate the performance of large firms and to understate the performance of small firms. We also find a transitory increase in trading volume between the announcement and a few days after the effective date. In terms of the firm's operating performance, we find a significant increase in earnings per share after inclusion, which combines with the stock price rise to leave the average price-earnings ratio largely unaltered. Examining a unique sample of deletions of international companies and replacements with US companies, we find that deleted stocks experienced a considerable and permanent fall in price, inconsistent with the Investor Recognition Hypothesis. The “seal” of S&P 500 index membership has very long-term effects and inclusion appears not to be an information-free event.     

Stock price behavior surrounding stock repurchase announcements: Evidence from Japan

This paper examines stock price behavior surrounding announcements of stock repurchases made by Japanese firms from 1995 to 1998. Our analysis shows that, much as in the case of the U.S. markets, stock prices in Japan go up in response to stock repurchase announcements. We also find that there is no significant difference between the market reaction to the announcement for intention of repurchase execution and the market reaction to the announcement of an article alteration to allow stock repurchases. On the other hand, there is a significant difference in the pre-announcement period returns motivating these two announcements. While a large decline in stock price will motivate a firm to execute a stock repurchase, a smaller price decline will motivate a firm to merely alter its articles of association to allow future repurchases.
