Do bond rating changes affect the information asymmetry of stock trading?

Using a sample of 279 upgrades and 310 downgrades from 1996 to 2004, we find that bond rating changes affect the information asymmetry of stock trading and other measures of information risk. Specifically, when a firm's bond rating is upgraded, its stock information asymmetry and its analysts' earnings forecast dispersion are significantly reduced, while the institutional equity holdings of its shares are significantly increased. The reverse is true for a downgrade. In addition, the degree of change in stock information asymmetry is positively associated with the magnitude of the bond rating changes.     

Does option trading convey stock price information?

After executing option orders, options market makers turn to the stock market to hedge away the underlying stock exposure. As a result, the stock exposure imbalance in option transactions translates into an imbalance in stock transactions. This paper decomposes the total stock order imbalance into an imbalance induced by option transactions and an imbalance independent of options. The analysis shows that the option-induced imbalance significantly predicts future stock returns in the cross section controlling for the past stock and options returns, but the imbalance independent of options has only a transitory price impact. Further investigation suggests that options order flow contains important information about the underlying stock value.     

Do political connections affect stock price crash risk? Firm-level evidence from China

Using a sample of Chinese listed firms in the period from 2003 to 2012, this paper empirically investigates how the presence of politically connected directors affects stock price crash risk. We thereby make a distinction between listed state-controlled firms and privately controlled firms due to their different incentives to appoint politicians as directors on the board. Our empirical results show that politically connected directors exacerbate stock price crash risk in listed state-controlled firms, an effect driven by the appointment of local government officials as directors. In contrast, hiring politicians as directors, particularly central-government-affiliated directors, helps listed privately controlled firms to reduce stock price crash risk. Finally, good quality of institutions does not help to alleviate the positive relationship between political connections and stock price crash risk in listed state-controlled firms. However, it does weaken the role of political connections in reducing crash risk in listed privately controlled firms.     

Does corporate eco-innovation affect stock price crash risk?

We examine the effect of corporate environmental innovation (hereafter eco-innovation) on stock price crash risk and document a significant negative association. Utilising a large sample of publicly listed U.S. firms for the period 2003 to 2017, we find that an increase in eco-innovation from the 25th to the 75th percentile is associated with 17.62% reduction in stock price crash risk. This outcome remains robust to a variety of sensitivity tests and after accounting for potential endogeneity concerns. Eco-innovative firms attract more institutional investors and equity analyst following and disclose more information leading to lower stock price crash risk. Additional tests reveal that the negative effect of eco-innovation is contingent on the political leadership's ideology and environmental sensitivity. Our paper contributes to the ongoing discourse on the costs and benefits of eco-innovation, documenting the value-enhancing perspective of eco-innovation.     

The information content of stock split announcements: Do options matter?

We provide a new test of the informational efficiency of trading in stock options in the context of stock split announcements. These announcements tend to be associated with positive abnormal returns. Our traditional event study results show abnormal returns that are significantly lower for optioned than non-optioned stocks, whether traded on the NYSE, Amex, or Nasdaq. After controlling for market returns, capitalization, book-to-market ratio, and trading volume, we find that the abnormal returns are significantly lower for NYSE/Amex optioned than non-optioned stocks. Although the results for Nasdaq stocks are not as clear, the overall effects tend to be lower after optioning. These findings are consistent with the hypothesis that the prices of optioned stocks embody more information, diminishing the impact of the stock split announcement. They provide new evidence of the beneficial effects of options on their underlying stocks.     

Do stock bulletin board systems (BBS) contain useful information? A viewpoint of interaction between BBS quality and predicting ability

This study explores whether information on internet stock bulletin board systems (BBS) is valuable for stock return prediction, taking advantage of data derived from the biggest stock BBS in China. Using a text classification algorithm, we find the online messages significantly predict stock return with negligible R‐squared. However, we find that accuracy of individual BBS posts is below 50 percent and there is no distinction at prediction accuracy between high‐ and low‐quality stock BBS. Due to the autocorrelation of stock returns, we argue that BBS predicts stock returns because of its reflection on the simultaneous stock return rather than revelation on valuable information.     

Do the stock and CDS markets price credit risk equally in the long-run?

In this paper, we examine the existence and stability of the long-run equilibrium relation between the price of credit risk in the stock and CDS markets for a sample of non-financial iTraxx Europe companies during the 2004–2017 period. We show that standard cointegration tests with no breaks frequently fail to detect cointegration. Once we formally account for the breaks in the cointegrating vector, we are able to detect cointegration over the entire sample period for the vast majority of the companies considered. An application of these results to CDS-equity trading shows that the profitability of traditional trading strategies crucially depends on the presence of cointegration and on the stability of the cointegrating vector. Finally, we find that CDS illiquidity factors decrease the likelihood of the stock and CDS market cointegration.     

The effect of CEO luck on the informativeness of stock prices: Do lucky CEOs improve stock price informativeness?

CEOs are “lucky” when they are granted stock options on days when the stock price is lowest in the month of the grant, implying opportunistic timing and severe agency problems (Bebchuk et al., 2010). Using idiosyncratic volatility as our measure of stock price informativeness, we find that lucky CEOs improve the informativeness of stock prices significantly. In particular, CEO luck raises the degree of informativeness by 4.39%. Powerful CEOs who can circumvent governance mechanisms and successfully practice opportunistic timing of options grants are so secured in their positions that they have fewer incentives to conceal information, thereby improving informativeness.     

Do political factors affect stock returns during presidential elections?

This study investigates whether or not political factors such as government policy and political connections affected stock returns during the 2008 Taiwanese presidential election. We find that firms that benefitted from (were threatened by) the proposed Three-Links policy of the winning party experienced positive (negative) stock returns during the election. We use the sensitivities of firms’ returns to bilateral trade flows between Taiwan and China to measure the government-policy effect. Our results show that the effects of political connections weakly exist, but they become more significant when the support ratio of the winning party increased in polling data. We also find that only the government-policy effect holds for different crash-risk and corporate-governance levels. Finally, investment strategies based on both political factors can generate positive abnormal returns with respect to the Fama-French Three-factor Model.     

Do asset impairments and the associated disclosures resolve uncertainty about future returns and reduce information asymmetry?

The objective of this study is to provide insights into how Australian listed firms are implementing AASB 136 Impairments of Assets. Our first concern is whether uncertainty about future returns and information asymmetry motivates the recognition of asset impairments. We find no evidence that the recognition of asset impairments is associated with higher uncertainty about future returns. Furthermore, we find no evidence that the recognition of asset impairments is associated with higher information asymmetry. Our second concern is whether asset impairments and the associated disclosures provide information that reduces uncertainty about future returns and information asymmetry. While we find some evidence that asset impairments are associated with decreases in information asymmetry before the financial crisis, during the financial crisis, asset impairments are associated with increases in both measurement uncertainty and information asymmetry.     

Do voluntary disclosures of product and business expansion plans impact analyst coverage and forecasts?

We investigate whether voluntary disclosures of product and business expansion plans affect analyst coverage and forecasts. We find that the level of analyst coverage is positively associated with the incidence of disclosures of product and business expansion plans. We also find that product and business expansion disclosures increase the informativeness of analyst earnings forecasts. We find no evidence that product and business expansion disclosures increase analyst forecast errors. Overall, our study contributes to understanding the role of product and business expansion disclosures in analyst forecast behaviour.     

Do tax decision support systems affect the accuracy of tax compliance decisions?

Tax complexity has increased over the years as laws and regulations have been consistently added to the existing code sections. This complexity directly affects taxpayer compliance; complexity reduces taxpayer compliance. Along with the rise in complexity has come an increased use of tax preparation software such as TurboTax to combat the rising intricacy. This software is designed to help users properly complete a tax return and, as a result, increase taxpayer compliance. These software packages represent sophisticated tax decision support systems (TDSS) used by both professional tax preparers and individual taxpayers alike. While the availability and use has risen dramatically over the past few years, little research has been conducted to determine the impact of TDSS on tax preparers' decisions. The purpose of this study is to examine whether tax preparers manually preparing a tax return make the same decisions as tax preparers aided by a TDSS. The Theory of Technology Dominance suggests (1) that less experienced users will not be able to adequately use the TDSS and will make inferior decisions when compared to more experienced users and (2) that more experienced decision-makers using a TDSS will make better decisions than their counterparts preparing a return manually. The results support the propositions of the theory and show that less experienced tax preparers using a TDSS make inferior decisions when compared to more experienced tax preparers. The less experienced tax preparers report higher taxable income and higher tax liability. The results also indicate that using a TDSS can help both experienced and novice tax preparers make better decisions even though the novices cannot perform at the level of experienced tax preparers. This study concludes tax compliance is improved with the use of a TDSS.     

Does the stock market affect firm investment in China? A price informativeness perspective

This paper investigates the empirical relationship between firm-level investment and the stock market in China from a price informativeness perspective. We find that firm investment does not significantly respond to the stock market valuation, because stock prices contain very little extra information about the future operating performance of firms. This finding is further supported by the relative investment response test and the relative price information content test based on the informativeness proxy of price non-synchronicity combined with firm information transparency.     

Do students’ perceptions matter? A study of the effect of students’ perceptions on academic performance

Prior accounting education literature documents that students typically associate accounting subjects with negative perceptions, but there are also recent suggestions that the stereotype of the accountant has positive associations. These perceptions of accounting are likely to affect students’ attitudes towards learning and, consequently, influence their performance. We examine the relationship between students’ perceptions and students’ performance. The present study involved undergraduate and graduate students enrolled in management accounting subjects. Our findings indicate that students’ performance is negatively affected by the negative perceptions of accounting that students bring to the subject. Our findings also suggest that positive perceptions of accounting held by students at the end of the semester have a positive impact on students’ performance.     

Do monetary policy announcements affect stock prices in emerging market countries? The case of Thailand

We examine the effect of monetary policy announcements in Thailand, which is one of emerging market countries in Asia, on stock prices at the firm level. We find that the expected change, rather than the unexpected change, in interest rates affects stock prices. The stock price response to the interest rate announcement is asymmetric. For instance, the relation between interest rate surprises and stock prices is conditional on the direction of the interest rate change. In general, macroeconomic conditions and firm characteristics cannot explain the stock price reaction to the announcement. In addition, stock prices of firms in different industries appear to react heterogeneously to the interest rate announcement.     

Is there useful information in the ‘use of proceeds’ disclosures in IPO prospectuses?

This study contributes evidence on the valuation relevance of the ‘use of proceeds’ disclosure in the initial public offering (IPO) prospectus. This article develops a classification of ‘use of proceeds’ disclosures that aims to capture information embedded in the disclosures relating to the purpose (growth, production, financing) and amount committed to specific assets. These measures are then related to IPO underpricing, survival prediction and expected and realised prospects of the IPOs. The results suggest the ‘use of proceeds’ disclosure categories have incremental information over other sources of information for underpricing, for predicting firm survival and in the case of some disclosure categories, for investors’ evaluation of the firms’ prospects and risks in the early years after listing.     

Does more information in stock price lead to greater or smaller idiosyncratic return volatility?

We investigate the relation between price informativeness and idiosyncratic return volatility in a multi-asset, multi-period noisy rational expectations equilibrium. We show that the relation between price informativeness and idiosyncratic return volatility is either U-shaped or negative. Using several price informativeness measures, we empirically document a U-shaped relation between price informativeness and idiosyncratic return volatility. Our study therefore reconciles the opposing views in the following two strands of literature: (1) the growing body of research showing that firms with more informative stock prices have greater idiosyncratic return volatility, and (2) the studies arguing that more information in price reduces idiosyncratic return volatility.     

Do foreign investors improve stock price informativeness in emerging equity markets? Evidence from Vietnam

Most of previous studies on stock price informativeness tend to focus on the context of mature stock markets while this issue is more acute in emerging equity markets where regulatory and institutional structure are weak. This paper examines the relationship between foreign ownership and stock price informativeness in Vietnam stock market. We utilize a data set covering firm attributes of non-financial firms listed on the Ho Chi Minh City stock exchange over the period 2007–2015. Employing different estimation techniques for panel data, the empirical results indicate that foreign investors improve stock price informativeness in Vietnam stock market. The finding from this paper confirms the important role of foreign investors in emerging equity markets.     

Understanding investors’ reliance on disclosures of nonfinancial information and mitigating mechanisms for underreliance

This study uses two experiments to examine whether nonprofessional investors rely on voluntarily disclosed nonfinancial information (NFI) and the factors that affect their reliance on such information. Results from experiment one suggest that nonfinancial disclosure affects high-experience (long-term) investors more than low-experience (short-term) investors. In addition, more investing experience seems to compensate the insensitivity to NFI caused by a short-term investment horizon. Results from experiment two suggest that merely requiring participants to evaluate firms’ performance separately based on the financial and nonfinancial measures (NFMs) – or merely presenting the NFMs in a more readable format – does not significantly alter the reliance on the nonfinancial disclosure for low-experience and short-term investors. However, when the two interventions are implemented simultaneously, NFI significantly affects the amount invested by those investors.
