Stock price synchronicity and analyst coverage in emerging markets

This paper examines the relation between the stock price synchronicity and analyst activity in emerging markets. Contrary to the conventional wisdom that security analysts specialize in the production of firm-specific information, we find that securities which are covered by more analysts incorporate greater (lesser) market-wide (firm-specific) information. Using the R² statistics of the market model as a measure of synchronicity of stock price movement, we find that greater analyst coverage increases stock price synchronicity. Furthermore, after controlling for the influence of firm size on the lead–lag relation, we find that the returns of high analyst-following portfolio lead returns of low analyst-following portfolio more than vice versa. We also find that the aggregate change in the earnings forecasts in a high analyst-following portfolio affects the aggregate returns of the portfolio itself as well as those of the low analyst-following portfolio, whereas the aggregate change in the earnings forecasts of the low analyst-following portfolio have no predictive ability. Finally, when the forecast dispersion is high, the effect of analyst coverage on stock price synchronicity is reduced.     

Opaque financial reports, R, and crash risk

We investigate the relation between the transparency of financial statements and the distribution of stock returns. Using earnings management as a measure of opacity, we find that opacity is associated with higher R²s, indicating less revelation of firm-specific information. Moreover, opaque firms are more prone to stock price crashes, consistent with the prediction of the Jin and Myers [2006. R² around the world: new theory and new tests. Journal of Financial Economics 79, 257–292] model. However, these relations seem to have dissipated since the passage of the Sarbanes-Oxley Act, suggesting that earnings management has decreased or that firms can hide less information in the new regulatory environment.     

Capital market governance: How do security laws affect market performance?

This paper examines the link between capital market governance (CMG) and several key measures of market performance. Using detailed data from individual stock exchanges, we develop a composite CMG index that captures three dimensions of security laws: the degree of earnings opacity, the enforcement of insider laws, and the effect of removing short-selling restrictions. We find that improvements in the CMG index are associated with decreases in the cost-of-equity capital (both implied and realized), increases in market liquidity (trading volume, market depth, and U.S. foreign investments), and increases in market pricing efficiency (reduced price synchronicity and IPO underpricing). The results are quite consistent across individual components of CMG and over alternative market performance measures.     

Rumors in the sky: Corporate rumors and stock price synchronicity

Using hand-collected rumor clarification announcements from Chinese listed firms to identify corporate rumors, we find that rumored firms have lower stock price synchronicity (R²) than do firms without rumors. Channel analyses reveal that rumors reduce stock price synchronicity through elevating investor sentiment rather than stimulating informed trading. Additionally, the negative association between corporate rumors and stock price synchronicity is more evident among firms with more individual investors and higher information opacity. Moreover, corporate rumors are associated with higher analyst forecast errors and forecast dispersion. Overall, our evidence suggests that corporate rumors reduce stock price synchronicity by increasing investor irrationality.     

Difference of opinion and the cross-section of equity returns: Australian evidence

This paper examines the relationship between difference of opinion among investors and the return on Australian equities. The paper is the first to employ dispersion in analysts' earnings forecasts, abnormal turnover and idiosyncratic volatility as proxies for difference of opinion. We document a negative relationship between difference of opinion and stock returns when dispersion in analysts' forecasts and idiosyncratic volatility are employed as proxies. This result provides support for Miller's (1977) model and is consistent with the findings of Diether et al. (2002). In contrast, we find mixed results when using abnormal turnover to proxy difference of opinion.     

Discussion of “Are earnings forecasts more accurate when accompanied by cash flow forecasts?”

Call et al. (Rev Account Stud 2009, this issue) demonstrate that, relative to analysts who issue earnings but not cash flow forecasts, analysts who issue both forecasts (i) produce relatively more accurate earnings forecasts, (ii) have a better understanding of the persistence of current earnings, and (iii) are less likely to get fired. In my discussion, I highlight some general challenges facing research on analyst cash flow forecasts, demonstrate the diminishing difference in the relative accuracy over time (including its compete elimination by 2004), and examine the sensitivity of some of the evidence in Call et al. (2009) to the age of the forecast and to the presence of extreme bad-news earnings surprises.     

Do star analysts know more firm-specific information? Evidence from China

Using a unique database in China, we extend the literature to further distinguish the information production role of star vs. non-star analysts. We confirm the general conclusion of a positive association between analyst coverage and stock return synchronicity measured by a firm’s R² in China. The findings from star analysts, however, show that star analyst coverage actually decreases stock return synchronicity. We contend that the firm-specific human capital in star analysts helps the analysts overcome the challenges of information production in an emerging market. The superior firm-specific human capital argument of star analysts is further supported by the negative association of star analysts’ firm-specific experiences and stock return synchronicity. Our conclusions are robust to different specifications of star analyst presence and different definitions of analysts’ firm-specific experiences. We also find that star analysts exhibit a more accurate earnings forecast than non-star analysts.     

Are short sellers incrementally informed prior to earnings announcements?

Contrary to the hypothesis that informed short sellers increase their positions prior to earnings announcements, we find that short activity declines in the pre-announcement period compared with activity in non-announcement time. This statistically significant, but economically modest, decline may suggest that the fraction of informed short sellers actually increases if (as Diamond and Verrecchia (1987) suggest) the uncertainty around earnings announcements increases short selling costs and causes uninformed short sellers to withdraw from the market. While we find a statistically and economically significant inverse relation between pre-announcement short activity and announcement period returns, when we control for the non-announcement ability of short sellers to predict future returns documented by Diether et al. (2009), the significance of the relation between pre-announcement short activity and announcement period returns vanishes. Thus, we infer that short sellers are not incrementally informed prior to earnings announcements.     

Discussion of “Implications of the integral approach and earnings management for alternative annual reporting periods”

The paper by Gunny, Jacob, and Jorgensen (Rev Account Stud, 2013) provides evidence on whether the earnings volatility induced by year-end adjusting entries results from the integral method of accounting or from purposeful earnings management. The authors find that the variance and negative skewness of annual fiscal-year earnings is greater than the corresponding attributes of alternative annual earnings ending in the first three quarters and interpret these findings as evidence consistent with earnings management rather than settling up annual earnings under the integral method of accounting. While it is difficult to assess the usefulness of their conclusion due to problematic assumptions inherent in the research design, Gunny et al. (2013) reinforce the importance of assessing earnings performance using rolling annual windows. Specifically, they find that the quality of earnings for the alternative annual earnings is greater than that of fiscal-year earnings, highlighting that financial statement users may benefit from using alternative annual earnings to assess current and future performance.     

External Conditions,the Evolution of Financial Risks,and the Informational Content of Stock Prices: The Case of Chile

ABSTRACT

In this article, we find that the dynamics of local financial risks in the Chilean stock market are associated with the evolution of external economic conditions, with a strong reduction in both idiosyncratic and systematic risks during periods of stable conditions. Despite this, we fail to find any significant change in the traditional measures of stock price synchronicity developed in the R² literature in our sample. We argue that these measures neglect the relationship between stock prices and fundamentals and find that the strength of the association between prices and fundamentals changes during our sample period, being much stronger during times of stable external conditions and diminished stock price volatility.     

新会计准则、会计信息质量与股价同步性

本文以2004—2008年我国A股上市公司为样本,基于私有信息交易理论,分析会计信息质量如何影响股价同步性,以及新会计准则的改革如何影响了两者之间的相关性。结果发现,会计信息质量与股价同步性正相关,并且这种正相关性仅存在于负向盈余管理的情况,而在正向盈余管理的情况中两者之间的正相关性不明显,这与我国股票市场的卖空限制有关。同时,2007年新会计准则质量的提高显著减弱了会计信息质量与股价同步性之间的正相关关系。本文不但丰富了会计信息质量和股价同步性的相关文献,而且对我国资本市场加强会计准则改革和会计信息监管具有一定的参考价值。     

Financial distress and idiosyncratic volatility: An empirical investigation

We investigate the link between distress and idiosyncratic volatility. Specifically, we examine the twin puzzles of anomalously low returns for high idiosyncratic volatility stocks and high distress risk stocks, documented by Ang et al. (2006) and Campbell et al. (2008), respectively. We document that these puzzles are empirically connected, and can be explained by a simple, theoretical, single-beta CAPM model.     

Idiosyncratic risk and the cross-section of expected stock returns

Theories such as Merton [1987. A simple model of capital market equilibrium with incomplete information. Journal of Finance 42, 483–510] predict a positive relation between idiosyncratic risk and expected return when investors do not diversify their portfolio. Ang, Hodrick, Xing, and Zhang [2006. The cross-section of volatility and expected returns. Journal of Finance 61, 259–299], however, find that monthly stock returns are negatively related to the one-month lagged idiosyncratic volatilities. I show that idiosyncratic volatilities are time-varying and thus, their findings should not be used to imply the relation between idiosyncratic risk and expected return. Using the exponential GARCH models to estimate expected idiosyncratic volatilities, I find a significantly positive relation between the estimated conditional idiosyncratic volatilities and expected returns. Further evidence suggests that Ang et al.'s findings are largely explained by the return reversal of a subset of small stocks with high idiosyncratic volatilities.     

Shadows in the Sun: Crash risk behind Earnings Transparency

Prior studies suggest that earnings and non-earnings information can be complementary to each other (Lundholm, 1988). Given the co-existence of both components, a lack of non-earnings information can end up boosting earnings explanatory power on returns in certain circumstances, producing spuriously high earnings transparency (ET) in Barth et al. (2013). This scenario is plausible when insiders are motivated to exploit their information advantage and discretionarily alter non-mandatory disclosure strategy. Conditional on higher insider trading profit, we uncover a positive relation between the firm-specific earnings transparency and crash risk. In addition, the above relation is more pronounced with respect to selling and profitable insider transactions. Overall, we demonstrate a potential dark side of high earnings explanatory power on stock returns, conditional on higher likelihood of non-earnings information hoarding.     

Financial derivatives,opacity, and crash risk: Evidence from large US banks

We test how the use of financial derivatives affects banks’ informational structure and future stock performance based on a sample of large bank holding companies in the US. Using banks’ use of financial derivatives as a proxy for opacity, we find that high level use of interest rate and foreign exchange derivatives are associated with an increase in the synchronicity (R²) of stock price movements with the market index, which indicates less revelation of bank-specific information to the market. This finding is consistent with the prediction of the model developed by Wagner (2007). We document that superior corporate governance tempers these effects. Finally, we find that an increase in the opacity is significantly and positively related to an increase in banks’ future stock price crash risk.     

Return windows and the value relevance of earnings

Research on the value relevance of annual earnings commonly accumulate stock returns over a 12-month period starting from the fourth month of the fiscal year, resulting in a mismatch between the return window and the earnings period (i.e. the fiscal year). By comparing this return window with alternative windows, we show that the mismatch produces a downward bias in the estimated R² from the regression of stock returns on earnings, especially for firms that announce earnings early. Our results also show that both profits and losses are more value relevant when announced earlier, supporting regulatory calls for timely disclosure.     

Discretionary Loan Loss Provisions and Systemic Risk in the Banking Industry

This study examines the relation between earnings management through discretionary loan loss provisions (LLPs) and systemic risk in the U. S. banking sector using a large sample of commercial banks from 1996 to 2009. We find that earnings management increases a bank's contribution to systemic crash risk and systemic distress risk, consistent with the notion that earnings management increases information opacity, facilitates bad news hoarding, co‐moves with macroeconomic conditions, and exhibits cross‐sectional correlation and herding in earnings management. However, the effect of earnings management through discretionary LLPs on systemic risk disappears during the crisis period, consistent with weakened earnings management in crisis times. We also find that the same effect strengthens with bank uncertainty and homogenous loans, and weakens in the post‐SOX period, and when banks are audited by Big 4 auditors.     

Accounting diversity and firm valuation

We examine accounting numbers and stock prices across three countries: Germany, Norway, and the United Kingdom (UK). The accounting systems in the three countries differ in faithfulness to clean surplus accounting and in conservatism. We address three questions. First, are there systematic differences across countries in the value relevance of accounting? Second, are there systematic differences in the incremental and relative value relevance of book values and earnings per shape (EPS) across the countries? Third, do future earnings realizations (proxies for expected earnings) explain current stock prices? We find that accounting book value and EPS are significantly related to current stock prices across all three countries. German accounting numbers have the lowest relation with stock prices (R² ≈ 40%) and UK accounting numbers the highest (R² ≈ 70%), while Norwegian accounting numbers are in between (R² ≈ 60%). Second, the incremental and relative explanatory power of book value and of EPS differs across time and across countries. Book values explain more than earnings in Germany and Norway, but less in the UK. Finally, future income realization explain little about market prices not already explained by current book value and EPS.     

The effect of alternative goals on earnings management studies: An earnings benchmark examination

Firms’ management manages earnings because they have incentives or goals to do so. Earnings management studies have to account for these different goals as tests of earnings management can be compromised by the effect of conflicting goals. I illustrate this in the setting of Dechow et al. (2003). Their study examines whether firms with small profits and firms with small losses (loss-avoidance benchmark) have differing levels of discretionary accruals. Dechow et al. (2003) find that firms just above the loss-avoidance benchmark do not have discretionary accruals that are significantly different than firms just below the benchmark. However, they do not consider firms just below the loss-avoidance benchmark that might be using discretionary accruals to avoid missing an alternative benchmark. I find that after I consider these alternate earnings benchmark goals, firms just above the benchmark have significantly higher discretionary accruals. This provides direct evidence that the ‘kink’ in the distribution of earnings arises from earnings management. I find similar results for the earnings changes benchmark. These findings highlight the need to consider alternative earnings benchmark goals when examining firms immediately around benchmarks.     

Bank business models,failure risk and earnings opacity: A short- versus long-term perspective

Despite the ongoing bank regulatory reforms, relatively little research attention has been given to the effects of bank business models and opacity of bank balance sheet structure which may hinder regulation and market discipline. In this study, we explore the effects of business model strategies on banks' earnings opacity in the UK banking sector. Distinguishing between the short-term (within) and long-term (between) effects, our findings suggest that retail-oriented business models reduce the likelihood of earnings management practices in the short term but not over the long term. In contrast, wholesale-oriented business models increase the probability of earnings manipulation both in the short and long term. While bank business models characterised by a greater degree of functional diversification tend to lower earnings manipulation in the short term, the long-term incentives cannot be mitigated. Our findings also demonstrate that low failure risk (or greater solvency) represents an important channel in mitigating the effects of business models on earnings management practices both in the short and long term. Our results are robust to alternative proxies for earnings management and failure risk, and the use of alternative methods.
