Determinants of equity return correlations: a case study of the Amman Stock Exchange

This paper seeks to explain time-varying correlations among equity returns. The literature has shown that fundamental and economic factors can explain stock returns or the volatility of markets. Here, panel data analysis is employed to examine whether these factors can also explain the comovement of stock returns. Time-varying correlations among sectoral indexes are estimated using a restricted multivariate threshold GARCH model with dynamic conditional correlation controlling for the asymmetric effects of news and the influence of financial crises. The empirical results from this panel data analysis show that equity return correlations can be explained not only by macroeconomic variables but also by fundamentals within an industry.     

Do Thai stock prices deviate from fundamental values?

The stock market in Thailand experienced several apparent boom and bust cycles in recent years, which raises the question of whether equity prices in Thailand reflect their fundamental values. This paper examines whether the Thai equity market was characterized by rational expectations bubbles over the sample period from June 1975 to June 2006. The cointegration test provides evidence of no long-run relationship among prices, dividends and earnings, indicating the presence of a rational bubble. The results are confirmed by the non-parametric duration dependence test, which shows evidence of negative duration dependence in runs of positive returns, consistent with the presence of rational expectations bubbles. Further analysis reveals departures from fundamental values in the initial sample subperiod ending with the Asian financial crisis in 1997. However, prices appear to be in line with fundamentals in the more recent post-1997 subperiod.     

Equity prices and fundamentals: a DDM–APT mixed approach

This paper focuses on the linkage between equity prices and fundamentals for 27 individual shares belonging to the French stock price index (CAC40). To assess fundamental value, the traditional dividend discount model (DDM) is coupled with the arbitrage pricing theory (APT), which assumes that investors hold efficient portfolios. This yields a simple equity valuation relationship for which the APT determines the long-term risk premium included in the DDM. Accordingly, equity risk premia are determined by common factors reflecting the non diversifiable risk. These factors are not a priori identified by the theory, and therefore must be exhibited through an empirical analysis. Four domestic and three international common factors are found, all being among those identified by empirical analyses of the APT in the literature. While studies related to stock price indices showed that DDM fundamental values are very smooth compared to stock indices, our DDM–APT model reproduces both trends and major fluctuations of share prices. Further, as for studies based on stock indices, a mean-reverting process of equity prices towards fundamentals is highlighted, but the linear error correction model that was considered contains shortcomings suggesting a more complex adjustment process.     

Economic determinants of price informativeness about future earnings

This study investigates how the value-creation process affects the extent to which stock prices incorporate value-relevant information about future earnings. In contrast to previous studies focusing on the value-reporting process, this paper shows that strong product market power accelerates the incorporation of future earnings into current equity prices due to less uncertainty about future cash flows and that intensive long-term investment deters such incorporation because of greater uncertainty regarding future cash flows. The results suggest that firm fundamentals shaped by product market competition and long-term investment explain the price informativeness about future earnings beyond the impact of management’s reporting discretion.     

On the systematic volatility of unpriced earnings

Some important puzzles in macro finance can be resolved in a model featuring systematically varying volatility of unpriced shocks to firms? earnings. In the data, the correlation between corporate debt and stock market valuations is low. The model accounts for this via the opposing effect of unpriced earnings risk on levered debt and equity prices. The model also explains the low (or nonexistent) risk-reward relation for the market portfolio of levered equity via the opposing effects of unpriced and priced uncertainty (both components of stock volatility) on the levered equity risk premium. Versions of the model calibrated to empirical measures of both types of fundamental risk can quantitatively substantiate these explanations. Variation in residual earning dispersion accounts for a significant fraction of observed disagreement between debt and equity valuations and of realized stock volatility. The implication that the two components of risk should forecast the levered equity risk premium with opposite signs is also supported in the data. The results are a notable advance for risk-based asset pricing.     

More than words: Can tone of consumer product reviews help predict firms’ fundamentals?

Although financial market participants are increasingly interested in the financial value of unstructured qualitative information regarding the prospects of a firm, empirical evidence remains sparse on the properties of qualitative content in consumer product reviews and their capital market implications. Using a broad sample of consumer reviews posted on Amazon.com, I examine whether the linguistic tone of aggregate consumer product reviews conveys information that is associated with firms’ sales, earnings, stock returns and risk. I find that aggregate review tone successfully predicts a firm's forthcoming quarterly sales. Moderating analyses show that this predictability is stronger for firms operating in a highly competitive environment. I further find that review tone predicts a firm's quarterly earnings surprises, abnormal stock returns and risk. A path analysis shows that the effect of review tone on stock prices is partially channeled through its effect on firms’ earnings. I finally find that negative review tone is more informative and useful than positive tone in predicting a firm's fundamentals. Importantly, these results hold after controlling for other review characteristics, including review rating, review volumeand review dispersion. Overall, my findings highlight the importance of considering the tone of consumer reviews when evaluating a firm's prospects and value.     

Relative valuation of U.S. insurance companies

This study examines the accuracy of relative valuation methods in the U.S. insurance industry, using price as a proxy for intrinsic value. The approaches differ in terms of the fundamentals used, the adjustments made to the fundamentals, the use of conditioning variables, and the selection of comparables. Selected findings include the following. First, over the last decade, book value multiples have performed significantly better than earnings multiples in valuing insurance companies. Second, inconsistent with the practice of many analysts, excluding accumulated other comprehensive income from book value worsens rather than improves valuation accuracy. Third, as expected, using income before special items, instead of reported income, improves valuation accuracy, but, surprisingly, excluding realized investment gains and losses does not. An exception to this latter result occurred during the financial crisis, likely due to an increase in “gains trading.” Fourth, conditioning the price-to-book ratio on return on equity significantly improves the valuation accuracy of book value multiples. Finally, while valuations based on analysts’ earnings forecasts outperform those based on reported earnings or book value, the gap between the valuation performance of forecasted EPS and the conditional price-to-book approach was relatively small during the last decade.     

Terrorism activities and long-term annual management forecasts

We study the effects of terrorist attacks on firms’ long-term annual management earnings forecasts bias. We find that the managers of firms located closer to the epicenters of attacks are more likely to issue optimistic long-term annual earnings forecasts relative to the managers of a control group of unaffected firms. The exposure effect is stronger for more severe terrorist events, and firms with more uncertain fundamentals and less geographic diversification. In addition, we document that managers’ forecast optimism intensifies for firms with stronger negative stock market reaction to the terrorist event, for CEOs with higher ability and for companies that are more likely to issue equity or engage in acquisitions following the terrorist event. Overall, our results are consistent with the idea that long-term annual earnings forecasts are used by managers to counterbalance the short-term pessimistic response to terrorist attacks.     

Using Forecasts of Earnings to Simultaneously Estimate Growth and the Rate of Return on Equity Investment

We develop a method for simultaneously estimating the cost of equity capital and the growth in residual earnings that are implied by current stock prices, current book value of equity, and short-term forecasts of accounting earnings. We demonstrate the use of our method by calculating the expected equity risk premium. Our estimate is higher than estimates in extant studies that are based on the same earnings forecast data. The main difference between our study and these papers is that while they provide arguments supporting an assumed rate of growth beyond the forecast horizon, we estimate this rate.     

不同收益水平上盈余信息与股利政策的交互关系研究

以沪深上市公司为样本,检验盈余信息和股利政策在不同收益上的解释作用,并深入研究盈余信息分别与现金股利、股票股利和多种分配方案等三个层面的股利政策的交互关系。结果表明:在大多数收益水平上,盈余信息和股利政策显著影响市场收益水平,而且二者之间存在显著的交互关系。具体而言,现金股利变化与盈余变化在不同收益水平上具有不同的交互影响;而股票股利与盈余信息的交互影响在各收益水平上均不十分突出;多种分配方案中的"综合政策"与盈余变动在各收益水平上表现出较大的正向交互影响。     

Information diffusion of upstream and downstream industry-wide earnings surprises and its implications

This study presents new evidence that industry-wide earnings surprises diffuse gradually across the supply chain at both industry and individual-firm levels. This evidence provides fundamental support for studies in the literature of gradual information diffusion, commonly using lagged returns as a proxy for information. To allow for the possibility that firms react differently to the industry-wide earnings surprises, this study measures how a stock’s returns respond to the part of its main customer or supplier industry’s lagged returns that are associated with earnings surprises. A long/short equity strategy that combines the firm’s response coefficient and the prior month’s main customer/supplier industry return is shown to be profitable. The strategy tends to select medium-sized firms across industries. Firms in the winner portfolio are more likely to have a positive earning response coefficient and to be less capital intensive and financially constrained. Winners also experience positive responses to both positive and negative shocks while losers experience negative responses to both types of shocks.     

Earnings management and long-run stock performance following private equity placements

We investigate whether the documented earnings management preceding public equity offerings applies to private placements of equity. We also investigate whether earnings management can help explain long-run stock performance following private placements. Our main findings are: (1) little evidence of upward earnings management around private equity placements, and (2) little predictive power of abnormal accruals for long-run stock performance following private equity placements. These results suggest that earnings management is not responsible for post-offering underperformance, if any, for firms issuing equity privately. Our results are robust to two alternative measures of earnings management and three measures of abnormal returns estimated over two sample periods.     

Stock market response to analysts' perceptions and earnings in a technology-intensive environment

This paper investigates the contemporaneous stock market response to financial analysts' perceptions of the firm and accounting earnings in the telecommunication and electronics industry in Finland. Analysts' perceptions used in the study are based on the Most Admired Companies survey similar to that conducted by Fortune magazine in the United States. The results indicate the nonfinancial information of the firm measured in terms of the analysts' perceptions has value relevance in a technology-oriented stock market.     

The Effect of Earnings Management on the Value Relevance of Accounting Information

This study investigates whether opportunistic earnings management affects the value relevance of net income and book value in determining stock price. We document a decrease in the value relevance of earnings in the year of an equity offering for a group of firms with ex post evidence of earnings management. This decrease is greater for the discretionary component of earnings than for the non‐discretionary component. These results are robust to model specification and the type of offering. However, the results are sensitive to firms' disclosure activity prior to the offering.     

Earnings management,market discounts and the performance of private equity placements

Private equity placement data allow us to determine whether sophisticated investors can uncover the true value of firms. This can be done by defining sophisticated investors as those who meet the stringent participation requirements of the private equity market. Our results show private equity issuing firms overstate their earnings in the quarter preceding private equity placement announcements and that sophisticated investors do not ask for a fair discount when purchasing the shares of the private issuing firms. We also find evidence showing that the reversal of the effects of pre-issue earnings management is a significant determinant of the long-term performance of private issues. Results further show that post-issue stock performance and operating performance of firms using “aggressive” earnings management significantly underperform those using more “conservative” earnings management.     

Equity Valuation Using Multiples

We examine the valuation performance of a comprehensive list of value drivers and find that multiples derived from forward earnings explain stock prices remarkably well: pricing errors are within 15 percent of stock prices for about half our sample. In terms of relative performance, the following general rankings are observed consistently each year: forward earnings measures are followed by historical earnings measures, cash flow measures and book value of equity are tied for third, and sales performs the worst. Curiously, performance declines when we consider more complex measures of intrinsic value based on short-cut residual income models. Contrary to the popular view that different industries have different "best" multiples, these overall rankings are observed consistently for almost all industries examined. Since we require analysts' earnings and growth forecasts and positive values for all measures, our results may not be representative of the many firm-years excluded from our sample.     

Value relevance of international accounting standards harmonization: Evidence from A- and B-share markets in China

Applying both the price-levels model and the lagged-price-deflated returns model, we investigated the incremental value relevance of the reconciliation of accounts from the Chinese Accounting Standards (CAS) to the International Accounting Standards (IAS) by those Chinese listed companies that have simultaneously issued A-shares and B-shares. In addition, we examined the usefulness of accounting numbers (earnings and book values) and their value relevance to the A- and B-share markets in China. The study finds that earnings and book values of owners’ equity determined under CAS are more relevant accounting information for the purpose of determining the prices of A- and B-shares. The CAS-based earnings changes were reflected in stock returns in the B-share market, while the CAS-based earnings were closely associated with stock returns in the A-share market. However, the study found that the reconciliation of earnings and book values from CAS to IAS basis is partially value-relevant, mainly to stock prices in the B-share market, while the earnings reconciliation is generally not value-added to stock returns in either the A- or the B-share market. The study results suggest that accounting numbers based on domestic accounting standards, in contrast to IAS, are more value-relevant in the Chinese stock market at present.     

Conservatism, Growth and the Role of Accounting Numbers in the Fundamental Analysis Process

I evaluate the effects of conservative accounting for research and development (R&D) and past growth in R&D on: (1) the relation between aggregate earnings (deflated by price) and contemporaneous stock return, and (2) the association between estimates of value derived from the residual income valuation model (i.e., RIV estimates) and equity market value. I show that the conservative treatment of R&D affects the earnings/return relation only for firms that experience high growth in R&D during the return interval of interest. I also demonstrate that the effect of conservative accounting for R&D on the association between RIV estimates and equity market values is increasing in past growth in R&D.This revised version was published online in August 2005 with a corrected cover date.     

Developing countries converging with developed-country accounting standards: Evidence from South Africa and Mexico

I examine the usefulness (relevance and timeliness) of earnings announcements in two emerging markets, the Johannesburg Stock Exchange (JSE) and the Bolsa Mexicana de Valores Stock Exchange (BMV). A weighted least-squares regression is used to test the association of book values of earnings and equity with firm market value. I find that, on JSE and BMV, earnings and/or book value of equity are value relevant in explaining stock prices. I also find that this association is greater in 2000 as compared to 1998 on the BMV. Regarding timeliness, I find that earnings announcements are accompanied by unusually different returns on JSE, but not on BMV. Market infrastructure, specifically insider-trading rules, may explain BMV results. I suggest that accounting and market infrastructure interact and that such interaction is valuable input to the Financial Accounting Standards Board (FASB) and International Accounting Standards Board (IASB) in their deliberations regarding one set of accounting regulations for all countries.
