Discussion of “Aggregate Margin Debt and the Divergence of Price from Accounting Fundamentals”

Burger and Curtis (2017) is an empirical investigation of whether aggregate margin debt correlates with aggregate stock prices and aggregate accounting‐based fundamentals. While the paper convincingly documents a significant relation: aggregate margin debt is higher when aggregate fundamentals‐to‐price ratios are low, it fails to document why. The documented relation could exist because margin traders are the overly exuberant noise traders that push stock prices higher away from fundamental values; or the documented relation could be spurious, and exist because aggregate margin debt rises with aggregate price levels simply because margin loan capacity increases as aggregate price levels increase. With insufficiently granular data (aggregate margin debt measured monthly), the authors are not able to sort out why the relation exists. Thus, interpretation of the findings documented in this paper is difficult.     

High‐Frequency Contagion of Currency Crises in Asia*

Using daily data from the Asian currency crisis, the present paper examines high‐frequency contagion effects among six Asian countries. The ‘origin’ (of exchange rate depreciation, or decline in stock prices) and the ‘affected’ (currencies, or stock prices) in the daily spillover relationship were defined and identified. Indonesia is found to be the main origin country, affecting exchange rates of other countries. Contrary to conventional wisdom, evidence of high‐frequency crisis spillover from the Thai exchange rate to other currencies was weak at best. There exists a high‐frequency contagion in stock markets among East Asian countries. Contagion coefficients are positively correlated with trade indices, indicating that investors lower their financial assessment of a country that has trade linkage to a crisis origin country within days, if not hours, of a shock.     

A Markov‐switching analysis of Nigeria's business cycles: Are election cycles important?

The study examines Nigeria's business cycles between October 1998 and October 2017 and ascertains the importance of general elections cycles in engendering cyclical fluctuations in different measures of business cycles. A framework based on political business cycles theory was estimated with a dynamic Markov‐switching regression technique. The study finds that election cycles are adequate in predicting cycles in food prices, non‐farm prices, exports, and imports in Nigeria while a significant effect of election cycles on the stock market, general price level, and exchange rate could not be established. The study concludes that cycles in food, non‐farm prices, imports, and exports can be predicted by future general elections while re‐election seeking behaviour of politicians lacks the power to influence stock market performance and exchange rate in Nigeria. Hence, artificial business cycles that result primarily from politicians manipulating certain fiscal tools targeted at stimulating the economy only to increase the re‐election chances could be minimized if monetary and fiscal institutions are strong, effective, and truly independent. This will ensure that policies are not manipulated between elections by politicians but are well targeted at achieving a set of long‐term developmental goals.     

The Persistence of Dominant‐Firm Market Share: Raising Rivals' Cost on the New York Stock Exchange

To explain the persistence of dominant New York Stock Exchange (NYSE) market share in stock trading of listed securities from 1992 to 2002, we develop a dominant‐firm price leadership model and hypothesize that NYSE specialists raised the costs of rival market makers. The model predicts that natural and induced cost advantages will determine the NYSE's market share vis‐à‐vis the regional exchanges, electronic trading systems, and NASDAQ dealers. Empirically, NYSE market share increases with economies of scale and scope, abnormal price volatility, high asymmetric information, and with trading practices that raise rivals' costs, such as failure to display limit orders that bettered the existing quotes.     

Accounting Quality,Stock Price Delay,and Future Stock Returns*

In frictionless capital markets with complete information and rational investors, stock prices adjust to new information instantaneously and completely. However, a substantial body of research studies information imperfections such as asymmetric information and incomplete information. Information imperfections potentially hinder timely price discovery and are likely associated with delayed stock price adjustment to information. Our first research question therefore is whether the quality of accounting information (or “accounting quality”) is one such information imperfection that is associated with cross‐sectional variation in stock price delay. We define accounting quality as the precision with which financial reports convey information to equity investors about the firm’s expected cash flows. Poor accounting quality is likely associated with higher expected returns through uncertainty about stock valuation parameters and incomplete information. Our second research question therefore is whether the accounting quality component of price delay is associated with higher future stock returns. Consistent with our hypotheses, the results show that poor accounting quality is associated with delayed price adjustment and higher future stock returns. Thus, accounting quality plays a role in timely stock price discovery.     

Relating Product Prices to Long‐Run Marginal Cost: Evidence from Solar Photovoltaic Modules

A basic tenet of microeconomics is that for a competitive industry in equilibrium the market price of a product will be equal to its marginal cost. This paper develops a model framework and a corresponding empirical inference procedure for estimating long‐run marginal cost in industries where production costs decline over time. In the context of the solar photovoltaic (PV) module industry, we rely primarily on firm‐level financial accounting data to estimate the long‐run marginal cost of PV modules for the years 2008–2013. During those years, the industry experienced both unprecedented price declines and significant expansions of manufacturing capacity. We compare the trajectory of average sales prices with the estimated long‐run marginal costs in order to quantify the extent to which actual price declines were attributable to reductions in production costs. The trajectory of estimated product costs is then extrapolated to forecast an equilibrium trend line for future PV module prices.     

Gerschenkron Redux? Analysing New Evidence on Joint‐Stock Enterprise in Pre‐War Shanghai

Alexander Gerschenkron (1904–78) famously postulated that the more backward an economy was at the outset of industrialisation, the more reliant it would be on state‐backed banks as a means of directing investment. Gerschenkron thereby implied that impersonal equity markets were likely to play a less significant role in countries aiming to catch up with the West. This article is aimed at examining Gerschenkron's thesis primarily through an analysis of shareholding in 1930s Shanghai. Drawing on newly discovered archival material as well as on recent studies, the paper clarifies the magnitude of joint‐stock enterprise and the ubiquity of stock‐exchange trade in a city that was by far China's most important economic hub. The pattern of joint‐stock enterprise in pre‐war China is compared with that of Japan, the first non‐Western society to become fully industrialised. The argument advanced is that Gerschenkron's thesis incorrectly played down the significance of impersonal equity markets to pre‐war Japan's successful industrialisation and to the limited nature of pre‐war China's industrialisation. Japan could sustain its industrialisation thrust in the early 20th century on a nation‐wide scale partly because of the growing vitality of its equity markets in Tokyo and Osaka. By contrast, China's pre‐war industrialisation was much less extensive because its equity markets were more limited.     

A Better Measure of Institutional Informed Trading

Although many studies show that the presence of institutional investors facilitates the incorporation of accounting information into financial markets, the evidence of informed trading by institutions is rather limited in the extant literature. We address these inconsistent findings by proposing PC_NII, percentage changes in the number of a stock's institutional investors, as a novel informed trading measure. PC_NII is better able to detect informed trading than are changes in institutional ownership (ΔIO)—the measure commonly used in previous studies—because (i) entries and exits are usually triggered by substantive private information and (ii) only a small fraction of institutions have superior information. As conjectured, PC_NII subsumes the information content of ΔIO and other institutional trading and herding measures in the forecast of stock returns, and its strong predictive power for stock returns reflects mainly its close correlation with future earnings surprises. We also show that PC_NII helps address empirical issues that require a reliable measure of institutional informed trading.     

Discretionary Disclosures to Risk‐Averse Traders: A Research Note

Verrecchia (1983) investigates a manager's incentives for costly, discretionary disclosure of his information to risk‐averse traders when the functional form of prices is exogenously specified. We extend Verrecchia (1983) by deriving the endogenously determined functional form of prices that would arise when all traders have constant risk tolerance. We show that these endogenously determined prices are inconsistent with the assumed prices in Verrecchia (1983) when the manager elects to not disclose. We derive the manager's disclosure strategy for our setting and extend the comparative static results in Verrecchia (1990) for risk‐neutral traders to a setting where traders have constant risk tolerance and prices are endogenously derived. Further, in our setting, discretionary disclosure does not affect how traders price risk of different outcomes. Also, we offer a representation of risk‐averse traders' prices using risk‐adjusted distributions. Finally, these results provide implications for empirical‐archival discretionary disclosure studies.     

Réactions du Marché d’Actions aux Chocs sur les Taux d’Intérêt de Court Terme,le Cas d’un Marché Emergent: la Bourse Régionale des Valeurs Mobilières (BRVM)

Abstract: Macroeconomics in general and interest rate policy in particular are believed, from a theoretical point of view, to act on stock market movements. This paper discusses this issue in the case of the West African stock market by studying the Regional Securities Exchange (la Bourse Régionale des Valeurs Mobilières (BRVM)) stock market reactions to interest rates innovations. Our results, based on VAR analysis, show that the BRVM stock market does not react immediately to short‐run interest rates’ innovations. Nevertheless, backed reactions occur in imminent periods: at the earliest in the second period and at the latest in the sixth period according to VAR models used. Long‐term effects of short‐term interest rates’ innovations on stock prices returns depend on models specified, on the kind of interest rate and on data frequency. Thus, the long‐term effect of central bank rent rates’ innovations is relatively more important than the one related to interbank rate's innovations. The previous situation of the market is, however, the main determinant of the change of stock prices. Our results show also that stock prices and short‐run interest rates have a similar reaction to both exchange rate and inflation rate's innovations.

Horizon‐Dependent Underreaction in Financial Analysts' Earnings Forecasts*

This paper provides empirical evidence that underreaction in financial analysts' earnings forecasts increases with the forecast horizon, and offers a rational economic explanation for this result. The empirical portion of the paper evaluates analysts' responses to earnings‐surprise and other earnings‐related information. Our empirical evidence suggests that analysts' earnings forecasts underreact to both types of information, and the underreaction increases with the forecast horizon. The paper also develops a theoretical model that explains this horizon‐dependent analyst underreaction as a rational response to an asymmetric loss function. The model assumes that, for a given level of inaccuracy, analysts' reputations suffer more (less) when subsequent information causes a revision in investor expectations in the opposite (same) direction as the analyst's prior earnings‐forecast revision. Given this asymmetric loss function, underreaction increases with the risk of subsequent disconfirming information and with the disproportionate cost associated with revision reversal. Assuming that market frictions prevent prices from immediately unraveling these analyst underreac‐tion tactics, investors buying (selling) stock on the basis of analysts' positive (negative) earnings‐forecast revisions also benefit from analyst underreaction. Therefore, the asymmetric cost of forecast inaccuracy could arise from rational investor incentives consistent with a preference for analyst underreaction. Our incentives‐based explanation for underreaction provides an alternative to psychology‐based explanations and suggests avenues for further research.     

Private Intermediary Innovation and Market Liquidity: Evidence from the Pink Sheets® Market

In 2007, Pink Sheets LLC assigned each Pink Sheets^® company to a disclosure tier and on its website affixed a colorful graphic to its stock symbol signifying the company's public disclosure level. This unique innovation allows us to investigate the impact of increased salience of disclosure practices on liquidity. Using a difference‐in‐difference design, we find evidence that firms classified into the Current Information category experienced an increase in liquidity while firms classified into the No Information category experienced a decrease in liquidity, both relative to other unclassified over‐the‐counter firms. This suggests that increases in the salience of disclosure practices via assignment to disclosure tiers affect investors’ attention, leading to changes in trading behavior that ultimately translate into liquidity changes. We also provide evidence that some investors anticipated the resulting liquidity changes because stock returns around a key event date leading up to the release of the disclosure tiers are positively associated with subsequent liquidity changes.     

The Determinants and Consequences of Information Acquisition via EDGAR

Using a novel data set that tracks all web traffic on the SEC's EDGAR servers from 2008 to 2011, we examine the determinants and capital market consequences of investor information acquisition of SEC filings. The average user employs the database very few times per quarter and most users target specific filing types such as periodic accounting reports; a small subset of users employ EDGAR almost daily and access many filings. EDGAR activity is positively related with corporate events (particularly restatements, earnings announcements, and acquisition announcements), poor stock performance, and the strength of a firm's information environment. EDGAR activity is related to, but distinct from, other proxies of investor interest such as trading volume, business press articles, and Google searches. Finally, information acquisition via EDGAR, both to obtain earnings news and to provide context for it, has a positive influence on market efficiency with respect to earnings news. Overall, our results are important because they provide a unique, user‐based perspective on investor access of mandatory disclosures and its impact on price formation.     

Financial Statement Comparability and the Informativeness of Stock Prices About Future Earnings

We find that financial statement comparability enhances the ability of current period returns to reflect future earnings, as measured by the future earnings response coefficient (FERC). This suggests that comparability improves the informativeness of stock prices and allows investors to better anticipate future firm performance. In addition, using both the FERC and stock price synchronicity tests, we find that comparability increases the amount of firm‐specific information (rather than market/industry‐level information) reflected in stock prices. Analysts play an important role in improving stock price informativeness by producing more firm‐specific information when comparability is high. These findings suggest that comparability lowers the costs of gathering and processing firm‐specific information.     

The Mispricing of Cash Flows and Accruals at Different Life‐Cycle Stages

This paper employs the firm life‐cycle concept to extend our understanding of the mispricing of accrual and cash flow information by the stock market. We find that accruals and free cash flows are strongly (negatively) correlated in the maturity and decline stages of a firm's life cycle but not in the growth stage, suggesting that they capture unique information in the growth stage of the firm's life cycle but more correlated information in the later stages. Consistent with this finding, we show that the cash flows anomaly subsumes the accruals anomaly in maturity and decline stages, but not in the growth stage. Our findings contribute to the debate regarding the overlap between the two anomalies.     

Corporate Investment Incentives and Accounting‐Based Debt Covenants*

This paper studies the conditions under which accounting‐based debt covenants increase firm value in a setting that incorporates the conflicting incentives of shareholders, bondholders, and managers. We construct a model in which debt is needed to discipline managerial investment decisions despite endogenous compensation contracts. We show that accounting covenants increase value when (1) debt serves as a credible commitment to penalize poor investment decisions; (2) the firm faces other (exogenous) sources of uncertainty that can make debt risky despite good investment decisions; and (3) accounting information serves as a contractible proxy for firm's economic performance. In these circumstances, accounting covenants ensure that shareholders do not offer compensation schemes that would encourage bondholder wealth expropriation when the debt becomes risky. A covenant specifying a required level of accounting performance provides additional bondholder power when performance is low. An accounting‐based dividend covenant allows a disbursement to maintain investment incentives when performance is high without allowing dividend‐based expropriation. The optimal covenants depend on the reliability of accounting information, and the interaction between accounting performance and the different incentive conflicts provides new insight into the empirical literature on accounting‐based covenants.     

The Relation between Aggregate Earnings and Security Returns over Long Intervals*

This paper provides a theoretical explanation and consistent empirical evidence for the increase in the contemporaneous correlation between returns and aggregate earnings as the return interval is lengthened. Consistent with intuition and with Easton, Harris, and Ohlson 1992, the analysis shows that aggregation over time renders the lag in accounting recognition relatively less important and thus improves the returns‐earnings R². Interestingly, the analysis also reveals that aggregating earnings over longer periods increases the positive covariance between aggregate earnings and the accounting lag, which may further increase the R². This positive covariance can lead to an earnings coefficient greater than one over some range of aggregation, which is consistent with the findings of Easton et al. that over the 10‐year interval the returns‐earnings regression slope coefficient is greater than one (1.7). The empirical results highlight the fact that the slope coefficient, which is greater than one and increasing with the interval, accounts for much of the increment to the returns‐earnings R². In fact, constraining the slope coefficient to be one results in an R² of 11 percent for the 10‐year interval, which is considerably lower than the R² of 47 percent when the regression is unconstrained. Hence, the positive covariance between current earnings and the accounting lag, rather than the diminishing effect of the accounting lag, appears to be the dominant explanation for the observed high R² over long intervals.
