Momentum Strategies

We examine whether the predictability of future returns from past returns is due to the market's underreaction to information, in particular to past earnings news. Past return and past earnings surprise each predict large drifts in future returns after controlling for the other. Market risk, size, and book–to–market effects do not explain the drifts. There is little evidence of subsequent reversals in the returns of stocks with high price and earnings momentum. Security analysts' earnings forecasts also respond sluggishly to past news, especially in the case of stocks with the worst past performance. The results suggest a market that responds only gradually to new information.     

Econometrics of the Basu Asymmetric Timeliness Coefficient and Accounting Conservatism

A substantial literature investigates conditional conservatism, defined as asymmetric accounting recognition of economic shocks (“news”), and how it depends on various market, political, and institutional variables. Studies typically assume the Basu [1997] asymmetric timeliness coefficient (the incremental slope on negative returns in a piecewise‐linear regression of accounting income on stock returns) is a valid conditional conservatism measure. We analyze the measure's validity, in the context of a model with accounting income incorporating different types of information with different lags, and with noise. We demonstrate that the asymmetric timeliness coefficient varies with firm characteristics affecting their information environments, such as the length of the firm's operating and investment cycles, and its degree of diversification. We particularly examine one characteristic, the extent to which “unbooked” information (such as revised expectations about rents and growth options) is independent of other information, and discuss the conditions under which a proxy for this characteristic is the market‐to‐book ratio. We also conclude that much criticism of the Basu regression misconstrues researchers’ objectives.     

Equilibrium "Anomalies"

Many empirical “anomalies” are actually consistent with the single beta capital asset pricing model if the empiricist utilizes an equity‐only proxy for the true market portfolio. Equity betas estimated against this particular inefficient proxy will be understated, with the error increasing with the firm's leverage. Thus, firm‐specific variables that correlate with leverage (such as book‐to‐market and size) will appear to explain returns after controlling for proxy beta simply because they capture the missing beta risk. Loadings on portfolios formed on relative leverage and relative distress completely subsume the powers of the Fama and French (1993) returns to small minus big market capitalization (SMB) portfolios and returns to high minus low book‐to‐market (HML) portfolios factors in explaining cross‐sectional returns.     

Stock Valuation and Learning about Profitability

We develop a simple approach to valuing stocks in the presence of learning about average profitability. The market‐to‐book ratio (M/B) increases with uncertainty about average profitability, especially for firms that pay no dividends. M/B is predicted to decline over a firm's lifetime due to learning, with steeper decline when the firm is young. These predictions are confirmed empirically. Data also support the predictions that younger stocks and stocks that pay no dividends have more volatile returns. Firm profitability has become more volatile recently, helping explain the puzzling increase in average idiosyncratic return volatility observed over the past few decades.     

On the Stability of the Cross‐Section of Expected Stock Returns in the Cross‐Section: Understanding the Curious Role of Share Turnover

In this paper, we shed further light on cross‐sectional predictors of stock return performance. Specifically, we explore whether the cross‐section of expected stock returns is robust within stock groups sorted by past monthly return. We find that the book/market and momentum effects are remarkably robust to sorting on past returns. However, share turnover is negatively related to future returns for stocks with abnormally low stock price performance in the recent past, but postively related to returns for well‐performing stocks. This casts doubt on the use of turnover as a liquidity proxy, but is consistent with turnover being a proxy for momentum trading which pushes prices in the direction of past price movements. Our results are robust to both NYSE/AMEX and Nasdaq stocks, and also robust to stratifying the sample by time period.     

Employee approval of CEOs and firm value: Evidence from Employees' choice awards

Using Glassdoor's list of “Top CEOs by Employees' Choice,” we adopt a regression discontinuity (RD) specification to establish a causal link between the employee approval of CEOs and firm value. Having a CEO included in the top list results in an increase in firm performance in both stock returns and return on assets. Having a top CEO significantly increases a firm's employee efficiency, attraction to future employees, hiring of high-quality laborers such as inventors, and attraction to the customers. Our findings establish that the CEO-employee relationship is an important, though intangible, component of a corporation, and we emphasize the critical role of perceived corporate culture in the spirit of Guiso et al. (2015).     

The Pragmatic Theory of the Firm

Four key ideas provide the foundation for the pragmatic theory of the firm, which is expecially useful for managements and boards in developing an understanding of how companies create long‐term value for the benefit of all stakeholders. First, and a necessary point of departure, is clarity about the purpose of the firm. Maximizing shareholder value is viewed not as the social purpose of the firm, but as a consequence of a company's effectiveness in carrying out a purpose that recognizes the benefits of success to all key corporate stakeholders. Second, a company's knowledge‐building proficiency, in relation to that of its competitors, is viewed as the primary determinant of its long‐term performance. Nurturing and sustaining a knowledge‐building culture facilitates the discovery of obsolete assumptions and early adaptation to a changing environment. Third, the theory avoids “compartmentalizing” a company's activities into silos by treating the firm as a holistic system. A key component of the theory that quantifies corporate performance is the life‐cycle framework in which economic returns exhibit “competitive fade” over the long term. This holistic way of thinking provides insights about intangible assets and other sources of excess shareholder returns. Fourth, managing corporate risk should focus on identifying and removing all major obstacles to achieving the firm's purpose. Such obstacles can lead to value destruction through, for example, unethical behavior and all forms of shortsighted failure to recognize and make the most of opportunities to increase long‐run productivity and value. This theory of the firm is pragmatic in the sense that it aims to produce insights about a company's (or business unit's) performance that can improve management's decisions, especially in allocating capital and other corporate resources. The author uses John Deere's life‐cycle track record over the past 60 years to illustrate a successful application of the theory.     

Analyst Forecasts and the Cross Section of European Stock Returns

We examine revisions to earnings forecasts by equity analysts and their role in predicting stock returns. We provide evidence that European stocks with net upward revised forecasts earn higher future returns than otherwise similar stocks. This effect is not concentrated in small stocks, stocks with low analyst coverage, or stocks with low book‐to‐market ratios. We find differences in the return continuation patterns of stocks with upward versus downward revisions, namely, bad news travels quickly, but good news travels slowly. This result is consistent with investors' attaching greater significance to poor earnings forecasts, but adopting a wait‐and‐see approach to good news.     

Enterprise Risk Management: Theory and Practice

The Chief Risk Officer of Nationwide Insurance teams up with a distinguished academic to discuss the benefits and challenges associated with the design and implementation of an enterprise risk management program. The authors begin by arguing that a carefully designed ERM program—one in which all material corporate risks are viewed and managed within a single framework—can be a source of long‐run competitive advantage and value through its effects at both a “macro” or company‐wide level and a “micro” or business‐unit level. At the macro level, ERM enables senior management to identify, measure, and limit to acceptable levels the net exposures faced by the firm. By managing such exposures mainly with the idea of cushioning downside outcomes and protecting the firm's credit rating, ERM helps maintain the firm's access to capital and other resources necessary to implement its strategy and business plan. At the micro level, ERM adds value by ensuring that all material risks are “owned,” and risk‐return tradeoffs carefully evaluated, by operating managers and employees throughout the firm. To this end, business unit managers at Nationwide are required to provide information about major risks associated with all new capital projects—information that can then used by senior management to evaluate the marginal impact of the projects on the firm's total risk. And to encourage operating managers to focus on the risk‐return tradeoffs in their own businesses, Nationwide's periodic performance evaluations of its business units attempt to refl ect their contributions to total risk by assigning risk‐adjusted levels of “imputed” capital on which project managers are expected to earn adequate returns. The second, and by far the larger, part of the article provides an extensive guide to the process and major challenges that arise when implementing ERM, along with an account of Nationwide's approach to dealing with them. Among other issues, the authors discuss how a company should assess its risk “appetite,” measure how much risk it is bearing, and decide which risks to retain and which to transfer to others. Consistent with the principle of comparative advantage it uses to guide such decisions, Nationwide attempts to limit “non‐core” exposures, such as interest rate and equity risk, thereby enlarging the firm's capacity to bear the “information‐intensive, insurance‐ specific” risks at the core of its business and competencies.     

Does the media help or hurt retail investors during the IPO quiet period?

We examine how the media influences retail trade and market returns during the “quiet period” that follows a firm's IPO. We find that more media coverage during this period is associated with more purchases by retail investors and that such purchases are attention-driven, rather than information-based. Further, these retail trades are negatively associated with stock returns at the firm's first earnings announcement post-IPO. Our results suggest that media coverage, combined with market frictions that limit price efficiency in the post-IPO period, leads to worse investing outcomes for retail investors.     

THE INVESTMENT OPPORTUNITY SET AND ITS PROXY VARIABLES

We use a real options approach to evaluate the performance of several proxy variables for a firm's investment opportunity set. The results show that, on a relative scale, the market‐to‐book assets ratio has the highest information content with respect to investment opportunities. Although both the market‐to‐book equity and the earnings–price ratios are related to investment opportunities, they do not contain information that is not already contained in the market‐to‐book assets ratio. Consistent with this finding, a common factor constructed from several proxy variables does not improve the performance of the market‐to‐book assets ratio.     

Stock Repurchases and Excess Returns: An Empirical Examination

The excess returns associated with repurchase announcements are viewed largely as a reaction to management's statement that the firm's shares are underpriced; management's signal provides new information that enhances the firm's market value. Although earlier studies have found the excess return to be closely related to the premium set by managment, other factors play a part in determining both the market reaction and the premium level set by management. Among these factors ar relative market capitalization, holdings by institutions, immediate alternative uses for cash, level of insider control, recent stock price performance, relative size of the tender offer, and the resultant change in the firm's capital structure.     

Additional evidence on transparency and bank financial performance

This paper examines the relationship between volatility and the probability of occurrence of expected extreme returns in the Canadian market. Four measures of volatility are examined: implied volatility from firm option prices, conditional volatility calculated using an EGARCH model, idiosyncratic volatility, and expected shortfall. A significantly positive relationship is observed between a firm's idiosyncratic volatility and the probability of occurrence of an extreme return in the subsequent month for firms. A 10% increase in idiosyncratic volatility in a given month is associated with the probability of an extreme shock in the subsequent month (top or bottom 1.5% of the returns distribution) of 26.4%. Other firm characteristics, including firm age, price, volume and book‐to‐market ratio, are also shown to be significantly related to subsequent firm extreme returns. The effects of conditional and implied volatility are mixed. The E‐GARCH and expected shortfall measures of conditional volatility are consistent with mean reversion: high short term realizations of conditional volatility foreshadow a lower probability of extreme returns.     

How Much New Information Is There in Earnings?

We quantify the relative importance of earnings announcements in providing new information to the share market, using the R² in a regression of securities' calendar‐year returns on their four quarterly earnings‐announcement “window” returns. The R², which averages approximately 5% to 9%, measures the proportion of total information incorporated in share prices annually that is associated with earnings announcements. We conclude that the average quarterly announcement is associated with approximately 1% to 2% of total annual information, thus providing a modest but not overwhelming amount of incremental information to the market. The results are consistent with the view that the primary economic role of reported earnings is not to provide timely new information to the share market. By inference, that role lies elsewhere, for example, in settling debt and compensation contracts and in disciplining prior information, including more timely managerial disclosures of information originating in the firm's accounting system. The relative informativeness of earnings announcements is a concave function of size. Increased information during earnings‐announcement windows in recent years is due only in part to increased concurrent releases of management forecasts. There is no evidence of abnormal information arrival in the weeks surrounding earnings announcements. Substantial information is released in management forecasts and in analyst forecast revisions prior (but not subsequent) to earnings announcements.     

A South African Success Story: Excellence in the Corporate Use of Capital and Its Social Benefits

South African companies have made great progress in improving corporate profitability since the nation became a full democracy in 1994. Using the “Cash Flow Return on Investment” (CFROI) method, the authors demonstrate that South African listed companies have been generating world‐beating levels of inflation‐adjusted return on capital over the past decade. But not all parts of the South African economy have benefited from this corporate success. Despite the impressive corporate returns, economic growth remains lackluster, constrained by confused labor and government policies. The authors recommend that South African policy makers aim to minimize uncertainty for the private sector by refraining from interventions with agendas that have little to do with expanding output or employment growth. Using terminology borrowed from Thomas Piketty's recent book, the two authors argue that what South Africa needs is not some way to limit investors' return on capital (r) but rather sound economic approaches to liberate growth (g). The authors would like to see the country's companies continue to generate high “r” while reinvesting their profits to produce more wealth‐creating “g.”     

New Paradigms in Stock Market Indexing

Considerable recent interest has been shown in a new set of stock‐market indices that are weighted by fundamental factors such as sales, earnings, dividends or book values, rather than by capitalization. In this paper, we analyze the performance of Fundamental Indexing? (“FI”). First, we show that the source of FI's recent excellent performance is not from its ability to systematically arbitrage mispricing in a noisy market but from increasing the portfolio's exposure to stocks with low price‐to‐book values and with small capitalizations. We find that FI does not produce a positive alpha when its excess returns are explained by the Fama‐French three‐factor model of CAPM beta, the value premium and the size premium. Second, we show that it is possible to construct a portfolio of exchange‐traded funds with similar factor loadings that can replicate, and sometimes, even outperform FI. However, we caution investors not to expect consistent outperformance from portfolios tilted towards value and small‐cap stocks. Historical data shows evidence of mean reversion in the performance of such strategies.     

Asset Pricing Implications of Nonconvex Adjustment Costs and Irreversibility of Investment

This paper derives a real options model that accounts for the value premium. If real investment is largely irreversible, the book value of assets of a distressed firm is high relative to its market value because it has idle physical capital. The firm's excess installed capital capacity enables it to fully benefit from positive aggregate shocks without undertaking costly investment. Thus, returns to equity holders of a high book‐to‐market firm are sensitive to aggregate conditions and its systematic risk is high. Simulations indicate that the model goes a long way toward accounting for the observed value premium.     

The Purpose of the Firm,Valuation, and the Management of Intangibles

This article provides a different way of thinking about, and responding to, four important issues that confront most public companies. First, in articulating the overarching corporate purpose, the author suggests a middle ground between shareholder value maximization and stakeholder theory that aims to achieve the end result of value maximization while taking a “holistic” view that meets most of the demands of stakeholder advocates. As described by the author, there are four critical steps for management and boards in creating such companies: (1) communicating a vision of the company and its purpose to employees as well as investors (and other key outsiders); (2) organizing to survive and prosper through efficiency and innovation; (3) working continuously to develop win‐win relationships with stakeholders and other companies; and (4) taking care of the environment and future generations. Second, in thinking about the corporate purpose and how to evaluate success in achieving it, managements and boards need a valuation model that provides a clear and insightful connection between long‐term corporate performance and market valuation, and how both might be expected to change as the firm matures. A strong case is presented for the life‐cycle valuation model, widely used by money management organizations, in which a company's projected cash flows reflect an expected “fade” in both economic returns on capital and reinvestment rates. The potential uses of this model are illustrated using lifecycle corporate performance data for 3M during the past 50 years. Third, in an effort to capture the value of innovation and investment in intangible assets, the author presents an alternative to the accounting approach of capitalizing and amortizing such assets that attempts to capture their expected future benefits by using more favorable forecasts of long‐term fade rates. Fourth, the author shows how incorporating Life‐cycle Reviews for each of a company's business units as part of its Integrated Reporting could improve management's resource allocation decisions, help build a shareholder base of long‐term investors, and provide management with the support and confidence to resist Wall Street's excessive emphasis on quarterly earnings.     

Comparing the Post–Earnings Announcement Drift for Surprises Calculated from Analyst and Time Series Forecasts

Post–earnings announcement drift is the tendency for a stock's cumulative abnormal returns to drift in the direction of an earnings surprise for several weeks following an earnings announcement. We show that the drift is significantly larger when defining the earnings surprise using analysts' forecasts and actual earnings from I/B/E/S than when using a time series model based on Compustat earnings data. Neither Compustat's policy of restating earnings nor the inclusion of “special items” in reported earnings contribute significantly to the disparity in drift magnitudes. Rather, our results suggest that this disparity is attributable to differences between analyst forecasts and those of time‐series models—or at least to factors correlated with these differences. Further, we document that analyst forecasts lead to return patterns around future earnings announcements that differ from those observed when using time‐series models, suggesting that the two types of surprises may capture somewhat different forms of mispricing.     

EQUITY ISSUES AND TOBIN'S Q: NEW EVIDENCE REGARDING ALTERNATIVE INFORMATION RELEASE HYPOTHESES

Announcements of seasoned equity offerings are associated with a statistically significant negative market reaction. This finding is consistent with both the cash flow signaling and the free cash flow hypotheses. We test these hypotheses by examining whether revisions in analyst earnings forecasts and abnormal stock returns associated with equity offering announcements are related to the issuing firm's q-ratio. We find an inverse relation between revisions in analysts' earnings forecasts and q-ratios, and no relation between announcement-period abnormal returns and q-ratios. These findings provide direct evidence of the cash flow signaling hypothesis and, at best, indirect evidence of the free cash flow hypothesis.
