Information efficiency of the U.S. credit default swap market: Evidence from earnings surprises

The credit default swap (CDS) market attracted much debate during the 2008 financial crisis. Opponents of CDS argue that CDS could lead to financial instability as it allows speculators to bet against companies and make the crisis worse. Proponents of CDS believe that CDS could increase market competition and benefit hedging activities. Moreover, an efficient CDS market can serve as a barometer to regulators and investors regarding the credit health of the underlying reference entity. We investigate information efficiency of the U.S. CDS market using evidence from earnings surprises. Our findings confirm that negative earnings surprises are well anticipated in the CDS market in the month prior to the announcement, with both economically and statistically stronger reactions for speculative-grade firms than for investment-grade firms. On the announcement day, for both positive and negative earnings surprises, the CDS spread for speculative-grade firms presents abnormal changes. Moreover, there is no post-earnings announcement drift in the CDS market, which is in direct contrast to the well-documented post-earnings drift in the stock market. Our evidence supports the efficiency of the CDS market.     

The Extreme Future Stock Returns Following I/B/E/S Earnings Surprises

We investigate the stock returns subsequent to quarterly earnings surprises, where the benchmark for an earnings surprise is the consensus analyst forecast. By defining the surprise relative to an analyst forecast rather than a time‐series model of expected earnings, we document returns subsequent to earnings announcements that are much larger, persist for much longer, and are more heavily concentrated in the long portion of the hedge portfolio than shown in previous studies. We show that our results hold after controlling for risk and previously documented anomalies, and are positive for every quarter between 1988 and 2000. Finally, we explore the financial results and information environment of firms with extreme earnings surprises and find that they tend to be “neglected” stocks with relatively high book‐to‐market ratios, low analyst coverage, and high analyst forecast dispersion. In the three subsequent years, firms with extreme positive earnings surprises tend to have persistent earnings surprises in the same direction, strong growth in cash flows and earnings, and large increases in analyst coverage, relative to firms with extreme negative earnings surprises. We also show that the returns to the earnings surprise strategy are highest in the quartile of firms where transaction costs are highest and institutional investor interest is lowest, consistent with the idea that market inefficiencies are more prevalent when frictions make it difficult for large, sophisticated investors to exploit the inefficiencies.     

To beat or not to beat? The importance of analysts’ cash flow forecasts

We investigate the implications of firms’ benchmark-beating patterns with respect to analysts’ quarterly cash flow forecasts for firms’ current capital market valuation and their future performance. We hypothesize that nonnegative earnings surprises are more likely to be supported by real operating performance and signal higher earnings quality if they are achieved via higher than expected cash flows or lower than expected accruals. We show that firms beating analyst earnings forecasts have larger positive capital market reactions and larger earnings response coefficients if they beat analyst cash flow forecasts or report lower than expected accruals. We also demonstrate that these firms’ superior future performance may provide an economic justification for their more favorable market response. Our findings suggest that firms’ ability to beat analyst cash flow forecasts is informative regarding the quality of their earnings surprises.     

Management’s tone change, post earnings announcement drift and accruals

This study explores whether the management discussion and analysis (MD&A) section of Forms 10-Q and 10-K has incremental information content beyond financial measures such as earnings surprises and accruals. It uses a classification scheme of words into positive and negative categories to measure the tone change in the MD&A section relative to prior periodic SEC filings. Our results indicate that short window market reactions around the SEC filing are significantly associated with the tone change of the MD&A section, even after controlling for accruals and earnings surprises. We show that management’s tone change adds significantly to portfolio drift returns in the window of 2 days after the SEC filing date through 1 day after the subsequent quarter’s preliminary earnings announcement, beyond financial information conveyed by accruals and earnings surprises. The drift returns are affected by the ability of the tone change signals to help predict the subsequent quarter’s earnings surprise but cannot be completely attributed to this ability. We also find that the incremental information of management’s tone change depends on the strength of the firm’s information environment.     

Trading based on forecasts of earnings per share: A test of the efficient market hypothesis

In this paper the semi-strong form of the efficient market hypothesis is tested with a trading rule based on Box-Jenkins forecasts of earnings per share numbers. The quarterly earnings per share series are modeled for a number of firms. The models are updated quarter by quarter and investments are made in the stocks with the largest forecasted growth rates for the next quarter. The risk-adjusted performance of such a strategy is shown to be inconsistant with semi-strong market efficiency.     

The use of credit default swaps by bond mutual funds: Liquidity provision and counterparty risk

Corporate bond mutual funds increased their selling of credit protection in the credit default swaps (CDS) market during the 2007–2008 financial crisis. This trading activity was primarily in multi-name CDS, greater among larger and established funds, and directed toward counterparty dealers in financial distress. Funds that sold credit protection during the crisis experienced greater credit market risk and superior post-crisis performance, consistent with higher expected returns from liquidity provision. Funds using Lehman Brothers as a counterparty experienced abnormal outflows and returns of –2% immediately following Lehman's bankruptcy, suggesting that funds’ opportunistic trading in CDS exposed investors to counterparty risk.     

Does Investor Sentiment Affect Earnings Management?

I hypothesize and find that earnings management via accruals is driven partially by the prevailing market‐wide investor sentiment. Managers inflate earnings in periods of higher sentiment, but report more conservatively during periods of low sentiment. Moreover, the likelihood of income‐increasing earnings management to avoid negative earnings surprises is also positively associated with investor sentiment. These results are robust to: (i) controls for time‐varying firm characteristics such as growth, investment opportunity sets, future profitability, leverage and size; (ii) macroeconomic variables such as future inflation, GDP growth, and growth in industrial production; (iii) multiple proxies for investor sentiment; and (iv) discretionary revenues as alternative measure of earnings management. Cross‐sectional analyses reveal that firms whose stock returns co‐move more with investor sentiment are more (less) likely to manage earnings upward via abnormal accruals in quarters of higher (lower) sentiment. The findings of managers’ strategic use of abnormal accruals show the need for increased attention from boards of directors, auditors and regulators to heightened managerial incentives to overstate earnings and to report optimistic earnings numbers during periods of high investor sentiment.     

Are credit default swaps still a sideshow? How information flow between equity and CDS markets has changed since the financial crisis

We examine the information flow between equity and credit default swap (CDS) markets using firm-level returns data before and after the global financial crisis. Before the crisis, the information flow was unidirectional, with equity returns leading CDS returns. While equity returns continue to lead CDS returns after the crisis, we find that the speed of adjustment of the CDS market to equity markets has increased during this period. We also find evidence of a bidirectional flow of information between these markets, with equity returns responding to credit protection returns in the postcrisis period. The quicker response of CDS spreads to equity returns during the postcrisis period primarily occurs among entities with lower credit ratings. In contrast, the response of equity returns to lagged CDS returns during the postcrisis period is observed among firms across different credit rating categories; however, the magnitude of the response is higher among those with lower credit ratings.     

The pricing of accruals quality in credit default swap spreads

We examine the association between accounting information risk, measured with accruals quality (AQ), and credit spreads, primarily measured with credit default swap (CDS) spreads. Theoretically, AQ measures the precision with which accruals map into cash flows. Better AQ implies a more precise estimate of future cash flows and, we predict, a reduction in credit spreads due to resulting lower uncertainty regarding the ability to meet debt interest and principal payments. In support of this hypothesis, we find a negative relationship between AQ and CDS spreads whereby better AQ is associated with lower CDS spreads. Additionally, we investigate the components of total AQ and find that innate AQ is more strongly associated with CDS spreads than is discretionary AQ. We further show that AQ moderates the market's pricing of earnings: the relationship between earnings and CDS spreads weakens as AQ worsens. Together, our results indicate that accounting information risk is priced in credit spreads and that the CDS market responds not only to the level of earnings, but the quality thereof as well.     

Market perceptions of discretionary accruals by debt renegotiating firms during economic downturn

This study addresses how a stock market prices earnings components around a sudden and severe economic downturn. In particular, the study examines the market valuation of discretionary accruals for debt renegotiating Malaysian firms during the Asian financial crisis. Our analysis shows that negative discretionary accruals for debt renegotiating firms are associated with higher market values of equity and are not related to the firms' future earnings. These findings are consistent with investors placing a positive value on the probability that negative accruals increase the likelihood that concessions can be extracted from lenders during renegotiation. In contrast, discretionary accruals for a control sample of non-debt renegotiating firms are not significantly associated with stock prices but are positively associated with future earnings.     

Abnormal trading volume,news and market efficiency: Evidence from the Jamaica Stock Exchange

This paper investigates market efficiency of the Jamaica Stock Exchange (JSE). Together, weak and semi-strong form efficiency claim that historical and newly released public information do not predict future stock price movement. We test both forms of market efficiency by analyzing stock price behavior during times of abnormal trading volume and around the release dates of earnings information. Abnormal trading volume may be driven by liquidity demand or reflect new or private information flow to the market. Using JSE data over the period 2000 to 2021, we find price dynamics consistent with price pressure as firms experience negative abnormal returns on the day of abnormal trading activity but offsetting positive abnormal stock returns on the following day. Further findings show post earnings announcement drift on the JSE. Taken as a whole, the evidence suggests violations of market efficiency and has implications for capital allocation in this emerging market.     

POST-ANNOUNCEMENT DRIFTS ASSOCIATED WITH DIVIDEND CHANGES

In this paper I assess the presence of post-announcement drifts associated with dividend changes after controlling for earnings surprises. All quarterly cash dividend changes announced by firms listed on the New York Stock Exchange (NYSE) and American Stock Exchange (AMEX) from 1974 through 1989 are examined. The results show that significant post-announcement drifts associated with dividend changes are present after controlling for earnings surprises. However, the results are not conclusive on whether the market fully incorporates the simple time-series properties of dividends.     

The debt market relevance of management earnings forecasts: evidence from before and during the credit crisis

We investigate the credit market’s response via changes in credit default swap (CDS) spreads to management earnings forecasts and evaluate the importance of these forecasts relative to earnings news during the periods before and during the recent credit crisis. We document that credit markets react significantly to management forecast news and that the reactions to forecast news are stronger than to actual earnings news. Consistent with the asymmetric payoffs to debt holders, the forecast news is mainly relevant for firms with poor credit rating or announcing bad news. We also show that the relevance of management forecasts to credit markets is particularly strong during periods of high uncertainty, as experienced during the recent credit crisis.     

Accruals and the Conditional Equity Premium

Accruals correlate closely with the determinants of the conditional equity premium at both the firm and the aggregate levels. The common component of firm‐level accruals, which cannot be diversified away by aggregation, explains the positive relation between aggregate accruals and future stock market returns. The residual component, which accounts for most variation in firm‐level accruals, is responsible for the negative cross‐sectional relation between firm‐level accruals and future stock returns. Consistent with the risk‐based explanation, aggregate accruals, as a proxy for the conditional equity premium, forecast changes in aggregate economic activity. Moreover, we document a similar comovement of earnings with the conditional equity premium at both the firm and the aggregate levels, which helps explain the negative relation between changes in aggregate earnings and contemporaneous market returns.     

Hierarchy of earnings thresholds based on discretionary accruals

Prior studies identify hierarchies of earnings thresholds based on distributions of earnings (e.g., Degeorge et al., 1999) and survey opinions of CFOs (Graham, Harvey, & Rajgopal, 2005). We complement extant literature by investigating a threshold hierarchy in the context of accounting discretion exercised by managers. We examine the relative extent of discretionary accruals used to achieve three earnings thresholds—avoiding losses, avoiding earnings declines, and avoiding negative earnings surprises. Our empirical findings suggest that managers are likely to use the largest amount of discretionary accruals to avoid earnings declines, and the least amount of discretionary accruals to avoid negative earnings surprises. Thus, this study identifies the hierarchy of the earnings thresholds based on accounting discretion used in financial reporting. We also find that the hierarchy remains stable over the last two decades during our sample period. Then, we provide several explanations for why managers are likely to exercise more accounting discretion to avoid earnings declines. These explanations include earnings smoothing, reduction of stock returns volatility, and signaling of future growth potential. Overall, this study provides new insights into accruals management behavior.     

How do stock-for-stock acquirers manage earnings? The accruals feature of real earnings management

This paper investigates whether stock-for-stock acquirers undertake real activities to manage earnings before merger announcements. Our results show that stock-for-stock acquirers present unusually high levels of credit sales and overproduction in the quarter immediately before the merger announcement. We also find that the accruals feature of real earnings management can explain the stock-for-stock acquirers’ high discretionary current accruals. In addition, stock-for-stock acquirer firms that accelerate their credit sales experience subsequent market underperformance. Overall, we provide a novel insight into the accruals feature of real earnings management.     

How do global investors differentiate between sovereign risks? The new normal versus the old

When global investors go into emerging markets or get out of them, how do they differentiate between economies? Has this behavior changed since the crisis of 2008 to reflect a “new normal”? We consider these questions by focusing on sovereign risk as reflected in monthly returns on credit default swaps (CDS) for 18 emerging markets and 10 developed countries. Tests for breaks in the time series of such returns suggest a new normal that ensued around October 2008 or soon afterwards. Dividing the sample into two periods and extracting risk factors from CDS returns, we find an old normal in which a single global risk factor drives half of the variation in returns and a new normal in which that risk factor becomes even more dominant. Surprisingly, in both the old and new normal, the way countries load on this factor depends not so much on economic fundamentals as on whether they are designated an emerging market.     

Accruals, Cash Flows and the Post‐Earnings‐Announcement Drift

Abstract:   Several prior studies have shown that cash flows have significantly greater impact on stock prices than accruals. We examine the implications of these findings for the post‐earnings‐announcement‐drift anomaly. We argue that, if investors under‐react to earnings news, then the larger price impact of cash flows causes the cash flow component of earnings news to predict future returns better than the accruals component. Consistent with this argument, we show that unexpected cash flows are more positively related to future returns, than are unexpected accruals. Also, unexpected cash flows are found to predict future returns above and beyond that predicted by earnings surprises. Finally, we show that a strategy that decomposes earnings news into its components significantly outperforms strategies based on earnings news alone. The results support under‐reaction explanations for the drift.     

Credit default swaps and the UK 2008–09 short sales ban

Most studies of the short sales ban of UK financial stocks from September 2008 to January 2009 fail to control for the UK’s worst ever banking crisis and the underlying increase in risk. This paper studies the ban’s impact on the 13 large financials with credit default swaps (CDS) and 20 smaller stocks without CDS. The results reveal that returns of banned stocks Granger cause CDS returns in the pre- and post-ban periods, but causality runs from CDS to stock returns during the ban period. Underlying risk proxied by the CDS probability of default increased during the ban and the immediate pre- and post-ban periods which highlights an endogeneity problem ignored in some studies. This increased risk provides a plausible rationale for why CDS and related equity bid-ask spreads - which increased during the ban period – failed to fall significantly in the post-ban period. Panel regression results indicate that probability of default was an important economic determinant of stock bid-ask spreads during the ban period. Finally, our results suggest that the ban offered direct price support for the smaller non-CDS stocks during the ban period and indirect support for CDS stocks from their pre-ban to their post-ban levels.     

Does the Stock Market See a Zero or Small Positive Earnings Surprise as a Red Flag?

This study shows that firms collectively incur a cost for managing earnings and analyst expectations to meet earnings forecasts. We compare the coefficient in the regression of abnormal stock returns on earnings surprise (the earnings response coefficient [ERC]) across ranges of earnings surprises. The ERC for earnings surprises in the range [0, 1¢] is significantly lower than ERCs for earnings surprises in adjacent ranges for firm-quarters in the early and mid 2000s, but not for those in the 1990s. The results are robust to controlling for the sign of estimated discretionary accruals and the trajectory of analyst earnings forecasts. We further find that investors are right to be skeptical about earnings surprises in the range [0, 1¢]. The relation of future earnings surprise with current earnings surprise is more negative for current earnings surprises in that range than for those in any other range. Evidence also suggests analysts react negatively to earnings surprises in that range.
