Knowledge that Transforms

We examine the information transmission role of stock recommendation revisions by sell-side security analysts. Revisions are associated with economically insignificant mean price reactions and often piggyback on recent news, events, long-term momentum, and short-run contrarian return predictors, typically downgrading after bad news and upgrading after good news. However, the revisions are usually information-free for investors. The findings go against the long-standing view that recommendations are an important means by which analysts assimilate information into stock prices. They disagree with the view of policymakers that analysts’ stock picks materially impact stock prices.

I examine the effect of the accounting standard for derivative instruments (SFAS No. 133) on corporate risk-management behavior. I classify a derivative user as an “effective hedger” (EH firm) if its risk exposures decreased after the initiation of the derivatives program, and as an “ineffective hedger/speculator” (IS firm) otherwise. I find that volatility of cash flows and risk exposures related to interest rate, foreign exchange rate, and commodity price decrease significantly for IS firms but not for EH firms, suggesting that IS firms engaged in more prudent risk-management activities after the adoption of SFAS No. 133.

Prior evidence that higher-quality financial reporting improves capital investment efficiency leaves unaddressed whether it reduces over- or under-investment. This study provides evidence of both in documenting a conditional negative (positive) association between financial reporting quality and investment for firms operating in settings more prone to over-investment (under-investment). Firms with higher financial reporting quality also are found to deviate less from predicted investment levels and show less sensitivity to macro-economic conditions. These results suggest that one mechanism linking reporting quality and investment efficiency is a reduction of frictions such as moral hazard and adverse selection that hamper efficient investment.

We investigate the effects of mergers on the career outcomes of financial analysts. We hypothesize and find that analysts with good earnings forecast performance experience higher turnover during mergers, target analysts are more likely to turnover and the existence of a competing analyst in a merger counter party also increases analyst turnover. We analyze the promotion of analysts to research executive positions and find that analysts with greater experience and especially experienced stars are more likely to be promoted. Finally, we document that analyst turnover is associated with decreases in research quality at the merged firms post-merger.

We examine the effect of earnings surprises on changes in information asymmetry. We hypothesize and find that asymmetry is lower (higher) in the quarter following positive (negative) earnings surprises compared to firms that meet the consensus analyst earnings forecast. The relations between earnings surprises and information asymmetry are stronger when the surprises are more likely to capture investors’ attention. Examining the source of these changes, we show that decreased information search activities is the most important factor for asymmetry declining after positive surprises; for negative surprises, decreased uninformed trading plays a dominant role increasing asymmetry.

Prior studies suggest that auditors with short tenure are associated with lower earnings quality because of the lack of client-specific knowledge and/or low balling. In this study, we examine whether industry specialization of auditors and low balling affect the association between auditor tenure and earnings quality. We find that the association between shorter auditor tenure and lower earnings quality is weaker for firms audited by industry specialists compared to non-specialists. In addition, we do not find results consistent with the low balling explanation.

We investigate the relation between perceived competition and voluntary disclosure in the absence of capital market incentives by examining private UK companies, which have the option to withhold sales and costs of sales information from their publicly-filed accounts. We survey managers about their companies’ competitive environments and we calculate archival measures of industry competition. We find that managers are more likely to withhold information about sales and costs if they perceive that current or potential competition is strong. Consistent with disclosure being costlier for successful firms, we also find that more profitable companies are more likely to withhold information.

Dichev and Tang [2009. Earnings volatility and earnings predictability. Journal of Accounting and Economics, this issue, doi:10.1016/j.jacceco.2008.09.005] document the predictive power of past earnings volatility for the persistence of current earnings. We revisit their findings to verify the incremental explanatory power of this effect and to study whether the predictive power of past earnings volatility is priced in stock returns. We also discuss motives for the study of earnings persistence. Our findings indicate that the relation between past earnings volatility and earnings persistence is robust to the additional controls and to a correction for sampling bias, but that earnings volatility does not predict stock returns.

We examine the relation between internal control quality and the accuracy of management guidance. Consistent with managers in firms with ineffective internal controls relying on erroneous internal management reports when forming guidance, we document less accurate guidance among firms reporting ineffective internal controls. This relation extends to a change analysis, and the impact of ineffective internal controls on forecast accuracy is three times larger when the weakness relates to revenues or cost of goods sold—inputs particularly relevant to forecasting earnings. We conclude that internal control quality has an economically significant effect on internal management reports and thus decisions based on these figures.

We examine changes in the disclosure behavior of firms involved in 827 disclosure-related class-action securities litigation cases filed between 1996 and 2005. We find no evidence that the firms in our sample respond to the litigation event by increasing or improving their disclosures to investors. Rather, we find consistent evidence that firms reduce the level of information provided post-litigation. Our results suggest that the litigation process encourages firms to decrease the provision of disclosures for which they may later be held accountable, despite the increased protections afforded by the Private Securities Litigation Reform Act of 1995.
