Buys, holds, and sells: The distribution of investment banks’ stock ratings and the implications for the profitability of analysts’ recommendations

Journal of Accounting and Economics 2006 41(1-2), 87-117
This paper analyzes the distribution of stock ratings at investment banks and brokerage firms and examines whether these distributions can predict the profitability of analysts’ recommendations. We document that the percentage of buys decreased steadily starting in mid-2000, likely due, at least partly, to the implementation of NASD Rule 2711, requiring the public dissemination of ratings distributions. Additionally, we find that a broker's ratings distribution can predict recommendation profitability. Upgrades to buy (downgrades to hold or sell) issued by brokers with the smallest percentage of buy recommendations significantly outperformed (underperformed) those of brokers with the greatest percentage of buys.

Management of the loss reserve accrual and the distribution of earnings in the property-casualty insurance industry

Journal of Accounting and Economics 2003 35(3), 347-376
We document that property-casualty insurers with small positive earnings understate loss reserves relative to insurers with small negative earnings. Furthermore, loss reserves are managed across the entire distribution of earnings, with the most income-increasing reserve accruals reported by small profit firms, and the most income-decreasing reserve accruals reported by firms with the highest earnings. We analyze this pattern separately for public, private, and mutual companies, and find that public companies and mutuals manage loss reserves to avoid losses, but that private companies do not. We also find evidence of reserve management to avoid losses by financially healthy and distressed firms.

Analyst Coverage and Intangible Assets

Journal of Accounting Research 2001 39(1), 1-34
This study examines the relation between analysts' incentives to cover firms and the extent of their intangible assets. Because intangible assets typically are unrecognized and estimates of their fair values are not disclosed, absent analyst coverage firms with more intangible assets likely have less informative prices. Accordingly, we expect analysts have greater incentives to cover firms with more intangible assets and, thus, predict they have higher analyst coverage. As predicted, we find that analyst coverage is significantly greater for firms with larger research and development and advertising expenses relative to their industry, and for firms in industries with larger research and development expense. We also predict and find that analyst coverage is increasing in firm size, growth, trading volume, equity issuance, and perceived mispricing, and is decreasing in the size of the firm's analysts' brokerage houses and the effort analysts expend to follow the firm. These findings indicate that analyst coverage depends on private benefits and costs of covering a firm. We also test hypotheses related to analyst effort. We predict and find that analysts expend greater effort to follow firms with more intangible assets, after controlling for other factors associated with analyst effort. Our evidence indicates that intangible assets, most of which are not recognized in firms' financial statements, are associated with greater incentives for analysts to cover such firms, and greater costs of coverage. An open question is whether financial statement recognition of intangible assets could more efficiently provide information about such assets to investors.

Bankruptcy in groups

Review of Accounting Studies 2024 29(4), 3449-3496 open access
We examine bankruptcy within business groups. Groups have incentives to support financially distressed subsidiaries, as the bankruptcy of a subsidiary may impose severe costs on the group as a whole. This is in part because, in several countries, bankruptcy courts often “pierce the corporate veil” and hold groups liable for their distressed subsidiaries’ obligations as if they were their own. Using a large cross-country sample of group-affiliated firms, we show that, by reallocating resources within the corporate structure, business groups actively manage intra-group credit risk to prevent costly within-group insolvencies. Moreover, we document that recent regulatory changes in the approval and disclosure of related party transactions are costly for business groups in that they constrain their ability to shield their subsidiaries from credit-risk shocks. Our study informs the current regulatory debate on related party transactions by highlighting an important cost of anti-self-dealing regulation.

Two-Sided Matching in the Audit Market

The Accounting Review 2025 100(3), 363-394
We develop and estimate a two-sided matching model of auditors and clients. We find evidence that auditors and clients engage in matching based on their preferences on both observable and unobservable characteristics. This matching appears to partly explain the “Big 4 effect” on audit outcomes: after controlling for the effects of matching, we find that the positive influence of having a Big 4 auditor on serious restatements and serious comment letter conversations with the SEC either weakens or disappears. Collectively, our results highlight the importance of accounting for two-sided matching between auditors and clients in understanding the influence of auditors on clients’ financial reporting practices.

Can Investors Profit from the Prophets? Security Analyst Recommendations and Stock Returns

Journal of Finance 2001 56(2), 531-563
We document that purchasing (selling short) stocks with the most (least) favorable consensus recommendations, in conjunction with daily portfolio rebalancing and a timely response to recommendation changes, yield annual abnormal gross returns greater than four percent. Less frequent portfolio rebalancing or a delay in reacting to recommendation changes diminishes these returns; however, they remain significant for the least favorably rated stocks. We also show that high trading levels are required to capture the excess returns generated by the strategies analyzed, entailing substantial transactions costs and leading to abnormal net returns for these strategies that are not reliably greater than zero.
