Do investors overreact to earnings warnings?

This study shows that contrary to what many managers argue, there is no overreaction to earnings warnings. Our sample consists of 986 firms that had significantly lower fourth-quarter earnings than analysts' forecasts during the period of 1983 to 1998. About 9% of these firms released quantitative earnings information while 6.5% of the firms disclosed qualitative earnings information prior to the formal earnings report dates. We find that although these firms experience significant stock price declines during the warning period, their share prices are still higher than the economic values, calculated using Ohlson's residual income model. Further, long-run operating and stock performance of these firms are not more positive than the performance of firms that do not warn. We also find that investor reaction to both warning and non-warning firms is positively related to the firms' long-run stock and operating performance. These findings support the argument that investors do not overreact to the warnings but base their reaction on anticipated long-term performance of the firms.     

Management disclosure bias and audit services

This paper considers the level of bias observed in management disclosures of earnings forecasts and historic earnings data in Australian prospectuses. Management forecasts and naïve forecasts derived from managements’ normalised historic data are analysed. A key focus is upon the possible association between such forecast bias and differential audit services performed upon the data. Audit firm size and level of engagement are modelled against bias. The full sample revealed no overestimation bias for any of the forecast models, but underestimation was observed for elements of the management and random walk naïve forecasts. Cross-sectionally, a significant association was observed between forecast bias and audit firm size across all three forecast models. Specifically, the audit firm size variable (Non Big-5/Big-5) was inversely associated with the extent to which forecasted and normalised historic earnings data were upwardly biased. On the other hand, the level of engagement was not a significant discriminator for forecast bias. These outcomes are contrasted against others reported elsewhere in the literature and suggest a risk in generalising across contexts. The findings imply a level of ‘disclosure management’ regarding company IPO forecasts and normalised historic accounting data, with forecast overestimation and error size more extreme when the monitoring expertise and/or reputation of auditors is lower (JEL D80, G14, M41, N27).     

Do brokerage houses add value? The market impact of UK sell-side analyst recommendation changes

This paper reports on the first full study investigating the economic role of sell-side analysts’ stock recommendations in the UK market. We also explore whether UK analysts are, in practice, influenced by the same biases as that reported for their US counterparts.We find that share prices are significantly influenced by analysts’ recommendation changes, not only at the time of the recommendation change but also in subsequent months. The price reaction to new sell recommendations is greater than the price reaction to new buy recommendations and exhibits post-recommendation drift which is consistent with initial underreaction to bad news. Returns generated are influenced, cross-sectionally, by factors associated with a firm's information environment and analyst incentives such as size, same-sign earnings forecast revisions and recommendation changes that skip a rank.We find that UK analysts’ investment recommendations in practice appear less susceptible to potential conflicts of interest than their US counterparts. The ratio of new sell to buy recommendations is higher in the UK and a greater proportion of such recommendations are accompanied by same-sign earnings forecast revisions than their equivalents in the US. We find brokerage house investment banking relationships do not appear to impact (adversely) on abnormal returns.

Ownership structure and earnings informativeness: Evidence from Korea

This paper examines the relationship between corporate ownership structure in Korea and the informativeness of earnings. Korean ownership structure is characterized by the dominance of one primary owner who also participates in firm management. Existing literature offers two alternative perspectives on the behavior of such owner-manager firms, convergence of interests, and management entrenchment hypotheses. We tested the alternative views to see how they are reflected in earnings informativeness. The results show that earnings are more informative as holdings of the owner increase, supporting the convergence of interest explanation for the owner-manager structure. Second, we examine the role of institutional investors and blockholders. On the one hand, institutions/blockholders have incentives to actively monitor management. However, on the other hand, institutions/blockholders may not render effective monitoring because they lack expertise, suffer from freerider problems, or strategically ally with management. These opposing views predict conflicting signs on the relation between the earnings informativeness and holdings of institutions/blockholders. We find that earnings informativeness increases with the holdings of institutions and blockholders. This supports the active monitoring role of institutions/blockholders. Finally, we test the relationship between earnings informativeness for chaebol (Korean business group)-affiliated companies vs. that for nonchaebol-affiliated companies, and find no significant relationship between the owner-largest shareholder's holdings and earnings informativeness. This provides evidence that for chaebol companies, the negative effect of management entrenchment/expropriation of minority shareholders offsets the positive effects. This phenomenon is stronger for chaebol-affiliated companies than for nonchaebol affiliates.     

Earnings, cashflows and returns: Functional relations and the impact of firm size

The relation between stock returns, earnings and cashflows is of importance because it directly addresses the issue of whether accounting data provide value relevant information. The empirical evidence to date, however, has documented low explanatory power for earnings and inconclusive incremental information content for cashflows. This research re-evaluates the incremental information content debate using Australian data. Our research is motivated by: recent innovations in research design, including the specification of nonlinear functional relations between accounting variables and prices, and the fact that differences in firm size characteristics may influence the relative information content of the accounting variables. We observe that: (i) a nonlinear functional relation provides greater explanatory power for both earnings and cashflows;(ii) the results are consistent with more transitory earnings components for smaller firms; and (iii) contrary to received theory, cashflows add greater incremental explanatory power for large firms.     

市盈率隐含的公司创新能力——基于创业板上市公司的实证分析

本文以2010—2018年中国创业板上市公司为研究对象,构建企业创新能力综合评价体系,实证检验市盈率中是否隐含了公司创新能力,结果发现:创新能力具有直接价值相关性,创业板上市公司创新能力正向影响市盈率,在创新投入、创新产出和创新效率三项指标中,创新投入是主要影响因素;创新综合指数正向影响市盈率.机制检验证明了财务绩效、投资者关注在其中发挥了中介作用.进一步地,当公司属于高新技术企业时,创新对市盈率的正向影响更强,但仅在创新投入中存在.本文的研究不仅丰富了创新与企业估值的相关文献,为企业创新能力的衡量提供新思路,同时验证了创新对企业估值定价的驱动作用,为推动企业提高创新能力、助力国家创新驱动发展战略提供理论支撑.     

盈余信息度量、市场反应与投资者框架依赖偏差分析

本文以2 0 0 0年9月到2 0 0 3年1 2月沪市A股3 3 8家上市公司为研究对象,应用实证研究方法,检验以四种不同度量方式表示同一盈余信息所产生的“盈余惯性现象”是否存在差异。结果表明:在三因素模型进行风险调整之前,基于四种盈余信息指标的盈余惯性现象都显著地存在。但经过三因素模型风险调整后,基于“意外盈余率”和“标准化意外盈余率”二个指标的盈余惯性现象消失了;基于“意外盈余”和“标准化意外盈余”二个指标的盈余惯性现象仍然存在,所以买入赢家组合、卖出输家组合仍可获得显著的超常收益。显然,这一研究结果并不支持风险定价学派的观点。笔者认为,根据Tversky和Kahneman( 1 981 )提出的“框架依赖偏差”(FramingDependenceBias)理论,四个盈余信息指标所产生的盈余惯性现象的差异表明我国投资者对盈余信息的反应依赖于信息度量的方式。     

The Value Relevance of Earnings and Nonearnings Information in Regulated and Deregulated Markets: The Case of the Airline Industry

This paper examines the valuation effects of earnings and two nonearnings-based measurements (book values and operating cash flow) on security prices of airline companies under two different market structures: regulated and deregulated. The literature lacks empirical evidence in examining the relative importance of earnings and nonearnings accounting-based measurements in regulated and deregulated markets, especially in the airlines industry. We compare coefficient estimates of regressing stock prices on earnings, book value, and cash flow from operations of airline companies during regulated and deregulated times. A control sample of manufacturing companies is also used for supporting inferences from the airline sample’s findings. In a typical regulated market, using cost recovery plus an adequate rate of return on assets, security prices are highly aligned with nonearnings measurements such as the book value. In the airline industry, regulation took the form of guaranteed routes and subsidies to service rural areas, giving rise to a differential effect of both earnings and nonearnings measurements. Under deregulation, airline firms operate in highly competitive markets with large airline firms enjoying the benefits of economy of scale and service diversification. Thus, the asset capitalization (book value), cash flow, and operational efficiencies (earnings) would be major indicators in the market assessment of the firm’s future profitability and security price. This paper finds that nonearnings measures have higher explanatory power of security prices in regulated times for the airline firms. In deregulated times, although earnings have a stronger relationship with prices, nonearnings measures continued to influence stock price levels, reflecting airline specific economics.

Education and earnings in urban West Africa

Using a series of comparable labor force surveys in urban West Africa, we estimate the private returns to education among representative samples of workers in seven economic capitals (Abidjan, Bamako, Cotonou, Dakar, Lome, Niamey and Ouagadougou). The data allow us to provide a unique cross-country comparison using rigorously the same variables and methodology for each country. We tackle the issues of endogenous sector allocation (public, formal private and informal sectors) and endogeneity of the education variable in the earnings functions. We find that the returns to schooling are most often enhanced once an endogenous education variable is accounted for. This effect holds particularly true in the informal sector. In most West African cities of our sample, the public sector gives more value to education, followed by the formal private sector and then the informal sector. We also shed light on convex returns to education in all the cities and sectors, including in informal activity. More generally, a major contribution of this paper is to provide evidence of significant effects of education on individual earnings in the informal sectors of the West African cities, even at high levels of schooling.
