摘要

我们描述了在全球相互关联的市场中预测收益的挑战,并记录了在共识和个人预测水平上对外国风险敞口和预期国家GDP增长信息的低效使用。一个国家与美国的距离,对公司的重要性,可见度,以及有关外国风险敞口的更精确信息的可用性,有助于共识预测的效率。我们确定了分析师个人全球专业知识的一个维度——公司与分析师投资组合中其他公司之间的相似性——并表明它有助于预测效率、准确性和信息量,并有助于分析师达到令人垂涎的全明星级别,这表明全球化不仅构成了挑战,也为研究提供商和分析师创造了一个脱颖而出的机会。

Global Expertise of Financial Analysts
We describe the challenges of forecasting earnings in a globally interconnected marketplace, and we document inefficient use of information regarding foreign country exposures and expected country GDP growth at the consensus and individual forecast levels. A country’s proximity to the US, importance to the firm, and visibility, as well as availability of more precise information about foreign country exposures, contribute to consensus forecast efficiency. We identify a dimension of individual analyst global expertise — similarity in exposure between the firm and the rest of the firms in the analyst portfolio — and show that it contributes to forecast efficiency, accuracy, and informativeness and that it helps the analyst achieve the coveted all-star rank, suggesting that globalization not only poses a challenge but also creates an opportunity for research providers and analysts to distinguish themselves.
