摘要
目的自 2022 年 2 月以来,乌克兰与俄罗斯之间的冲突对全球金融市场产生了重大影响,改变了投资者的行为,加剧了市场波动。西方国家对俄罗斯的制裁影响了市场的不确定性。学术文献深入研究了市场对冲突的反应,并展示了各种不同的影响。我们的研究深入探讨了企业在冲突期间留在或退出俄罗斯的决策如何影响分析师的情绪。设计/方法/途径利用来自 Eikon、Refinitiv 的分析师修正分数(ARS)数据,我们的分析强调了分析师在不确定时期的重要性(Kacperczyk 和 Seru,2007 年;Loh 和 Stulz,2018 年)。利用静态和动态面板分析,我们在控制关键变量的同时,研究了俄罗斯风险敞口对 ARS 的影响。研究结果在俄罗斯保留业务的公司往往会提高 ARS 的整体得分,从而促使分析师对相关公司的预测更加乐观。控制 ARS 的内生性和潜在动态并不会改变主要研究结果。总之,研究结果证实,在冲突开始后,宣布继续留在俄罗斯或离开俄罗斯的公司的回报没有受到影响(Balyuk 和 Fedyk,2023 年)。
Does remaining in Russia affect analysts’ sentiment?
Purpose
Since February 2022, the conflict between Ukraine and Russia has significantly influenced global financial markets, altering investor behavior and increasing market volatility. Western countries’ sanctions on Russia have influenced market uncertainty. Academic literature has deeply investigated the market’s reaction to the conflict and demonstrated a diverse range of impacts. Our study delves into how corporate decisions to remain in or exit Russia during the conflict influence analyst sentiment.
Design/methodology/approach
Leveraging data on analysts' revision scores (ARS) from Eikon, Refinitiv, our analysis underscores the importance of analysts during periods of uncertainty (Kacperczyk and Seru, 2007; Loh and Stulz, 2018). Using static and dynamic panel analysis, we examine the impact of Russia exposure on ARS while controlling for key variables.
Findings
Companies that retain a presence in Russia tend to enhance the overall ARS score, contributing to increased optimism among analysts regarding forecasts for the firms in question. Controlling for endogeneity and underlying dynamics in ARS does not alter the main findings. All in all, the results confirm the absence of an impact on the companies' returns post-announcement to continue or leave Russia after the start of the conflict (Balyuk and Fedyk, 2023).
Originality/value
This research sheds light on the complex relationship between geopolitical events, corporate decisions and investor sentiment, offering valuable insights for stakeholders, policymakers and regulators.
