How Do Social Media Affect Analyst Stock Recommendations? Evidence from S&P 500 Electric Power Companies' Twitter Accounts

Abstract

Research summary: The importance of firm‐stakeholder relationships is gaining increasing attention. Although a theory of the drivers and consequences of stakeholder pressure has been developing, it focuses on pressures from organized stakeholders such as shareholders, NGOs, and activists, and does not incorporate the emerging possibility that individual voices may matter. By exploring corporate Twitter, which facilitates movement of individual stakeholders such as customers to a higher stakeholder class by providing them with a greater sense of power and urgency, we study the circumstances under which customer voices significantly affect analyst stock recommendations. We find that favorable reactions to firm‐initiated messages matter, directly or indirectly, depending on the messages' growth implications. Customer‐initiated negative messages have a significant impact only with high volume and formal institutions that support customer opinions. Managerial summary: Social media is increasingly used by firms for disclosing information and engaging stakeholders. Yet, we know little about whether and how social media usage matters. We show how corporate Twitter usage may influence analyst stock recommendations. Our interviews of securities analysts suggest that social media is not institutionalized yet, but increasingly used as a source of channel checks, especially for vibes, validations, and so on. Our analyses of corporate Twitter accounts show that both firm‐initiated and customer‐initiated tweets can have significant impact on analyst recommendations under certain conditions. For firm‐initiated tweets, the extent of retweets is an important factor, along with the content of tweets, in particular, growth implications. For customer‐initiated tweets, negative tweets matter, but only with high volume and regulatory structure that supports customer protection. Copyright © 2017 John Wiley & Sons, Ltd.

From buzz to bucks: The impact of social media opinions on the locus of innovation

“…On the one hand, an increase in positive opinions can build these investors' confidence. On the other hand, investors may become unnerved by the emergence of negative or critical UGC toward the focal firms, resulting in financial losses (Kim and Youm 2017). Second, the majority of A-shares are issued by state-owned enterprises in China, which have struggled to reform and thus align with the transformation of China's economy (Jefferson 2016).…”

“…The primary reason for our focus on listed firms is that such firms are closely tied to the users who contribute to social media UGC. In particular, compared to those of private firms, the operations and performances of listed firms hinge much more heavily on public voices because such opinions significantly influence individual investors' and consumers' attitudes toward the firms (Kim and Youm 2017). In this regard, listed firms are keener than private firms to effectively manage UGC on social media, as doing so can help them enact relevant strategies and improve their performance.…”

Investor Sentiment, Innovation Investment and Cash Dividend

“…Product or service innovation is crucial to achieving the transformation goal of an economy (Kim & Youm, 2017). In order to empirically ascertain the relationship between corporate innovation investment and investor sentiment, data was collected from different sources.…”

Uso corporativo de mídias sociais e o desempenho de mercado

“…A adoção das mídias sociais na sociedade tem levado as organizações a adotarem ferramentas tecnológicas para divulgar e comunicar informações organizacionais importantes às partes interessadas na organização (Smits & Mogos, 2013;Kim & Youm, 2017). Segundo Lee, Hutton e Shu (2015), elas se tornaram um canal viável para divulgação de informações importantes, quando comparadas aos canais tradicionais de informação, possuem maior alcance e permitem que as empresas enviem de forma direta e com rapidez a mensagem pretendida.…”

“…O estudo se justifica pela importância em compreender o comportamento das empresas no ambiente de mídias sociais e a forma como estas influenciam os participantes do mercado e afetam o valor da empresa (Jung, Naughton, Tahoun, & Wang, 2018;Kim & Youm, 2017, Zhang, 2015. A mídia social têm sido uma nova vertente importante da literatura, dada a sua crescente utilização pela sociedade e o potencial para os usuários criarem e disseminarem seu próprio conteúdo sobre as empresas.…”
