Limitations and directions for future research
In terms of limitations, the present paper refers to the EMH and considers that investors are able to predict the effect of the launching of a Twitter platform on future cash flows of the firm and firm value. However, the adoption of a new marketing strategy by a firm is more likely to affect its intangible assets, i.e. brand equity and customer loyalty, which might result in long-term value creation. Moreover, all investors are not experts in marketing developments and in social media strategies. As such, they may not perfectly and accurately evaluate the association between launching a social media platform and future cash flows (Srinivasan and Hanssens, 2009). Also, investors might be subject to hyping and as a result exhibit irrational behavior or exaggerated reaction in response to specific marketing developments (Sirri and Tufano, 1998). Thus, future work should examine the long-term association between social media activities and both operating and market performance.
Another interesting area of future research is the study of the effect on performance of strategic social interaction choices. Interactivity is a multi-faceted concept that goes beyond our definition of two-way communication to further include a high level of user engagement, and timeliness of communication (Liu and Shrum, 2002). A more detailed analysis of the content of posted comments, their frequency and timeliness would add to our understanding on the effect of interactivity on firm performance. Another area of research is to follow those firms that started with one-way messaging and that shifted to two-way communication, and study the causes and consequences of such a strategic change on firm performance.
