We have investigated which topics are on the minds of stock microbloggers. We have classified thousands of tweets into the following news or event categories: Corporate Governance, Financial Issues, Operations, Restructuring Issues, Legal Issues, and Technical Trading. In addition, to allow for more granular analysis, we have defined subcategories for which we found a substantial number of messages among our data set (e.g., stock-related vs. market-related technical trading signals).
The table below provides an overview of the event categories and sample messages assigned to the respective class. It shows that technical trading signals are the most frequently mentioned event category with references in almost one third of all messages (34.0%), among which stock-related signals make up the vast majority (28.2%). Next are comments regarding company operations (20.3%), especially product development (9.4%), operational performance (4.2%) and marketing (4.2%). Financial issues come third as an event category (13.3%) with a majority of messages dedicated to the discussion of earnings results (6.9%). Restructuring issues (6.1%), Legal Issues (3.5%) and topics related to Corporate Governance (3.3%) are mentioned less frequently. The distribution of topics shows some interesting differences to professionally edited newspapers and confirms that stock microblogs provide information "off the beaten track".
