This study examines the effect of media coverage on investor reaction in the Swiss stock market. Following corporate publications, the performance of stocks listed in the Swiss Market Index is analysed with regard to the amount of re-releases in relevant media channels. It is shown that abnormal returns are positively related to media coverage. This holds true for stocks listed in the SMI and for other large and mid cap SPI stocks. The relationship is according to the analysed data stronger for positive abnormal returns.

Download Social Media and Stock Market Participation Book in PDF, ePub and Kindle
We investigate the effect of social media adoption on stock market participation in the United States. Using plausibly exogenous variation in the early adoption of Twitter across counties, we show that a 10% increase in social media usage is associated with a 2.5% higher rate of stock ownership and an overall increase in stock market wealth. Consistent with the notion of social media as an information channel, we find greater effects in counties with lower levels of pre-existing stock market knowledge and a decline in the number of financial advisors. Twitter adoption also fuels interest in "meme stocks," which tend to be more volatile and owned by retail investors. Overall, our results suggest a substantial impact of modern information technology on financial markets.

In recent years there has been a great influx of sources for business and financial news, yet the hope that this financial media boom would lead to the democratization of the financial markets has not been realized. Thomas Schuster's The Markets and the Media explores why the expansion of economic communication has proven to be of only limited benefit, arguing that the financial media boom has had negative repercussions resulting in substantial costs for the individual as well as the systemic level.

Download The Value of Social Media for Predicting Stock Returns Book in PDF, ePub and Kindle
Michael Nofer examines whether and to what extent Social Media can be used to predict stock returns. Market-relevant information is available on various platforms on the Internet, which largely consist of user generated content. For instance, emotions can be extracted in order to identify the investors' risk appetite and in turn the willingness to invest in stocks. Discussion forums also provide an opportunity to identify opinions on certain companies. Taking Social Media platforms as examples, the author examines the forecasting quality of user generated content on the Internet.

Download Corporate Payout Policy Book in PDF, ePub and Kindle
Corporate Payout Policy synthesizes the academic research on payout policy and explains "how much, when, and how". That is (i) the overall value of payouts over the life of the enterprise, (ii) the time profile of a firm's payouts across periods, and (iii) the form of those payouts. The authors conclude that today's theory does a good job of explaining the general features of corporate payout policies, but some important gaps remain. So while our emphasis is to clarify "what we know" about payout policy, the authors also identify a number of interesting unresolved questions for future research. Corporate Payout Policy discusses potential influences on corporate payout policy including managerial use of payouts to signal future earnings to outside investors, individuals' behavioral biases that lead to sentiment-based demands for distributions, the desire of large block stockholders to maintain corporate control, and personal tax incentives to defer payouts. The authors highlight four important "carry-away" points: the literature's focus on whether repurchases will (or should) drive out dividends is misplaced because it implicitly assumes that a single payout vehicle is optimal; extant empirical evidence is strongly incompatible with the notion that the primary purpose of dividends is to signal managers' views of future earnings to outside investors; over-confidence on the part of managers is potentially a first-order determinant of payout policy because it induces them to over-retain resources to invest in dubious projects and so behavioral biases may, in fact, turn out to be more important than agency costs in explaining why investors pressure firms to accelerate payouts; the influence of controlling stockholders on payout policy --- particularly in non-U.S. firms, where controlling stockholders are common --- is a promising area for future research. Corporate Payout Policy is required reading for both researchers and practitioners interested in understanding this central topic in corporate finance and governance.

Download Media and Google Book in PDF, ePub and Kindle
Media news is a proxy for attention from the information supply side, and the Google search is a proxy for attention from the information demand side. I show that that the attention has the biggest impact on financial markets when the supply side attention and demand side attention move in the same direction. A portfolio of buying stocks with both attentions up and short-selling stocks with both down generates 17% annual abnormal returns. The finding indicates that media is important to financial market only when the investors are willing to be affected. Furthermore, the attention measure is less subject to the estimation bias.

Download Natural Language Processing for Social Media Book in PDF, ePub and Kindle
In recent years, online social networking has revolutionized interpersonal communication. The newer research on language analysis in social media has been increasingly focusing on the latter's impact on our daily lives, both on a personal and a professional level. Natural language processing (NLP) is one of the most promising avenues for social media data processing. It is a scientific challenge to develop powerful methods and algorithms which extract relevant information from a large volume of data coming from multiple sources and languages in various formats or in free form. We discuss the challenges in analyzing social media texts in contrast with traditional documents. Research methods in information extraction, automatic categorization and clustering, automatic summarization and indexing, and statistical machine translation need to be adapted to a new kind of data. This book reviews the current research on NLP tools and methods for processing the non-traditional information from social media data that is available in large amounts (big data), and shows how innovative NLP approaches can integrate appropriate linguistic information in various fields such as social media monitoring, healthcare, business intelligence, industry, marketing, and security and defence. We review the existing evaluation metrics for NLP and social media applications, and the new efforts in evaluation campaigns or shared tasks on new datasets collected from social media. Such tasks are organized by the Association for Computational Linguistics (such as SemEval tasks) or by the National Institute of Standards and Technology via the Text REtrieval Conference (TREC) and the Text Analysis Conference (TAC). In the concluding chapter, we discuss the importance of this dynamic discipline and its great potential for NLP in the coming decade, in the context of changes in mobile technology, cloud computing, virtual reality, and social networking. In this second edition, we have added information about recent progress in the tasks and applications presented in the first edition. We discuss new methods and their results. The number of research projects and publications that use social media data is constantly increasing due to continuously growing amounts of social media data and the need to automatically process them. We have added 85 new references to the more than 300 references from the first edition. Besides updating each section, we have added a new application (digital marketing) to the section on media monitoring and we have augmented the section on healthcare applications with an extended discussion of recent research on detecting signs of mental illness from social media.

Download Uncertainty Strengthens the Effects of Media Sentiment in the Stock Market Book in PDF, ePub and Kindle
In this paper, I analyse whether the level of uncertainty in the financial markets affects the previously demonstrated relationship between media sentiment and stock market outcomes. I capture media sentiment by analysing the tone of the textual data from the New York Times stock market column “Financial Markets” from 1927-2020. Uncertainty is measured on a daily level by a proven approach of computing the magnitude of unpredictability about the future. I find evidence that the level of uncertainty indeed matters for the strength of the effect on stock market outcomes. For example, a one standard deviation increase in the media sentiment under high uncertainty predicts a change in DJIA returns that is 4-5 times stronger than under low uncertainty. Furthermore, there is some indication that the additional effect through uncertainty is more robust for small stocks and that it also affects the relationship between media sentiment and NYSE trading volume.
