Book Description
Previous research and recent statements by the Securities and Exchange Commission indicate that e-mail spam and message board posts are often used to manipulate markets in a variation of the classical pump-and-dump scheme, leading to temporary market reactions followed by price reversals. In contrast, I hypothesize that financial blogs spread genuine information leading to permanent market adjustments.I investigate stock recommendations on blogs and find that bloggers tend to write about liquid securities issued by large firms; I also find that bloggers offer short advice consistent with momentum strategies but long advice consistent with contrarian strategies.To test the hypothesis that stock recommendations on blogs impact both prices and trading volumes of the touted securities, I collect recommendations from blogs and analyze returns and trading volumes on the days surrounding publication; I offer evidence to support my hypothesis and I find some evidence of market reaction being stronger for short recommendations. I hypothesize and test that the magnitude of the market reaction depends on the market capitalization of the touted firm, on the size of the blog's audience, on the depth of the analysis of the blog post and on the perceived skill of the blog's author. I find that the market appears to react more strongly to recommendations given by holders of a graduate degree in Finance or Economics; the other hypothesized factors do not have an impact on the magnitude of the reaction. Finally, I document the absence of price reversals in the twenty days following blog publication, giving support to the hypothesis that blogs offer genuine information.

Book Description
In four empirical studies, this cumulative work provides valuable insights for marketing executives of statutory health insurance funds and social media responsible. Paper I and II provide evidence about the importance and interplay of price and corporate reputation on the market of statutory health insurance. The second part changes perspective to corporate communication issues in the social media environment. By introducing the “social media brand value chain” paper III conducts a literature review of state of the art social media research. By means of a field experiment on Facebook, paper IV shows that brands do not necessarily have to communicate via their brand fan pages in a highly interactive and vivid way to positively influence attitudinal measures among their fan base.

Book Description
In his debut book on trading psychology, Inside the Investor’s Brain, Richard Peterson demonstrated how managing emotions helps top investors outperform. Now, in Trading on Sentiment, he takes you inside the science of crowd psychology and demonstrates that not only do price patterns exist, but the most predictable ones are rooted in our shared human nature. Peterson’s team developed text analysis engines to mine data - topics, beliefs, and emotions - from social media. Based on that data, they put together a market-neutral social media-based hedge fund that beat the S&P 500 by more than twenty-four percent—through the 2008 financial crisis. In this groundbreaking guide, he shows you how they did it and why it worked. Applying algorithms to social media data opened up an unprecedented world of insight into the elusive patterns of investor sentiment driving repeating market moves. Inside, you gain a privileged look at the media content that moves investors, along with time-tested techniques to make the smart moves—even when it doesn’t feel right. This book digs underneath technicals and fundamentals to explain the primary mover of market prices - the global information flow and how investors react to it. It provides the expert guidance you need to develop a competitive edge, manage risk, and overcome our sometimes-flawed human nature. Learn how traders are using sentiment analysis and statistical tools to extract value from media data in order to: Foresee important price moves using an understanding of how investors process news. Make more profitable investment decisions by identifying when prices are trending, when trends are turning, and when sharp market moves are likely to reverse. Use media sentiment to improve value and momentum investing returns. Avoid the pitfalls of unique price patterns found in commodities, currencies, and during speculative bubbles Trading on Sentiment deepens your understanding of markets and supplies you with the tools and techniques to beat global markets— whether they’re going up, down, or sideways.

Book Description
The growing number of user-generated content that can be found online has led to a huge amount of data that can be used for scientific research. This book investigates the prediction of certain human-related events using valences and emotions expressed in user-generated content with regard to past and current research. First, the theoretical framework of user-generated content and sentiment detection- and classification methods is explained, before empirical literature is categorized into three specific prediction subjects. This is followed by a comprehensive analysis including a comparison of prediction methods, consistency, and limitations with respect to each of the three predictive sources.
