We study fake news in financial markets using a novel dataset from an undercover SEC investigation. Our setting measures both the direct and indirect effects of market manipulation. Fake articles directly induce abnormal trading activity and increase price volatility, but in addition, the awareness of fake news from the SEC investigation indirectly affects legitimate articles, causing market participants to discount all news from these platforms. These spillover consequences significantly reduce the social network's impact on information dissemination, trading, and prices. The results are particularly acute among small firms with high retail ownership and for the most circulated articles. The equilibrium response of consumers and producers of news on these networks is consistent with models of trust, providing novel evidence on the importance of social capital for financial activity.

There are a few things that the United States prides itself on: liberty, democracy, and a free market system. Since its inception, the financial market has defined the financial market has defined the United States' position as a global leader. Therefore, balancing issues involving both the First Amendment and the free market system can be complex. On April 10, 2017, the Securities Exchange Commission ("SEC") filed twenty-seven complaints for fraudulent promotion of stock against stock promotion firms and holding companies. The holding companies paid writers to generate hundreds of optimistic articles about public company clients while concealing from investors that these were paid promotions. Out of the twenty-seven complaints, one company, Lidingo Holdings LLC ("Lidingo Holdings"), has garnered the most publicity. Beginning in 2010, Lidingo Holdings allegedly disseminated fake or hyperbolic information about stock options to either inflate or denigrate buyers' interest. The SEC mandates that stock promoters disclose their relationship with holding companies. Failure to disclose leads stockholders to believe the source was an independent researcher. This is where the First Amendment intersects with the financial markets. This Comment will focus on how market manipulation and the First Amendment could affect how the U.S. District Court for the Southern District of New York will decide SEC v. Lidingo Holdings, LLC "fake news" case. Section II will provide a primer of the history and evolution of market manipulation schemes, describe the SEC and its regulatory powers, look at the historical strength of the First Amendment, and introduce cases that can be used as precedent going forward. Section III will analyze prior cases and apply those rulings to Lidingo Holdings, to argue that the SEC should use a similar justification that the Federal Trade Commission ("FTC") uses for disseminating harmful commercial speech. Finally, Section IV will recommend that the court find the speech in Lidingo Holdings constitutes commercial speech, and further, that the SEC should implement a whistleblower program to regulate fake news, as well as follow the FTC's enforcement actions when dealing with fake news in the commercial speech context.

Does fake news in financial markets attract more investor attention and have a significant impact on stock prices? We use the SEC crackdown of stock promotion schemes in April 2017 to examine investor attention and the stock price reaction to fake news articles. Using data from Seeking Alpha, we find that fake news stories generate significantly more attention than a control sample of legitimate articles. We find no evidence that article commenters can detect fake news and Seeking Alpha editors have only modest ability to detect fake news. However, we show that machine learning algorithms can successfully identify fake news from linguistic features of the article. The stock market appears to price fake news correctly. While abnormal trading volume increases around the release of fake news, the increase is less than that observed for legitimate news. The stock price reaction to fake news is discounted when compared to legitimate news articles.

A guide to curbing monopoly power in stock markets Engaging and informative, Regulating Competition in Stock Markets skillfully analyzes the impact of the recent global financial crisis on health and happiness, and uses this opportunity to put regulatory systems in perspective. Happiness is lost because of emotional and physical health deterioration resulting from the crisis. Therefore, the authors conclude that financial crisis prevention should be the focus of public policy. This book is the most comprehensive study so far on potential risks to the stock market, especially various forms of market manipulation that lead to mania and eventual crisis. Based on litigation cases from international stock markets, and borrowing multidisciplinary findings in the fields of finance, economics, accounting, media studies, criminology, legal studies, psychology, and medicine, this book is the first to provide thorough micro-level regulatory proposals rooted in financial reality. By focusing on securities trading, they apply antitrust measures to limiting monopolistic power that is used for the manipulation of investors' perception and monopolistic profit. These proposals are quantifiable, adjustable, inexpensive, and can be easily implemented by any securities regulating agency for real-time oversight and daily operations. The recommendations found here are intended to improve the fairness and transparency of the financial markets, thereby perfecting the market competition, protecting investors, stabilizing the market, and preventing crises Explores how avoiding crises can to contribute to a more scientific, health aware, and civilized economic and social development Written by a team of authors who have extensive experience in this dynamic field, including Nobel Laureate Lawrence R. Klein Since the founding of the first, organized stock exchange in Amsterdam 400 years ago, no systematic economic research results on stock markets have been implemented in stock market regulation around the world. Regulating Competition in Stock Markets aims to fill this void.

This book is divided into two parts, the first of which describes AI as we know it today, in particular the Fintech-related applications. In turn, the second part explores AI models in financial markets: both regarding applications that are already available (e.g. the blockchain supply chain, learning through big data, understanding natural language, or the valuation of complex bonds) and more futuristic solutions (e.g. models based on artificial agents that interact by buying and selling stocks within simulated worlds). The effects of the COVID-19 pandemic are starting to show their financial effects: more companies in a liquidity crisis; more unstable debt positions; and more loans from international institutions for states and large companies. At the same time, we are witnessing a growth of AI technologies in all fields, from the production of goods and services, to the management of socio-economic infrastructures: in medicine, communications, education, and security. The question then becomes: could we imagine integrating AI technologies into the financial markets, in order to improve their performance? And not just limited to using AI to improve performance in high-frequency trading or in the study of trends. Could we imagine AI technologies that make financial markets safer, more stable, and more comprehensible? The book explores these questions, pursuing an approach closely linked to real-world applications. The book is intended for three main categories of readers: (1) management-level employees of companies operating in the financial markets, banks, insurance operators, portfolio managers, brokers, risk assessors, investment managers, and debt managers; (2) policymakers and regulators for financial markets, from government technicians to politicians; and (3) readers curious about technology, both for professional and private purposes, as well as those involved in innovation and research in the private and public spheres.

The book provides deep insight into theoretical and empirical evidence on information and communication technologies (ICT) as an important factor affecting financial markets. It is focused on the impact of ICT on stock markets, bond markets, and other categories of financial markets, with the additional focus on the linked FinTech services and financial institutions. Financial markets shaped by the adoption of the new technologies are labeled ‘digital financial markets’. With a wide-ranging perspective at both the local and global levels from countries at varying degrees of economic development, this book addresses an important gap in the extant literature concerning the role of ICT in the financial markets. The consequences of these processes had until now rarely been considered in a broader economic and social context, particularly when the impact of FinTech services on financial markets is taken into account. The book’s theoretical discussions, empirical evidence and compilation of different views and perspectives make it a valuable and complex reference work. The principal audience of the book will be scholars in the fields of finance and economics. The book also targets professionals in the financial industry who are directly or indirectly linked to the new technologies on the financial markets, in particular various types of FinTech services. Chapters 2, 5 and 10 of this book are available for free in PDF format as Open Access from the individual product page at www.routledge.com.
