Social media can help investors gather and share information about stock markets. However, it also presents opportunities for fraudsters to spread false or misleading statements in the marketplace. Analyzing millions of messages sent on the social media platform Twitter about small capitalization firms, we find that an abnormally high message activity on social media is associated with a large price increase on the event day and followed by a sharp price reversal over the next week. Our findings are consistent with the patterns of a pump-and-dump scheme, where fraudsters use social media to temporarily inflate the price of small capitalization stocks. To differentiate between the effects of overoptimism by noise traders and the illegal gains of a pump-and-dump scheme, we investigate social interactions between Twitter users through the use of network theory. We identify several clusters of users with suspicious online activity (stock promoters, fake accounts, automatic postings), favoring the manipulation/promotion hypothesis over the behavioral hypothesis.

Markets face a new and daunting mode of manipulation. With this new mode of market manipulation, millions of dollars can vanish in seconds, rogue actors can halt the trading of billion-dollar companies, and trillion-dollar financial markets can be distorted with a simple click or a few lines of code. Every investor and institution is at risk. This is the new precarious reality of our financial markets.This Article is about our ominous financial reality, this dangerous new mode of market manipulation, and the need for pragmatic policies to better address the rising threats to manipulate our financial markets. To start, the Article offers an overview about the recent rise and regulation of new financial technology. It begins with a close examination of The Flash Crash of 2010 and the publication of Flash Boys by Michael Lewis. Next, the Article surveys the changing landscape of market manipulation. It identifies traditional manipulation methods like cornering, front running, and pumping-and-dumping, as well as new manipulation methods like spoofing, pinging, and mass misinformation. It explains how new cybernetic market manipulation schemes that leverage modern technologies like electronic networks, social media, and artificial intelligence are more harmful than traditional schemes. The Article then grapples with why this new mode of market manipulation will present critical challenges for regulators. Finally, it recommends three pragmatic proposals for combating the new threats of cybernetic market manipulation by improving intermediary integrity, enhancing financial cybersecurity, and simplifying investment strategies. Ultimately, this Article provides an original and improved framework for thinking and acting anew about market regulation, market operations, and market manipulation.

Over the years, a plethora of reports has emerged that assess the causes, dynamics, and effects of cyber threats. This proliferation of reports is an important sign of the increasing prominence of cyber attacks for organizations, both public and private, and citizens all over the world. In addition, cyber attacks are drawing more and more attention in the media. Such efforts can help to better awareness and understanding of cyber threats and pave the way to improved prevention, mitigation, and resilience. This report aims to help in this task by assessing what we know about cyber security threats based on a review of 70 studies published by public authorities, companies, and research organizations from about 15 countries over the last few years. It answers the following questions: what do we know about the number, origin, and impact of cyber attacks? What are the current and emerging cyber security trends? And how well are we prepared to face these threats?

This paper discusses the impact of the rapid adoption of artificial intelligence (AI) and machine learning (ML) in the financial sector. It highlights the benefits these technologies bring in terms of financial deepening and efficiency, while raising concerns about its potential in widening the digital divide between advanced and developing economies. The paper advances the discussion on the impact of this technology by distilling and categorizing the unique risks that it could pose to the integrity and stability of the financial system, policy challenges, and potential regulatory approaches. The evolving nature of this technology and its application in finance means that the full extent of its strengths and weaknesses is yet to be fully understood. Given the risk of unexpected pitfalls, countries will need to strengthen prudential oversight.

Market manipulation comes in many forms. For a wrong that some say started life with groups of men dressed in Bourbon uniforms spreading false information in cod French accents, the speed of change has accelerated dramatically in the modern era, via the Internet, novel forms of electronic communication, ultra-fast computer-generated trading, new types of financial instruments, and increased globalisation. This means that opportunities for carrying-out new forms of manipulation now exist on an exponential scale. Looks at the mechanisms, criminal and civil, to confront market manipulation, its enforcement regimes, legal and evidential rules and potential loopholes. Shows how every individual involved in market transactions can fall foul of the law if they do not ensure integrity in their dealings. The ‘tricks’ used by those seeking to benefit from this special category of fraud and the relationship of dedicated provisions to the general law is outlined, with key statutory provisions set out in an appendix. A valuable accompaniment to The Little Book of Insider Dealing (Waterside Press, 2018). An invaluable pocket guide and law primer. An essential guide for investors. With practical examples and decided cases. An up-to-date treatment of a fast-moving topic. Describes both criminal and regulatory regimes. Contents include Forms of Market Manipulation; Suspicion, Identification, Detection and Investigation; Obligations and Enforcement; Criminal Offences, Defences and Punishment; Regulatory Provisions and Penalties; Evidence; Acronyms; Select Bibliography; Key Statutory Provisions and Index.

The U.S. stock market has been transformed over the last twenty-five years. Once a market in which human beings traded at human speeds, it is now an electronic market pervaded by algorithmic trading, conducted at speeds nearing that of light. High-frequency traders participate in a large portion of all transactions, and a significant minority of all trade occurs on alternative trading systems known as “dark pools.” These developments have been widely criticized, but there is no consensus on the best regulatory response to these dramatic changes. The New Stock Market offers a comprehensive new look at how these markets work, how they fail, and how they should be regulated. Merritt B. Fox, Lawrence R. Glosten, and Gabriel V. Rauterberg describe stock markets’ institutions and regulatory architecture. They draw on the informational paradigm of microstructure economics to highlight the crucial role of information asymmetries and adverse selection in explaining market behavior, while examining a wide variety of developments in market practices and participants. The result is a compelling account of the stock market’s regulatory framework, fundamental institutions, and economic dynamics, combined with an assessment of its various controversies. The New Stock Market covers a wide range of issues including the practices of high-frequency traders, insider trading, manipulation, short selling, broker-dealer practices, and trading venue fees and rebates. The book illuminates both the existing regulatory structure of our equity trading markets and how we can improve it.
