  • The Economics of Commodity Market Manipulation: a Survey
    The Economics of Commodity Market Manipulation: A Survey Craig Pirrong Bauer College of Business University of Houston February 11, 2017 1 Introduction The subject of market manipulation has bedeviled commodity markets since the dawn of futures trading. Allegations of manipulation have been extremely commonplace, but just what constitutes manipulation, and how charges of manipulation can be proven, have been the subject of intense controversy. The remark of a waggish cotton trader in testimony before a Senate Com- mittee in this regard is revealing: “the word manipulation . initsuse isso broad as to include any operation of the cotton market that does not suit the gentleman who is speaking at the moment.” The Seventh Circuit Court of Appeals echoed this sentiment, though less mordantly, in its decision in the case Cargill v. Hardin: “The methods and techniques of manipulation are limited only by the ingenuity of man.” Concerns about manipulation have driven the regulation of commodity markets: starting with the Grain Fu- tures Act of 1922, United States law has proscribed manipulation, including 1 specifically “corners” and “squeezes.” Exchanges have an affirmative duty to police manipulation, and in the United States, the Commodity Futures Trad- ing Commission and the Department of Justice can, and have exercised, the power to prosecute alleged manipulators. Nonetheless, manipulation does occur. In recent years, there have been allegations that manipulations have occurred in, inter alia, soybeans (1989), copper (1995), gold (2004-2014) nat- ural gas (2006), silver (1998, 2007-2014), refined petroleum products (2008), cocoa (2010), and cotton (2011). Manipulation is therefore both a very old problem, and a continuing one.

Trading Frictions and Market Structure: An Empirical Analysis Abstract Market structure a¤ects the informational and real frictions faced by traders in equity markets. We present evidence which suggests that while real fric- tions associated with the costs of supplying immediacy are less in order driven systems, informational frictions resulting from increased adverse selection risk are considerably higher in these markets. Firm value, transaction size and order location are all major determinants of the trading costs faced by investors. Consistent with the stealth trading hypothesis of Barclay and Warner (1993), we report that informational frictions are at their highest for small trades which go through the order book. Finally, while there is no doubt that the total costs of trading on order-driven systems are lower for very liquid securities, the inherent informational ine¢ ciencies of the format should be not be ignored. This is particularly true for the vast majority of small to mid-size stocks that experience infrequent trading and low transac- tion volume. JEL Classi…cation: G12; G14; D23; L22.

The resulting lack of limit orders can cause notable price impact for market orders. It is crucial for the market players to know the duration of the correction and the possible long term effects of this kind of shocks. Based on the literature, we build up a vector autoregressive model to quantify the duration of the correction of market liquidity and explore the size of the critical market orders which drives to market shocks.

Research Article REGULATORY FRAMEWORK OF PRE AND POST TRADING TRANSPARENCY IN THE TEHRAN STOCK EXCHANGE Hosein Hasanzadeh Sarvestani1, Seeyd Abbas Moosavian2 and Hashem Nikoumaram3 1Department of Financial Management, Science and Research Branch, Islamic Azad University, Tehran, Iran 2Islamic Research Institute for Culture and Thought, Qom, Iran 3Science and Research Branch, Islamic Azad University, Tehran, Iran *Author for Correspondence ABSTRACT Information in securities markets plays central role. The issue of market transparency refers to the clarity with which market participants (and the public at large) can perceive the process of securities trading. In addition to helping investors make better decisions, transparency increases confidence in the fairness of the markets. Thus, regulators should aim to ensure that markets are fair, efficient and transparent and investors are given fair access to market information. In this study, we categorize portions of rules and regulations that were relevant to market transparency and after difining the association between the main categories; we present a regulatory framework for pre-post trading transparency. The main categories of regulatory framework are the dissemination of pre and post transactions information, prohibition of inside information abuse, prohibition of market manipulation, recording, maintenance and reporting documents and information by financial institutions, exchanges and self-regulatory organization, trader's information about procedures and regulation of stocks trading and violations and punishments. We explain the effects of these categories on the market transparency and conclude that the regulatory framework can be used by researchers and SEO for future researches and weaknesses amendment.

The statistical population of this study includes all of the companies listed in Tehran Stock Exchange. Using simple random sampling, 469 companies have been selected among the companies listed in the stock exchange and they were analyzed during the time period of 2009-2012. The collected data was analyzed using Wilcoxon test and Spss software version 19 and according to the results, there is a negative significant relationship between the indicators of liquidity (trading volume and price volatility and market depth) and trading halt. This means that these variables are reduced by applying trading halt. The Bid-Ask spread index is related negatively and directly to trading halt. This indicates that the value of this variable is increased by applying a trading halt. Therefore it can be concluded that trading halt is not an efficient mechanism in Tehran Stock Exchange.

  • Algorithmic Trading Strategies
    CSP050 MAY 2020 Algorithmic Trading Strategies ANZHELIKA ISHKHANYAN AND ASHER TRANGLE Memorandum TO: Special Counsel, CFTC Division of Market Oversight FROM: Director, CFTC Division of Market Oversight RE: Algorithmic Trading and Regulation Automated Trading DATE: January 9, 2020 Welcome to DMO. I’m confident that you’ll find the position a challenging one, and I’ve already got a meaty topic to get you started on. I recently received an email from the Chairman expressing his concerns regarding the negative effects of algorithmic trading on financial markets. The Chairman is convinced that the CFTC should have direct access to trading systems’ source code to prevent potential market abuses with systemic implications. To that end, the Chairman proposes we reconsider Regulation Automated Trading (“Regulation AT”) which would require all traders using algorithms to register with the CFTC and would give CFTC direct and unfettered access to their source code. Please find attached the Chairman’s email which outlines his priorities and main concerns pertaining to algorithmic trading. In addition, I have sketched out my own reactions to reconsidering Regulation AT in an informal memo, attached as Appendix I. In addition, you may find it useful to refer to a legal intern’s memoranda, attached as Appendix II, which offers a brief overview of Regulation AT, its history, and a short discussion of other regulators’ efforts to address algorithmic trading. After considering these materials, please come and brief me on the following questions: ● What, precisely, are the public policy challenges posed by the emergence of algorithmic trading, and does this practice pose any serious problems to U.S.
