Download or read book Does Insider Trading Raise Market Volatility written by Mr.Julan Du and published by International Monetary Fund. This book was released on 2003-03-01 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the role of insider trading in explaining cross-country differences in stock market volatility. The central finding is that countries with more prevalent insider trading have more volatile stock markets, even after one controls for liquidity/maturity of the market and the volatility of the underlying fundamentals (volatility of real output and of monetary and fiscal policies). Moreover, the effect of insider trading is quantitively significant when compared with the effect of economic fundamentals.
Download or read book Is the Increase in Insider Information Confusing the Markets written by Jodie Wade McGaughey and published by . This book was released on 2015 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: "To combat the asymmetry between insider information and investor information, the Sarbanes-Oxley Act of 2002 (SOX) (2006) introduced a full disclosure regulation requiring more frequent insider voluntary earnings disclosures. Managers issue Securities and Exchange Commission 8-K filings to comply with Reg. FD and SOX requirements. Regulatory compliance requirements cause managers to release much more frequent 8-K voluntary earnings disclosures (VEDs). Managers can potentially use VEDs to create volatility for their own and institutional shareholders benefits (Das, Shroff, & Zhang, 2009; Gu & Li, 2007). This study examines the market volatility surrounding VEDs. The study determines if managers self-servingly use VEDs to attract institutional investors. The study also demonstrates managers can use VEDs to create periods of arbitrage. The study examines for arbitrage, since arbitrage theories support the price mean reversion theory of price predictability and the behavioral finance theories of investor over-reliance on insider information, investor momentum, investor habits, and quantitative trading. The study uses the directional move index to measure market volatility and the percentage of transient institutional investors (TII) ownership to measure TII attractiveness. In the study, the days around the VED represent an event period. The study uses the event study method to measure the difference between the directional move indexes (DMI) during the event periods versus the same indices for the non-event periods leading up to the events. The study also uses the DMI as a standalone event without comparison to non-event periods. The study regresses the number of VEDs in a quarter against the DMI to measure if the VEDs predict a firm's average volatility. To measure if VEDs attract TII, the study regresses the quarterly change in the percentage of TII ownership against the number of VEDs a company releases. For the period 2007 through 2012, the study uses the S&P 500 companies' quarterly 8-K reports, TII percentage ownership changes, and daily market prices (used to calculate the DMI) as the test data. The study finds that market price volatility does exist during the VED event periods. The market price volatility indicates managers are using VEDs to manage earnings and as a consequence to degrade investor pricing decisions. The length of the volatility events supports managers' ability to create non-equilibrium pricing moments that benefit insider trades. However, TII do not see VEDs as an attractant for investment in a firm and TII avoid investing in companies issuing above average numbers of VEDs." -- Page [iv].

Download or read book Investment Intelligence from Insider Trading written by H. Nejat Seyhun and published by MIT Press. This book was released on 2000-02-28 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learn how to profit from information about insider trading. The term insider trading refers to the stock transactions of the officers, directors, and large shareholders of a firm. Many investors believe that corporate insiders, informed about their firms' prospects, buy and sell their own firm's stock at favorable times, reaping significant profits. Given the extra costs and risks of an active trading strategy, the key question for stock market investors is whether the publicly available insider-trading information can help them to outperform a simple passive index fund. Basing his insights on an exhaustive data set that captures information on all reported insider trading in all publicly held firms over the past twenty-one years—over one million transactions!—H. Nejat Seyhun shows how investors can use insider information to their advantage. He documents the magnitude and duration of the stock price movements following insider trading, determinants of insiders' profits, and the risks associated with imitating insider trading. He looks at the likely performance of individual firms and of the overall stock market, and compares the value of what one can learn from insider trading with commonly used measures of value such as price-earnings ratio, book-to-market ratio, and dividend yield.
Download or read book Insider Trading Stock Return Volatility and the Option Market s Pricing of the Information Content of Insider Trading written by Chin-Han Chiang and published by . This book was released on 2016 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: We find strong evidence that net insider selling is positively associated with future stock return volatility, consistent with insider selling increasing outside investors' uncertainty. The positive effect of net insider selling is significantly stronger when the volatility is measured around the earnings announcement. Apparently, option prices do not fully reflect the information content of insider trading for future volatility. More specifically, we find no evidence that option traders adjust the implied volatility for the insider trading effect in a timely manner. Consequently, net insider selling is significantly associated with future option straddle returns and delta neutral returns.

Download or read book Aggregate Insider Trading and Stock Market Volatility in the UK written by Guglielmo Maria Caporale and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the relationship between aggregate insider trading (AIT) and stock market volatility using monthly data on insider transactions by UK executives in public limited companies for the period January 2002 - December 2020. More specifically, a Vector Autoregression (VAR) model is estimated and Impulse Response analysis as well as Forecast Error Variance Decomposition are carried out. The main finding is that higher AIT (more specifically, insider purchases) leads to a short-run increase in stock market volatility; this can be attributed to a combination of insiders manipulating the timing and content of the information they release and the revelation of new economy-wide information to the market. The UK being a well-regulated market, it is plausible that the main driver of the increase in stock market volatility should be the information effect. These results are shown to be robust to using alternative (direct) measures of AIT.

Download or read book Insider Trading and the Bid Ask Spread written by Stanislav Dolgopolov and published by . This book was released on 2006 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: In economic, finance, and legal literature, there is a widespread acceptance of the notion that market makers increase the bid-ask spread in response to insider trading, as they consistently lose money by transacting with better-informed insiders. The development of this adverse selection model of market making was treated as proof that insider trading imposes a real cost on securities markets by decreasing liquidity and increasing the corporate cost of capital and was used as a justification for regulation. This Article is a critical review of the adverse selection literature. It discusses the model's theoretical development, its use in the regulation debates, a summary of the case law on the harm from insider trading to market makers, and empirical research on the link between insider trading and transaction costs. The adverse selection argument is criticized from both theoretical and empirical standpoints: there are limitations to the model due to required assumptions about the role and behavior of market makers' inventories; different causal links among insider trading, firm size, quality of disclosure, stock price volatility, and the bid-ask spread are possible; the existing empirical studies may confuse various components of the spread; and information asymmetry may actually benefit market makers.
Download or read book Insider Trading Stochastic Liquidity and Equilibrium Prices written by Pierre Collin-Dufresne and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We extend Kyle's (1985) model of insider trading to the case where liquidity provided by noise traders follows a general stochastic process. Even though the level of noise trading volatility is observable, in equilibrium, measured price impact is stochastic. If noise trading volatility is mean-reverting, then the equilibrium price follows a multivariate 'stochastic bridge' process, which displays stochastic volatility. This is because insiders choose to optimally wait to trade more aggressively when noise trading activity is higher. In equilibrium, market makers anticipate this, and adjust prices accordingly. More private information is revealed when volatility is higher. In time series, insiders trade more aggressively, when measured price impact is lower. Therefore, execution costs to uninformed traders can be higher when price impact is lower.
Download or read book Market Liquidity written by Thierry Foucault and published by Oxford University Press. This book was released on 2023 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The process by which securities are traded is very different from the idealized picture of a frictionless and self-equilibrating market offered by the typical finance textbook. This book offers a more accurate and authoritative take on this process. The book starts from the assumption that not everyone is present at all times simultaneously on the market, and that participants have quite diverse information about the security's fundamentals. As a result, the order flow is a complex mix of information and noise, and a consensus price only emerges gradually over time as the trading process evolves and the participants interpret the actions of other traders. Thus, a security's actual transaction price may deviate from its fundamental value, as it would be assessed by a fully informed set of investors. The book takes these deviations seriously, and explains why and how they emerge in the trading process and are eventually eliminated. The authors draw on a vast body of theoretical insights and empirical findings on security price formation that have come to form a well-defined field within financial economics known as "market microstructure." Focusing on liquidity and price discovery, the book analyzes the tension between the two, pointing out that when price-relevant information reaches the market through trading pressure rather than through a public announcement, liquidity may suffer. It also confronts many striking phenomena in securities markets and uses the analytical tools and empirical methods of market microstructure to understand them. These include issues such as why liquidity changes over time and differs across securities, why large trades move prices up or down, and why these price changes are subsequently reversed, and why we observe temporary deviations from asset fair values"--
Download or read book The New Stock Market written by Merritt B. Fox and published by Columbia University Press. This book was released on 2019-01-08 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
