Insider Trading And Corporate Spinoffs, Charlie Charoenwong, Kuan Yong David Ding, Jing Pan

Research Collection Lee Kong Chian School Of Business

This paper studies insider trading to examine undervaluation as a motive behind corporate spinoffs. We show an unmistakable increase (decrease) in the number of insider purchases (sales) and net purchases (sales) in the four quarters prior to a spinoff announcement. In addition, relative to a benchmark period, insider selling is significantly lower, and their net purchases significantly higher, in the three quarters prior to a spinoff announcement compared to other periods. We find that announcement period excess returns for abnormal net insider purchases are significantly higher than excess returns for abnormal net insider sales. Moreover, only firms with abnormal net …

Cost Of Capitol: Analyzing Congressional Insider Trading Regulation, Hannah Levy

Finance Undergraduate Honors Theses

The United States Congress has involved itself with the financial regulation of big business for decades. The legislative body has passed a multitude of laws over time which foster greater transparency and trust between individual investors and big business. Until recently, legislators have avoided passing laws which regulate their own financial activity. Recent investigations revealing that dozens of federal lawmakers have violated financial disclosure laws and made stock trades on insider information has successfully angered the public and forced Congress to consider tighter restrictions. But can Americans trust their legislators to effectively regulate themselves? If no legislative action is taken, …

Insider Sales Under The Threat Of Short Sellers: New Hypothesis And New Tests, Kemin Wang, Rencheng Wang, K. C. John Wei, Bohui Zhang, Yi Zhou

Research Collection School Of Accountancy

Using the Regulation SHO program as a quasi-experiment, we document that the threat of short selling has a negative effect on the volume of opportunistic insider selling and a positive effect on its profitability for each transaction. These effects are stronger among firms with higher litigation risk, greater media coverage, and executives who have more of their firms' stock-related holdings. We further find robust evidence when we extend the analyses to short selling deregulations in the Chinese and Hong Kong stock exchanges. Overall, our findings suggest that short sellers play a disciplinary role in opportunistic insider selling.

Three Essays On Splits, Insiders, And Retail Traders, Paul Van Nes

Theses and Dissertations (Comprehensive)

The first essay tests the split signaling hypothesis by examining the reaction of sophisticated investors to stock split announcements. Return-based tests of signaling used in earlier studies produce conflicting results and have been criticized as unreliable. I bypass this criticism by focusing on long-term post-split behavior of short sellers who are generally recognized as sophisticated investors. Upon controlling for alternative hypotheses and conventional short selling determinants, I show that short interest permanently declines in reaction to split announcements. Furthermore, consistent with signaling, the degree of the decline is positively related to signal strength and to the splitter’s level of information …

Insider Trading As A Precursor To Modern Business Ethics, Robyn Coleman

Finance Undergraduate Honors Theses

There has been a recent change in business that there is more focus on the “stakeholder approach” than shareholder primacy. This can be attributed to the early actions and illegality of insider trading that expected a step beyond a solely economic approach. This attitude was then replicated to become what we see as the modern business approach. Business now includes ethical investing, environmental focus, corporate citizenship, and emphasis on multiple stakeholders that was not always there. Companies have embraced this position while others have been criticized for not doing so. As this approach develops and changes, it will be enlightening …

Analyst Talent, Information, And Investment Strategies, Zhichuan Li, Stephen R. Foerster, Zhenyang Tang, Chongyu Dang

Business Publications

Analyst talent, rather than the number of analysts following a firm, matters most to investors. We find: 1) Analysts with greater “natural” forecasting talent—controlling for experience, brokerage affiliation, and task complexity—contribute relatively more firm-specific rather than industry or market information; 2) Earnings forecasts by low-talent analysts may lead to substantial mispricing; 3) When earnings surprises are large, post-earnings-announcement drift is more prominent among firms covered by low-talent analysts; 4) Firms with low-talent analysts have significantly more insider trading prior to positive earnings news; and 5) Investing following insider trading is more profitable in stocks followed by low-talent analysts.

Newman/Martoma: The Insider Trading Law's Impasse And The Promise Of Congressional Action, Tai H. Park

Fordham Journal of Corporate & Financial Law

The prohibition against insider trading is a judge-made law that has evolved for over fifty years, and has reached a critical impasse in two recent decisions in the Second Circuit Court of Appeals: United States v. Newman and United States v. Martoma. Judges of the Second Circuit are sharply divided over what conduct constitutes improper trading on material nonpublic information (“MNPI”), leaving the law in profound disarray. At bottom, the disagreement stems from a decades-old split within the judiciary about how to (1) ensure a fair securities marketplace, while (2) enabling institutional analysts to probe for corporate information in furtherance …

Chasing Private Information, Marcin Kacperczyk, Emiliano Sebastian Pagnotta

Research Collection Lee Kong Chian School Of Business

Using over 5,000 trades unequivocally based on nonpublic information about firm fundamentals, we find that asymmetric information proxies display abnormal values on days with informed trading. Volatility and volume are abnormally high, whereas illiquidity is low, in equity and option markets. Daily returns reflect the sign of private signals, but bid-ask spreads are lower when informed investors trade. Market makers' learning under event uncertainty and limit orders help explain these findings. The cross-section of information duration indicates that traders select days with high uninformed volume. Evidence from the U.S. SEC Whistleblower Reward Program and the FINRA involvement addresses selection concerns.

Essays In Corporate Finance, Bina Sharma

Theses and Dissertations

In this dissertation, I explore the effects of exogenous shocks on firms' and managers' behaviors. The first essay examines the effect of shareholder-initiated litigation risk on opportunistic insider trading by exploiting US states' staggered adoption of Universal Demand (UD) laws, which weakened shareholders' ability to file derivative lawsuits against corporate insiders. I find that UD laws lead to significantly more profitable insider trades, specifically insider sales. After the adoption of UD laws, insider sales on average avoid an additional loss of about 2 percent ($24,000) per month in buy-and-hold abnormal returns. The benefit of UD laws is greater for insiders …

Competition Of The Informed: Does The Presence Of Short Sellers Affect Insider Selling?, Massimo Massa, Wenlan Qian, Weibiao Xu, Hong Zhang

Research Collection Lee Kong Chian School Of Business

We study how the presence of short sellers affects the incentives of the insiders to trade on negative information. We show it induces insiders to sell more (shares from their existing stakes) and trade faster to preempt the potential competition from short sellers. An experiment and instrumental variable analysis confirm this causal relationship. The effects are stronger for "opportunistic" (i.e., more informed) insider trades and when short sellers' attention is high. Return predictability of insider sales only occurs in stocks with high short-selling potential, suggesting that short sellers indirectly enhance the speed of information dissemination by accelerating trading by insiders. …

Essays On Insider Trading, Xu Sun

Theses and Dissertations - UTB/UTPA

Insider trading has always been an area with high priority for the regulation and enforcement of Securities and Exchange Commission (SEC) programs, as insiders are supposed to possess material, non-public corporate information. The main goal of this dissertation is to examine the insider trading behaviors.

In the first essay, I test whether insiders trade on investor optimism and superior firm performance information in a special context – stock splits. Using insider trading data from Thomson Financial Insider Filing Data Files and stock split announcements from the Center for Research in Security Prices (CRSP), this essay shows that, starting as early …

10b5-1 Plans And Earnings Management By High-Level Executives, Joshua A. Thomas

CMC Senior Theses

Using historical firm financial and insider trading information, this paper examines whether high-level insiders manipulate earnings ahead of their own 10b5-1 equity transactions. The empirical evidence suggests that high-level executives appear to manipulate earnings through real activities such as abnormal discretionary expenditures and abnormal cash flows from operations to influence equity prices ahead of their own transactions under Rule 10b5-1. Evidence also suggests that executives appear to be unlikely to engage in earnings management through highly scrutinized means such as accruals. An interpretation of these results is that high-level executives may be using 10b5-1 plans as an offensive tool to …

Two Essays In Financial Economics, Eric J. Osmer

University of New Orleans Theses and Dissertations

This dissertation consists of two essays: the first investigates informed trading in the Chinese stock exchanges, and the second examines the persistency of correlation of currency future prices.

For the first essay, using a sample of Chinese firms dual-listed in both the China mainland stock exchange and the Hong Kong stock exchange, I investigate the two types of informed trading - insider trading and trading derived from better analysis in the A-and H-share markets. The results suggest that H-shares have relatively more informed trading based on better analysis. In addition, the results from the firm size regression can also be …

Do Option Markets Substitute For Stock Markets?, Tom Arnold, Gayle Erwin, Lance Nail, Terry D. Nixon

Finance Faculty Publications

Using a sample of cash tender offers occurring between 1993 and 2002, we find evidence that the options market has become the preferred venue for traders attempting to profit on anticipated announcements. Options offer advantages relative to stocks. Traders gain leverage by trading in options and multiple options contracts on an individual stock. The results of our study indicate that a substitution effect does exist. Abnormal volume in the option market replaces abnormal volume in the stock market prior to cash tender offer announcements, and this abnormal option volume precedes abnormal stock volume for targets with or without traded options.
