Results indicate that much information Jaffe (1974) contained in the trades remains undiscounted by the publication date in the official summary (p. 427). Insider data contains information on future stock prices, a finding inconsistent with much of the research on efficient capital markets (p. 428).

Insiders obtain trading gains from the use of inside information. The answer to this Givoly & question has clear implications for market efficiency: under the semi-strong form of Palmon the efficient market hypothesis, all public information is fully reflected in prices (p. (1985) 69). Insiders outperform the market, thus refuting the strong form of the efficient mar- ket hypothesis (p. 70). Insiders predict abnormal future stock price changes. Seyhun Insiders possess differences in the quality of information. Insiders who are expected (1986) to be more knowledgeable with the overall affairs of the firm, such as CEO, board of directors, or officers, are more successful predictors of future abnormal stock price changes (p. 210). The realizable return to outsiders is examined. Following the public dissemination of insider-trading information, the abnormal return to outsiders, net of the bid-ask spread plus the commission fee is non-positive (p. 211). Concerning strong-form market efficiency, the evidence examined indicated a level Rozeff & of insider trading profits of, at most 5% annually, rejecting the strong-form efficien- Zaman cy in a statistical sense (p. 39).

Sidgman Electronic filing of changes in ownership began by insiders on June 30, 2003 (p. 3 (2014) footnote 4). The concept of efficiency is central to finance. For many years, academics and Titian (2015) economists have studied the concept of efficiency applied to capital markets, with efficient market hypothesis (EMH) being a major research area in the specialized literature (p. 442). Financial market anomalies are found to be inconsistent with the predictions of Mahakud & traditional efficient markets and rational expectations asset pricing theory (p. 236).

Muma Business Review 59 Legal Insider Trading Table 2: Insider Trading Ethics Findings Finding Sources Opponents of insider trading seem simply to believe that insider trading is Ma & Sun (1998) inherently immoral (p. 67). Proponents, on the other hand, assert that insider trading is a viable and effi- cient economic means and can be used to serve the best interests of sharehold- ers and the economy at large (p. 67). They argue that insider trading is not necessarily unethical or illegal (p. 68). Whenever the term insider trading is used, the average listener/reader imme- McGee (2008) diately classifies it as a bad practice or something that is immoral or unethical (p. 207). The strongest criticism that has been leveled against the U.S.’s insider trading legislation is that the term insider trading was not defined. That omission was deliberate, perhaps because Congress could not clearly define what insider trading was (p. 214). Commentators make it sound like all insider trading is illegal. Yet, some McGee (2009) forms of insider trading are perfectly legal and some kinds of insider trading are not unethical. In other words, there is a widespread misperception on the part of the public about insider trading (p. 65). Arguments against all insider trading say it is inherently immoral to trade on inside information because making a large profit with such little effort is somehow wrong (p. 71). Another argument against all insider trading takes the position that insiders have some fiduciary duty not to benefit from the information they have access to as part of their position with the corporation (p. 71). Trading on undisclosed price-relevant information is in breach of moral Keenan (2000) rights and duties derived from the principle of respect for individual autono- my. It follows that insider trading is an immoral practice (p. 81). Reliable financial reporting is an important mechanism used by firms to Skaife, Veenman, communicate creditable information to outsiders for their use in evaluating & Wangerin (2013) management’s performance (p. 91). Insider trading profitability is significantly higher in firms disclosing material weaknesses in internal control over financial reporting (p. 92). They argue that unless the existing compliance-based system of regulatory Batten, Loncarski, rules and industry standards come to reflect core ethical values, then insider & Szilagyi (2018) trading and other illegal and unfair market practices will remain common- place (p. 780).
