Insider trading is the trading of a corporation's stock or other securities (e.g. bonds or stock options) by individuals with potential access to non-public information about the company. In most countries, trading by corporate insiders such as officers, key employees, directors, and large shareholders may be legal, if this trading is done in a way that does not take advantage of non-public information. However, the term is frequently used to refer to a practice in which an insider or a related party trades based on material non-public information obtained during the performance of the insider's duties at the corporation, or otherwise in breach of a fiduciary duty or other relationship of trust and confidence or where the non-public information was misappropriated from the company.
In the United States and several other jurisdictions, trading conducted by corporate officers, key employees, directors, or significant shareholders (in the U.S., defined as beneficial owners of ten percent or more of the firm's equity securities) must be reported to the regulator or publicly disclosed, usually within a few business days of the trade. Many investors follow the summaries of these insider trades in the hope that mimicking these trades will be profitable. While "legal" insider trading cannot be based on material non-public information, some investors believe corporate insiders nonetheless may have better insights into the health of a corporation (broadly speaking) and that their trades otherwise convey important information (e.g., about the pending retirement of an important officer selling shares, greater commitment to the corporation by officers purchasing shares, etc.)
Illegal insider trading is believed to raise the cost of capital for securities issuers, thus decreasing overall economic growth.
For example, illegal insider trading would occur if the chief executive officer of Company A learned (prior to a public announcement) that Company A will be taken over, and bought shares in Company A knowing that the share price would likely rise.
In the United States and many other jurisdictions, however, "insiders" are not just limited to corporate officials and major shareholders where illegal insider trading is concerned, but can include any individual who trades shares based on material non-public information in violation of some duty of trust. This duty may be imputed; for example, in many jurisdictions, in cases of where the a corporate insider "tips" a friend about non-public information likely to have an effect on the company's share price, the duty the corporate insider owes the company is now imputed to the friend and the friend violates a duty to the company if he or she trades on the basis of this information.
For example, if Company A's CEO did not trade on the undisclosed takeover news, but instead passed the information on to his brother-in-law who traded on it, illegal insider trading would still have occurred.
For example, if a journalist who worked for Company B learned about the takeover of Company A while performing his work duties, and bought stock in Company A, illegal insider trading might still have occurred. Even though the journalist did not violate a fiduciary duty to Company A's shareholders, he might have violated a fiduciary duty to Company B's shareholders (assuming the newspaper had a policy of not allowing reporters to trade on stories they were covering).
As of December 2005 companies are required to announce times to their employees as to when they can safely trade without being accused of trading on inside information.
Section 16(b) of the Securities Exchange Act of 1934 prohibits short-swing profits (from any purchases and sales within any six month period) made by corporate directors, officers, or stockholders owning more than 10% of a firm’s shares. Under Section 10(b) of the 1934 Act, SEC Rule 10b-5, prohibits fraud related to securities trading.
The Insider Trading Sanctions Act of 1984 and the Insider Trading and Securities Fraud Enforcement Act of 1988 provide for penalties for illegal insider trading to be as high as three times the profit gained or the loss avoided from the illegal trading.
In SEC v. Texas Gulf Sulphur Co. (1966), a federal circuit court stated that anyone in possession of inside information must either disclose the information or refrain from trading.
In 1984, the Supreme Court of the United States ruled in the case of Dirks v. SEC that tippees (receivers of second-hand information) are liable if they had reason to believe that the tipper had breached a fiduciary duty in disclosing confidential information and the tipper received any personal benefit from the disclosure. (Since Dirks disclosed the information in order to expose a fraud, rather than for personal gain, nobody was liable for insider trading violations in his case.)
The Dirks case also defined the concept of "constructive insiders," who are lawyers, investment bankers and others who receive confidential information from a corporation while providing services to the corporation. Constructive insiders are also liable for insider trading violations if the corporation expects the information to remain confidential, since they acquire the fiduciary duties of the true insider.
In United States v. Carpenter (1986) the U.S. Supreme Court cited an earlier ruling while unanimously upholding mail and wire fraud convictions for a defendant who received his information from a journalist rather than from the company itself. The journalist R. Foster Winans was also convicted, on the grounds that he had misappropriated information belonging to his employer, the Wall Street Journal. In that widely publicized case, Winans traded in advance of "Heard on the Street" columns appearing in the Journal.
The court ruled in Carpenter: "It is well established, as a general proposition, that a person who acquires special knowledge or information by virtue of a confidential or fiduciary relationship with another is not free to exploit that knowledge or information for his own personal benefit but must account to his principle for any profits derived therefrom."
However, in upholding the securities fraud (insider trading) convictions, the justices were evenly split.
In 1997 the U.S. Supreme Court adopted the misappropriation theory of insider trading in United States v. O'Hagan, 521 U.S. 642, 655 (1997). O'Hagan was a partner in a law firm representing Grand Metropolitan, while it was considering a tender offer for Pillsbury Co. O'Hagan used this inside information by buying call options on Pillsbury stock, resulting in profits of over $4 million. O'Hagan claimed that neither he nor his firm owed a fiduciary duty to Pillsbury, so that he did not commit fraud by purchasing Pillsbury options.
The Court rejected O'Hagan's arguments and upheld his conviction.
The "misappropriation theory" holds that a person commits fraud "in connection with" a securities transaction, and thereby violates 10(b) and Rule 10b-5, when he misappropriates confidential information for securities trading purposes, in breach of a duty owed to the source of the information. Under this theory, a fiduciary's undisclosed, self-serving use of a principal's information to purchase or sell securities, in breach of a duty of loyalty and confidentiality, defrauds the principal of the exclusive use of the information. In lieu of premising liability on a fiduciary relationship between company insider and purchaser or seller of the company's stock, the misappropriation theory premises liability on a fiduciary-turned-trader's deception of those who entrusted him with access to confidential information.
The Court specifically recognized that a corporation’s information is its property: "A company's confidential information...qualifies as property to which the company has a right of exclusive use. The undisclosed misappropriation of such information in violation of a fiduciary duty...constitutes fraud akin to embezzlement – the fraudulent appropriation to one's own use of the money or goods entrusted to one's care by another."
In 2000, the SEC enacted Rule 10b5-1, which defined trading "on the basis of" inside information as any time a person trades while aware of material nonpublic information so that it is no defense for one to say that she would have made the trade anyway. This rule also created an affirmative defense for pre-planned trades.
In May 2007, a bill entitled the "Stop Trading on Congressional Knowledge Act, or STOCK Act" was introduced that would hold congressional and federal employees liable for stock trades they made using information they gained through their jobs and also regulate analysts or "Political Intelligence" firms that research government activities. The bill has not passed.
Milton Friedman, laureate of the Nobel Memorial Prize in Economics, said: "You want more insider trading, not less. You want to give the people most likely to have knowledge about deficiencies of the company an incentive to make the public aware of that." Friedman did not believe that the trader should be required to make his trade known to the public, because the buying or selling pressure itself is information for the market.
Other critics argue that insider trading is a victimless act: A willing buyer and a willing seller agree to trade property which the seller rightfully owns, with no prior contract (according to this view) having been made between the parties to refrain from trading if there is asymmetric information.
Legalization advocates also question why activity that is similar to insider trading is legal in other markets, such as real estate, but not in the stock market. For example, if a geologist knows there is a high likelihood of the discovery of petroleum under Farmer Smith's land, he may be entitled to make Smith an offer for the land, and buy it, without first telling Farmer Smith of the geological data. Nevertheless, circumstances can occur when the geologist would be committing fraud if he did not disclose the information, e.g. when he had been hired by Farmer Smith to assess the geology of the farm.
Advocates of legalization make free speech arguments. Punishment for communicating about a development pertinent to the next day's stock price might seem to be an act of censorship If the information being conveyed is proprietary information and the corporate insider has contracted to not expose it, he has no more right to communicate it than he would to tell others about the company's confidential new product designs, formulas, or bank account passwords,
There are very limited laws against "insider trading" in the commodities markets, if, for no other reason, than that the concept of an "insider" is not immediately analogous to commodities themselves (e.g., corn, wheat, steel, etc.). However, analogous activities such as front running are illegal under U.S. commodity and futures trading laws. For example, a commodity broker can be charged with fraud if he or she receives a large purchase order from a client (one likely to affect the price of that commodity) and then purchases that commodity before executing the client's order in order to benefit from the anticipated price increase.
In the UK, the relevant laws are the Financial Services Act 1986 and the Financial Services and Markets Act 2000, which defines an offence of Market Abuse. It is also illegal to fail to trade based on inside information (whereas without the inside information the trade would have taken place). It is often legal to deal ahead of a takeover bid, where a party deliberately buys shares in a company in the knowledge that it will be launching a takeover bid.
Japan enacted its first law against insider trading in 1988. Roderick Seeman says: "Even today many Japanese do not understand why this is illegal. Indeed, previously it was regarded as common sense to make a profit from your knowledge.
The "Objectives and Principles of Securities Regulation published by the International Organization of Securities Commissions (IOSCO) in 1998 and updated in 2003 states that the three objectives of good securities market regulation are (1) investor protection, (2) ensuring that markets are fair, efficient and transparent, and (3) reducing systemic risk. The discussion of these "Core Principles" state that "investor protection" in this context means "Investors should be protected from misleading, manipulative or fraudulent practices, including insider trading, front running or trading ahead of customers and the misuse of client assets." More than 85 percent of the world's securities and commodities market regulators are members of IOSCO and have signed on to these Core Principles.
The World Bank and International Monetary Fund now use the IOSCO Core Principles in reviewing the financial health of different country's regulatory systems as part of these organization's financial sector assessment program, so laws against insider trading based on non-public information are now expected by the international community. Enforcement of insider trading laws varies widely from country to country, but the vast majority of jurisdictions now outlaw the practice, at least in principle.
