85-900: In the 1950s, Harry Markowitz , an American economist, developed the modern portfolio theory . Jack Treynor (1961, 1962), William F. Sharpe (1964), John Lintner (1965) and Jan Mossin (1966) later build the Capital Asset Pricing Model (CAPM) on the theory of Markowitz. Nowadays, the CAPM is one of the primary portfolio management tools. The formula calculates the potential return percentage of an investment vehicle based on its vested risk appetite. The formula is: μ i = r f + ( μ M − r f ) ∗ β i {\displaystyle \mu _{i}=r_{f}+(\mu _{M}-r_{f})*\beta _{i}} where: The goal of an investment manager

170-630: A commodity broker can be charged with fraud for receiving a large purchase order from a client (one likely to affect the price of that commodity) and then purchasing that commodity before executing the client's order to benefit from the anticipated price increase. Some economists and legal scholars (such as Henry Manne , Milton Friedman , Thomas Sowell , Daniel Fischel , and Frank H. Easterbrook ) have argued that laws against insider trading should be repealed. They claim that insider trading based on material nonpublic information benefits investors, in general, by more quickly introducing new information into

255-620: A PM facilitates the delivery of updated prices and market information to allow for trade orders, trade executions, and their overall portfolio value. The IT infrastructure, known as a portfolio management system (PMS), include components such as an order management system , execution management system , portfolio valuation, risk, and compliance. A front-back PMS will also include a middle office and back office components such as trade management, pre/post-trade tools, cash management, and net asset value calculations. Harry Markowitz Harry Max Markowitz (August 24, 1927 – June 22, 2023)

340-415: A company's officers, directors and any beneficial owners of more than 10% of a class of the company's equity securities. Trades made by these types of insiders in the company's own stock, based on material non-public information, are considered fraudulent since the insiders are violating the fiduciary duty that they owe to the shareholders. The corporate insider, simply by accepting employment, has undertaken

425-470: 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 trades on the basis of this information. Liability for inside trading violations generally cannot be avoided by passing on the information in an "I scratch your back; you scratch mine" or quid pro quo arrangement if

510-502: A crime. Trading by specific insiders, such as employees, is commonly permitted as long as it does not rely on material information not available to the general public. Many jurisdictions require that such trading be reported so that the transactions can be monitored. In the United States and several other jurisdictions, trading conducted by corporate officers, key employees, directors, or significant shareholders must be reported to

595-403: A fund or asset management vehicle. In the case of mutual and exchange-traded funds (ETFs), there are two forms of portfolio management: passive and active. Passive management simply tracks a market index, commonly referred to as indexing or index investing. Active management involves a single manager, co-managers, or a team of managers who attempt to beat the market return by actively managing

680-544: A fund's portfolio through investment decisions based on research and decisions on individual holdings. Closed-end funds are generally actively managed. A portfolio manager risks losing his past compensation if he engages in insider trading ; in fact, lawyers at the law firm Davis & Gilbert wrote in an article in a 2014 article in Financial Fraud Law Report that: "Based upon courts current application of New York's faithless servant doctrine, it

765-685: A higher value for the market than trading on positive information. The US and the UK vary in the way the law is interpreted and applied with regard to insider trading. In the UK, the relevant laws are the Criminal Justice Act 1993 , Part V, Schedule 1; the Financial Services and Markets Act 2000 , which defines an offence of " market abuse "; and the European Union Regulation No 596/2014. The principle

850-556: A legal obligation to the shareholders to put the shareholders' interests before their own, in matters related to the corporation. When insiders buy or sell based on company-owned information, they are said to be violating their obligation to the shareholders or investors. For example, illegal insider trading would occur if the chief executive officer of Company A learned (prior to a public announcement) that Company A would be taken over and then bought shares in Company A while knowing that

935-443: A loss is owed an actual legal duty by the insiders in question. Opponents of political insider trading point to conflict of interests and social distrust . Rules prohibiting or criminalizing insider trading on material non-public information exist in most jurisdictions around the world (Bhattacharya and Daouk, 2002), but the details and the efforts to enforce them vary considerably. In the United States, Sections 16(b) and 10(b) of

1020-526: A number of notorious cases where individuals were able to escape prosecution. Instead the UK regulators relied on a series of fines to punish market abuses. These fines were widely perceived as an ineffective deterrent, and there was a statement of intent by the UK regulator (the Financial Services Authority) to use its powers to enforce the legislation (specifically the Financial Services and Markets Act 2000 ). Between 2009 and 2012

1105-522: A place for soliciting for corporate informants, where non-public information may be used for purposes other than stock trading. A study of political insider trading found existing regulation including STOCK Act results in conflict of interest and contributes to social distrust . Information asymmetry enjoyed by politicians was found to be high, which does not confirm the predictions of social contract theory. Political insider trading by persons which are not required to report according to STOCK Act

1190-580: A private hedge fund, AMC was sold to Stuart & Co. in 1971. A year later, Markowitz left the company. Years later, he was involved with CACI's SIMSCRIPT addition of Object-oriented features. Markowitz divided his time between teaching (he was an adjunct professor at the Rady School of Management at the University of California at San Diego, UCSD); video casting lectures; and consulting (out of his Harry Markowitz Company offices). He served on

1275-543: A third party, with securities: Penalty - imprisonment, from 1 (one) to 5 (five) years, and a fine of up to 3 (three) times the amount of the illicit advantage obtained as a result of the crime." The first conviction handed down in Brazil for the practice of the offense of "misuse of privileged information" occurred in 2011, by federal judge Marcelo Costenaro Cavali, of the Sixth Criminal Court of São Paulo. It

1360-431: A victimless crime". Legalization advocates also question why "trading" where one party has more information than the other 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

1445-539: A widespread belief that insider trading takes place on a regular basis in India, there were few examples of insider traders being prosecuted in India. One former top regulator said that in India insider trading is deeply rooted and especially rampant because regulators do not have the tools to address it. In the few cases where prosecution has taken place, cases have sometimes taken more than a decade to reach trial, and punishments have been light; and despite SEBI by law having

1530-409: Is about strengths, weaknesses, opportunities, and threats in the choice of debt vs. equity , domestic vs. international, growth vs. safety, and other trade-offs encountered in the attempt to maximize return at a given appetite for risk. Portfolio managers are presented with investment ideas by internal buy-side analysts and sell-side analysts from investment banks . It is their job to sift through

1615-610: Is also prohibited to prevent the director of a company (the insider) from abusing a company's confidential information for the director's personal gain. The rules governing insider trading are complex and vary significantly from country to country. The extent of enforcement also varies from one country to another. The definition of insider in one jurisdiction can be broad and may cover not only insiders themselves but also any persons related to them, such as brokers, associates, and even family members. A person who becomes aware of non-public information and trades on that basis may be guilty of

1700-550: Is an illegal act under Brazilian law, since it constitutes unfair behavior that threatens the security and equality of legal conditions in the market. Since 2001, the practice is also considered a crime. Law 6,385/1976, as amended by Law 10,303/2001, provided for Article 27-D, which typifies the conduct of "Using relevant information not yet disclosed to the market, of which he is aware and from which he must maintain secrecy, capable of providing, for himself or for others, undue advantage, through trading, on his own behalf or on behalf of

1785-575: Is an offense according to Sections 12A and 15G of the Securities and Exchange Board of India Act, 1992 , and the Securities and Exchange Board of India (Prohibition of Insider Trading) Regulations, 2015. Insider trading is when one with access to non-public, price-sensitive information about the securities of the company subscribes, buys, sells, or deals, or agrees to do so or counsels another to do so as principal or agent. Price-sensitive information

1870-466: Is held to a higher standard. If this type of information is obtained (directly or indirectly) and there is reason to believe it is nonpublic, there is a duty to disclose it or abstain from trading. In the United States in addition to civil penalties, the trader may also be subject to criminal prosecution for fraud or where SEC regulations have been broken, the U.S. Department of Justice (DOJ) may be called to conduct an independent parallel investigation. If

1955-468: Is illegal, most insider trading is never detected by law enforcement, and thus the illegality of insider trading might give the public the potentially misleading impression that "stock market trading is an unrigged game that anyone can play." Some legal analysis has questioned whether insider trading actually harms anyone in the legal sense, since some have questioned whether insider trading causes anyone to suffer an actual "loss" and whether anyone who suffers

2040-716: Is illegal. Indeed, previously it was regarded as common sense to make a profit from your knowledge." In Malta the law follows the European broader scope model. The relevant statute is the Prevention of Financial Markets Abuse Act of 2005, as amended. Earlier acts included the Financial Markets Abuse Act in 2002, and the Insider Dealing and Market Abuse Act of 1994. The International Organization of Securities Commissions (IOSCO) paper on

2125-430: Is information for the market. Other argue that insider trading is a victimless act: a willing buyer and a willing seller agree to trade property that 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 . The Atlantic has described the process as "arguably the closest thing that modern finance has to

2210-414: Is information that materially affects the value of the securities. The penalty for insider trading is imprisonment, which may extend to five years, and a minimum of five lakh rupees (500,000) to 25 crore rupees (250 million) or three times the profit made, whichever is higher. The Wall Street Journal , in a 2014 article entitled "Why It's Hard to Catch India's Insider Trading", said that despite

2295-471: Is less effectively restrained. The current Australian legislation arose out of the report of a 1989 parliamentary committee report which recommended removal of the requirement that the trader be 'connected' with the body corporate. This may have weakened the importance of the fiduciary duty rationale and possibly brought new potential offenders within its ambit. In Australia if a person possesses inside information and knows, or ought reasonably to know, that

2380-415: Is now accepted in U.S. law. It states that anyone who misappropriates material non-public information and trades on that information in any stock may be guilty of insider trading. This can include elucidating material non-public information from an insider with the intention of trading on it or passing it on to someone who will. This theory constitutes the background for the securities regulation that enforces

2465-406: Is one where diversification cannot lower the portfolio's risk for a given return expectation (alternately, no additional expected return can be gained without increasing the risk of the portfolio). The Markowitz Efficient Frontier is the set of all portfolios that will give the highest expected return for each given level of risk. These concepts of efficiency were essential to the development of

2550-582: Is that it is illegal to trade on the basis of market-sensitive information that is not generally known. This is a much broader scope than under U.S. law. The key differences from U.S. law are that no relationship to either the issuer of the security or the tipster is required; all that is required is that the guilty party traded (or caused trading) whilst having inside information, and there is no scienter requirement under UK law. Japan enacted its first law against insider trading in 1988. Roderick Seeman said, "Even today many Japanese do not understand why this

2635-487: Is the case of the Sadia - Perdigão merger. The former Director of Finance and Investor Relations, Luiz Gonzaga Murat Júnior, was sentenced to one year and nine months in prison in an open regime, replaceable by community service, and the inability to exercise the position of administrator or fiscal councilor of a publicly traded company for the time he serves his sentence, in addition to a fine of R$ 349,711.53.

This return can be monitored by investors through weekly, monthly, quarterly, or yearly performance reports that are shared by the PM. The manager may set up a performance benchmark or track their investment strategy alongside an index. The investment policy shared by the manager outlines investment details, such as minimum investment requirements, liquidity provisions, investment strategy, and

2805-505: Is virtually certain that if ... hedge fund ... managers engage in wrongdoing ... those .. managers will be forced to disgorge all compensation received during the period the wrongdoing occurred". In Morgan Stanley v. Skowron , 989 F. Supp. 2d 356 (S.D.N.Y. 2013), applying New York's faithless servant doctrine, the court held that a hedge fund's PM engaging in insider trading in violation of his company's code of conduct, which also required him to report his misconduct, must repay his employer

The company that would become CACI International was founded by Herb Karr and Harry Markowitz on July 17, 1962, as California Analysis Center, Inc. They helped develop SIMSCRIPT , the first simulation programming language, at RAND and after it

2975-569: The U.S. Sentencing Guidelines . This means that first-time offenders are eligible to receive probation rather than incarceration. U.S. insider trading prohibitions are based on English and American common law prohibitions against fraud. In 1909, well before the Securities Exchange Act was passed, the United States Supreme Court ruled that a corporate director who bought that company's stock when he knew

3060-643: The capital asset pricing model . Markowitz also co-edited the textbook The Theory and Practice of Investment Management with Frank J. Fabozzi of Yale School of Management . In the same line, Markowitz was part of the Editorial Board of AESTIMATIO, the IEB International Journal of Finance.

It was also in 1952 that Markowitz published Portfolio Selection , his first paper dissecting investment portfolio strategy. In 1954, he received a PhD in economics from the University of Chicago with a thesis on the portfolio theory. The topic

3230-480: The stock market as the topic for his dissertation. Jacob Marschak, who was the thesis advisor, encouraged him to pursue the topic, noting that it had also been a favorite interest of Alfred Cowles , the founder of the Cowles Commission. While researching the then current understanding of stock prices, which at the time consisted in the present value model of John Burr Williams , Markowitz realized that

3315-519: The "Objectives and Principles of Securities Regulation" (updated to 2003) states that the three objectives of good securities market regulation are investor protection, ensuring that markets are fair, efficient and transparent, and 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

In 2016 a number of dark web sites were identified as marketplaces where such non-public information was bought and sold. At least one such site used bitcoins to avoid currency restrictions and to impede tracking. Such sites also provide

Until the 21st century and the European Union's market abuse laws, the United States was the leading country in prohibiting insider trading made on the basis of material non-public information. Thomas Newkirk and Melissa Robertson of the SEC summarize the development of US insider trading laws. Insider trading has a base offense level of 8, which puts it in Zone ;A under

3740-418: The Securities Exchange Act of 1934 directly and indirectly address insider trading. The U.S. Congress enacted this law after the stock market crash of 1929. While the United States is generally viewed as making the most serious efforts to enforce its insider trading laws, the broader scope of the European model legislation provides a stricter framework against illegal insider trading. In the European Union and

3825-558: The U.S. Attorney's Office for further investigation and prosecution. In the United States and most non-European jurisdictions, not all trading on non-public information is illegal insider trading. For example, a person in a restaurant who hears the CEO of Company A at the next table tell the CFO that the company's profits will be higher than expected and then buys the stock is not guilty of insider trading—unless he or she had some closer connection to

3910-522: The United Kingdom, all trading on non-public information is, under the rubric of market abuse , subject at a minimum to civil penalties and possible criminal penalties as well. UK's Financial Conduct Authority has the responsibility to investigate and prosecute insider dealing, defined by the Criminal Justice Act 1993 . In the United States, Canada, Australia, Germany and Romania for mandatory reporting purposes, corporate insiders are defined as

3995-411: The United States because there is no possibility of imprisonment. Punishment may include monetary fees or temporary relieving from a position in the company. The Chinese do not view insider trading as a crime worth prison time because generally the person has a clean record and a path of success with references to deter them from being viewed as a criminal. On October 1, 2015, Chinese fund manager Xu Xiang

The U.S. SEC alleged that in 2009 Kuwaiti trader Hazem Al-Braikan engaged in insider trading after misleading the public about possible takeover bids for two companies. Three days after Al-Braikan was sued by the SEC, he was found dead of a gunshot wound to

He was also fined R$ 374,940.52. In 2008, police uncovered an insider trading conspiracy involving Bay Street and Wall Street lawyer Gil Cornblum who had worked at Sullivan & Cromwell and

4335-401: The cases can be settled or litigated. Payment of disgorgement can be either completely or partially waived based on the defendant demonstrating an inability to pay. In settled administrative proceedings, Enforcement may recommend, if appropriate, that the disgorgement be waived. There are several approaches in order to quantify the disgorgement; an innovative procedure based on probability theory

There was a deadline for companies to convert their shares and the deadline was short, due to this there was a massive amount of exchanges and in the midst of these exchanges many people committed insider trading knowing that the selling of these shares would affect prices. Chinese people did not fear insider trading as much as one may in

4505-405: The company or company officers. However, even where the tippee is not himself an insider, where the tippee knows that the information is non-public and the information is paid for, or the tipper receives a benefit for giving it, then in the broader-scope jurisdictions the subsequent trading is illegal. Notwithstanding, information about a tender offer (usually regarding a merger or acquisition)

4590-446: The company. In various countries, some kinds of trading based on insider information is illegal. The rationale for this prohibition of insider trading differs between countries/regions. Some view it as unfair to other investors in the market who do not have access to the information, as the investor with inside information could potentially make larger profits than an investor (without such information) could make. However, insider trading

Punishment for communicating about a development pertinent to the next day's stock price might seem an act of censorship. Some authors have used these arguments to propose legalizing insider trading on negative information (but not on positive information). Since negative information is often withheld from the market, trading on such information has

The SEC later reached a $ 6.5 million settlement of civil insider trading charges, with his estate and others. In 2009, a journalist in Nettavisen (Thomas Gulbrandsen) was sentenced to four months in prison for insider trading. The longest prison sentence in a Norwegian trial where the main charge

4930-440: The information is not generally available and is materially price sensitive then the insider must not trade. Nor must she or he procure another to trade and must not tip another. Information will be considered generally available if it consists of readily observable matter or it has been made known to common investors and a reasonable period for it to be disseminated among such investors has elapsed. The practice of insider trading

5015-425: The insider can demonstrate that the trades conducted on behalf of the insider were conducted as part of a pre-existing contract or written binding plan for trading in the future. For example, if an insider expects to retire after a specific period of time and, as part of retirement planning, the insider has adopted a written binding plan to sell a specific amount of the company's stock every month for two years, and

5100-529: The insider later comes into possession of material nonpublic information about the company, trades based on the original plan might not constitute prohibited insider trading. 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 (corn, wheat, steel, etc.). However, analogous activities such as front running are illegal under US commodity and futures trading laws. For example,

5185-447: The insider released the information for an improper purpose. One commentator has argued that if Company A's CEO did not trade on 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 (albeit by proxy, by passing it on to a "non-insider" so Company A's CEO would not get his hands dirty).

5270-502: The insider trading. Disgorgement represents ill-gotten gains (or losses avoided) resulting from individuals violating the securities laws. In general in the countries where the insider trading is forbidden, the competent Authority seeks disgorgement to ensure that securities law violators do not profit from their illegal activity. When appropriate, the disgorged funds are returned to the injured investors. Disgorgements can be ordered in either administrative proceedings or civil actions, and

5355-479: 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. Larry Harris claims that differences in the effectiveness with which countries restrict insider trading help to explain the differences in executive compensation among those countries. The US, for example, has much higher CEO salaries than have Japan or Germany, where insider trading

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

While still a student, he was invited to become a member of the Cowles Commission for Research in Economics , which was in Chicago at the time. He completed his A.M. in Economics from the university in 1950. Markowitz chose to apply mathematics to the analysis of

5780-401: The person receiving the information knew or should have known that the information was material non-public information. In the United States, at least one court has indicated that the insider who releases the non-public information must have done so for an improper purpose. In the case of a person who receives the insider information (called the "tippee"), the tippee must also have been aware that

5865-439: The prohibition against insider trading does not require proof that an insider actually used material nonpublic information when conducting a trade; possession of such information alone is sufficient to violate the provision, and the SEC would infer that an insider in possession of material nonpublic information used this information when conducting a trade. However, SEC Rule 10b5-1 also created for insiders an affirmative defense if

5950-809: The regulator or publicly disclosed, usually within a few business days of the trade. In these cases, insiders in the United States are required to file Form 4 with the U.S. Securities and Exchange Commission (SEC) when buying or selling shares of their own companies. The authors of one study claim that illegal insider trading raises the cost of capital for securities issuers, thus decreasing overall economic growth. Some economists, such as Henry Manne , argued that insider trading should be allowed and could, in fact, benefit markets. There has long been "considerable academic debate" among business and legal scholars over whether or not insider trading should be illegal. Several arguments against outlawing insider trading have been identified: for example, although insider trading

6120-409: The share price would likely rise. In the United States and many other jurisdictions, "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 where

6205-522: The theory lacks an analysis of the impact of risk. This insight led to the development of his seminal theory of portfolio allocation under uncertainty, published in 1952 by the Journal of Finance . In 1952, Harry Markowitz went to work for the RAND Corporation , where he met George Dantzig . With Dantzig's help, Markowitz continued to research optimization techniques, further developing

6290-414: The theory of three fields: portfolio theory; sparse matrix methods; and simulation language programming ( SIMSCRIPT ). Sparse matrix methods are now widely used to solve very large systems of simultaneous equations whose coefficients are mostly zero. SIMSCRIPT has been widely used to program computer simulations of manufacturing, transportation, and computer systems as well as war games. SIMSCRIPT (I) included

He is best known for his pioneering work in modern portfolio theory , studying the effects of asset risk , return , correlation and diversification on probable investment portfolio returns. Harry Markowitz
