An insider is a person who has access to non-public or confidential information about a corporation. Insiders can include executives, board members, major shareholders, and other employees who have access to sensitive information that is not available to the public. Insider trading refers to the buying or selling of securities, such as stocks or bonds, based on material non-public information.

Insider trading is only illegal when an insider uses confidential information that is not available to the public to make a profit or avoid a loss by trading securities. Insiders are free to trade otherwise. Insider trading has proven to be one of the most underrated and successful stock market anomalies of all time. There is a significant body of academic literature that has identified correlations between insider trading and abnormal investment returns.

A Review of The Profitability of Insider Trading

In 1968, Professors James H. Lorie and Victor Niederhoffer conducted one of the earliest academic researches to determine the profitability of insider trading. Their paper employed a rigorous methodology and demonstrated a strong correlation between insider transactions and abnormal returns. When tracking the returns on insider purchases, they found that when the number of buyers was at least two more than the number of sellers, insiders could generate above-market returns over a six-month period. The same was the case for tracking the returns for insider selling.

In 1974, Wharton professor Jeffrey Jaffe conducted a research to identify a relationship between abnormal returns and insider transactions. He constructed a zero investment portfolio that was long in companies with more insider purchases and short in companies with more insider sales in a given month. Though his study did not find any abnormal returns, even after constraining the sample to only large transactions of at least $20,000, when Jaffe employed an intensive trading criteria he found a strong correlation between insider trading and anomalous returns. When there were at least three buyers and three sellers from each company to be included in the long and short portfolios, respectively, Jaffe found abnormal returns of 5.07% in the first eight months following the transactions. Even when he included each company in the portfolio two months after the transaction, he still found abnormal returns of 4.84% in the first eight months. Hence, Jaffe’s conclusion was that outsiders can also make abnormal profits by mimicking insider activity.

In 1976 Joseph Finnerty, a researcher at the University of Michigan, published a paper that established a correlation between insider trading and its returns. Finnerty did not employ an intensive trading criteria. He found that insider purchases had abnormal returns of 4.1% within the initial six months, and insider sales had abnormal returns of -2.4% within the same time period.

In 1986 Nejat Seyhun, a professor at the University of Michigan, conducted a study to evaluate anomalous returns tied to insider trading by taking into account the size of the company. He found that insiders in small companies exhibited more purchases than sales. Seyhun also found that insiders generated anomalous returns of 4.3% within the initial 300 days when insiders were net purchasers. He also found that insiders generated anomalous returns of -2.2% in the same duration for companies when insiders were net sellers. He pointed out that adopting intensive trading criteria produced similar outcomes. Seyhun discovered that all types of insiders obtain statistically significant abnormal returns and there is a hierarchy that varies these returns. Seyhun found that major shareholders had the highest returns, and they were followed by officer-directors, and finally officers. His work suggests that insider type, company size, and transaction size are independent factors that influence the anomalous returns of insiders.

In 2001, Lakonishok and Lee conducted a study that analyzed insider trading returns using data from all companies between 1975 and 1995. They also examined how aggregate insider trading could serve as a signal for stock market index movements. They discovered that the net purchase ratio was indicative of insider sentiment. They calculated the net purchase ratio for each month by subtracting sales from purchases and dividing by total insider transactions over 5 years. When the net purchase ratio was in the top quintile, insiders were the most optimistic and the stock market increased by an average of 21.2% during the following 12 months. On the other hand, when the ratio was in the bottom quintile, insiders were the most pessimistic and the stock market returned an average of 8.1% over the next 12 months. This suggests that aggregate insider trading has some predictive power for the future direction of the stock market. Furthermore, Lakonishok and Lee found that companies with extensive insider purchases outperformed those with extensive insider sales by 7.8% over the following 12 months. However, insider purchases were more prevalent in small and high book-to-market companies, while insider sales were more common in larger and low book-to-market companies. When adjusted for size and book-to-market effects, anomalous returns fell to 4.8%. This study indicates that insider trading is more informative in smaller firms.

In 2003, Leslie A. Jeng and Richard Zeckhauser from Harvard University, along with Andrew Metrick from Yale University, computed real returns of insider transactions without consensus data for insider transactions. These researchers calculated returns immediately after an insider executed a transaction, as opposed to when the trade was made public. They did not find a strong correlation between anomalous returns and insider sales, however, they did find a strong correlation between anomalous returns and insider purchases. The raw returns of insider purchases outperformed the market by 11.2% on an annualized basis. When adjusted for book-to-market effects and size, these returns beat the market by 6.4% on an annualized basis.

In 2012 a study conducted by Kaspar Dardas, a research assistant at the European Business School in Wiesbaden, Germany, found a strong correlation between insider transactions and abnormal returns. Dardas sampled European insider transactions between January 2002 and December 2009 from 17 different Western European countries. He found that insider purchase transactions were associated with long-term positive excess returns, while insider sell transactions were associated with long-term negative excess returns. He also developed a method for identifying the most informative insider transactions, categorizing each transaction as a “low conviction”, “medium conviction”, or “high conviction” trade. The results showed that “high conviction” insider purchases generated an average 12-month excess return of 20.94% out-of-sample, while “medium conviction” purchases generated 1.32%, and “low conviction” purchases generated -3.40%.

Insider trading is a controversial practice because it gives an unfair advantage to those who have access to privileged information, and it undermines the integrity of the financial markets. Despite its controversial nature, insider trading has been highly profitable for those who have managed to comply with regulations and engage in it. As pointed out by the studies above, it may be lucrative for outsiders to try to mimic insider behavior by analyzing public information and trading on the same trends as them.

Consensus Criteria Reigns King

Tracking insider trading can be a useful tool for retail investors, but it’s important to note that insider trading alone may not guarantee market-beating returns. As pointed out above, there are multiple independent factors that influence returns on insider trades differently. One of the simplest things investors can do is look at the number of insiders that are buying and compare it to the number of insiders that are selling in order to determine whether to go long or sell short. If a large number of insiders are buying shares of a company, it may indicate that they have a positive outlook on the company’s prospects. The same applies for a large number of insiders selling shares. Investors can look for patterns in insider buying or selling, and check if consensus criteria is met. Additionally, investors can pay attention to significant transactions, such as large purchases or sales of shares, by insiders. These transactions may be indicative of insiders’ confidence in a company’s future performance.
