In the business/finance sector, the term ‘insider’ is of significant importance because it refers to an individual who has access to sensitive, non-public information about a publicly-traded company or corporation. This can include corporate officers, directors, shareholders, employees, and even relatives of these individuals. Insiders are subject to strict trade regulations to protect against insider trading – the illegal practice of trading based on non-public information. The actions and behavior of insiders can provide crucial insights into a company’s operations, financial health, and potential future moves. For this reason, monitoring insider behavior is considered important by investors and regulatory bodies.


In the world of finance and business, an insider plays a crucial role in helping an organization orchestrate their strategies effectively, capitalize on opportunities, and mitigate risks. Essentially, an insider is anyone who possesses access to valuable non-public information about a corporation. Often times, they are company’s key officials – such as directors, top-level executives or employees who can leverage this privileged information to influence strategic decisions. These decisions could encompass a wide spectrum including operations, mergers, acquisitions, and financial planning, and can have a profound impact on the company’s performance, profitability, and stock prices.In many instances, insiders hold a significant amount of the company’s shares, influencing stock market trends as they have the power to take investment decisions based on the exclusive information at their disposal. Thereby, their actions often serve as a barometer for the company’s future prospects, signaling the market on potential stock price movements. However, it’s crucial to note that insider trading—buying or selling stocks based on privileged information—is heavily regulated and often illegal without proper disclosure, due to the potential for market manipulation and unfair advantages. Therefore, the role of an insider, while influential, needs to operate under a stringent regulatory framework to maintain market integrity and fairness.


1. Martha Stewart’s Insider Trading Case: Among the most famous cases of insider trading is that of Martha Stewart, a successful businesswoman and television personality. In 2001, she sold all of her stocks in the biopharmaceutical company, ImClone Systems, based on an illegal tip she received from her broker. The tip suggested that the FDA was about to deny approval of one of ImClone’s drugs, which would have led to the company’s stock prices falling.2. Galleon Group Insider Trading: The American hedge fund group Galleon was at the center of a huge insider trading scandal uncovered in 2009. Its founder, Raj Rajaratnam, was charged with making $63.8 million in illicit profits by trading on insider information from executives at several major companies like Intel, IBM, and Google. 3. The ENRON Scandal: Another famous case of insider trading took place at Enron, a US energy company, in 2001. As the company was nearing bankruptcy, executives who knew the true state of the company’s finances sold off their stock and made vast profits, while shareholders and employees were left with worthless investments. This use and abuse of insider information led to one of the largest corporate bankruptcies in U.S. history.
