What is Insider Trading?

Definition and Background

Insider trading refers to the practice of trading shares or other securities of a company on the basis of non-public and confidential information about the company. This behavior is considered unethical and illegal because it provides an unfair advantage over other investors who do not have access to this information.

Examples of Insider Trading

1. Stock trading:

An executive of a company who knows that the company is going to be acquired and, before the public announcement, buys large quantities of the company’s shares.

2. Financial information

An employee of the finance department who has access to the quarterly results before their public release and decides to sell his shares knowing that the results will be negative.

3 . Mergers and acquisitions:

A consultant working on an impending merger between two large companies and buying shares in both before the official announcement.

How does insider trading work?

Mechanisms and Methods

Insider trading can occur in various ways, involving different actors and circumstances. Some of the most common forms include:

1. Inside Information:

Employees who have access to critical information about the company.

2. External information:

Consultants, auditors or lawyers who obtain inside information through their work.

3.  Disclosure of information:

People who obtain information illegally through wiretapping, hacking or other espionage activities.

Information chain

1. Primary source:

Inside information is generated within the company (e.g. financial reports, expansion plans).

2. Dissemination:

Information is shared with a small group of people who are in a position of trust.

3.  Action:

One or more of these persons use the information to make investment decisions before the information becomes public.

Legislation and Legal Consequences

Laws and Regulations

The practice of insider trading is regulated by specific laws that vary from country to country, but which generally share a common goal: to protect the fairness and transparency of the financial markets. In Portugal, the CMVM (Portuguese Securities Market Commission) is the entity responsible for supervising and regulating the securities market.

Legal consequences

1. Heavy fines

Significant financial penalties.

2. Imprisonment:

In serious cases, can result in a prison sentence.

3. Loss of professional licenses:

Professionals involved may lose their licenses and ability to work in the financial sector.

The Importance of Fighting Insider Trading

Market Integrity

Trust in financial markets is fundamental to their proper functioning. When investors believe that everyone has the same opportunities and that the market is fair, they are more willing to invest.

Protecting Investors

Insider trading harms ordinary investors, who don’t have access to the same information. Fighting this practice helps protect the interests of these investors and maintain a fair investment environment.

Economic Stability

Transparent and fair financial markets contribute to global economic stability. Insider trading can lead to crises of confidence, destabilize markets and damage the economy.

Detailed Answer to the Challenge Question

Now, let’s answer the question we posed earlier:

What is the main legal consequence for someone convicted of insider trading?

The main legal consequence for someone convicted of insider trading can vary, but generally includes heavy fines and, in many cases, prison sentences. In addition, the convicted person may face additional sanctions, such as a ban on activities in the financial market and the loss of professional reputation.

How can I report insider trading?

Reporting channels

If you suspect insider trading, it is important to report it. In Portugal, you can contact the CMVM or other competent authorities. Reports can often be made anonymously.

Whistleblower protection

To encourage reporting, many jurisdictions offer legal protection to whistleblowers, ensuring that they do not face retaliation for reporting illegal activities.


Insider trading is a serious practice that undermines integrity and trust in the financial markets. It is crucial that everyone, from investors to industry professionals, understands the importance of fighting this practice. Only through continuous vigilance and strict enforcement can we guarantee a fair and equitable investment environment for all.
