Introduction: What is Insider Trading?
Insider trading is a term that evokes both intrigue and controversy in the financial world. It refers to the buying or selling of a company’s securities by someone who has access to non-public, material information about the company. While the term often carries a negative connotation, not all insider trading is illegal.
In this blog, we’ll break down the concept of insider trading, distinguish between legal and illegal practices, and explore its implications for investors and the stock market.
Legal Insider Trading: When is it Allowed?
Contrary to popular belief, insider trading can be perfectly legal under specific conditions. For instance:
- Corporate Insiders Trading Publicly Disclosed Information: When company executives, employees, or directors trade their own company’s stocks after properly disclosing their trades to the stock exchange, it’s considered legal.
- Adherence to Regulatory Guidelines: SEBI (Securities and Exchange Board of India) requires insiders to report their trades and avoid trading during designated blackout periods.
Example of Legal Insider Trading:
In July 2022, a senior executive at Reliance Industries disclosed their purchase of shares in accordance with SEBI’s guidelines. This was legal because it followed all required disclosures and was not based on unpublished material information.

Illegal Insider Trading: Crossing the Line
Illegal insider trading occurs when someone trades securities based on non-public, material information that gives them an unfair advantage. This practice is considered unethical and is punishable under law.
Key Characteristics of Illegal Insider Trading:
- Use of Material Non-Public Information (MNPI): Trading based on information that has not been disclosed to the public and could influence stock prices.
- Unfair Advantage: Gaining an edge over other investors who lack access to the same information.
- Violation of Trust: Breaching a fiduciary duty or confidentiality agreement.
Examples of Illegal Insider Trading:
- In 2020, SEBI penalized an employee at Infosys for sharing sensitive earnings data with a trader before its official announcement.
- The high-profile case of Rajat Gupta, a former Goldman Sachs director, who leaked confidential information to a hedge fund manager, led to significant penalties and imprisonment.
How Insider Trading is Regulated in India
The SEBI (Prohibition of Insider Trading) Regulations, 2015, governs insider trading in India. Key provisions include:
- Prohibition on Trading MNPI: Insiders are barred from trading or sharing non-public, material information.
- Disclosure Requirements: Insiders must disclose their trades, including acquisitions or disposals of securities, beyond a specified threshold.
- Trading Windows and Blackout Periods: Companies establish specific trading windows during which insiders are allowed to trade, while blackout periods restrict trading around critical announcements.

The Impact of Insider Trading on the Market
1. Erosion of Investor Trust
Illegal insider trading undermines market integrity, leading to distrust among retail investors.
2. Market Inefficiency
When insiders exploit non-public information, it disrupts the level playing field and distorts stock prices.
3. Legal Repercussions
Regulators impose hefty fines and imprisonment for offenders, serving as a deterrent for potential violators.
How Can Retail Investors Protect Themselves?
- Stay Informed: Monitor disclosures by company insiders, which are publicly available on stock exchange websites.
- Diversify Investments: Reduce risk by diversifying your portfolio across different sectors and asset classes.
- Be Cautious of Sudden Price Movements: Unusual spikes in stock prices without any apparent reason could indicate insider activity. Wait for official announcements before making decisions.
