The Difference Between Legal and Illegal Insider Trading

By Hager & Schwartz, P.A.

February 23, 2025

Insider trading refers to buying or selling stocks, bonds, or other securities based on material, non-public information—details that could affect a company’s stock price but are not yet accessible to the public. Corporate insiders, such as executives, employees, or stakeholders, acting on exclusive knowledge can create an unfair advantage, undermining trust in financial markets. However, not all insider trading is illegal. The distinction between legal and illegal trading depends on disclosure, intent, and timing.

Understanding the legal boundaries is crucial because the consequences of illegal insider trading, a serious white collar crime, can be severe. A single misstep can lead to SEC investigations, civil penalties, and even federal criminal charges, potentially resulting in prison time. For professionals in finance, corporate leadership, or investing, these risks highlight the importance of complying with federal regulations. The Securities and Exchange Commission (SEC) strictly enforces these laws to maintain market integrity, ensuring that all institutional or individual investors operate on a level playing field.

If you or a loved one is facing allegations of insider trading, having skilled legal representation can make a significant difference. At Hager & Schwartz, P.A., we know the complexities of these charges and the personal and professional stakes involved. Our experienced white collar crime attorneys provide strategic counsel to protect your rights and advocate for your future.

What Is Insider Trading?

Insider trading occurs when a corporate insider buys or sells a company’s securities. While the term often carries a negative connotation, insider trading is not inherently illegal. The distinction between lawful and unlawful activity depends on whether the trading party had a duty to keep the information confidential and whether the trade was properly disclosed under regulatory guidelines.

A corporate insider typically has privileged access to a company’s financial and strategic operations. Insiders include senior executives, board members, and high-ranking employees with decision-making authority. However, corporate insiders are not confined to company leadership; anyone who owns more than 10% of a publicly traded company’s voting shares is also considered an insider under federal securities laws.

The role of material information is central to insider trading cases. Material information refers to data that could significantly influence a company’s stock price or affect an investor’s decision to buy or sell shares. This information may include earnings reports, mergers and acquisitions, executive changes, or regulatory investigations. If this information is not publicly available and used to gain a financial advantage, it could lead to serious legal consequences.

While insider trading is often linked to corporate scandals and regulatory crackdowns, not all instances are illegal. Legal insider trading happens when corporate insiders—such as executives, board members, or major shareholders—buy or sell their company’s stock following federal regulations. These transactions are permitted if they are appropriately disclosed and occur within specified timeframes to avoid unfair advantage.

To ensure fairness in the stock market, companies must follow SEC regulations and establish clear corporate compliance guidelines for insider trading. These policies outline disclosure requirements, trading windows, and safe harbor rules to prevent illegal activity.

Transparency Through Disclosure and Trading Windows

The SEC has established strict disclosure requirements and trading windows for insiders to ensure fair market practices. Legal insider trading must be transparent, allowing the public and investors to see when executives or key stakeholders make stock trades.

Corporate insiders can only buy or sell company shares during specific trading windows. These windows are pre-approved periods after prominent financial disclosures, such as earnings reports. The windows help prevent the use of material non-public information for personal gain. Additionally, insiders must file Form 4 with the SEC within two business days of executing a trade. This form publicly discloses the transaction, allowing investors and regulators to monitor insider activity.

Safe Harbor Rules: Pre-Planned Trades Under SEC Rule 10b5-1

One of the most effective ways for corporate insiders to legally trade company stock without the risk of violating securities laws is through Rule 10b5-1 trading plans. This SEC regulation provides a safe harbor by allowing insiders to set up pre-arranged trading agreements when they do not possess material non-public information.

A valid 10b5-1 plan must meet specific requirements:

  • It must be established when the insider cannot access confidential or non-public financial data.
  • The plan must predetermine key trade details, including stock price, volume, and transaction dates.
  • Once in place, trades must be executed according to the plan—insiders cannot make discretionary changes based on new information.

By adhering to these legal safeguards, corporate insiders can engage in stock transactions without raising concerns about insider trading violations. However, regulatory scrutiny remains high, and even well-intentioned trades can trigger SEC investigations.

Illegal Insider Trading. What’s Not Allowed?

Illegal insider trading occurs when an individual buys or sells securities based on material non-public information (MNPI) to gain an unfair advantage in the market. Unlike legal insider trading, which follows strict disclosure and compliance guidelines, illegal trading involves using confidential company data not available to the general public to make profitable trades before the information is widely known.

For a trade to be considered illegal insider trading, it must meet certain legal criteria:

  • The trader had access to MNPI. This information includes confidential financial reports, earnings forecasts, merger negotiations, or regulatory investigations.
  • The information was not yet available to the public. If the average investor does not have access to this data, using it for stock transactions is unlawful.
  • The individual knowingly used the information for personal gain. This applies whether the trader is a corporate executive, employee, or even a third party who received a tip from an insider.

Illegal insider trading isn’t just restricted to corporate executives. Friends, family members, brokers, or any individuals who tip off someone with insider knowledge can also be held responsible under securities laws. Even if an insider doesn’t personally trade but shares confidential information with another person who profits from it, both parties can be prosecuted.

The SEC’s Role in Detecting and Investigating Insider Trading

The SEC actively monitors financial markets for suspicious trading activity. Unusual stock movements, such as large, unexplained trades occurring just before a major corporate announcement, can trigger investigations.

When the SEC detects irregular trading patterns, it conducts a thorough inquiry, examining trading records, emails, phone calls, and other forms of communication. Investigators work alongside the Department of Justice (DOJ) and other regulatory bodies to determine whether securities law violations have occurred.

Illegal insider trading is considered a serious offense, carrying civil and criminal penalties:

  • SEC civil enforcement actions may result in hefty fines, disgorgement of profits, and trading bans.
  • Criminal prosecution under 18 U.S.C. § 1348 (securities fraud) can lead to lengthy prison sentences, often up to 25 years, and substantial financial penalties.
  • Convictions can permanently damage a person’s career and reputation, particularly those in finance, corporate leadership, or investment industries.

What to Do if You’re Accused of Insider Trading

Insider trading allegations can have serious legal and financial consequences, including SEC investigations, steep fines, and criminal charges. Because these cases involve complex securities laws and federal regulations, having an experienced white collar crime lawyer is crucial. The SEC and DOJ aggressively pursue insider trading violations, often using trading records, emails, and financial transactions as evidence. A strong legal defense can help challenge the prosecution’s claims, negotiate reduced penalties, or seek case dismissal.
