What is insider trading?

Insider trading refers to buying or selling stocks based on confidential information unavailable to the general public. When government officials trade stocks, they potentially use inside information gained from their positions, which gives them an advantage over regular investors. While some instances of government-related insider trading are legal, the optics raise questions about fairness and integrity.

In the past, Congress and federal officials have had the privilege to trade stocks, but public scrutiny and criticism have led to legal changes over the years. In 2012, the US passed the Stop Trading on Congressional Knowledge (STOCK) Act, aiming to prevent insider trading by members of Congress and federal employees. However, certain loopholes and minimal enforcement mean insider trading remains a hot topic.

In July 2024, Paul Pelosi, Nancy Pelosi’s mentioned husband, sold between $500,000 and $1 million worth of Visa (NYSE: V) stock.

  2. Richard Burr’s stock dump: In February 2020, Senator Richard Burr sold between $628,000 and $1.72 million in stocks across 33 transactions.

  1. David Perdue’s defense contracts: Senator David Perdue made significant stock purchases in a company that held government defense contracts.

  1. Wilbur Ross and his interests in shipping: As Secretary of Commerce, Wilbur Ross retained investments in shipping companies, including Navigator Holdings (NYSE: NVGS), valued between $2 million and $10 million.

How insider trading regulations affect government officials

Though the STOCK Act was a major step forward, its limitations make it difficult to enforce strict insider trading policies. Like most acts, it’s full of weaknesses, and the ones that draw the most attention are:

  • Weak penalties: Fines are low and don’t necessarily deter high-income officials;
  • Disclosure delays: Public disclosure of trades can take up to 45 days, by which time the market impact of these trades often fades;
  • Complex reporting: The STOCK Act requires specific reporting procedures, which many officials reportedly struggle to follow accurately.

How do large trades get attention?

Here are some common triggers that bring large trades under public scrutiny:

  • Timing of the trade: When trades coincide with major events, such as a pandemic or policy change;
  • Volume of shares: Large transactions that suggest a significant stake in a company;
  • Type of company: Companies closely affected by government policy or contracts, especially in defense, healthcare, and tech.

Congressional insider trading during the COVID-19 pandemic

In early 2020, as COVID-19 began to spread globally, a congressional insider trading scandal erupted, putting the spotlight on several US lawmakers.

Both Republican and Democrat Senators and representatives faced allegations of selling large amounts of stock just before the pandemic caused a market crash. These officials had received closed-door briefings about the severity and potential impact of the virus on the US, prompting concerns that they used non-public information to avoid financial losses.

Among the most scrutinized trades were those by Senators Richard Burr, Kelly Loeffler, and Dianne Feinstein, who each made substantial transactions following confidential briefings.

A study by Thomas Bauer explored the trading activities of US Representatives during the COVID-19 pandemic. The study analyzed whether US lawmakers used non-public information to gain financial advantages by examining their stock returns during the crisis. Bauer investigated the timing and outcomes of their trades to determine if members of Congress benefitted from insider knowledge before the general public.

Bauer’s findings suggest that while some trades have raised public concern, there may not be conclusive evidence that insider trading was prevalent among lawmakers during this period.

“This thesis finds little evidence of widespread insider trading in the US House of Representatives during the COVID-19 pandemic.”

The bottom line

Insider trading in government raises key questions about fairness and trust. While regulations like the STOCK Act aim to increase transparency, certain gaps remain, and the public’s engagement is key to holding officials accountable. Nevertheless, tracking tools like Finbold Signals can provide you as an investor with the ability to stay informed and follow major movements by big players like US politicians.

FAQs

Insider trading involves buying or selling stocks based on confidential information not available to the public. When government officials trade stocks based on inside information gained from their roles, it creates an unfair advantage over regular investors and can undermine public trust.

What are the regulatory rules for insider trading?

The Stop Trading on Congressional Knowledge (STOCK) Act of 2012 requires government officials to disclose their trades within 45 days. However, critics argue that its penalties are weak, and delayed disclosures make it difficult to prevent potential abuses.

Is the US government allowed to buy stocks?

Yes, government officials are permitted to buy stocks, as long as they follow regulations. However, they must disclose their trades within 45 days under the STOCK Act, and avoid trading based on insider information that isn’t available to the public.

What is the STOCK Act?

The STOCK Act mandates disclosure of trades made by Congress members and other federal employees to prevent insider trading. While it’s a significant step toward transparency, limited penalties and delays in reporting have raised questions about its effectiveness.

Who enforces the STOCK Act?

The US Office of Government Ethics (OGE) oversees compliance with the STOCK Act for executive branch officials, while the US House and Senate Ethics Committees handle enforcement for Congress members. These bodies review trade disclosures, though enforcement has been criticized for its limited effectiveness and light penalties.

Can government officials use insider knowledge to trade stocks?

No, using insider knowledge to trade stocks is illegal for government officials, just as it is for corporate insiders. However, enforcement challenges make it difficult to prove when officials use confidential information to make trades, so controversies still arise.

How do large stock trades by government officials get flagged?

Large trades typically attract attention if they coincide with significant policy events, involve high share volumes, or include companies closely tied to government actions, such as defense or healthcare.
