Insider Trading Activity (Form 4 Filings)

Corporate insiders such as executives, directors and major shareholders may buy or sell shares of companies with which they are affiliated. These transactions can give investors another way to monitor changes in insider ownership, but a purchase or sale does not by itself explain why the insider traded or predict where the stock is headed.

MarketBeat's Insider Trading Activity tracker brings together recently reported insider purchases and sales and shows details such as the insider's role, transaction size, transaction date and shares held after the transaction. Investors can use the data to look for patterns such as repeated purchases, multiple insiders trading around the same period or unusually large changes in ownership.

For U.S. companies, many transactions by officers, directors and shareholders who own more than 10% of a class of registered equity securities are reported through SEC Forms 3, 4 and 5. Most reportable transactions appear on Form 4 within two business days after the transaction.

MarketRank™ evaluates a company based on dividend strength, earnings, valuation, analysts forecasts, and more.

Frequently Asked Questions

An insider trade is a purchase, sale or other change in ownership involving a company insider, such as certain officers, directors or major shareholders. These transactions are not inherently illegal.

For U.S. public companies, many insider trades subject to Section 16 reporting requirements are disclosed to the SEC on Forms 3, 4 or 5.

For U.S. securities reporting purposes, company insiders generally include a company's officers and directors, as well as shareholders who own more than 10% of a class of the company's registered equity securities. These insiders are subject to specific SEC reporting requirements for their ownership and transactions.

The term does not mean that every insider has material nonpublic information whenever they trade. Insiders can legally buy and sell company securities as long as they comply with applicable securities laws and company policies.

The term "insider trading" can refer to two different types of activity.

It can describe legal transactions in which company insiders, such as executives and directors, buy or sell their company's securities and comply with applicable reporting requirements and trading rules.

It can also refer to illegal trading based on material, nonpublic information in violation of a duty or other relationship of trust and confidence. For example, an executive generally cannot trade based on significant company information that has not yet been made public.

Form 4 is an SEC filing used to report many changes in beneficial ownership by certain officers, directors and shareholders who own more than 10% of a class of a company's registered equity securities.

It can report purchases and sales as well as transactions involving options, awards and other securities. Investors should therefore look beyond a simple "buy" or "sell" label when a transaction requires additional context.

Most reportable Form 4 transactions must be disclosed within two business days of the transaction.

That means the transaction date and the date investors first see the filing may differ. A trade appearing in the tracker today may have occurred one or more business days earlier.

It shows the number of shares attributed to the insider after the reported transaction. Comparing that figure with the number of shares bought or sold can help put the transaction into perspective.

For example, selling 10,000 shares may have different significance for an insider who retains 1 million shares than for one who sells most of a position.

No. An insider purchase shows that the insider increased an ownership position, but it does not establish why the purchase was made or predict future stock performance.

Investors can look for additional context, including the size of the purchase relative to the insider's existing holdings, whether several insiders are buying and how the activity compares with the company's financial results and other disclosures.

Not necessarily. Insiders may sell shares for many reasons unrelated to their view of the company, including diversification, taxes, personal financial needs or transactions made under a predetermined trading plan.

A series of sales can still be worth investigating, particularly when several insiders reduce significant portions of their holdings, but the filings and surrounding circumstances provide more useful context than the sale alone.

A Rule 10b5-1 plan can allow an insider to establish predetermined conditions for future trades at a time when the person is not aware of material nonpublic information. If the plan meets the rule's requirements, it can provide an affirmative defense to insider-trading liability.

Current SEC rules include cooling-off periods and other conditions intended to prevent insiders from using these plans opportunistically. Investors may find disclosures about trading plans useful when evaluating the context surrounding insider sales.

The transaction date reflects when the reported trade occurred, while the reporting or filing date reflects when information about it was disclosed.

For U.S. Form 4 transactions, the filing deadline is generally two business days after the transaction, so a short delay between those dates is normal.

Not generally. Form 4 is part of the U.S. securities-disclosure system. Canada and the United Kingdom have their own insider and director transaction reporting requirements.
