What Are 10b5-1 Trading Plans?

Why 10b5-1 Plans Exist

The Insider's Dilemma

Consider the position of a chief financial officer at a public company. She knows the quarterly revenue numbers before they are announced. She is aware of pending acquisitions, regulatory developments, and operational problems before the market learns about them. She may be subject to company-imposed blackout periods around earnings releases. Between regulatory blackouts and the continuous flow of confidential information, the windows during which she can trade with certainty that she possesses no material non-public information may be narrow and unpredictable.

This is the insider's dilemma. Section 16 of the Exchange Act permits insiders to trade and requires them to disclose those trades on Form 4 within two business days. Section 10(b) and Rule 10b-5 prohibit trading while in possession of material non-public information. These two provisions coexist, and the boundary between them depends on what the insider knew at the moment of the trade — a fact that can be difficult to establish or disprove after the fact.

The Regulatory Solution

In August 2000, the SEC adopted Rule 10b5-1 to address this tension. The rule established that a person trades "on the basis of" material non-public information if they are aware of it at the time of the trade. But it also created an affirmative defense: if the insider can demonstrate that the trade was made pursuant to a binding contract, an instruction to another person, or a written plan that was established before the insider became aware of the information, the trade is not considered to have been made "on the basis of" that information.

The logic is straightforward. If an insider sets up a plan in March to sell 10,000 shares on the first business day of each quarter, and the company announces unexpectedly poor earnings in June, the July sale still executes. The insider did not make a decision to sell in July — the decision was made in March, when the plan was adopted. The insider's awareness of the earnings results in June does not taint the July transaction because the trading instruction predates the information.

How 10b5-1 Plans Work

Adoption Requirements

To qualify for the affirmative defense, a 10b5-1 plan must satisfy several conditions at the time of adoption:

Good faith. The insider must adopt the plan in good faith, not as part of a scheme to evade insider trading prohibitions. A plan adopted with the intent to cancel or modify it based on future developments does not qualify.

No MNPI. The insider must not possess material non-public information at the time the plan is established. This is the foundational requirement — the plan is designed to separate the trading decision from the information environment, and that separation must be real at the point of adoption.

Specified terms. The plan must specify the amount of securities to be traded, the price at which they will be traded, and the date of the trade. Alternatively, the plan can include a written formula, algorithm, or computer program that determines the amount, price, and date. The insider cannot retain any subsequent influence over how, when, or whether the trades are executed.

Common Structures

In practice, 10b5-1 plans take several forms:

Fixed-date, fixed-amount sales. The most straightforward structure. The plan specifies that the insider will sell a set number of shares on predetermined dates — for example, 5,000 shares on the first trading day of each month for twelve months.

Formula-based sales. The plan provides a formula that determines trade parameters. For example: sell shares equal to 1% of total holdings on the last trading day of each quarter, at the prevailing market price.

Limit orders. The plan specifies that shares should be sold if and when the stock price reaches a particular level. The insider sets the limit at the time of adoption; the broker executes only if the condition is met.

Diversification programs. Common among executives with concentrated positions, these plans sell shares on a regular schedule over an extended period to gradually reduce the insider's exposure to a single stock.

Hands-Off Execution

Once the plan is adopted, the insider steps away. The broker or plan administrator executes trades according to the plan's terms. The insider does not approve individual transactions, does not receive advance notice of specific execution dates (in some arrangements), and does not modify the plan based on subsequent information. If the insider wants to stop selling, they must terminate the entire plan — they cannot selectively skip individual trades while keeping the plan active.

The 2023 SEC Amendments

Rule 10b5-1 operated largely unchanged for over two decades after its adoption in 2000. During that period, academic research and media reporting raised questions about how the rule was being used in practice. Studies documented patterns suggesting that some insiders achieved abnormally favorable execution prices under their 10b5-1 plans, adopted plans shortly before material announcements, or used multiple short-duration plans in rapid succession. In December 2022, the SEC adopted amendments to the rule that took effect in February 2023. These amendments represented the most significant changes to 10b5-1 since its creation.

Cooling-Off Periods

The original rule imposed no waiting period between when a plan was adopted and when the first trade could execute. An insider could adopt a plan on Monday and execute the first trade on Tuesday. The 2023 amendments introduced mandatory cooling-off periods:

• Officers and directors: The first trade under a new or modified plan cannot execute until the later of (a) 90 days after the plan's adoption, or (b) the filing date of the company's next Form 10-Q or Form 10-K. This means the cooling-off period can extend beyond 90 days if no periodic report is filed within that window.
• Other insiders: A 30-day cooling-off period before the first trade.

The cooling-off period addresses concerns that insiders could adopt plans while ostensibly clean but with knowledge of upcoming events that had not yet risen to the level of "material" information. By forcing a delay, the SEC created a buffer between plan adoption and trade execution that reduces the informational advantage of timing plan adoption strategically.

Certification Requirement

Officers and directors must now certify, at the time of plan adoption, that (a) they are not aware of any material non-public information about the company or its securities, and (b) the plan is being adopted in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5. This certification requirement makes the insider's representations explicit and documented, rather than implicit.

Single-Trade Plan Restrictions

Before the amendments, an insider could adopt a plan covering a single trade, execute that trade, terminate the plan, and adopt a new single-trade plan shortly afterward. Critics argued this pattern — sometimes called "serial single-trade plans" — allowed insiders to replicate discretionary trading under the protective label of a 10b5-1 plan. The 2023 amendments restrict insiders to one single-trade plan per 12-month period. An insider who wants to make multiple trades must adopt a plan that covers all of them, with the full cooling-off period applying.

Multiple Overlapping Plans Prohibited

The amendments generally prohibit maintaining multiple overlapping 10b5-1 plans for open-market transactions in the same class of securities. An insider cannot maintain two active plans simultaneously and switch between them based on which produces more favorable results. Limited exceptions exist — for example, a plan to sell shares and a separate plan to exercise options may coexist under certain conditions.

Enhanced Disclosure Requirements

The 2023 amendments strengthened disclosure obligations at both the individual and company levels. Form 4 filings must indicate whether a reported transaction was made pursuant to a Rule 10b5-1 plan. Companies must disclose, in their quarterly and annual reports (10-Q and 10-K filings), the adoption and termination of 10b5-1 plans by their officers and directors, including the date of adoption, the duration of the plan, and the aggregate number of securities covered.

Gift Restrictions

Before the amendments, bona fide gifts of securities were not subject to the same restrictions as sales. The SEC observed that this created a potential loophole: an insider aware of negative information could gift shares to a charity (receiving a tax deduction at the current market value) before the information became public and the stock price declined. The 2023 amendments closed this gap by bringing gifts of securities within the scope of the rule when the insider is aware of material non-public information.

10b5-1 on Form 4

When you encounter a Form 4 filing on SEC EDGAR, one of the fields indicates whether the reported transaction was executed pursuant to a Rule 10b5-1 trading plan. This checkbox appears in the filing and is reflected in the structured data available through EDGAR.

A checked 10b5-1 box means the insider has represented that the trade was part of a pre-arranged plan adopted at a time when they did not possess material non-public information. It does not mean the trade is insignificant or uninteresting — it means the decision to trade was made at an earlier date under different information conditions than those prevailing at the time of execution.

Many Form 4 filings also include footnotes that describe the terms of the 10b5-1 plan. These footnotes often specify when the plan was adopted, what triggers the trades, and whether the plan covers a fixed schedule or uses a formula. Reading the footnotes can provide substantially more context than the checkbox alone. For example, a footnote might reveal that a plan was adopted six months before the reported trade, or that the plan covers sales over a two-year period — details that are not visible from the checkbox field.

The absence of a 10b5-1 indication means the trade was discretionary. The insider chose to buy or sell at that specific time, under the market conditions and information environment that existed on that date. Both planned and discretionary trades are lawful (assuming no MNPI possession for discretionary trades), but the distinction between them represents a meaningful difference in context.

How Akivus Uses This Data

The Akivus significance scoring system includes "10b5-1 Plan Status" as one of its eight scoring factors. The system reads the 10b5-1 indicator from each Form 4 filing and uses it to assess the contextual characteristics of the transaction.

Trades executed under a 10b5-1 plan may have their significance score suppressed. The reasoning is structural: a pre-arranged trade was decided at some earlier point in time, potentially months before execution, and reflects the insider's financial planning rather than a response to current company developments. A sale that executes in August under a plan adopted in February does not carry the same contextual characteristics as a discretionary sale initiated in August. The Akivus scoring system treats this difference as a relevant factor when evaluating the overall context of a transaction.

This suppression is not a judgment about the importance of planned trades. Many planned trades are made by senior executives with deep knowledge of their companies, and the adoption of a plan is itself a decision that reflects the insider's assessment at the time of adoption. The scoring system simply distinguishes between trades where the insider exercised discretion at the time of execution and trades where the execution followed a predetermined schedule. When the Akivus scoring system applies suppressors — factors that reduce a score — it gives them priority over promoters, reflecting a conservative approach to contextual assessment. The score describes characteristics of the trade's context as reported in public filings. It does not predict stock price movements, express a view on the company's prospects, or constitute a recommendation of any kind.
