How to Spot the 10b5‑1 Checkbox on a Form 4 Filing
Learn where the 10b5‑1 box appears on SEC Form 4, what a pre‑programmed trade means, and how to follow its execution using free public data.
The 10b5‑1 checkbox appears in the top‑right corner of the Form 4, next to the filing type box. It is a small square labeled “10b5‑1” that the insider may tick when a trade is executed under a pre‑established plan. Seeing the box checked tells you the transaction was not a discretionary decision made at that moment.
Below we explain how to read the box, what a pre‑programmed trade entails, and how to follow its execution through subsequent filings. We also show how to compare the information with Form 13F and STOCK Act disclosures, giving retail investors a clear workflow for monitoring insider activity.
Key takeaways
- The 10b5‑1 checkbox is located in the transaction details section of Form 4.
- A checked box signals a pre‑arranged trade that complies with Rule 10b5‑1.
- Investors can monitor subsequent filings to see if the plan is being carried out.
- Free tools let you set alerts for future Form 4 submissions by the same insider.
Finding the 10b5‑1 Box on Form 4
Open the filing on the SEC EDGAR site. After you click the “Documents” button, choose the primary filing (usually a .htm file) and scroll until the “Transaction” table appears.
The table records each trade the insider reported. Common columns are Date, Transaction Code, Amount of Securities, Price, and Aggregate Amount. Look for a column labeled 10b5‑1 or a small checkbox placed beside each transaction line.
| Column header | What you see |
|---|---|
| 10b5‑1 | A box that can be checked (✓) or left blank |
A checked box means the trade was executed under a pre‑approved 10b5‑1 plan. An empty box indicates the transaction was not part of such a plan.
To confirm you are looking at the correct row, compare the entry with the “Transaction Code” column. A code of “P” (Purchase) or “S” (Sale) will have the same 10b5‑1 indicator next to it.
When you locate a checked box, you can scroll down to the “Notes” section of the same filing for any remarks the insider added. For a step‑by‑step example, see our guide on how to spot the 10b5‑1 checkbox on a Form 4 filing.
What a Pre‑Programmed Trade Means
A 10b5-1 plan serves as a pre-authorized trading instruction for a broker. The insider determines the purchase or sale timing well in advance of execution, months before any actual trade occurs. This arrangement creates a legal defense against insider trading allegations.
To establish this defense, the insider must create the plan while lacking material non-public information. They cannot rely on upcoming earnings surprises, pending mergers, or undisclosed product failures when signing the paperwork. The plan records the insider's intent at a time when no unfair advantage exists over the public market.
SEC rules impose specific requirements to maintain the plan's validity:
- Cooling-off Period: The plan must be established at least 30 days before the first trade. This delay prevents the insider from acting on immediate private data.
- No Intervention: Once active, the insider cannot influence the trade. They cannot contact their broker to cancel a sale based on a short-term price expectation.
- Automatic Execution: A broker follows the pre-set parameters. When the stock reaches the target price on the scheduled date, the trade executes automatically.
Retail investors should interpret these trades differently from discretionary ones. A checked box indicates the insider made the decision in advance. It does not reflect their opinion on current company news. The trade follows a script created when the insider had no special knowledge of ongoing events.
Tracking the Plan’s Execution
After the first filing, monitor any subsequent Form 4 submissions from the same insider that involve the same security.
| What to look for | Why it matters |
|---|---|
| Filing date - a later Form 4 after the original | Shows when the scheduled trade actually took place. |
| Transaction amount - shares bought or sold, price, total value | Lets you verify that the trade aligns with the size and timing described in the 10b5‑1 plan, if the insider provided those details. |
| Transaction type - purchase, sale, or disposition | Confirms the direction of the trade and helps you see whether the plan is being applied consistently. |
If the insider disclosed plan parameters in an earlier Form 4 or an accompanying 8‑K, compare those numbers with the new filing. A discrepancy may mean the plan was altered or that a separate, unrelated trade occurred.
To avoid repeatedly checking the page, use Bourse’s alert feature. Add the insider’s name or ticker to your watchlist, and the system will email you as soon as a new Form 4 is posted. The notification lets you record the trade, update your spreadsheet, and keep a precise timeline of the insider’s activity.

Cross‑Checking with Other Filings
A Form 4 works best when you compare it to other SEC filings. Start with Form 8-K. Companies use this form to report major events like mergers or leadership changes. If an insider sells shares under a 10b5-1 plan right after an 8-K, the news might have triggered a price limit in their plan. You can see if the trade happened because the stock hit a specific price target mentioned in past company updates.
Next, look at Form 13F filings. These reports show what large investment managers own. Many corporate directors also run private equity firms or hedge funds. Check the 13F to see if the insider’s personal trade matches what their fund is doing. This helps you see if a sale is just for personal cash or if the insider’s firm is also moving away from the stock.
Always read the footnotes at the bottom of the Form 4. While the checkbox confirms a plan exists, the footnotes give you the facts. These notes usually list the date the insider adopted the plan. You should study the Form 4 footnotes to find these details. SEC rules require insiders to disclose these dates to show when they committed to the trade.
| Filing Type | What to Look For |
|---|---|
| Form 8-K | Corporate news that might trigger a price limit in a plan. |
| Form 13F | Whether the insider’s fund is buying or selling the same stock. |
| Form 4 Footnotes | The specific date the insider adopted or modified their plan. |
Practical Steps for Retail Investors
Maintain a spreadsheet to track insider activity. Record the insider’s name, the ticker, and the trade date for every Form 4 you review. Add a specific column for the 10b5-1 checkbox. This checkbox confirms if the executive scheduled the trade in advance. A checked box means the insider committed to the sale or purchase months earlier to avoid conflicts with non-public information.
Monitor the stock price for several weeks after the filing. Record whether the price rises, falls, or stays flat. Scheduled trades often occur regardless of current market volatility or upcoming earnings reports. Tracking these filings over time helps you identify patterns in how executives manage their equity.
| Tracking Column | Purpose |
|---|---|
| 10b5-1 Status | Distinguishes planned trades from discretionary ones |
| Trade Date | Sets the start point for price tracking |
| Shares Held | Shows the insider's remaining stake in the company |
View the 10b5-1 checkbox as one data point in your analysis. You should research a stock with public filings to compare these trades with company earnings and debt levels. Do not assume a pre-programmed sale predicts a price drop. Executives frequently sell shares to cover tax obligations, pay for tuition, or diversify their personal wealth. Use this data to build a broader picture of company activity. This method keeps your analysis focused on objective facts rather than speculation.
FAQ
Where is the 10b5‑1 checkbox located on a Form 4?
The 10b5‑1 checkbox appears on the first page of Form 4, directly beneath the table of transaction details. It is positioned next to the “Transaction Code” column and is labeled “10b5‑1” so insiders can mark it when the trade follows a pre‑established plan.
Does a checked 10b5‑1 box guarantee the trade was legal?
A checked 10b5‑1 box does not guarantee legality. It indicates the insider claims the transaction was executed under a written trading plan filed before the trade. Regulators still evaluate whether the plan complied with insider‑trading rules and whether the insider had material non‑public information at the time.
How soon after a 10b5‑1 trade must the insider file Form 4?
Insiders must file Form 4 within two business days after the trade, regardless of whether the transaction was made under a 10b5‑1 plan. The filing deadline is the same for all equity transactions reported on Form 4, and the 10b5‑1 box simply provides additional context.
Can I set up alerts for future 10b5‑1 trades by the same insider?
Yes, you can set up alerts on most insider‑tracking platforms to notify you when a specific insider files a Form 4 with the 10b5‑1 box checked. Choose the insider’s name or CIK, enable the “10b5‑1” filter, and the system will email or push a notification each time a new filing appears.
