Form 144 must be filed with the SEC when an affiliate (insider or large shareholder) intends to sell restricted or control securities in the public market. It provides advance notice of planned sales, helping traders anticipate potential selling pressure.
While Form 4 reports sales after they happen, SEC Form 144 is filed before an affiliate sells restricted or control securities. It gives the market a heads‑up that a large or insider shareholder plans to sell, often within 90 days of filing.
Why it matters for traders – A flurry of Form 144 filings can signal upcoming supply overhang. Conversely, a lack of Form 144 filings after a lock‑up expiry may indicate insiders are holding – a subtle bullish sign.
| Term | Definition | Example |
|---|---|---|
| Restricted securities | Shares acquired in private placements, Regulation D offerings, or employee stock plans not registered with the SEC | Venture capital shares, pre‑IPO stock, PIPE deals |
| Control securities | Shares owned by an affiliate (director, officer, or 10%+ shareholder) of the company – even if purchased on the open market | A CEO buying shares on Robinhood still holds control securities |
Both types cannot be freely resold without either registration (a full S‑1) or an exemption. Rule 144 provides the most common exemption.
Exception – Non‑affiliate holders of restricted securities who have held for at least 6 months (or 1 year for shell companies) and meet other conditions do not need to file Form 144.
To sell under Rule 144 without registering, the seller must satisfy:
| Section | Information Provided |
|---|---|
| Issuer | Company name, address, CIK, ticker |
| Person filing | Name, address, relation to issuer (affiliate status) |
| Securities to be sold | Class, number of shares, aggregate market value |
| Broker / market maker | Name of the brokerage executing the sale |
| Nature of transaction | Open market, block trade, or other |
| Date of proposed sale | A future date (or "as soon as practicable") |
| Number of shares owned after sale | Remaining holdings |
| Footnote disclosure | Rule 144 conditions met, any prior sales in last 3 months |
Note: Form 144 is not a notice of execution. It is a notice of intent to sell, sometimes filed weeks before any trade occurs.
Example: An insider wants to sell 100,000 shares on September 10. She must file Form 144 on September 9 or the morning of September 10 before trading. The filing remains active until December 9.
If the proposed sale equals 50% of average daily volume, expect selling pressure over several days. A small sale (e.g., 5,000 shares in a Nasdaq large‑cap) is noise.
Multiple Form 144 filings from different affiliates on the same day or week → possible coordinated selling or lock‑up expiry. This can create a temporary overhang.
Insiders selling near 52‑week highs is normal (profit taking). Selling near 52‑week lows raises a yellow flag – why sell at the bottom?
| Aspect | Form 144 | Form 4 |
|---|---|---|
| Timing | Before the sale (notice of intent) | After the sale (within 2 business days) |
| Who files | Affiliates selling restricted/control securities | All insiders (including 10% owners) for any transaction |
| What it shows | Planned sale size and broker | Actual execution date, price, and final shares |
| Trading signal | Forward‑looking – potential supply | Confirmation of actual buying/selling |
| Required for open market purchase? | No (only for sales of restricted/control securities) | Yes (all purchases and sales) |
Best practice: Monitor both. Form 144 warns you that a sale is coming; Form 4 tells you it happened and at what price.
Scenario: A venture capital firm holds 2 million restricted shares of a recently public tech company. The lock‑up expires on November 1.
On October 28, the firm files Form 144 indicating it intends to sell 1 million shares (1% of outstanding, equal to 2 weeks of average volume) through Goldman Sachs, beginning "on or about November 2."
Trader reaction:
Follow‑up: On November 5, Form 4 filings (or Form 4 equivalent for the fund) would show the actual sale prices.
Caution: Not all Form 144 filings lead to immediate sales. Some are filed "to have the ability" to sell. Always check the "proposed sale date" and follow up with Form 4.
