SEC filings for traders (S-1, 424B, 8-K)
SEC filings are the documents public companies must file with the Securities and Exchange Commission on its EDGAR system. For a small-cap trader a handful matter most: the S-1 and S-3 that register stock for sale, the 424B prospectuses that price it, and the 8-K that reports news within four business days.
Why it matters to a small-cap momentum trader
Headlines tell you a stock is moving. The filing tells you what the company has committed to: how many shares, at what price, with how many warrants, and whether insiders are selling. Small caps raise money often, and the paperwork for a raise usually reaches EDGAR before or with the press release. A trader who can find the right page in a prospectus in a minute knows where the supply is.
The filings that matter most
| Form | What it is | What it can mean for the price |
|---|---|---|
| S-1 | A full registration of shares for sale, or for resale by investors | An offering or a resale is being prepared |
| S-3 | A short-form registration, often a shelf for sales later | The company can sell quickly once it is effective |
| EFFECT | The SEC's notice that a registration is effective | The registered shares can now be sold |
| 424B4 | The final prospectus of a priced offering | The price and size of the deal |
| 424B5 | A prospectus supplement for a sale off a shelf | A registered direct, an ATM or a takedown |
| 8-K | A current report of a material event | News: deals, results, delisting notices, sales of stock |
| Form 4 | An insider's trade, due within two business days | Insiders buying or selling |
| NT 10-K, NT 10-Q | Notice that a periodic report will be late | Often a sign of trouble at a small company |
The 8-K items to know
- Item 1.01: a material agreement, such as a deal, a license or a financing.
- Item 2.02: results of operations, the earnings release.
- Item 3.01: a delisting notice or a failure to meet a listing rule, such as the minimum bid.
- Item 3.02: unregistered sales of stock, such as a private placement.
- Item 5.07: the results of a shareholder vote, for a reverse split or more authorized shares.
- Items 7.01 and 8.01: other news the company chooses to report, often with the press release attached.
SEC filings in Hindsight Markets
The Filings window shows every filing the SEC had accepted by that moment in the replay, grouped by tab, and a filing that lands while you watch is marked new. One from later in the day will not open. Each filing opens on its own page, as the company filed it, with its exhibits, an outline and a search box.
A worked example: reading a 424B5 in a minute
An illustration with made-up numbers, not a real company or a real filing.
The cover. 2,000,000 shares and warrants to buy 2,000,000 shares, at a combined price of 1.25. The warrants are exercisable at 1.40 for five years.
The size. 2,000,000 × 1.25 = 2.5 million dollars before fees.
The share count. The "Offering" summary says shares outstanding before the offering are 8,000,000 and after it 10,000,000, a 2,000,000 ÷ 8,000,000 = 25% increase, before any warrant is exercised.
What a trader takes from it. New supply bought at 1.25, and another 2 million shares that become saleable above 1.40.
Common mistakes small-cap traders make with SEC filings
- Reading the press release and not the filing. The release leads with the good part. The prospectus has the share count, the warrants and the fees.
- Treating every 8-K as news. Many are routine. Read the item number first: a 1.01 or a 3.01 says more than an exhibit update.
- Missing a filing from the evening before. Filings accepted after the close set up the next morning's gap. Check them before the pre-market.
- Confusing a registration with a sale. An S-1 or S-3 makes a sale possible. A 424B with a price is the sale.
Common questions
- What is an S-1 filing?
- The full registration statement a company files to register shares for sale to the public, for an IPO, a follow-on offering, or the resale of shares investors bought privately. The shares cannot be sold under it until the SEC declares it effective.
- What is a 424B5?
- A prospectus supplement filed for a sale off an effective shelf registration. On a small cap it usually means a registered direct offering, an at-the-market program or another takedown of new shares.
- What is the difference between a 424B4 and a 424B5?
- A 424B4 is the final prospectus of an offering that went through a full registration, such as an IPO or an S-1 deal. A 424B5 supplements a shelf prospectus that is already effective.
- What is the deadline for an 8-K?
- Generally four business days after the event. Many small caps file it the same day as the press release, sometimes before the open.
- What triggers an 8-K filing?
- Events the SEC lists by item: material agreements, earnings results, delisting notices, unregistered stock sales, changes in officers, shareholder votes and other news the company chooses to report.
