The Electronic Data Gathering, Analysis, and Retrieval system (EDGAR) is the SEC's public database of all corporate filings submitted by public companies operating in the United States. Every S-3, 10-K, 10-Q, 8-K, and hundreds of other filing types are publicly available through EDGAR within minutes of submission.
For traders focused on dilution risk, EDGAR is the primary source of truth. Every piece of material dilution information — new share registrations, ATM programs, PIPE deals, warrant issuances — must be disclosed through EDGAR filings. If you can monitor EDGAR effectively, you have access to the same primary data as institutional investors.
All EDGAR data is freely available to anyone with internet access. You don't need a Bloomberg terminal or expensive data service to access the raw filings. The challenge is volume and velocity — thousands of filings hit EDGAR every day, and manually processing them is impractical.
EDGAR's full-text search system (efts.sec.gov) allows you to search the content of filings, not just filing metadata. This is powerful for dilution research. Here's how to use it effectively:
Navigate to efts.sec.gov/LATEST/search-index?q="at-the-market"&forms=424B3 to find all recent 424B3 filings mentioning "at-the-market." Adjust the query and form type to narrow results.
"at-the-market" forms=424B3 — Find new ATM program filings"going concern" forms=10-K,10-Q — Find companies with going concern opinions"private placement" forms=8-K — Find PIPE deals"shelf registration" forms=S-3 — Find new shelf registrations"convertible note" forms=8-K — Find convertible debt issuances"H.C. Wainwright" forms=424B3 — Find all ATM deals managed by this brokerUse &dateRange=custom&startdt=2026-01-01&enddt=2026-03-31 to filter results to a specific time period. This is useful for finding all dilution activity in a specific quarter for a company or sector.
Add &entity=[ticker] to your search to filter results to a specific company. For example, searching "at-the-market"&forms=424B3&entity=XYZ finds all ATM filings from ticker XYZ.
EDGAR provides a free email alert system that notifies you when a specific company files new documents. While basic, it's a useful free tool for monitoring a small watchlist:
sec.gov/cgi-bin/browse-edgar?action=getcompanyEDGAR alert emails typically arrive 15-60 minutes after filing submission. They include a link to the filing but no context or analysis.
EDGAR email alerts have several problems for active traders: (1) There's no mobile push notification — email only. (2) They provide no analysis or context. (3) The delay can be 30-60 minutes. (4) You can only monitor individual companies, not filing-type patterns across your watchlist.
Not all SEC filings are equally relevant for dilution risk. Focus your EDGAR monitoring on these high-priority types:
The foundational document for most secondary dilution. An S-3 registration means a company has established the legal framework to issue new shares. Track when S-3s are filed, declared effective (usually 20 days after filing unless reviewed), and used.
These are the operational documents for ATM offerings. A 424B3 is typically the ATM program establishment document. A 424B5 is often a supplement updating or expanding an existing program. Both signal active or imminent dilution.
Covers PIPE deals, securities purchase agreements, and other private placements. When a company signs a financing agreement, this 8-K is filed within 4 business days. This is often the first public disclosure of a PIPE transaction.
Specifically covers private placements where shares are sold without SEC registration. Every PIPE deal, every private warrant issuance, and most convertible note transactions will appear here. This is one of the most important filing types for dilution monitoring.
While primarily for IPOs, S-1 filings also appear when a company is doing a very large registered offering or has never previously registered with the SEC. An S-1 amendment (S-1/A) can update terms of an offering in progress.
Morning routine: Check last 24h of 424B3 and 8-K 3.02 filings for your watchlist.
Intraday: Watch for S-3 effectiveness notices and 8-K 1.01 filings.
Weekly: Review 10-Q and 10-K filings for cash runway updates and warrant table changes.
Quarterly: Full dilution review — shares outstanding changes, new warrant grants, shelf capacity consumed.
The SEC provides a free, public API for accessing EDGAR data programmatically. For technically inclined traders, this unlocks powerful monitoring capabilities:
Access a company's financial data in structured JSON format: data.sec.gov/api/xbrl/companyfacts/CIK[number].json. This includes shares outstanding, cash balances, and other XBRL-tagged financial data that can be used to calculate cash runway and dilution metrics.
Get a company's complete filing history: data.sec.gov/submissions/CIK[number].json. Returns all filings with dates, form types, and links to documents. Useful for building a timeline of a company's dilution history.
The EDGAR full-text search is also available as an API: efts.sec.gov/LATEST/search-index?q=[query]&forms=[type]. Returns structured results that can be processed programmatically.
Rate limits apply: the SEC asks for a maximum of 10 requests per second from any single IP, with a User-Agent header identifying your application and contact email.
Despite its value, EDGAR has significant limitations for traders who need to stay ahead of dilution events:
DilutionWatch was built specifically to solve the gap between EDGAR's public data and actionable dilution intelligence. The platform processes every relevant filing from EDGAR in real-time, extracts the key data points (shelf capacity, offering size, broker identity, warrant terms), calculates dilution metrics, and delivers alerts with full context directly to traders.
Instead of spending 2 hours per day manually checking EDGAR and reading filings, DilutionWatch reduces that to minutes — you get an alert, see the pre-calculated dilution impact, and can make an informed decision immediately.
Stop manually checking EDGAR. DilutionWatch processes every relevant filing in real-time and delivers instant, contextualized dilution alerts for your entire watchlist.
