10K Intel is building free filing and company research pages first. These guides explain the core forms behind the live explorer so readers can understand annual reports, quarterly updates, current reports, 13F holdings, insider transactions, proxy statements, and S-1 registration filings before turning them into watchlist alerts.
Each guide links readers back into the filing explorer instead of trapping them in a generic glossary. The point is to make public SEC pages more useful before asking for signups.
A 10-K is the annual source document for a public company. Start with the business, risk factors, MD&A, and financial statements, then compare the current filing against prior annual reports before deciding what deserves monitoring.
A 10-Q is the quarterly update between annual 10-K filings. Use it to track unaudited financial statements, MD&A explanations, liquidity, cash flow, risk-factor changes, and whether the company is confirming or breaking the story from the last annual report.
An 8-K is a current report for material company events. The fastest way to read one is to identify the item number, open attached exhibits, and decide whether the event changes the company's operating, financial, or governance picture.
A 10-K is the annual deep dive, a 10-Q is the quarterly update, and an 8-K is a current-event filing. Use the 10-K for baseline context, 10-Qs for recent operating changes, and 8-Ks for material events between periodic reports.
A Schedule 13D is a source filing for beneficial owners who cross 5% of a voting equity class and may have active plans or control-related intent. Read it for who owns the stake, how the position was built, Item 4 plans, funding, agreements, amendments, and what company-level disclosures should be monitored next.
Schedule 13D and Schedule 13G both report large beneficial ownership, but they signal different levels of intent and detail. Use 13D for active or control-related ownership analysis, and 13G for shorter passive, qualified institutional, or exempt reporting patterns that still deserve monitoring.
A Schedule 13G is a shorter beneficial ownership filing often used by eligible passive investors, qualified institutional investors, or exempt holders. Read it to identify who owns a large stake, what percentage and voting power they report, whether the filing is new or amended, and whether ownership changes deserve monitoring without assuming activist intent.
A 13F filing reports certain long positions in securities on the SEC’s Section 13(f) list, not a manager’s full portfolio or current strategy. Use it to study portfolio exposure, new positions, exits, and concentration, while remembering the data is delayed and incomplete.
A Form 4 reports changes in insider ownership, usually shortly after a transaction. Use it to see who bought, sold, exercised options, received shares, or changed beneficial ownership, then connect the transaction back to company events, compensation plans, amendments, and prior insider behavior.
A DEF 14A proxy statement explains what shareholders are being asked to vote on and how the company is governed. Use it to evaluate directors, executive compensation, ownership, related-party transactions, auditor matters, and shareholder proposals.
An S-1 is a Securities Act registration statement used for IPOs and certain other securities offerings, including resale registrations. This guide focuses on IPO-style S-1 research: business model, revenue quality, risks, ownership, dilution, proceeds, and amendments.
The free surface should answer real SEC questions before monetizing alert delivery. Guide pages create non-SEC-copy content, then point readers to live filing examples, company pages, and the original EDGAR source links.
