SEC Filings Filter

Selecting SEC Fillings from the type filter narrows the right feed to raw SEC documents only and replaces the left panel with a grouped list of every filing type — so you can drill into exactly the kind of filing you want to track.

Selecting SEC Fillings

Click the type filter button (top-right) and select SEC Fillings. Two things happen:

Right feed — shows only raw SEC filing rows. Each row shows the form name and items (e.g. Form 424B2 - Prospectus [Rule 424(b)(2)], Form 8-K - Current report). No news rows, no impact bars.
Insighthread's right feed with SEC Fillings selected — rows show form name, ticker, and filing period; no news rows or impact bars
Left panel — the sector list is replaced by a grouped filing type list with every form code Insighthread covers.
Insighthread's left panel with SEC Fillings active — sector list replaced by grouped filing types list

Left Panel — Filing Type List

Filing types are grouped by category. Each row shows the filing name and its form code on the right (e.g. 10-Q, 8-K, ARS). The same include/exclude filtering applies as the News Filter — first click includes, second click excludes, third click resets.

How Filing Type Filtering Works

Same three-state toggle as the News Filter:

Click	State	Effect
First	Include ✓	Feed shows only filings of that type
Second	Exclude −	Filings of that type are hidden
Third	Reset	No filter for that type

You can include or exclude multiple types simultaneously.

Opening a Filing

Click any row in the SEC Filings feed to open the Document Viewer.

Insighthread Document Viewer — Insighthread's Document Viewer — form type, ticker, and filing period header with zoom controls and page navigation

The viewer renders the raw filed document directly from SEC EDGAR:

Header — form type, ticker, and filing period (e.g. SCHEDULE 13G · AAP · Q3 2026)
Zoom controls — 100% default with − and + to zoom in/out
Page navigation — up/down arrows to move between pages
Document tab — confirms the form type being viewed
Full document — the actual filed text exactly as submitted to the SEC, including all exhibits

Insighthread filed document viewer — Full filed document as submitted to the SEC, rendered in Insighthread — complete text with all exhibits

You can open AI Chat from the Document Viewer to ask questions about any filing. The AI automatically has the document as context — no need to paste or describe it.
