Frequently asked questions
Which filings get a brief?
Form 8-K filings by companies listed on a US stock exchange (NYSE, Nasdaq, Cboe; not over-the-counter stocks) that report a material event: results (Item 2.02), deals (1.01, 2.01), executive changes (5.02), restructuring (2.05), impairments (2.06), delisting notices (3.01), restatements (4.02), cybersecurity incidents (1.05), bankruptcy (1.03) and Regulation FD or other events (7.01, 8.01). Routine filings such as vote results or exhibits only are skipped.
How is the impact score set?
The AI rates each filing from 1 (routine) to 5 (major, such as a merger, bankruptcy or restatement) based only on what the filing says. It is a reading aid for sorting the day's filings, not a prediction of how the stock will move.
How quickly do briefs appear?
On weekdays the SEC filing feed is checked every 5 minutes from 6 am to 5:45 pm Eastern, when nearly all 8-Ks come in, and every hour after that until 10 pm. Briefs of the 1,000 largest companies follow within minutes; the others usually within the hour, or later the same day when many filings arrive at once.
Which companies are covered?
Every company with shares listed on the NYSE, Nasdaq or Cboe that files 8-Ks, about 4,500 of them. Foreign companies that report on Form 6-K instead are not included. The S&P 1500 only filter above narrows the list to the large, mid and small caps of the S&P Composite 1500.
Are older briefs kept?
Yes. This page shows the last 45 days, but every brief ever published stays online: each has its own page, and each company has an 8-K page listing all of its briefs, newest first, linked from its stock page and from the A-Z list of companies.
