New to this? How to read this page
  1. Companies file with the SEC when something happens. 10-Q and 10-K are the quarterly and annual reports; 8-K is news that cannot wait for the next report.
  2. An 8-K says which items it covers, such as results, a change at the top or a big contract. A foreign company files a 6-K instead.
  3. The results release is usually an 8-K filed the day results come out, before the 10-Q or 10-K.
  4. Every filing links to the original on EDGAR, the SEC's own site.
