  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.

How it compares

every company on the site

    The bar ranks every company on the site from the lowest on the left to the highest on the right, in three equal thirds; the small figures under it are the values where each third starts, and the black tick is the middle company. The orange dot is this company; the grey ticks are the other companies in its industry (hover or tap for names). A hatched block is companies tied at none.
