Guide · The earnings graph
Sectors and the ring
Companies are grouped by GICS sector, and the sectors sit around a ring in alphabetical order, each a hub with its companies around it. A sector keeps its colour and its place whatever else changes.
Sectors
Every company in the run is classified under the Global Industry Classification Standard (GICS), which sorts listed companies into 11 sectors, then into finer industry groups, industries and sub-industries. The graph groups companies by sector. A company with no classification goes in a group of its own, Unclassified. See SIC and GICS for how the two classification systems on this page differ.
The ring
Each sector is drawn as a hub, the large dot, with its companies around it, the biggest companies (by how much the run extracted about them) nearest the centre. The sectors sit around a ring in alphabetical order, the same order as the row of sector names at the top of the graph.
Alphabetical order is deliberate. A sector keeps its place on the ring when companies are added or sectors grow, so a sector is where you last saw it.
Colours
Each sector has a fixed colour, on its hub and its companies, so it keeps its colour from one run to the next. Sector colours never use amber, which the page keeps for supplier dependencies. Colour is not the only cue: every sector is named, and its companies sit together.
Selecting a sector
Click a hub, or a name in the row at the top, to select a sector. Its companies are listed in the panel, and its supplier links to other sectors stay drawn however far you zoom in. See sector roll-ups.
