Finance - the market by what companies actually do
About 3,000 US-listed companies and 500 ETFs on one map, grouped by what they do - macro, sector, sub-sector,
niche - each branch with the totals of the companies beneath it, from their own SEC filings. Zoom in and a branch
splits into its parts; zoom out and they reassemble. The map needs JavaScript; these pages say the rest in words.
