Industry is as each company files it with the SEC.

Families group the sub-industries a filer can choose between, so Discount Stores covers every variant inside it rather than splitting into a page per variant with two companies on each. The order is by what actually trades, price times volume on the latest stored bar, rather than by market capitalisation: that figure is derived from a filer-supplied share count which is sometimes wrong by orders of magnitude, and a ranking built on it puts those errors at the top.
