I think that the classification of Insurance came from WMIH whose name was later changed to COOP.
At TDA, which probably gets the info from NASDAQ, COOP is in the "Financial" sector and "Thrifts & Mortgage Finance" industry. Although it is better to fix IHUB. what is important is the categorization at NASDAQ which will compare COOP to other companies in the Finance sector and they are doing very well during this economic turmoil. Finance is one of the few sectors that still shine while tech for instance is in the dumpster.
