From a review of Company SEC filings and the Google Finance website, I found 34 Milwaukee Area Headquartered Companies with stock market caps of above $1 mil in mid-July 2020. Twenty of them were headquartered in the City of Milwaukee and 14 in the Milwaukee suburbs.
The table below shows the Gold-Standard US GAAP Pretax Income (Loss) From Continuing Operations for the second and first quarters of both 2020 and 2019 for each of these 34 excellent Milwaukee Area Companies.
