From a review of Company SEC filings and the Google Finance website, I found 5 City of Detroit, Michigan Companies that had their common stock trading with stock market caps of above $10 mil in early July 2020.
The table below shows the Gold-Standard US GAAP Pretax Income (Loss) From Continuing Operations for the second quarters and first quarters and of both 2020 and 2019 for each of these 5 excellent City of Detroit, Michigan Companies.
