From a review of companiesmarketcap.com, of valuetoday.com, of the Google Finance website and of Company SEC filings, there were 126 California Companies with stock markets caps above $10 Bil sometime during the month of August 2022. I only included in these 126 California Companies ones where the Company was headquartered in California for a large portion of the 13 years from 2008 to 2021.
From Company financial statements contained in the SEC website, the table below shows the Audited Gold-Standard US GAAP Consolidated Net Income (Loss) from Continuing Operations for each of these 126 largest California Companies for 2021, the Biden Administration's first year in office, for 2020, the Trump Administration's last year in office, for 2016, the Obama Administration's last year in office and for 2008, the Bush Administration's last year in office.
There are a small handful of these 126 Companies that had very significant company separations which made their reported 2008 earnings amounts not meaningful in comparison to their more recent years' earnings amounts and thus their reported 2008 earnings are excluded from the below table.
