I analyzed 326 profitable companies from the S&P 500 Index. I discovered that their total revenues is ~$12.2T, and the total net income is $535B, which amounts to a 4.4% net profit margins.

By far, the biggest expenses for a corporation are: COGS, SGA/R&D/ Marketing, Interest Expense, DEPRECIATION/AMORTIZATION, Tax.

I'd like to do the same sort of analysis with non-profitable corporations as well. Their tax rate is 0%. I'd like to analyze why are they unprofitable (high interest payments? Depreciation/ Amortization? High COGS? etc.).
