I am trying to find liquidity ratios, profability ratios, and solvency ratios for different companies for the years 2003, 2004, 2005, and 2006. Does anyone know of a website that I can go to to get that kind of informaton?

For Canadian companies, go to Welcome to the SEDAR Web Site / Bienvenue au Site Web SEDAR

For American companies, go to SEC Filings & Forms (EDGAR)

Those websites provide all the financial statements, so from there, you can calculate the ratios.

Also, some companies put their financial information on their personal website.
