For US stocks, you can usually get their released annual and quarterly reports from the Investor Relations section of their websites. For instance, Facebook Investor Relations, Apple Investor Relations, Microsoft Investor Relations, Alphabet Investor Relations, Amazon Investor Relations etc. It is easy to find them, just search Google with search terms like "facebook investor relations", "amazon investor relations", etc. Explore the IR section and you will be able to find their financial statements.
ShortcutsFor quick reference to stocks and financial statistics of companies listed on Bursa Malaysia, I use "KLSE Screener". It is a little mobile phone app providing concise but surprisingly rich financial information of listed companies.
You can get the financial data of US's listed companies at various financial websites. I like Google Finance's "Financials" section of a stock's page, i.e. Facebook's Financials, Amazon Financials, etc.
For statistics, news, and market consensus, Yahoo Finance is the best place to go. For instance, Yahoo Finance page for Facebook, Yahoo Finance page for Microsoft, etc.
