What is a good place or website to find current information about companies, commodities and business?

Ive started doing a bit of investing and was wondering where i could find some detailed information about companies and commodities(but mostly companies). I currently trade with TD Ameritrade so information regarding the quarterly profits of companies are available to me, as well as recommendations made by anaylsts such as S&P.

However, I cant find market share information on TD ameritrade, as well as value breakdowns of companies. As in this type of product makes up x % of this companies value, and they have an x% market share in that area.
