How do you check the finicial success of a certain product?

Question

Is there like a website?

Answer 1

You can check the web site for the company that manufactures the product.  If you go to the 'investors' section, there should be a great deal of information, like their annual reports and other details, that can help you make a determination.

Answer 2

If its a public company and a pretty large part of their business they probably give some indication of this with their quarterly conference calls and sec filings - go back and check a few of those.  If its a private company, or even a public company with tight lips, you are very limited as to what you can do.  Just stuff like try talking to suppliers and retailers but this is tough and they probably won't tell you much either.
