well if you sales are up your net should be up, but since TIF is experiencing higher prices of precious metals that will squeeze their margins. Also you need to look how they manage their expenses, if the increase in sales, increased their admninstrative costs by substential amount thats not a good thing.
Sales are growing does not excaly mean that they are doing well. you have to look at the product their are selling and how interpret how changes in the prices of the product will effect their sales.
