Varies by product. Products vary with the market. The market price of raw materials is also a factor.
Good is debatable. Investment funds will not buy a stock if the price/earnings is over 70 [I think it is 70, not certain].
Earning > 15 billion per year is alright.
Aiming for 1T stock value with P/E < 70 would be a good set of targets.
If you are buying stock or bidding on a corporation 1T is heinous. Find a cheaper one.
