which top industries of the world ?

I own stock in ICICI bank (IBN). It's done pretty well for me. Your subject is "top industries of the world" and your body says "top industries of India." I don't know the current stats on top industries of India. In the world, I would have to say banking. Everything stops and starts with banking. You can say that about all industries though; oil, energy, Wal-mart..: )
