chevron, exxon, conoco phillips all pay decent dividends. Wal-Mart, Kraft, P&G and Coca Cola pay decent ones. Microsoft and Intel for tech. Healthcare...eh. Biogen Idec has had a good ride lately but they don't pay a dividend. Abbot Labs probably.
Stay out of oil unless it's bigoil paying dividends.
Why did you choose those three industries? Are those the ones you've done research on? Do you know the metrics analysts use to guage the success of these three industries?
(What I'm saying is don't piss away your money unless you know what you're doing. Buy some books first; invest later.)
