My own practice in recent years has been to analyze trends and convert them into investments. So for instance, I have substantial positions in McDonalds, Altria, Philip-Morris, Exxon Mobile, Facebook, and Service Corp (none of which do I patronize). People be gorging, smoking, posting online, and dying. To invest in rampant financial ignorance, I looked into pawn shops and payday loans, but those are all privately held (e.g. super-lucrative, don't need outside capital). I'm looking into banks, Visa and MasterCard, and other facilitators of credit and payments, as possible growth areas.
