I watched one of those 'get rich quick' videos of a seminar. The guy talks convincingly about 'renting out' your blue chip shares. Anyone got any idea what the proper name for this is? i.e futures, warrants, options? He talked so vaguely about this concept that he didn't even say what it was called. But he gave the impression that once you had 50000 bucks to invest, you could replace your income.
