I don't see how you could go wrong buying $5000 worth every $5 barrel price drop. In a year or two you will (probably) come out beating the market as oil simply can't be replaced in a year and the countries that pump the oil will have to taper production in order to be profitable. All eyes on US Shale as it heads for bankruptcy.
