Re Robert Peston, it isn't at all clear whether the Royal Mail are using futures to buy equities at a price they want to pay, or whether they are gambling on the price going up or down. It's the same with commodities trading - people who are producing commodities and the end users use futures to give themselves some certainty. It's the middle men who are the gamblers.
