请问此题选C不对吧？答案解释：A crude oil producer would be short futures to hedge the risk of future falling prices. For example, falling prices would decrease future sales and income. Crude oil futures are in backwardation, causing successive futures contracts to be sold at lower prices and causing roll yield to be negative。但roll return不是near-farther再除near么？那未来price下降，in backwardation会导致roll return为正才对。谢谢。
