ANSWER: C
There is mainly basis risk for positions that are both long and short either different months or contracts. Position II. is long twice the same contract and thus has no basis risk (but a lot of directional risk) .
讲义上写basis is the difference between the spot price of an asset and its futures price. 请问basis risk是否不仅存在于现货和期货之间,期货跟期货之间也存在basis risk?
