利率是常数时,早拿到钱不还是能获得投资收益吗,不应该期货价格高于远期合约价格吗

嗨,从没放弃的小努力你好:
回复Elisa Liu,本题问的是future和forward price的对比,即期初价格的比较,暂不考虑保证金部分
这道题目问的是当利率是一个常数,期货和远期的价格大小是怎样的。利率是一个常数,说明利率大小和标的物的市场价格之间的相关系数为0,此时long position赚钱亏钱跟利率没有什么太大的关系,早拿到钱和晚拿到钱是没有什么差别的,所以此时两者的价格是相等的。当它们之间的相关系数为positive时,代表利率会随着标的物的市场价格的上涨而上涨,此时long position赚钱,如果提前拿到现金流,就可以再投资出去,因为利率上升的情况下再投资的机会更好,只有期货是可以提前拿到这个现金流的,所以此时期货的价格会高于远期的价格。反之,当它们之间的相关系数为negative时,代表利率会随着标的物的市场价格的上涨而下跌,此时long position赚钱,但是利率下跌再投资的机会不是很好,所以不希望提前拿到现金流,更希望晚拿到这笔钱,所以此时远期合约的价格会高于期货。

NO.PZ2016031201000028问题如下When interest rates are constant, futures prices are most likely:A.less thforwarprices.B.equto forwarprices.C.greater thforwarprices. B is correct.When interest rates are constant, forwar anfutures will likely have the same prices. The prifferentiwill vary with the volatility of interest rates.

If futures prices are positively correlatewith interest rates, futures contracts are more sirable to holrs of long positions thare forwar.

If futures prices are negatively correlatewith interest rates, futures contracts are less sirable to holrs of long positions thare forwar. The more sirable contrawill tento have the higher price. 中文解析这里比较的是futures和forwar哪种情况下价格会不一样, 它们的定价公式 其实是一样的,唯一不同的是futures是每日结算。思考的角度是比较再投资收益的高低,因为futures是每日盯市,每日都会有现金的流入和流出,如果提前拿到现金流,且利率上升,就说明再投资收益上升,此时投资者更希望用futures合约,所以futures就会比forwar。所以价格上升,long方有收益,即有现金流入,若利率下降,再投资收益下降,投资者就不想提前获得现金流,futures就比forwar宜;若利率保持不变,则forwarfutures二者价格相同。 可是就算买forwar拿到现金流也并没有什么额外收入啊,就算利率和价格负相关,拿出来不也比不拿好吗?

,在利率一致的情况下,期货是标准化合约接受程度和认可度更高,价格应当高于远期合约,不是吗?
利率连续为什么就影响期货价格?那对于远期合约呢?课上没有讲这个吧
