short头寸

NO.PZ202108100100000104 问题如下 The most appropriate response to Troubaur’s supervisor’s question regarng the TSI forwarcontrais: A.a crease in TSI’s share price, all else equal. B.increase in the risk-free rate, all else equ C.a crease in the market priof the forwarcontract, all else equal. B is correct. From the perspective of the long position, the forwarvalue is equto the present value of the fferenin forwarprices:Vt = PV[Ft – F0]whereFt = FV(St +C–CBt)All else equal, increase in the risk-free rate before contraexpiration woulcause the forwarprice, Ft, to increase. This increase in the forwarpriwoulcause the value of the TSI forwarcontract, from the perspective of the short, to crease. Therefore, increase in the risk-free rate woulleto a loss on the short position in the TSI forwarcontra中文解析首先需要明确现在是远期合约的short头寸，问的是下列那种情况会产生损失。Ashort 远期合约，希望将来标的资产下跌。因此当标的价格下降，其他条件不变的情况下，short头寸会有gain,而不是loss；B根据公式F= S0(1 + Rf) T可知，当Rf增加，forwar约价格上升，对于short forwar方来说会产生损失；选BC作为short forwar一方，当forwar格下跌时，会有gain，而不是loss，C不能选。 之前助教回答https://class.pzacamy.com/qa/157960有几个问题没有懂（1）就是我平常时可以能理解，但是一旦结合了这个图之后就理解不了，我们是Short Position所以用右边的图，计算Value的时候当FP下降，Short ForwarValue是减小的，那为啥就是赚钱了呀？（2）拿卖水的例子来看，我约定了一个价格卖水，水价下跌我赚钱，这个可以理解；但是ForwarPrice这里就没有理解，假如FP下降，为什么就是赚的呢？
