6. The most appropriate response to Troubadour’s supervisor’s question regarding the TSI forward contract is:
选项：
A.a decrease in TSI’s share price, all else equal.
B.an increase in the risk-free rate, all else equal
C.a decrease in the market price of the forward contract, all else equal.
解释：
B is correct.
From the perspective of the long position, the forward value is equal to the present value of the difference in forward prices:
Vt(T)= PVt,T[Ft(T)-F0(T)]
where Ft(T) =FVt,T(St+θt-γt)
All else equal, an increase in the risk-free rate before contract expiration would cause the forward price, Ft(T), to increase. This increase in the forward price would cause the value of the TSI forward contract, from the perspective of the short, to decrease. Therefore, an increase in the risk-free rate would lead to a loss on the short position in the TSI forward contract.
老师我不懂这句话：All else equal, an increase in the risk-free rate before contract expiration would cause the forward price, Ft(T), to increase.利率上升怎么会使得forward price也上升呢？
