这段话解释一下,at timeT,the short sale is covered at ST,and under the no-arbitrage condition of F(T)=S(1+R),the return is equal to f(T)-s(T) for both the short forward and the replication strategy.

ヾ(◍°∇°◍)ノ゙你好同学,
at time t=T,the short sale is covered at ST,and under the no-arbitrage condition of F(T)=S(1+R)
在到期T时刻,short sale将会以ST价格买到的现货归还股票,在无套利情况下,F0(T)=S0x(1+R)^T
之所以T时刻换股票,是因为期初借入了股票,在市场上卖出short sale,于是期末需要从市场上买回来股票,然后还给一开始的出借方
the return is equal to f(T)-s(T) for both the short forward and the replication strategy.
对于远期合约的short方,或者复制策略,在T时刻期末的收益是F0(T)-ST
