Which of the following combinations replicates a long derivative position?
选项:
A.A short derivative and a long asset
B.A long asset and a short risk- free bond
C.A short derivative and a short risk- free bond
解释:
B is correct. A long asset and a short risk- free asset (meaning to borrow at the risk- free rate) can be combined to produce a long derivative position.
A is incorrect because a short derivative and a long asset combine to produce a position equivalent to a long risk- free bond, not a long derivative.
C is incorrect because a short derivative and a short risk- free bond combine to produce a position equivalent to a short asset, not a long derivative.
这是什么意思啊?好懵啊做这部分的题
