问题如下:
The no-arbitrage price of the option is closest to:
选项:
A.USD 2.00
B.USD 2.93
C.USD 5.22
D.USD 5.86
解释:
The risk neutral probability of an up move is 57.61% (calculated in the previous question).
Node B: (0.5761 × 0 + 0.4239 × 4) × exp(-0.12
× 3/12) = 1.65, which is greater than the intrinsic value of the option at this
node equal to max(0, 52 – 60) = 0, so the option should not be exercised early
at this node.
Node C: (0.5761 × 4 + 0.4239 × 20) × exp(-0.12
× 3/12) = 10.46, which is lower than the intrinsic value of the option at this
node equal to max(0, 52 – 40) = 12, so the option should be exercised early at
node C, and the value of the option at node C is 12.
Node A: (0.5761 × 1.65 + 0.4239 × 12) ×
exp(-0.12 × 3/12) = 5.86, which is greater than the intrinsic value of the
option at this node equal to max(0, 52 – 50) = 2, so the option should not be
exercised early at this node.
