问一道题:NO.PZ2016070201000031 [ FRM II ]

问题如下:

Suppose an individual buys a correlation swap with a fixed correlation of 0.2 and a notional value of $1 million for one year. The realized pairwise correlations of the daily log returns at maturity for three assets are ρ2,1=0.7,ρ3,1=0.2\rho_{2,1}=0.7,\rho_{3,1}=0.2 and ρ3,2=0.3\rho_{3,2}=0.3. what is the correlation swap buyer’s payoff at maturity?

选项:

A.

$100,000.

B.

$200,000.

C.

$300,000.

D.

$400,000.

解释:

Calculate the realized correlation as follows:

ρrealized=2323×(0.7+0.2+0.3)=0.4\rho_{realized}=\frac2{3^2-3}\times{(0.7+0.2+0.3)}=0.4

The payoff for the correlation buyer is then calculated as:

$1,000,000*(0.4-0.2)=$200,000

这里的pay-off的意思是buyer盈利的部分吗?为什么这个swap的pay-off是correlation之差乘以notion-value?这乘出来的东西是个什么经济含义?

同学你好,这里的pay-off的意思是buyer的盈亏。因为本题是一个correlation swap,该swap的买方,当realied correlation大于fixed correlation时,可以盈利赚钱,相关知识点在讲义的103-104页
