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 and . 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:
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?
