问题如下:
(2) Once the manager purchases CDS protection, the issuer’s CDS spread immediately falls to 1.60%. What is the investor’s approximate mark-to-market gain or loss for a contract notional of €10,000,000?
选项:
A.The manager realizes an approximate loss of €131,250.
The manager realizes an approximate gain of €131,250.
The manager realizes an approximate gain of €525,000.
解释:
A is correct. The CDS spread decline of 0.15% leads to a new CDS contract price of 94.75 per 100 face value = 1 – (EffSpreadDurCDS×ΔSpread) or (8.75×0.60%).
The protection buyer (short risk) position therefore realizes an approximate mark-to-market loss of 131,250=(94.75-93.4375)/100×10,000,000 because of the 0.15% decline in CDS spreads.
计算的话我是用 -Dx(yield change)xMV 计算出了A or B
因为manager是protection buyer
(Fixed coupon - CDS spread)越大,protection buyer要补支付差
所以这里CDS spread变小了 是一个loss
这样理解正确么
或者怎么样理解会更直观
谢谢
