我同意lz的观点。我觉得Delta Hedge的本意是用underlying asset来hedge期权:
Delta Hedging: An options strategy that aims to reduce (hedge) the risk associated with price movements in the underlying asset by offsetting long and short positions. For example, a long call position may be delta hedged by shorting the underlying stock.
这里用Short call来Hedge持有的黄金应该是没用的。不过对这道题,是否Delta Hedge并不影响后面答案。
从概念上看,Short Call在金价下跌超过Premium时是亏的,所以这个组合在金价大幅下跌时肯定是亏损的。
过了一周后,Call option的FMV减少,Long方Loss,Short方Gain(因为Market value的Hedge是按市值入账的,unrealized gain/loss是要计入Income statement的)。
如果金价涨到1005,把持有的黄金的Gain和Short call positionl的Loss加起来就是答案了(忽略Option的Premium,好像题里没给)。数字我忘掉了。 |
