问题如下:
A client, Bob Valentine, believes the prices of large-capitalization
stocks will rise slightly, and he wants to profit from this movement using a
bull spread strategy. Osborne recommends that Valentine use 1/100 Dow Jones
Industrial Average (DJX) options expiring in two months. The current price of
DJX is $91. Exhibit 2 provides current option information for two DJX call
options expiring in two months.
Exhibit 2 DJX Call Options
Expiring in Two Months
Valentine decides
to use 100 contracts per position. Each contract is equal to 100 shares.
At
expiration of the DJX call options, the maximum potential profit from the bull
spread strategy recommended for Valentine is closest to:
选项:
A.
$60,000
B.
$6,000
C.
$26,000
解释:
Correct Answer: C
C is correct. A
bull spread combines a long call at a lower exercise price (X1 = 88)
and a short call at a higher exercise price (X2 = 94). The cost of X1
is c1 = $4.40, and the benefit from X2 is c2 =
$1.00.
The maximum profit per contract = (X2
– X1 – c1 + c2) × 100 = ($94 – $88 – $4.40 +
$1.00) × 100 = 2.60 × 100 = $260
The maximum profit for 100 contracts is
$260 × 100 = $26,000.
B is incorrect
because it looks only at the terminal value of the option, not their initial
costs.
C is incorrect
because it ignores the option premium, i.e., ($94 – $88) × 100 = $6,000.
这道题为什么不用考虑current price的91块啊?从94-91才是涨的profits吧?
