retical cash value. He is not too eager to sell at such a discount, but he realizes tha
|
||||
he has a lot of exposure between the current price and the guarantee price of 10.
|
||||
He might consider writing a listed call against his position. That would conver
|
||||
it into the equivalent of a bull spread, since he already holds the equivalent of a lonf
|
||||
call via ownership of the structured product. Suppose that he quotes the $SP)
|
||||
options that trade on the CBOE and finds the following prices for 6-month options
|
||||
expiring in December:
|
||||
$SPX: 1,200

|

Suppose that he likes the sale of the December 1,250 call for 62 points. How
|
||||
many should he sell against his position in order to have a proper hedge?
|
||||
First, one must compute a multiplier that indicates how many shares of the
|
||||
structured product are equivalent to one "share" of the $SPX. That is done in the
|
||||
simple case by dividing the striking price by the guarantee price:
|
||||
Multiplier = Striking price/ Base price
|
||||
= 700 / 10 = 70
|
||||
This means that buying 70 shares of the structured product is equivalent to
|
||||
being long one share of $SPX. To verify this, suppose that one had bought 70 shares
|
||||
of the structured product initially at a price of 10, when $SPX was at 700. Later,
|
||||
assume that $SPX doubles to 1,400. With the simple structure of this product, which
|
||||
has a 100% participation rate and no adjustment factor, it should also double to 20.
|
||||
So 70 shares bought at 10 and sold at 20 would produce a profit of $700. As for $SPX,
|
||||
one "share" bought at 700 and later sold at 1,400 would also yield a profit of $700.
|
||||
This verifies that the 70-to-l ratio is the correct multiplier.
|
||||
This multiplier can then be used to figure out the current equivalent structured
|
||||
product position in terms of $SPX. Recall that the investor had bought 15,000 shares
|
||||
initially. Since the multiplier is 70-to-l, these 15,000 shares are equivalent to:
|
||||
$SPX equivalent shares = Shares of structured product held/ Multiplier
|
||||
= 15,000 / 70 = 214.29
|
||||
That is, owning this structured product is the equivalent of owning 214+ shares
|
||||
of $SPX at current prices. Since an $SPX call option is an option on 100 "shares" of
|
||||
$SPX, one would write 2 calls (rounding off) against his structured profit position.
|
||||
Since the SPX December 1,250 calls are selling for 62, that would bring in $12,400
|
||||
less commissions.
