664 Part V: Index Options and Futures
cisable into the June futures at April expiration. Since the June futures contract will
still have some time premium in it in April, the strategist cannot plan his strategy with
respect to where the actual S&P 500 Index will be in April.
Example: The S&P 500 Stock Index (symbol SPX) is trading at 410.50. The follow­
ing prices exist:
Cash (SPX): 410.50
June futures: 415.00
Options
April 415 coll: 5.00
June 415 coll: 10.00
If one buys the June 415 call for 10.00, he knows that the SPX Index will have
to rise to 425.00 in order for his call purchase to break even at June expiration. Since
the SPX is currently at 410.50, a rise of 14.50 by the cash index itself will be neces­
sary for break-even at June expiration.
However, a similar analysis will not work for calculating the break-even price for
the April 415 call at April expiration. Since 5.00 points are being paid for the 415 call,
the break-even at April expiration is 420. But exactly what needs to be at 420? The
June future, since that is what the April calls are exercisable into.
Currently, the June futures are trading at a premium of 4.50 to the cash index
(415.00 - 410.50). However, by April expiration, the fair value of that premium will
have shrunk. Suppose that fair .value is projected to be 3.50 premium at April expi­
ration. Then the SPX would have to be at 416.50 in order for the June futures to be
fairly valued at 420.00 (416.50 + 3.50 = 420.00).
Consequently, the SPX cash index would have to rise 6 points, from 410.50 to
416.50, in order for the June futures to trade at 420 at April expiration. If this hap­
pened, the April 415 call purchase would break even at expiration.
Quote symbols for futures options have improved greatly over the years. Most
vendors use the convenient method of stating the striking price as a numeric num­
ber. The only "code" that is required is that of the expiration month. The codes for
futures and futures options expiration months are shown in Table 34-1. Thus, a
March (2002) soybean 600 call would use a symbol that is something like SH2C600,
where S is the symbol for soybeans, H is the symbol for March, 2 means 2002, C
stands for call option, and 600 is the striking price. This is a lot simpler and more flex­
ible than stock options. There is no need for assigning striking prices to letters of the
alphabet, as stocks do, to everyone's great consternation and confusion.
