224 Part II: Call Option Strategies

before April expiration. He should then figure his collateral requirement as if the
|
||||
stock were at 53, regardless of what the collateral requirement is at the current time.
|
||||
This is a prudent tactic whenever naked options are involved, since the strategist will
|
||||
never be forced into an unwanted close-out before his defensive action point is
|
||||
reached. The collateral required for this example would then be as follows, assuming
|
||||
the call is trading at 3½:
|
||||
20% of 53
|
||||
Call premium
|
||||
Less initial credit
|
||||
Total collateral to set aside

The strategist is not really "investing" anything in this strategy, because his require
|
||||
ment is in the form of collateral, not cash. That is, his current portfolio assets need
|
||||
not be disturbed to set up this spread, although losses would, of course, create deb
|
||||
its in the account. Many naked option strategies are similar in this respect, and the
|
||||
strategist may earn additional money from the collateral value of his portfolio with
|
||||
out disturbing the portfolio itself. However, he should take care to operate such
|
||||
strategies in a conservative manner, since any income earned is "free," but losses may
|
||||
force him to disturb his portfolio. In light of this fact, it is always difficult to compute
|
||||
returns on investment in a strategy that requires only collateral to operate. One can,
|
||||
of course, compute the return on the maximum collateral required during the life of
|
||||
the position. The large investor participating in such a strategy should be satisfied
|
||||
with any sort of positive return.
|
||||
Returning to the example above, the strategist would make his $50 credit, less
|
||||
commissions, if the underlying stock remained below 50 until July expiration. It is not
|
||||
possible to determine the results to the upside so definitively. If the April 50 calls
|
||||
expire worthless and then the stock rallies, the potential profits are limited only by
|
||||
time. The case in which the stock rallies before April expiration is of the most con
|
||||
cern. If the stock rallies immediately, the spread will undoubtedly show a loss. If the
|
||||
stock rallies to 50 more slowly, but still before April expiration, it is possible that the
|
||||
spread will not have changed much. Using the same example, suppose that XYZ ral
|
||||
lies to 50 with only a few weeks of life remaining in the April 50 calls. Then the April
|
||||
50 calls might be selling at l ½ while the July 50 call might be selling at 3. The ratio
|
||||
spread could be closed for even money at that point; the cost of buying back the 2
|
||||
April 50's would equal the credit received from selling the one July 50. He would thus
|
||||
make½ point, less commissions, on the entire spread transaction. Finally, at the expi
|
||||
ration date of the April 50 calls, one can estimate where he would break even.
|
||||
Suppose one estimated that the July 50 call would be selling for 5½ points if XYZ
|
||||
were at 53 at April expiration. Since the April 50 calls would be selling for 3 at that
