58 Part II: Call Option Strategies
|

very similar when the prices differ by small amounts. This can be seen without the
|
||||
use of a table. If one pays a dime more for the stock, his investment increases by $10
|
||||
per 100 shares, or $50 total on a 500-share transaction. However, the fact that he has
|
||||
received an extra dime for the call means that the investment is reduced by $62.50.
|
||||
Thus, there is no effect on the net investment except for commissions. The commis
|
||||
sion on 500 shares at 43.10 may be slightly higher than the commission for 500 shares
|
||||
at 43. Similarly, the commission on 5 calls at 3.10 may be slightly higher than that on
|
||||
5 calls at 3. Even so, the increase in commissions would be so small that it would not
|
||||
affect the return by more than one-tenth of 1 %.
|
||||
To carry this concept to extremes may prove somewhat misleading. If one were
|
||||
to buy stock at 40½ and sell the call at ½, he would still be receiving 40 net, but sev
|
||||
eral aspects would have changed considerably. The return if exercised remains amaz
|
||||
ingly constant, but the return if unchanged and the percentage downside protection
|
||||
are reduced dramatically. If one were to buy stock at 48 and sell the call at 8 - again
|
||||
for 40 net - he would improve the return if unchanged and the percentage downside
|
||||
protection. In reality, when one places a "net" order with a brokerage firm, he nor
|
||||
mally gets an execution with prices quite close to the ones at the time the order was
|
||||
first entered. It would be a rare case, indeed, when either upside or downside
|
||||
extremes such as those mentioned here would occur in the same trading day.
|
||||
SELECTING A COVERED WRITING POSITION
|
||||
The preceding sections, in describing types of covered writes and how to compute
|
||||
returns and break-even points, have laid the groundwork for the ultimate decision
|
||||
that every covered writer must make: choosing which stock to buy and which option
|
||||
to write. This is not necessarily an easy task, because there are large numbers of
|
||||
stocks, striking prices, and expiration dates to choose from.
|
||||
Since the primary objective of covered writing for most investors is increased
|
||||
income through stock ownership, the return on investment is an important consider
|
||||
ation in determining which write to choose. However, the decision must not be made
|
||||
on the basis of return alone. More volatile stocks will offer higher returns, but they
|
||||
may also involve more risk because of their ability to fall in price quickly. Thus, the
|
||||
amount of downside protection is the other important objective of covered writing.
|
||||
Finally, the quality and technical or fundamental outlook of the underlying stock
|
||||
itself are of importance as well. The following section will help to quantify how these
|
||||
factors should be viewed by the covered writer.
