Note that each of the four tactics proves to be the best tactic in one case or another,
but that the spread tactic is never the worst one. Tables 3-2 and 3-3 represent the
results from holding until expiration. For those who prefer to see the actual numbers
involved in making these comparisons between the four tactics, Table 3-3 summa­
rizes the potential profits and losses of each of the four tactics using the prices from
the example above. 'W" indicates that the tactic is the worst one at that price, and
"B" indicates that it is the best one.
There are, of course, modifications that an investor might make to any of these
tactics. For example, he might decide to sell out half of his long call position, recov­
ering a major part of his original cost, and continue to hold the remainder of the long
calls. This still leaves room for further appreciation.
