Gapter 2: Covered Call Writing 41
do with it as he pleases. That income can represent a substantial increase in the
income currently provided by the dividends on the underlying stock, or it can act to
offset part of the loss in case the stock declines.
For readers who prefer formulae, the profit potential and break-even point of a
covered write can be summarized as follows:
Maximum profit potential = Strike price Stock price + Call price
Downside break-even point = Stock price - Call price
QUANTIFICATION OF THE COVERED WRITE
Table 2-1 and Figure 2-1 depict the profit graph for the example involving the XYZ
covered write of the July 50 call. The table makes the assumption that the call is
bought back at parity. If the stock is called away, the same total profit of $500 results;
but the price involved on the stock sale is always 50, and the option profit is always
$300.
Several conclusions can be drawn. The break-even point is 45 (zero total prof­
it) with risk below 45; the maximum profit attainable is $500 if the position is held
until expiration; and the profit if the stock price is unchanged is $300, that is, the cov­
ered writer makes $300 even if his stock goes absolutely nowhere.
The profit graph for a covered write always has the shape shown in Figure 2-1.
Note that the maximum profit always occurs at all stock prices equal to or greater
than the striking price, if the position is held until expiration. However, there is
downside risk. If the stock declines in price by too great an amount, the option pre­
mium cannot possibly compensate for the entire loss. Downside protective strategies,
which are discussed later, attempt to deal with the limitation of this downside risk.
