									   Writing covered call options

                                                                                                                               equity options
A conservative investor will generally write covered call options only, i.e. options on securities he already owns
in his portfolio. Covered writing provides the investor with additional income from his investment portfolio,
which protects his securities, at least partially, from a decline in market price. Covered options writing provides
a reasonable rate of return while limiting possible risks. In many cases, a conservative options writer, having
sold a covered option, will do nothing more than wait for the option to be exercised or to expire.

To skew the risk/reward ratio in the investor’s favour by collecting premium income from the sale of call
options. This income reduces the volatility of a portfolio, and studies have shown that it actually increases the
yield on a portfolio in a neutral or bearish market.

An investor holds 100 shares of ABC common stock. The current price is $14.00 per share. Concerned about
stable-to-slightly weakening prices, he decides to write 1 ABC JUN 15 call option at a premium of $0.50.

The investor has protected his ABC shares against moderate declines in share price down to $13.50 (i.e. $14.00 –
$0.50) since losses on his stock position will be compensated by the option premium he has received.

Scenario 1: ABC’s stock price rises above $15.00.
If the price of ABC shares increases above $15.00, the investor will find his shares “called” by the investor who
bought the call. In this case, the call writer will realize a net effective selling price of $15.50 per share, the strike
price of $15.00 plus the $0.50 premium received. Of course, the investor will experience an “opportunity cost” if
the price of ABC shares rises above $15.50, since he will not be able to sell his ABC shares at the higher price,
having committed himself to deliver at $15.00.

                                                                                                                            S t ra te g y
Scenario 2: ABC’s stock price stays below $15.00.
If the share price is stable and remains below $15.00 (the call strike price), the investor will retain all of his call
premium income, thereby substantially increasing the yield on his investment over what it would have been
without the calls.

        Several points are worth noting:

        • The option writer accepts a limited profit and return on his investment. If he is assigned, his profit is limited to
          $1.50 per share (stock price appreciation of $1.00 per share up to option strike price plus premium of $0.50) and
          he foregoes all incremental profits arising from a price increase in ABC shares above $15.00, as illustrated by
          the horizontal portion of the “covered write” line.

        • The covered writer’s break-even point is substantially below the unhedged shareholder. The covered write and
          “shares only” strategies cross the horizontal break-even axis at, $13.50 and $14.00, respectively.

                                                                                                                                 S t ra te g y
        • The “covered write” strategy is superior to the “shares only” strategy at any ABC price below $15.50 per share
          because of the premium received.

        • This strategy can also be moderately bullish, depending on the strike price of the option sold. The investor can
          do a covered call write as an alternative to an open sell order at a limit price. He would choose in this case an
          out-of-the-money strike reflecting the price to which he thinks the stock will increase.

        Furthermore, note that the uncovered call writer is prepared to take greater risks than the conservative writer in
        the hope of making larger profits. The risks involved in the “naked” call writing strategy are the potentially
        unlimited losses if the price of the stock rises significantly, whereas the potential gains are limited to the
        premium received. A sudden increase in the stock price, following the announcement of some favourable
        information, for example, would result in substantial losses since the uncovered writer is obligated to sell the
        shares at the strike price. Since the writer does not own the shares, he has to buy them at market value, which
        is higher.
