In June, Todd Puckett bought stock in SBC Communications for $30 per share. At that time, Puckett sold an equivalent number of call options on SBC with an exercise price of $35 for $2.75. In September, at expiration, the stock is trading at $26. What is Puckett’s profit per share from his covered call strategy? Puckett:
A)
gained $1.25.
B)
gained $4.00.
C)
lost $1.25.



Since the option is out-of-the-money at expiration (MAX (0, S − X)), the options are worthless. Also, the stock decreased in value from $30 per share to $26 per share, creating a $4 loss. The $4 loss is partially offset by the $2.75 premium Puckett received. Therefore, the loss per share from the covered call position is $1.25 = (–$4 + $2.75).

James Jackson currently owns stock in PNG, Inc., valued at $145 per share. Thinking that PNG is overbought and will decrease in price soon, Jackson writes a call option on PNG with an exercise price of $148 for a premium of $2.40. At expiration of the option, PNG stock is valued at $152 per share. What is the profit or loss from Jackson’s covered call strategy? Jackson:
A)
gained $9.40.
B)
lost $4.60.
C)
gained $5.40.



The option is in-the-money at expiration (MAX (0, S-X) and the PNG stock will be called away from Jackson at $148 per share, limiting Jackson’s gain from owning the stock to $3 ($148-145). However, Jackson also gains the $2.40 from writing the call option. Therefore, Jackson’s gain from the covered call strategy is $5.40 ($3.00+$2.40).

George Mote owns stock in IBM currently valued at $112 per share. Mote writes a call option on IBM with an exercise price of $120. The call option is sold for $1.80. At expiration, the price of IBM is $115. What is Mote’s profit (or loss) from his covered call strategy? Mote:
A)
gained $3.00.
B)
gained $4.80.
C)
lost $3.20.



Since the option is out-of-the-money at expiration (MAX (0, S - X)), the option is worthless. Also, the stock increased in value from $112 per share to $115 per share, creating a $3 gain. The $3 gain in the stock price is added to the $1.80 gain from writing the (unexercised) call option. Therefore, the total gain is $4.80 ($3 + $1.80).

In October, James Knight owned stock in Valerio, Inc., that was valued at $45 per share. At that time, Knight sold a call option on Valerio with an exercise price of $60 for $1.45. In December, at expiration, the stock is trading at $32. What is Knight’s profit (or loss) from his covered call strategy? Knight:
A)
gained $11.55.
B)
lost $11.55.
C)
gained $1.45.



Since the option is out-of-the-money at expiration (MAX (0, S-X)), the option is worthless. Also, the stock decreased in value from $45 per share to $32 per share, creating a $13 loss. The $13 loss is partially offset by the $1.45 premium Knight received. Therefore, the total loss from the covered call position is $11.55 (-$13+$1.45).

The potential profits from writing a covered call position on a stock are:
A)
limited to the premium plus stock appreciation up to the exercise price.
B)
limited to the premium.
C)
greater than the potential profits from owning the stock.


The covered call: stock plus a short call, or a short put. The term covered means that the stock covers the inherent obligation assumed in writing the call. Why would you write a covered call? You feel the stock’s price will not go up any time soon, and you want to increase your income by collecting some call option premiums. To add some insurance that the stock won’t get called away, the call writer can write out-of-the money calls. You should know that this strategy for enhancing one’s income is not without risk. The call writer is trading the stock’s upside potential for the call premium. The desirability of writing a covered call to enhance income depends upon the chance that the stock price will exceed the exercise price at which the trader writes the call.  The owner of a stock has the rights to all upside potential. The profits for a short call are limited to the premium.
For example, say that a stock owner writes a covered call at a stock price (S) of $50 and an exercise price (X) of $55 for a premium of $4. If at expiration, the price of the stock is more than $50 but less than $55, the buyer will not exercise, and the writer will "gain" the premium plus any stock appreciation between $50 and $55. If at expiration, the price of the stock is more than $55, the buyer will exercise and the writer's gain is limited to the premium.

The desirability of writing a covered call to enhance income depends upon the chance that the stock price will exceed the exercise price at which the trader writes the call.  This is similar reasoning to selling (or going short) a put. A put is in-the-money when the exercise price is above the stock price. Since the seller of a put prefers that the buyer just pay the premium and never exercise, the seller wants the price of the stock to remain above the exercise price.
