TYPES OF OPTIONS – CALLS AND PUTS

Call Option Definition:
A call option is an option contract in which the holder (buyer) has the right (but not the obligation) to buy a specified quantity of a security at a specified price (strike price) within a fixed period of time (until its expiration).

For the writer (seller) of a call option, it represents an obligation to sell the underlying security at the strike price if the option is exercised. The call option writer is paid a premium for taking on the risk associated with the obligation.

For stock options, each contract covers 100 shares.

Buying Call Options

Call buying is the simplest way of trading call options. Novice traders often start off trading options by buying calls, not only because of its simplicity but also due to the large ROI generated from successful trades.

 

A Simplified Example

Suppose the stock of XYZ company is trading at $40. A call option contract with a strike price of $40 expiring in a month's time is being priced at $2. You strongly believe that XYZ stock will rise sharply in the coming weeks after their earnings report. So, you paid $200 to purchase a single $40 XYZ call option covering 100 shares.

Say you were spot on and the price of XYZ stock rallies to $50 after the company reported strong earnings and raised its earnings guidance for the next quarter. With this sharp rise in the underlying stock price, your call buying strategy will net you a profit of $800.

Let us take a look at how we obtain this figure.

If you were to exercise your call option after the earnings report, you invoke your right to buy 100 shares of XYZ stock at $40 each and can sell them immediately in the open market for $50 a share. This gives you a profit of $10 per share. As each call option contract covers 100 shares, the total amount you will receive from the exercise is $1000.

Since you had paid $200 to purchase the call option, your net profit for the entire trade is $800. It is also interesting to note that in this scenario, the call buying strategy's ROI of 400% is very much higher than the 25% ROI achieved if you were to purchase the stock itself.

This strategy of trading call options is known as the long call strategy.

Selling Call Options

Instead of purchasing call options, one can also sell (write) them for a profit. Call option writers, also known as sellers, sell call options with the hope that they expire worthless so that they can pocket the premiums. Selling calls, or short call, involves more risk but can also be very profitable when done properly. One can sell covered calls or naked (uncovered) calls.

Covered Calls

The short call is covered if the call option writer owns the obligated quantity of the underlying security. The covered call is a popular option strategy that enables the stockowner to generate additional income from their stock holdings thru periodic selling of call options.

Naked (Uncovered) Calls

When the option trader writes calls without owning the obligated holding of the underlying security, he is shorting the calls naked. Naked short selling of calls is a highly risky option strategy and is not recommended for the novice trader.

Call Spreads

call spread is an options strategy in which equal number of call option contracts are bought and sold simultaneously on the same underlying security but with different strike prices and/or expiration dates. Call spreads limit the option trader's maximum loss at the expense of capping his potential profit at the same time.

Put Option Definition:
A put option is an option contract in which the holder (buyer) has the right (but not the obligation) to sell a specified quantity of a security at a specified price (strike price) within a fixed period of time (until its expiration).

For the writer (seller) of a put option, it represents an obligation to buy the underlying security at the strike price if the option is exercised. The put option writer is paid a premium for taking on the risk associated with the obligation.

For stock options, each contract covers 100 shares.

Buying Put Options

Put buying is the simplest way to trade put options. When the options trader is bearish on particular security, he can purchase put options to profit from a slide in asset price. The price of the asset must move significantly below the strike price of the put options before the option expiration date for this strategy to be profitable.

A Simplified Example

Suppose the stock of XYZ company is trading at $40. A put option contract with a strike price of $40 expiring in a month's time is being priced at $2. You strongly believe that XYZ stock will drop sharply in the coming weeks after their earnings report. So, you paid $200 to purchase a single $40 XYZ put option covering 100 shares.

Say you were spot on and the price of XYZ stock plunges to $30 after the company reported weak earnings and lowered its earnings guidance for the next quarter. With this crash in the underlying stock price, your put buying strategy will result in a profit of $800.

Let's take a look at how we obtain this figure.

If you were to exercise your put option after earnings, you invoke your right to sell 100 shares of XYZ stock at $40 each. Although you don't own any share of XYZ company at this time, you can easily go to the open market to buy 100 shares at only $30 a share and sell them immediately for $40 per share. This gives you a profit of $10 per share. Since each put option contract covers 100 shares, the total amount you will receive from the exercise is $1000. As you had paid $200 to purchase this put option, your net profit for the entire trade is $800.

This strategy of trading put option is known as the long put strategy.

Protective Puts

Investors also buy put options when they wish to protect an existing long stock position. Put options employed in this manner are also known as protective puts. Entire portfolio of stocks can also be protected using index puts.

Selling Put Options

Instead of purchasing put options, one can also sell (write) them for a profit. Put option writers, also known as sellers, sell put options with the hope that they expire worthless so that they can pocket the premiums. Selling puts, or put writing, involves more risk but can be profitable if done properly.

Covered Puts

The written put option is covered if the put option writer is also short the obligated quantity of the underlying security. The covered put writing strategy is employed when the investor is bearish on the underlying.

Naked Puts

The short put is naked if the put option writer did not short the obligated quantity of the underlying security when the put option is sold. The naked put writing strategy is used when the investor is bullish on the underlying.

For the patient investor who is bullish on a particular company for the long haul, writing naked puts can also be a great strategy to acquire stocks at a discount.

Put Spreads

put spread is an options strategy in which equal number of put option contracts are bought and sold simultaneously on the same underlying security but with different strike prices and/or expiration dates. Put spreads limit the option trader's maximum loss at the expense of capping his potential profit at the same time.
