Option Basics

You now have enough information to understand some hypothetical call and

put options. These two assets – calls and puts – are the building blocks for every

option strategy you will ever encounter. This is why it is crucial that you understand

the rights and obligations that they convey. Most confusion with option strategies

stem from not understanding (or simply forgetting) who has the right and who has

the obligation.

Because options are binding contracts, they are traded in units called
contracts.

Stocks are traded in shares; options are traded in contracts. An option contract, just

like a pizza coupon, will always be designated by the underlying stock it controls

along with the expiration month and strike price. For example, let’s assume we are

looking at a Microsoft June $30 call.

We’ll soon show you where you can look up actual option quotes and symbols for

options, but for now let’s make sure you understand what this option represents.

Using your understanding of pizza coupons, what do you suppose the buyer of

one contract is allowed to do? The buyer of this call has the right (not the obligation)

to purchase 100 shares of the underlying stock – Microsoft – for $30 per share at

any time through the third Friday in June. (Remember that the expiration date

for stock options is always the third Friday of the expiration month.) The buyer of

this coupon is “locked in” to the $30 price no matter how high Microsoft shares

may be trading. Obviously, the higher Microsoft trades, the more valuable the call

option becomes.

To understand this concept a little better, assume that you have found a piece

of property valued at $300,000 and wish to buy it. But you’d first like spend a few

days researching the area before buying it. If you do, you’ll run the risk of losing

it to another investor. What can you do? You can go to the broker and put down

some money to hold the property for you. For instance, you may pay $500 for

several days worth of time. If you decide against the property, you lose the $500.

These arrangements are done all the time in real estate and are called “options” on

real estate. Assume that you pay the $500 for five days worth of time and are now
locked into a binding agreement to buy the property for $300,000 over the next

five days. Now suppose that some news is spreading that the area is about to be

commercially zoned and some big businesses are interested in it. Property in the

area goes up dramatically overnight. But even if you decide to not buy the property,

don’t you think that somebody else would love to be in possession of the contract

that you have giving them the right to pay $300,000? Of course they would. And

these people will start offering you large amounts of money to persuade you to sign

over the contract to them. You could just sell it to them and they could sell it to

others. This is exactly what most traders do with the equity options market.

Now let’s go back to our option example. How much will it cost you to

use (exercise) your call option? Because you are buying 100 shares of stock, the

strike price must be multiplied by 100 as well. (The number “100” is called the

“multiplier” of the option for this reason.) If you were to exercise this Microsoft

$30 call option, you would pay the $30 strike * 100 shares = $3,000 cash. This is

called the
total contract value or the exercise value. In exchange for that payment,

you’d receive 100 shares of Microsoft. It works just like a pizza coupon. You pay

a fixed amount of cash and receive some type of underlying asset. Most brokers

charge a standard stock commission to exercise your options. If you exercised this

call, your broker would probably charge you his regular commission for buying

100 shares of stock. After all, the long call option is simply a means for buying

regular shares of stock.

To restate a previous point, it is important to understand that if you buy call

or put options, you are not required to ever buy or sell shares of stock. Further,

you do not ever need the shares of stock in your account at any time. Most option

contracts are opened and closed in the open market without a single share of stock

changing hands. Even though you're allowed to purchase or sell stock with your

options, most traders never do. Instead, they just buy and sell the contracts in the

open market amongst other traders.

Now let’s assume we are looking at a Microsoft June $30 put option. Think

about your auto insurance policy and try to figure out what this option allows

you to do. If you buy this put option, you have the right to sell 100 shares of

Microsoft for $30 per share at any time through the third Friday in June. Because

you are locking in a selling price, put options become more valuable as the stock

price falls. If you exercise this put option, you are selling 100 shares of Microsoft,
which means you will have 100 shares of Microsoft taken from your account and

delivered to someone else. In exchange, you will receive the $30 strike * 100 shares

= $3,000 cash. If you exercise this put, your broker will probably charge the regular

stock commission for selling 100 shares of stock since the put option is simply a

means for selling regular shares of stock.

What if you only wish to buy or sell fewer than 100 shares of stock? You can

do that but in a roundabout way. Using the call example above, let’s say you only

wanted to buy 60 shares of Microsoft for $30. You would still exercise the call

option for 100 shares and then immediately submit an order to sell 40 shares

(which would carry a separate commission). Each contract is good for 100 shares

and you must buy and sell in that amount. But there’s nothing stopping you from

immediately entering another order to customize those amounts to suit your needs.

Likewise, if you exercised a put option but only wanted to sell 60 shares of stock,

you would have to exercise the put and sell 100 shares and then immediately place

an order to buy 40 shares.
