Options: The Basics

After your introduction, you may be asking, so, what are these option things, and why would anyone consider using them?

Options represent the right (but not the obligation) to take some sort of action by a predetermined date. That right is the buying or selling of shares of the underlying stock.  

There are two types of options, calls and puts. And there are two sides to every option transaction -- the party buying the option, and the party selling (also called writing) the option. Each side comes with its own risk/reward profile and may be entered into for different strategic reasons. The buyer of the option is said to have a long position, while the seller of the option (the writer) is said to have a short position.

Option Trades

Call Buyer (Long Position) Call Seller (Short Position)

Put Buyer (Long Position)

Put Seller (Short Position)

Note that tradable options essentially amount to contracts between two parties. The companies whose securities underlie the option contracts are themselves not involved in the transactions, and cash flows between the various parties in the market. In any option trade, the counterparty may be another investor, or perhaps a market maker (a type of middle man offering to both buy and sell a particular security in the hopes of making a profit on the differing bid/ask prices).

What's a call option?
A call is the option to buy the underlying stock at a predetermined price (the strike price) by a predetermined date (the expiry). The buyer of a call has the right to buy shares at the strike price until expiry. The seller of the call (also known as the call "writer") is the one with the obligation. If the call buyer decides to buy -- an act known as exercising the option -- the call writer is obliged to sell his/her shares to the call buyer at the strike price.

So, say an investor bought a call option on Intel (Nasdaq: INTC) with a strike price at $20, expiring in two months. That call buyer has the right to exercise that option, paying $20 per share, and receiving the shares. The writer of the call would have the obligation to deliver those shares and be happy receiving $20 for them. We'll discuss the merits and motivations of each side of the trade momentarily.

What's a put option?
If a call is the right to buy, then perhaps unsurprisingly, a put is the option to sell the underlying stock at a predetermined strike price until a fixed expiry date. The put buyer has the right to sell shares at the strike price, and if he/she decides to sell, the put writer is obliged to buy at that price.

Investors who bought shares of Hewlett-Packard (NYSE: HPQ) at the ouster of former CEO Carly Fiorina are sitting on some sweet gains over the past two years. And while they may believe that the company will continue to do well, perhaps, in the face of a potential economic slowdown, they're concerned about the company sliding with the rest of the market, and so buy a put option at the $40 strike to "protect" their gains. Buyers of the put have the right, until expiry, to sell their shares for $40. Sellers of the put have the obligation to purchase the shares for $40 (which could hurt, in the event that HP were to decline in price from here).

Why use options?
A call buyer seeks to make a profit when the price of the underlying shares rises. The call price will rise as the shares do. The call writer is making the opposite bet, hoping for the stock price to decline or, at the very least, rise less than the amount received for selling the call in the first place.

The put buyer profits when the underlying stock price falls. A put increases in value as the underlying stock decreases in value. Conversely, put writers are hoping for the option to expire with the stock price above the strike price, or at least for the stock to decline an amount less than what they have been paid to sell the put.

We'll note here that relatively few options actually expire and see shares change hands. Options are, after all, tradable securities. As circumstances change, investors can lock in their profits (or losses) by buying (or selling) an opposite option contract to their original action.

Calls and puts, alone, or combined with each other, or even with positions in the underlying stock, can provide various levels of leverage or protection to a portfolio.

  • Option users can profit in bull, bear, or flat markets.
  • Options can act as insurance to protect gains in a stock that looks shaky.
  • They can be used to generate steady income from an underlying portfolio of blue-chip stocks.
  • Or they can be employed in an attempt to double or triple your money almost overnight.

But no matter how options are used, it's wise to always remember Robert A. Heinlein's acronym: TANSTAAFL (There Ain't No Such Thing As A Free Lunch). Insurance costs money -- money that comes out of your potential profits. Steady income comes at the cost of limiting the prospective upside of your investment. Seeking a quick double or treble has the accompanying risk of wiping out your investment in its entirety.

The Foolish bottom line
Options aren't terribly difficult to understand. Calls are the right to buy, and puts are the right to sell. For every buyer of an option, there's a corresponding seller. Different option users may be employing different strategies, or perhaps they're flat-out gambling. But you probably don't really care -- all you're interested in is how to use them appropriately in your own portfolio.

    @ Dave,

    If you buy a put and the stock decreases in value, then the put decreases in value, so it is a short position. If you buy full coverage car insurance, and you decrease the value of the car by crashing it, the insurance suddenly increases a lot in value, as it pays off your car. So in a sense, car insurance is going short position on your car's condition, life insurance is going short on your life, medical insurance is short on your health, house insurance is short on your house's structural integrity, and so on.

    If you by a put, you are gaining the right to sell the stock at a guaranteed price. You are limiting your potential losses because you will not have to sell below that price. Because of the leverage of options, you can use a small amount of money to buy a put but have your losses completely covered if the stock drops.

    You can use buy a put outright to go short on a stock or use it in conjunction with stock you own as insurance.

    I think they are just making the point that if you are writing options contracts and selling them to open, you are hoping you are selling at the best possible price and that the price of the option will go down after that point. In that sense any time you sell something you are 'short' on it. Buying a put would be long on the put, short on the underlying asset.

    When you take a short position and the stock goes higher you have liability of the difference between your short position and the price of the stock. You can have unlimited liability.

    In the case of an option your only at risk the cost of the option itself. So options are a cheaper and less expensive way to protect gains.

    Or so I think,

    Depends on the exercise style of the option.If it's American Style then you can exercise any time on or before Expiration. European-style option contracts may only be exercised at the option's expiration date.

    I can see a lot of debate goin on with the table

    Option Trades

    Call Buyer (Long Position) Call Seller (Short Position)

    Put Buyer (Long Position)

    Put Seller (Short Position

    I agree to what JFrazer1 has to say about short selling and its 100% correct.

    But what the table meant was on a different note.We generally in fianace domain term Seller of a options having a short position and buyer of a option as having a long position.This is because the writter has an obligation to sell the option(Not with refrence to the underlyin secuirty. It is still buy in case of underlying instrument for put option.but in other words sellin of put option u can say.hope have not confused u all..) where as the will of a buyer persist.He may or may not buy the option contract.So it brings us to the defination of long and short positions.

    Long position:You have the right to collect the dividends or interest the security pays, the right to sell it or give it away when you wish, and the right to keep any profits if you do sell.

    Similarly, you have a long position in an option when you hold the option, and you have the right to exercise it before expiration or sell it.

    Short Position:The sale of a security or derivative, or the state of having sold one or the other. It is important to note that a short position is not closed, and is applied only to sales where further action may be required. For example, one who has borrowed securities and has then sold them is said to be have a short position with respect to that security, because he/she must eventually return an equivalent amount of the borrowed securities. Likewise, one who has sold (or written) an option is in a short position, because the option may be exercised at a later date.

    In short summarizing the whole story into:

    Buying(Buyer) of Call Option means buying of underlying insrtument which is a long position.

    Selling(Writter) of a Call Option means selling of underlying insrtument which is a short position.

    I think this was okie with all..

    Now buying (Buyer) of PUTOption means selling of underlying insrtument which is a long position with respect to the option bought as he has the right to buy the contract which in turn means selling the underlying instrument.

    Now Selling(Writter) of PUTOption means buying of underlying insrtument which is a short position with respect to the option sold as he has the obligation but not right (as it depends on the buyer) to sell the contract which in turn means buying the underlying instrument.The writer receives a premium from the buyer. If the buyer exercises his option, the writer will buy the stock at the strike price. If the buyer does not exercise his option, the writer's profit is the premium.So the writter is at short position with respect to the options instrument and not the underying instrument.

    I find this amusing. I have been reading Motley Fool for 7 months. I enjoy it so,much, I got a subscription. now the best thing I have learned from Fools has been to do the home work on stocks you want to invest in, using great informative articles tools like the crush ability chart and community board, ect... Also have been shown by David , and Warren to not let feelings get involved over the facts and hang in durning down turns. But as I read this article about option buying, it is greed and kind of a llness like betting and playing the market like it's a bookey. And gives me a better understanding why a great stock is up and down. My self I will continue the old school rules. But it is troubling to see Motley Fool to lower it self like this.And instead of investing more in tools to further my investing skills. I may have to start checking out Gum Shoe or seeking alpha. Please get back to focusing on up coming Rule Breakers. Please!

    I'm new to options, which is why I'm on this article, but it seems to me that for long term investors that don't want to play this game can still you options as a means to make a little extra money (in commission) and buy more stock of a company you love at lower price (one that you feel is below its intrinsic value).

    This can be accomplished with selling puts correct?
