"Long" and "Short"



The Long and Short of It


he financial markets are filled with colorful terminology. 
And one of the biggest obstacles that new option investors face is 
interpreting the jargon. Two common terms used by brokers and 
traders are “long” and “short,” and it’s important to understand 
these terms as applied to options.
If you buy any financial asset, you are “long” the position. For 
example, if you buy 100 shares of IBM, using market terminology, you are long 
100 shares of IBM. he term “long” just means you own it. Likewise, if you buy a 
call option, you are “long” the call option. 
If  “long” means you bought it then “short” means you sold it, right? Not quite. 
Some people will tell you that “short” just means you sold an asset, but that is an 
incomplete definition. For example, if you are long 100 shares of IBM and then 
sell 100 shares you are not short shares of IBM even though you sold 100 shares. 
hat’s because you bought the shares first and then sold them, which means you 
have no shares left. 
However, let’s say you bought 100 shares of IBM and then, by accident, entered 
an order online to sell 150 shares of IBM. he computer will execute the order 
since it has no way of knowing how many shares you actually own. (Maybe you 
have shares in a safe deposit box or with another broker.) But if you really owned 
only 100 shares then you would be “short” 50 shares of IBM. In other words, you 
sold 50 shares you don’t own. And that’s exactly what it means to be short shares of 
stock. It means you sold shares you do not own. However, when we short shares in 
the financial market, it’s not meant to be by mistake – it is done intentionally. How 
can you intentionally sell shares you don’t own? You must borrow them. In order 
to further understand what it means to be “short” and how that applies to options, 
let’s take a quick detour to understand the basics of short selling.
Traders use short sales as a way to profit from falling stock prices. Assume IBM 
is trading for $70 and you think its price is going to fall. If you are correct, you 
could profit from this outlook by entering an order to “short” or “sell short” shares 
of IBM. Let’s assume you decide to short 100 shares. Your broker will find 100 
shares from another client and let you borrow these shares. Although this sounds 
like a lengthy, complicated transaction it takes only seconds to execute.




In terms of the mechanics, shorting shares is similar to making a purchase on 
your credit card. Your bank finds loanable funds from somebody else’s account 
to let you borrow and you then have an obligation to return those funds at some 
time. How complicated is it to short shares of stock? About as complicated as it is 
to swipe a credit card at a cash register. 
Let’s assume you short 100 shares of IBM at $70. Once the order is executed, 
you have $7,000 cash sitting in your account (sold 100 shares at $70 per share) 
and your account shows that you are short 100 shares of IBM – you sold shares 
that you do not own. Do you get to just take the $7,000 cash, close the account 
and walk away? No, once you short the shares of stock, you incur an obligation to 
replace those 100 shares at some time in the future. In other words, you must buy 
100 shares at some time and return them to the broker. Obviously, your goal is to 
purchase those 100 shares at a cheaper price.
Let’s assume that the price of IBM later drops by $5 to $65 and you decide to 
buy back the shares. You could enter an order to buy 100 shares and spend $6,500 
of the $7,000 cash you initially received from selling shares. Once you buy the 100 
shares, your obligation to return the IBM shares is then satisfied and you are left 
with an extra $500 in your account. In other words, you profited from a falling 
stock price. his profit can also be found by multiplying the number of short 
shares by the drop in price, or 100 shares * $5 fall in price = $500 profit. If you 
have shorted 300 shares of IBM, you would have ended up with a 300 shares * $5 
fall in price = $1,500 profit. Of course, if the price of IBM had risen at the time 
you purchased them back, then you’d be left with a loss since you must spend more 
than you received to return the shares. If short selling still sounds confusing, just 
realize that the short seller generates profits in the same way as a stock buyer but by 
entering transactions in the opposite order. For instance, when you buy stock, you 
want to buy low and sell high. When you short stock, you want to sell high and 
buy low. If you short a stock and then buy it back at a higher price, you’re left with 
a loss because you really bought high and sold low. 
Short selling works because traders are obligated to return a fixed number of 
shares and not a fixed dollar amount. In our example, you shorted 100 shares with 
a value of $7,000. Your obligation is to return 100 shares of IBM and not $7,000 
worth of IBM. If you can purchase the shares for less money than you received, 
you will make a profit.




his is not meant to be a course in shorting stocks but rather a way to understand 
what the term “short” really means when applied to the stock or options market. 
Shorting means you receive cash from selling an asset you don’t own and then incur some 
type of obligation. In the case of shorting stocks, your obligation is that you must 
buy back the shares at some time. 
If you short an option, you have sold something you don’t own. You get 
cash up front and then incur some type of obligation depending on whether 
you sold a call or put. If you short a call, you get cash up front and have the 
obligation to sell shares of stock. If you short a put, you get cash up front and 
have the obligation to buy shares of stock. he cash is credited to your account 
immediately and is yours to keep regardless of what happens to the option. hat 
is your compensation for accepting an obligation, much like the premiums you 
pay to an insurance company.




When you sell (short) an option you will receive cash, which is yours to keep 
regardless of what happens in the future.




The following table may help you to visualize the rights-versus-obligations relationships:
LONG                                                                    SHORT
Call Right to buy stock                                    Obligation to sell stock
Put Right to sell stock                                     Obligation to buy stock

Notice that the long and short positions are taking opposite sides of the 
transaction. For instance, the long call (call buyer) must be matched with a short 
call (call seller). he long call has a  right while the short call has an  obligation.
Rights and obligations are opposites. In addition, the long call gets to buy while the 
short call is required to sell. Buying and selling are also opposites. 
For put options, the long put (put buyer) must be matched with a short put 
(put seller). As with call options, it is the long position that has the right while the 
short position has the obligation (opposites). he long put, however, has the right 
to sell while the short put is required to buy (opposites). 

his arrangement is required to make the options market work. Both parties 
(the buyer and seller) cannot have rights. hey can neither both buy nor both sell. 
One side has the right to buy (or the right to sell), while the opposite side has the 
obligation to complete the transaction.
his arrangement is often a source of confusion for new traders. hey wonder 
how the option market can work if everybody has a right to buy or sell. he answer 
is that it is only the  long position that has the rights. he  short position has an 
obligation. It is important to understand this relationship when going through this 
book, especially when you get to strategies.


Note : Long options have rights. Short options have obligations

Getting Out of a Contract


We just learned that you can get into an option contract by either 
buying or selling a call or put. But once you’re in the contract, is there a 
way to get out of it at a later time? he answer is yes. All you have to do 
is enter a closing transaction (also called a reversing trade). In other words, you can 
always “escape” your obligations by simply doing the reverse set of actions that got 
you into the contract in the first place. 
For example, if you are short an option and decide at a later time you don’t want 
the corresponding obligation, you can get out of it by simply buying the options 
back. his is much like you do with shares of stock if you are short. However, just 
because you can get out of the contract doesn’t mean that you can avoid any losses 
that may have accrued. he price you pay to get out of the contract may be higher 
and, in some cases, much higher than the price you originally received from selling 
it – just as when shorting shares of stock. But the point is that you can get out of a 
short option contract by simply buying it back.
If the idea of buying back a contract sounds confusing, think of the following 
analogy. You probably have a cell phone are locked into some type of agreement such 
as a one-year contract. Cell companies do this to prevent people from continually 
shopping around and jumping to the hot promotion of the month. However, your cell provider will also have some type of “buy back” clause in the contract. hat is, 
if you wish to get out of the agreement, you must pay a fixed amount of money, 
perhaps $200, and you can escape your remaining obligations. If you pay this fee, 
the company cannot take you to court later and say that you didn’t fulfill your 
obligations. he reason is that you bought the contract back – it no longer exists 
between you and the company. hat’s the fee they specified to end all obligations.
his is mathematically the same thing that happens when you buy back a 
contract in the options market. Although it is not a fee to end the contract, what 
you’re really doing is going long and short the same contract, thereby eliminating 
all profits or losses beyond that point. If you’re long the contract and you’re short 
the same contract, then you’ve effectively ended all obligations.
Likewise, you can get out of long call option by simply doing the reverse; 
that is, selling the same contract that you own. Because of this possibility, most 
option traders simply trade the contracts back and forth in the open market rather 
than using them to buy or sell shares of stock. As we will later see, trading option 
contracts is a big advantage because they cost a fraction of the stock price.

Note:You can always get out of an option contract at any time by simply entering 
a reversing trade. 

Let’s make sure you understand the concepts of long and short calls and puts 
by using our pizza coupon and car insurance analogies. If you are in possession of 
a pizza coupon, you are “long” the coupon and have the right, not the obligation, 
to buy one pizza for a fixed price over a given time period. In the real world, you 
do not buy pizza coupons; they are handed out for free. But that doesn’t put an 
end to our analogy because the basic idea is still there. Since you are holding the 
coupon, that means you posess the right to use it, and that’s the role of the long 
position. he pizza storeowner would be “short” the coupon and has an obligation
to sell you the pizza if you choose to use your coupon. You have the right; he has 
the obligation.

If you buy an auto insurance policy you are “long” the policy and have the 
right to “put” your car back to the insurance company. he insurance company 
is “short” the policy; it receives money in exchange for the potential obligation of 
having to buy your car from you. Whether you make a claim or not, the insurance company keeps your premium just as you will when selling options. hat’s its 
compensation for accepting the risk. 
In the real world of car insurance, you cannot just force the insurance company 
to buy the car back for any reason. here are certain conditions that must be 
met; for example, the car must be damaged or stolen. You can’t just obligate the 
insurance company because you don’t like it anymore or because it has depreciated. 
However, in the real world of put options, you can sell your stock at a fixed price 
for any reason while your put option is still in effect. here are no restrictions. Of 
course, you wouldn’t want to do that if the fixed price you’d receive is less than the 
current market price. he main point is that if you are long a put option, you call 
the shots. You have the rights. You have the “option” to decide. You have the right 
to sell your stock for that fixed price at any time during the time your “policy” is 
in effect. 



The Options Clearing Corporation (OCC)
Okay, this may sound good in theory but how do you know that the short 
positions will actually follow through with their obligations if you decide to use 
your call or put option? 
he answer is that there is a clearing firm called the Options Clearing Corporation,
or OCC. he OCC is a highly capitalized and regulated agency that acts as a 
middleman to all transactions. When you buy an option, you are really buying 
it from the OCC. And when you sell an option, you are really selling it to the 
OCC. he OCC acts as the buyer to every seller and the seller to every buyer. It 
is the OCC that guarantees the performance of all contracts. By performance we 
obviously do not mean profits but rather that if you decide to use your option, 
you are assured the transaction will go through. In fact, ever since the inception 
of the options market and the OCC in 1973, not a single case of unfair or partial 
performance has ever occurred. If you’d like to read more about the OCC, you can 
find their website.

Key Concepts
1) Long call options give the buyer the right to BUY stock at a fixed price over a 
given time period.
2) Short call options create the obligation to SELL stock at a fixed price over a 
given time period.
3) Long put options give the buyer the right to SELL stock at a fixed price over a 
given time period.
4) Short put options create the obligation to BUY stock at a fixed price over a 
given time period.
5) Option sellers (calls or puts) keep the cash regardless of what happens in the 
future.
6) he OCC acts as a middleman to all transactions.
