Stock Options - Definition
Stock Options are contracts that grant the holder the right to buy or sell a specific stock at a specific price before the contract expires.
What Are Stock Options?
Since the early 70s, stock options have become one of the most important derivative instrument besides stock futures. Stock Options
are simple contracts that allow the owners to buy or sell a stock at a specific price before it expires, yet, that simplicity has
made Stock Options one of the most versatile speculative and hedging instrument ever created, elevating options trading to its current level
of importance.
Lately, gurus such as Robert Kiyosaki has popularized the use of Stock Options and Options Trading as a way of investing for greater rewards for little risk.
So, what exactly are Stock Options?
If you have ever purchased a home, you would have signed something called an "Option To Purchase". That "Option To Purchase" makes sure that
the seller of that house makes it available for sale the moment you decide to exercise that option at the price agreed in the option.
That is exactly the same when you purchase Stock Options.
The seller of the Stock Options is obligated to sell you the underlying stocks at the price agreed in the Stock Options contract the moment you decide to exercise
that option. Such Stock Options are known as Call Options. Stock Options which allows you to SELL your current shares at an agreed price in the
future are known as Put Options.
Call & Put Stock Options
If you own Call Options, which are Stock Options contracts allowing you to buy the stock in future at the current agreed price, and the stock
rallies strongly, that call option becomes more and more valuable due to the fact that you are able to still buy it at the lower agreed price
from the seller of the Stock Options if you should exercise the Stock Options.
|
Example : Assuming XYZ company shares are trading at $40 right now. You bought a call stock options contract that allows you to buy XYZ shares
at $40 anytime before it expires in 2 months. 1 month later, XYZ company shares are trading at $50 but you still own the right to buy
it at $40 through the call stock options.
|
Stock Options Trading is exactly like 2 persons betting against each other. The person who speculates that the price of the stock is going to do badly
would sell Call Stock Options to the other person who speculates that the price of the stock is going to go up. If the stock drops, the seller of
the call stock options, known as the "writer", wins and gets to pocket the money the buyer paid for the Stock Options. If the stock rises,
the seller of the call stock options is obligated to still buy the stocks at the lower price from the buyer, known as the "holder", and loses money.

Conversely, if you own Put Options, which are Stock Options contracts allowing you to SELL your current stocks in future at the current agreed
price, and the stock ditches, that put option becomes more and more valuable due to the fact that you are still able to sell your stock at the
higher agreed price to the seller of the put stock options!
|
Example : Assuming you own XYZ company shares trading at $40 right now. You bought a put stock options contract that allows you to sell your XYZ shares
at $40 anytime before it expires in 2 months. 1 month later, XYZ company shares are trading at $30 but you still own the right to sell
it at $40 through the put stock options.
|
In this case, the seller of the put options is speculating that the price of the stock would go up while the buyer of the put options is speculating that the price of the stock would go down. If the stock rises, the buyer of the put options would obviously not exercise the put option's rights to sell his
stocks at the lower price and would just let the put stock options expire, allowing the seller of the put options to pocket the money paid by the buyer for
those stock options. If the stock falls, the buyer of the put options would still be able to sell the stocks to the seller at the higher price agreed, making a profit out of the seller.
In a nutshell, the buyer of call stock options profits when the stock goes up and the buyer of put stock options profits when the stock goes down.
Conversely, the seller of call stock options profits when the stock goes down and the seller of put stock options profits when the stock goes up.
Stock Options Contract Specifications
Every stock options contract traded in the Stock Options Trading Exchanges are written with the following standardized specifications. This is why
they are also known as Standardized Options.
Underlying Stock : Each Stock Options contract is written for a specific stock.
Strike Price : The "agreed price" which was referred to very often above. This is the price at which buyers of call options
can buy the stock at in future and is also the price at which buyers of put options can sell the stock at in future.
Expiration Date : The date at which a Stock Options Contracts expires. Buyers of Stock Options need to exercise or sell the stock options
before this date. The further away the expiration date is, the more expensive the stock options become.
Lot Size : The number of shares of the underlying stock that is represented with each stock options contract. In the US market, each Stock Options
contract usually represents 100 shares of the underlying stock.
Type Of Option : Whether it is a call option or a put option.
Terms Of Delivery : Call option sellers must sell and deliver the underlying stock to the buyer if exercised and put option sellers must
buy the underlying stock from the buyer if exercise by cash.
Parties In Stock Options Transactions
There are basically 2 parties to a Stock Options transaction. A buyer and a seller. Any individual can be a buyer or a seller of call or put
stock options through the various stock options exchanges. You could buy a call option and you could also sell a call option if you want to.
So, who is this other party you are trading with? When you trade exchange traded stock options, you are in fact trading with a professional
institution or individual known as Market Makers. Market makers buy from you when you want to sell and sell to you when you want to buy.
Market makers essentially guarantees liquidity in the stock options trading market.
|
Many stock options traders actually look upon Market Makers as bookies!

Types Of Stock Options
Stock Options are traded in several forms:
Exchange Traded Stock Options : These are Stock Options which anyone can trade with in the public stock options trading exchanges through
a broker. They are also known as "Listed Options".
Over-The-Counter (OTC) Stock Options : These are Stock Options which are highly customized and traded in Over-The-Counter (OTC) markets
which are less liquid and less assessible to the public.
Exotic Options : Exotic options are Stock Options that are highly customized and complex and usually traded only in OTC markets. Read
all about Exotic Options.
Employee Stock Options : Stock Options given to employees by their companies. The company in this case acts as the seller of the stock
options to employees and usually gives these Employee Stock Options as incentives. Read
all about Employee Stock Options.
|
You are trading with exchange traded stock options when you open a brokerage account to trade options of publicly listed companies. This is the
most common form of stock options trading and is highly assessible to the public. Employee stock options on the other hand are stock options
given to employees by companies which are either listed or private. Employee Stock Options granted by private companies can only be exercised
against the company itself as there is no active secondary market on which they can be sold.
|
Styles Of Stock Options
There are 2 styles of Stock Options; European Style Options and American Style Options. These names have nothing to do with where the stock options
are traded as most exchange traded stock options are American Style Options even in Europe. European Style Options and American Style Options
are really different in the way they handle when you can exercise the options. By exercising the options, we mean exercising the right to buy
or sell the underlying asset in accordance to the terms of the stock options contract. European Style Options allows its holders to exercise
only upon expiration while American Style Options allows its holders to exercise anytime they want to before expiration. The flexibility of
American Style Options also made it more expensive than European Style Options and also created problems with finding a correct way to price that
flexibility.
All exchange traded stock options in the US market are American Style Options which you can exercise at anytime you want to. Many exchange traded
options in countries such as Singapore are European Style Options and are known as "Warrants".
The benefit of being able to exercise options early and paying a premium for such a benefit is really detrimental to options traders who seldom
exercise stock options. When stock options positions become profitable, options traders rather sell the stock options for an equal
profit rather than exercise the options.

Benefits Of Trading Stock Options
So, why trade Stock Options when you can also profit from both upwards and downwards move through buying and shorting shares? Why trade
Stock Options when you can trade stock futures for even greater leverage? There are 3 important reasons why Stock Options are better than
just trading stocks or futures and they are Leverage, Protection and Flexibility.
Leverage Of Stock Options
As Stock Options cost only a small fraction of the price of the underlying stock while representing the same amount of shares, it allows
anyone to control the profits on the same amount of shares with a much smaller amount of money. With the same amount of money that you
would have spent on buying shares, that same amount of money would allow you to control a much bigger amount of that stock through buying its
Stock Options. The power to control more shares with lesser money produces leverage.
|
Example : Assuming you have $1000 to invest on the shares of XYZ company trading at $40. Its $40 strike price call options is trading
at $2.00. You could control 25 shares ($1000 / $40 = 25) of XYZ company through buying its stocks or you could control 500 shares of
XYZ company through buying 2 contracts of its call options ($1000 / $2 = 500)
|
Being able to control more shares with the same amount of money also means that profitability is far greater trading Stock Options on the
same amount of money relative to trading stocks.
Example : Assuming XYZ company rallies from $40 to $60.
Buying Shares: ($60 - $40) x 25 = $500 profit
Buying Call Options: ($60 - $40) x 500 = $10,000 profit
|
As you can see from the example above, buying call options would produce 20 times more profits than buying shares, which means that buying call
options in this case produces 20 times the leverage of buying stocks!
Learn how to trade call options properly through the Long Call Options strategy.
On top of that, Stock Options leverage or "gearing" can be precisely calculated and variable as the Options Moneyness changes. Typically,
In The Money Options produce less leverage while Out Of The Money Options produce more leverage.
Due to the variable nature of Stock Options leverage, many different trading styles can be applied successfully using Stock Options. Long term
options trading strategy would employ lesser leverage while day trading strategies would employ greater leverage.
Stock Options leverage also allows investors with a small amount of money to control significant amount of shares of companies which would be
otherwise too expensive to own.
|
Example : ABC company is trading at $700 per share while its $700 strike price call options are trading at $15. If you have only $1500 to invest,
you would only be able to buy 2 shares of ABC company stocks while you would be able to control 100 shares of ABC company stocks if you bought
1 contract of its call options for $1500.
|
Protection Of Stock Options
Buying Stock Options is like buying insurance. Buying a put option allows you to always be able to sell your stocks at the strike price no matter
how low the stock falls to. This is known as a
Protective Put. Indeed, Stock Options started out as a hedging instrument more than a speculative
instrument. Stock Options allows stock traders to hedge away directional risk anytime they want to, conveniently and without margin implications.
|
Example : Assuming you own XYZ company shares trading at $40 right now. You bought a put stock options contract that allows you to sell your XYZ shares
at $40 anytime before it expires in 2 months. 1 month later, XYZ company shares are trading at $30 but you still own the right to sell
it at $40 through the put stock options.
|
Furthermore, as Stock Options allows you to control the same amount of shares at a much lesser price, you can risk lesser capital on every
trade using Stock Options, thus reducing capital exposure to risk. Unlike futures, Stock Options have no margin requirement and the maximum
loss is limited to the amount of money paid on the Stock Options contracts. One such method of utilizing call options is known as the
Fiduciary Call.
Flexibility Of Stock Options
Stock options grants stock and option traders the flexibility to change from one market opinion to another without significantly changing
your current holdings through the use of
Synthetic Positions
and
Synthetic Options Strategies. Yes, you can
structure a position to profit even if the stocks you are holding falls!
In fact, stock options can sometimes be safer than just trading stocks! Read about
How Stocks Is Riskier Than Options.
Risks of Stock Options
The single most significant risk of Stock Options is definitely the fact that if it expires
out of the money, the stock options contract
expires worthless and you lose all the money you put into buying that stock options contract. If you put all your money into a single
stock options contract and it expires out of the money, you will lose all your money. That is why understanding
Options Moneyness and having
a sensible trade management strategy is so important in options trading.
The second most significant risk in Stock Options Trading is known as "Time Decay". Stock Options contracts are sold for a price,
a kind of compensation to the seller for taking the extra risk. However, as Stock Options contracts draw nearer to expiration, the risk to seller
reduces and the value of the stock options diminshes. What this means in options trading is that if you bought a call option and the stock
don't rally fast enough, time decay will take back so much of the value that the call options may not be profitable even if the stock
went up. Fortunately, time decay can be measured through the
options greeks so that they can be
hedged away.
There are many more risks to Stock Options Trading that are more technical in nature.

How Are Stock Options Priced?
Stock Options contracts consists of 2 main price components, the
Intrinsic Value and the
Extrinsic Value. In a nutshell,
Intrinsic value is the portion of the underlying stock's value that is already built into the stock options contract. Call options
have intrinsic value when the stock moves up, building value into the call option which has the right to still buy at the lower price.
Put options have intrinsic value when the stock moves down, building value into the put option which has the right to still sell at the
higher price. Intrinsic value is therefore pretty straight forward and is the main component of profiting from stock options trading.
Extrinsic value is the tricky bit. Like insurance, Stock options contracts comes with a price to own whether or not they get exercised.
This price is a way of compensating the seller of stock options for taking the extra risk. This price, or Extrinsic Value, and how to
price it properly still baffles the finance world today. The question is, how much should sellers of stock options be compensated
in the prevailing circumstances? Many factors come into play and the most popular stock options pricing model is no doubt
the Black-Scholes Model. As stock options
consist only of the extrinsic value, which is frequently just a few cents, and a small fraction of the price of the underlying
stock in intrinsic value, if any, stock options costs only a fraction of the price of the underlying stock, creating financial leverage.
Options Traders who hold each stock options contract to expiration usually do not bother too much with how extrinsic value is calculated and
whether or not they are getting a good deal. These Stock Options Traders simply take the price they pay on the stock options as an expense
, just like an insurance premium, and aim to buy stock options on stocks that are likely to move more than the price paid on them.
How Do We Profit From Stock Options?
In a nutshell, options traders profit from Stock Options trading through 2 main avenues; From a move in the underlying stock or time decay
through selling stock options. Profiting from a move in the underlying stock is probably the most popular way of profiting in stock options trading.
options traders who buy call options wants to profit from the build up in intrinsic value as the stock goes higher and higher.
Conversely, options traders who buy put options wants to profit from the build up in intrinsic value as the stock goes lower and lower.
|
Example : Assuming XYZ company shares trading at $40 right now. You bought a put stock options contract that allows you to sell your XYZ shares
at $40 anytime before it expires in 2 months for $2.00 per contract. During expiration, XYZ company shares are trading at $30 but you still own the right to sell
it at $40 through the put stock options. An intrinsic value of $10 has been built up into the put options, making the put options worth $10
at expiration. Since you paid $2 to own the put options and get to sell those put options for $10 now, a $8 profit results.
|
There are also options traders who would rather "play the bookie" and become writers or sellers of stock options. When you sell stock options,
you receive the extrinsic value or price of the options as compensation for taking on that extra risk. When the opinion of the buyer of those
stock options is wrong, you get to pocket the price of the options as profits.
|
Example : Assuming XYZ company shares trading at $40 right now. You sold a put stock options contract that expires in 2 months for $2.00 per contract. During expiration, XYZ company shares are trading higher at $50. Since the price of XYZ company is now higher at $50, the right to sell shares of
XYZ company at $40 becomes worthless, or out of the money, and you pocket the $2.00 from the sale of the put options as profit.

Options Strategies. We have a list of
all options strategies here in our Options Strategy Library.

Brief History Of Stock Options
Options contracts goes a long way back to about 332 B.C. where it was used to secure the rights to use olive presses as well as back in the
tulip mania of 1636 in Europe. The first real stock options were created back in 1872 by American Financier Russell Sage who invented the
first call and put options to be traded in Over The Counter (OTC) markets. Yes, stock options were first traded as unstandardized contracts
which has no standard pricing model nor terms. Sellers simply charged a price they felt was reasonable, resulting in very inefficient markets.
With the creation of the Chicago Board Of Options Exchange (CBOE), which is still the biggest stock options exchange in the world today, in 1973
and the invention of the Black-Scholes Option Pricing Model in the same year, call and
put options are at last standardized and accessible to the general public. For the first time, any member of the public may buy and sell
stock options. The Options Clearing Corporation or OCC, was then created as a guarantor for all stock options contracts, guaranteeing the performance
and delivery of every stock options contract. This combination created the modern, standardized and highly efficient options trading market
that we have today.
By 1976, the American Stock Exchange, Philadelphia Stock Exchange as well as the Pacific Exchange also begun trading stock options as demand for
stock options increased exponentially.
