Stock Options
At a very exclusive party, a high-class,
finely-clad woman slinked up to the CEO of a
Fortune 500 company and said, I will do anything
anything you want. The CEO flatly responded,
Re-price my options.

2What is an Option Contract?
- A security that gives the holder the right to buy
or sell a certain amount of an underlying
financial asset at a specified price for a
specified period of time - Financial asset examples Stocks, bonds, etc.
- Options contracts are not investments
- They are contracts between two investors
- Buyer of the option contract gets the right to
buy (or sell) the financial asset at a given
price for a given period of time - Seller of the option contract must buy (or sell)
the asset according to the terms of the contract
3What is an Option Contract?
(continued)
- Options contracts are part of a class of
securities called derivatives - Derivatives are securities that derive their
value from the price behavior of an underlying
real or financial asset - Options contracts have no voting rights, receive
no dividends nor interest, and eventually expire - Their value comes from the fact that they allow
the holder of the option to participate in the
price behavior of the underlying asset - With a much lower capital outlay
By the way, options contracts are usually just
referred to as options.
4What is an Option Contract?
(continued)
- Options allow an investor to leverage their
outlay of capital - Leverage the ability to obtain a given equity
position at a reduced capital investment, thereby
magnifying returns (review) - With options, you can make the same amount of
money from a stock or other security as if you
bought it for full price - But only come up 1/10th or less of the money
Sounds too good to be true, huh? Well, you are
right. It is too good to be true. Much of the
time, you lose the entire outlay. Options have
a time limit. Most options expire worthless.
5What is the Rational for Options?
- Instead of buying a stock, buy an option to buy a
stock (or an option to sell a stock) - If the stock goes up, your option will go up
(almost always much, much faster) and you can
sell the option for a handsome profit - There is only one catch The option expires in
three, six or nine months - If the stock does not go up, the option is
worthless - Most options expire worthless (Surprise!)
- There are some scenarios where options can be
worthwhile but they are few and far between!
6Option Contracts Example
- Stock currently selling for 20
- You buy a share of the stock for 20
- If it goes up to 30, you have earned 10 on a
20 investment - You buy an option to purchase a share of the
stock at 20 currently selling at 20 - It might only cost you 1 for the option
- If the stock goes up to 30, your option price
will probably go up to around 11 - You have earned 10 on a 1 investment
- That is leverage in action
- Congratulations! Pat yourself on the back!
7Option Contracts Example
(continued)
- But what if the stock price stays at 20
- Your option expires worthless at the end of
three, six, or nine months - And, of course, after your option expires, the
stock price zooms to 40 - You were so sure that this stock was going to hit
the big time and you were absolutely right - But because you bought an option that expired,
you lost the ability to share in the success of
the stock
My advice? Forget about the option and just buy
the stock! But since this is an Intro to
Investments class, we need to become proficient
in the concepts, terms, and techniques of
options. So
8Two Main Types of Options
- Call Option Contract a.k.a. Call
- A negotiable instrument that gives the buyer of
the option the right to buy the underlying
security at a stated price within a certain
period of time - (The previous example was a call option)
- When people talk about options, they are usually
talking about call options - Put Option Contract a.k.a. Put
- A negotiable instrument that gives the buyer of
the option the right to sell the underlying
security at a stated price within a certain
period of time - Opposite of a call option
9Two Main Types of Options
(continued)
- Where did the terms call and put come from
and how will I remember which is which? - The term call comes from the idea that when you
buy a call option, you get the right to call the
stock away from the seller of the option - The term put comes from the idea that when you
buy a put option, you get the right to put the
stock to the seller of the option
Get the idea? A call allows you to call away
the stock from someone (buy it from them). A
put allows you to put the stock to someone
(sell it to them). Let us look at each in
detail.
10The Two Parties of a Call Option
- Buyer of the call option contract
- The Call Option Buyer of the contract is the
person who will do the calling away - They buy the right to call the stock away from
(buy it from) the call seller - They do not have to exercise the right
- In fact, often the options contract expires
worthless - Seller of the call option contract
- a.k.a. Option writer, Option maker
- The Call Option Seller of the contract is the
person who must sell the stock (called away
from) - The call option seller is legally bound to sell
the stock to the call buyer - In return, they get the option price from the
call option buyer
11The Two Parties of a Call Option
(continued)
- What is the Call Option Buyer Hoping For?
- The call option buyer is hoping that the price of
the stock will go up a call option buyer is
bullish - If an option buyer has a call option to buy at
20 and the price goes to 30, the buyer can buy
a 30 stock for only 20 - What is the Call Option Seller Hoping For?
- The call option seller is hoping that the price
of the stock will go down or stay the same a
call option seller is bearish (or at least not
very bullish) - If the stock stays around 20 or goes down, the
call option buyer will not want to exercise the
option and it will expire worthless - And the call option seller gets to keep the price
of the option
12Call Option Example

Ted

Call option buyer
Call option seller
Call Option Contract
The call option buyer wants the price of the
underlying stock to go up. He is bullish. No
matter what happens to the price of the stock, he
can buy it from (call it away from) the call
option seller for 20.
The call option seller wants the price of the
underlying stock to go down. He is bearish. No
matter what happens to the price of the stock, he
must sell it to (called away from) the call
option buyer for 20 if exercised.
The call option contract is tied to the
underlying stock. It will vary up down as the
stock varies.
13The Two Parties of a Put Option
- Buyer of the put options contract
- The Put Option Buyer of the contract is the
person who will do the putting to - They buy the right to put the stock to (sell it
to) the put option seller - Again, they do not have to exercise this right
- Recall Often the options contract expires
worthless - Seller of the put options contract
- a.k.a. Option writer, Option maker
- The Put Option Seller of the contract is the
person who must buy the stock (put to) - The put option seller is legally bound to buy the
stock from the put option buyer - In return, they get the option price from the put
option buyer
14The Two Parties of a Put Option
(continued)
- What is the Put Option Buyer Hoping For?
- The put option buyer is hoping that the price of
the stock will go down a put option buyer is
bearish - If an option buyer has a put option to sell at
20 and the price goes to 10, the buyer can sell
the 10 stock (put it to the option seller) for
20 - What is the Put Option Seller Hoping For?
- The put option seller is hoping that the price of
the stock will go up or stay the same a put
option seller is bullish (or at least not very
bearish) - If the stock stays around 20 or goes up, the put
option buyer will not want to exercise the option
and it will expire worthless - And the put option seller gets to keep the price
of the option
15Put Option Example

Fred

Put option buyer
Put option seller
Put Option Contract
The put option buyer wants the price of the
underlying stock to go down. He is bearish. No
matter what happens to the price of the stock, he
can sell it to (put it to) the put option
seller for 20.
The put option seller wants the price of the
underlying stock to go up. He is bullish. No
matter what happens to the price of the stock, he
must buy it from (put to) the put option buyer
for 20 if the option is exercised.
The put option contract is tied to the underlying
stock. It will vary up down as the stock
varies.
16Time for Questions on Options
- Options are confusing, arent they?
- In fact, the section on options is one of the
hardest parts of the Series 7 Stockbroker exam - Options sound like gambling. I am right?
- Yes. Options are a form of gambling. It is a
zero-sum game. Someone wins, someone loses. - A family acquaintance once called me. Hey,
Frank. I hear you can make a lot of money
investing in options! - I said, Wait a minute. Yes, you can make a lot
of money you can also lose a lot of money. But
you cant invest in options. You can speculate
in options. You can not invest in something that
has a 60 chance of being worthless in three
months! That is not investing.
17Option Attributes
- Strike Price a.k.a. Exercise Price
- The contract price between the buyer of an option
and the seller of the option - The stated price at which you can buy a security
with a call option or sell a security with a put
option - Listed options traditionally sold in
- 2.50 increments for stocks selling for less than
25 - 5.00 increments for stocks selling between 25
200 - 10.00 increments for stocks selling for greater
than 200 - But pricing is more flexible now
- There are some stock options that sell in 1
increments
18Option Attributes
(continued)
- Expiration Date
- The date at which an option expires
- Listed options always expire at the close of the
market on the third Friday of the month of the
options expiration - The hour before close of the market on the third
Friday is sometimes called the witching hour
As well as stock options, there are also stock
index options and stock index futures which we
will discuss later. When all three stock
options, stock index options, and stock futures
expire on the same day, then it is called the
triple-witching hour.
19Option Attributes
(continued)
- Exercise Style
- American options
- Can be exercised at any time before the
expiration - European options
- Can only be exercised at expiration
Normally, if you wanted to take a profit from an
option that had done well and there was still
significant time until the expiration date, you
would simply resell the option instead of
actually exercising the option. However, with an
American-style option, if you really wanted the
stock, you could exercise the option and buy (or
sell) the stock before the expiration date. By
the way, there are several other types of options
with various provisions.
20Quotations of Listed Options
- Go online to finance.yahoo.com
- Choose Investing Options
- (You could also just enter http//biz.yahoo.com/op
t) - Enter the symbol for the stock under Options
Lookup - (Not in the box next to the button labeled Get
Quotes in the upper portion of the screen) - Or, when you are viewing the quote of a stock,
you could simply choose the Options link on the
left hand side of the screen
The list of available options contracts and their
prices for a particular security is called an
option chain.
21Options Contracts
- Buying Selling (writing, making) Options
Contracts - We have discussed options contracts as if they
were traded just as stocks are traded - In most ways, they are very similar
- But there is one major difference
- Options are sold as contracts
- Each contract represents one hundred shares of
underlying security - There are no odd-lots on the options exchanges
So if the listed price of the option is 5, then
one contract will cost 500 (5 100 shares).
Two contracts will cost 1,000, etc.
22Options Contracts
(continued)
- Option Premium
- The quoted price the option buyer pays to buy a
listed put or call option - The seller (a.k.a. writer, maker) receives the
premium immediately and gets to keep it whether
or not the option is ever exercised - (Did I mention that most options expire without
being exercised? That most options expire
worthless?)
To make it more confusing, the term premium is
also used in a more precise manner when valuing
options. For this reason, most people always
refer to the price of the option instead of the
premium of the option.
23Valuations of Options
- In-the-money Call Option
- A call option with a strike price less than the
market price of the underlying security - Example Call Strike Price 50
- Market Price 54
- 4 In-the-money
- Out-of-the-money Call Option
- A call option with no real value because the
strike price exceeds the market price of the
stock - Example Call Strike Price 50
- Market Price 47
- 4 Out-of-the-money
24Valuations of Options
(continued)
- In-the-money Put Option
- A put option with a strike price greater than the
market price of the underlying security - Example Put Strike Price 50
- Market Price 46
- 4 In-the-money
- Out-of-the-money Put Option
- A put option with no real value because the
market price exceeds the strike price of the
stock - Example Put Strike Price 50
- Market Price 52
- 2 Out-of-the-money
25Valuations of Options Example
Call Option
- Call Option Example (Strike price 50, Option
price 10)
Theoretically, for every 1 above the strike
price, the call buyer earns a dollar and the call
seller (a.k.a. call writer) loses a 1.
26Valuations of Options Example
Call Option
(continued)
- Call Option Example (Strike price 50, Option
price 10)
But the previous graph ignored the price of the
option. The call buyer had to pay 10 and the
call seller received 10.
27Valuations of Options Example
Put Option
(continued)
- Put Option Example (Strike price 50, Option
price 10)
Again, theoretically, for every 1 below the
strike price, the put buyer earns a dollar and
the put seller (a.k.a. put writer) loses a 1.
28Valuations of Options Example
Put Option
(continued)
- Put Option Example (Strike price 50, Option
price 10)
But again, the previous graph ignored the fact
the put buyer had to pay 10 for the option and
the put seller (a.k.a. put writer) earned 10.
29Valuations of Options
(continued)
- Time Premium
- The amount by which the option price exceeds the
options in-the-money value - In general, the longer the time to expiration,
the greater the size of the time premium - If an option is out-of-the-money, then the
entire price of the option is due to the time
premium
In other words, an option that is in-the-money
will sell for more than the amount it is
in-the-money because of the time remaining
until the expiration date. Often, an option that
is out- of-the-money will still have time
value. The option still has time to become worth
more (as the underlying stock price changes).
30Commissions on Option Contracts
- And Do Not Forget Commissions!
- In the previous examples, we did not include the
cost of the commissions - A commission is charged whenever an option is
bought or sold - Both buyer and seller pay a commission
- And a commission is charged when and if the buyer
exercises the option and buys or sells the stock - Again, both buyer and seller pay a commission
- When you include the commissions, it makes it
that much harder to make money in options
But if you are a broker, you would simply love to
have your clients get hooked on options. P.S.
None of my clients trade options. I would do my
best to talk them out of it if they asked to!
31Option Strategies
- Speculating You will often hear
- If you feel the market price of a particular
stock is going to move up - If you anticipate a drop in price within the
next six months - It is a highly risky investment strategy, but it
may be suited for the more speculatively
inclined.
The flaw in these arguments is this There has
never been a successful method to predict stock
prices in the short term. You may feel or
anticipate that the price will go up or down,
but that does not mean that it will. It is not
investing, it is gambling. Plus, you may be
correct but your option may expire before you are
proven correct.
32Option Strategies
(continued)
- Hedging
- A transaction or series of transactions made to
reduce the risk of adverse price movements in an
asset - Hedging can be thought of as insurance
- And although insurance can be useful in some
circumstances, it is not free - You pay for the insurance via the price of the
option and the commissions
Investors can use hedging strategies when they
are unsure of what the market will do. A perfect
hedge reduces your risk to nothing (except for
the cost of the option and the commissions).
33Option Strategies
(continued)
- Hedging Example
- You own 100 shares of Butterfly.com and it is
currently selling for 50 - You are afraid the price will plummet within the
next 3 months to 10 - You purchase a put at 50
- No matter what happens, you can sell the stock
for 50 but only until the option expires - Then you must go out and buy more insurance
- This is called a protective put
Insurance is not free. Using options as
insurance is one way to keep your broker very
happy. If you are sure the stock will fall, why
not just sell the darned thing?
34Option Strategies
(continued)
- Straddle
- The simultaneous purchase (or sale) of a put and
a call on the same underlying financial asset - If the price is volatile in either direction, up
or down, you will make money (providing you pass
the break-even point for both purchases plus the
commissions) - If the stock price is not volatile, you would
sell (a.k.a. write, make) the straddle and hope
that the price does not change greatly
Two commissions at the same time! Your broker is
gonna really love you!
35Option Strategies
(continued)
- Straddle Example
- Butterfly.com is selling for 50 but its price is
extremely volatile - You purchase a call for 50 and a put for 50
- The price of the call option is 4 and the price
of the put option is 5 - Now, no matter which way the price goes, one of
your options will be in-the-money
But the call cost you 4 and the put cost you 5,
so the price has to move at least 9 either way
before you break-even. And we did not include
the cost of the commissions. You paid two
commissions for the straddle and possibly one
more for exercising the option. Brilliant
strategy, huh? Wait, it gets better.
36Option Strategies
(continued)
- Spread
- The simultaneous purchase and/or sale of two or
more options with different strike prices and/or
expiration dates - Example Stock selling for 50
- Buy a call at a strike price of 50
- Sell a call at a strike price of 55
- You paid for the call at 50, you got paid for
the call at 55 - If the stock price rises, you make money
The possibilities are endless. And so are the
commissions.
37Option Strategies
(continued)
- Selling Options a.k.a. Writing Options, Making
Options - Selling options allows the individual investor to
play the part of the casino - You become the Las Vegas casino and the option
buyers are betting against you - More often than not, the option writer is
right. - Most options expire worthless
- Have I mentioned this yet?
- No matter what happens, the option seller gets
the buyers premium the price of the option
If and when I ever begin trading options, it will
be as an option writer. But that does not mean
you still can not lose big.
38Option Strategies
(continued)
- Selling Options (continued)
- Covered Options
- Options written against stock owned (or sold
short) by the writer - Naked Options a.k.a. Uncovered Options
- Options written on securities not owned (or sold
short) by the writer
The amount of return to the option writer is
always limited to the amount of option premium
received. But the loss can be substantial, even
unlimited in the case of a naked call, a.k.a.
uncovered call.
39Option Strategies
(continued)
- Selling Options (continued)
- Covered Call
- You own a stock and you are considering selling
- You write a covered call and receive the premium
- If the stock price jumps substantially, the stock
will be called away from you (You will be forced
to sell) - If the stock price stays the same or goes down,
the option will expire worthless - And you can then write another covered call
- In either case, you get to keep the premium
This strategy is only one of two option
strategies I personally would ever consider.
40Option Strategies
(continued)
- Selling Options (continued)
- Covered Call Example
- You own Butterfly.com and it is currently selling
for 50 a share You bought it at 40 and want
to sell - You write a covered call at 55 and receive 500
since the premium for a 55 call is currently 5 - If the stock price jumps over 55, it will be
called away from you at 55 - It is as if you actually sold it for 60 ( 55
5 ) - If the stock prices stays below 55, you can
write another covered call
This strategy allows you to make extra money from
a stock that you already own. Do you see any
disadvantages?
41Option Strategies
(continued)
- Selling Options (continued)
- Naked Put
- You are considering purchasing a stock and you
have the cash to make the transaction - You write a naked put and receive the premium
- If the stock price falls substantially, the stock
will be put to you (you will have to purchase it) - If the stock price stays the same or goes up, the
option will expire worthless - And you can then write another naked put
- In either case, you get to keep the premium
This is the only other option strategy that I
would personally consider.
42Option Strategies
(continued)
- Selling Options (continued)
- Naked Put Example
- You are considering purchasing Butterfly.com and
it is currently selling for 50 and you have the
cash - You write a naked put at 45 and receive a 300
premium since the cost of a 45 put is currently
3 - If the stock price falls below 45, the stock
will be put to you at 45 - It is as if you bought it at 42 ( 45 - 3 )
- If the stock price stays the same or goes up, you
can write another naked put
This strategy allows you to make extra money from
a stock that you want to purchase. Do you see
any disadvantages?
43Employee Stock Options
- Employee Stock Options (a.k.a. ESOs)
- An option granted to an employee by a company
giving the employee the right to buy shares of
stock in the company at a fixed price for a fixed
time - Usually have some significant differences from
normal call options - Cannot be sold
- Expire in many years (up to 10 years)
- Usually have a vesting period (typically 3 to 7
years) - If you leave before the vesting period is over,
you lose your stock options
During the tech boom of the late 1990s, ESOs
were used extensively to attract employees to
start-up companies.
44Employee Stock Options
(continued)
- Employee Stock Options (a.k.a. ESOs)
- During the 2000-2002 bear market, ESOs were the
subject of much controversy - There is still some fall-out and publicity as
companies and the SEC continue to wrangle over
how and even if they should be used - Currently, companies can give ESOs to their
employees and not have to pay anything - They do not reduce the companys earnings
- Many companies have agreed to expense stock
options - Unfortunately, how do you come up with a price
for something that is currently worthless?
45Employee Stock Options
(continued)
- Employee Stock Options (a.k.a. ESOs)
- To make matters worse, while some people became
fabulously wealthy through ESOs during the
Internet mania, - Example John Moores of Padres Peregrine fame
- Many other people were socked with crippling tax
burdens on worthless pieces of paper when their
companies collapsed! - How can that be, you ask?
- The AMT (Alternative Minimum Tax) does not care
if you never exercise the options - You still owe the tax on the paper gain
- Even if you never were able to realize the gain
Bizarre!
46Valuations of Options Revisited
- Wait a minute. Did you ask, How do you come up
with a price for something that is currently
worthless? - Yes, that is correct. Since many ESOs are
out-of-the-money, often by a large amount, or
can not be exercised for a long time, or both,
how does the company put a price on it? - The financial world currently uses a system
called the Black-Shoales Option Pricing Model - It may sound impressive, but it is really very
silly - In my humble opinion
Chapter 16 is devoted to the Black-Shoales model.
We are going to ignore it, if you do not mind.
47Valuations of Options Revisited
- Example The Black-Shoales Option Pricing Model
- Stock currently selling for 7.50 per share
- Employee stock option has an exercise price of
10 - It is currently out-of-the-money
- Plus the option can not be exercised for 3 years
- The Black-Shoales model might say that the
employee stock option is worth 2.50
Huh? You can not sell it. You can not exercise
it for 3 years. It is out-of-the-money. How
is it worth 2.50? The stock price might never
go over 10. And if you are unfortunate enough
to be affected by the AMT, you might have to pay
taxes on it!
48Stock-Index Options
- A put or call option written on a specific stock
market index, such as the SP 500 - A stock-index option allows an investor to
purchase or sell an option that responds to a
stock market index - Can hedge a portfolio by purchasing a put on a
stock-index option that represents the portfolio - Acts as insurance against a large loss (until it
expires) - Over 75 indices represented
- Large, mid, small cap stocks
- Domestic, international, regional,
country-specific
Whether speculating or hedging, it is still risky
and expensive.
49Other Types of Options
- Interest Rate Options
- Put and call options written on fixed-income
securities such as bonds - Currency Options
- Put and call options written on foreign
currencies - Can be an important tool for foreign investors
and multi-national corporations who must
periodically convert U. S. Dollars to and from
other currencies - LEAPS
- Long-term Equity Anticipation Securities
- Long-term options 9 months to 3 years (?)
50Warrants
- A long-lived option that gives the holder the
right to buy stock in a company at a price
specified on the warrant - Warrants are usually issued by the same company
that issues the underlying stock - Often as accompanying securities to bonds
- Or as compensation to employees (like ESOs)
- Unlike options where each contract represents 100
shares of stock, one warrant represents the right
to buy one share of stock - Warrants are always call options
- There are no put warrants
51Final Comments on Options?
The possibilities are endless, and so are the
commissions. (Wait! Lets hear what Optionetics
has to say about options!)
