INTRODUCTION
Dear Reader,
When you finish reading this book you be surprised to see how interesting and the simple the subject
is. However, you might find the terminology difficult, and you will need to study it. But don’t worry, after
looking a few times at the options table in the newspaper and the internet, the terminology will “stick”
and become a part of you.
In order to make the subjects understandable and to aid in their ongoing absorption, we preferred to
leave out details and subjects which are somewhat unusual, some of them marginal and technical and
some of them too complex. Here and there we have strayed from being totally accurate, intentionally
or unintentionally. This is a book for beginners and is not designed to make you into a professional. The
knowledge gained by you will enable you to improve your profitability in the capital market, both as a
saver and as a lender.
The improvement will be expressed in the ability to get the best out of your financial adviser at the bank.
Reader Guidelines
1. In the course of reading the first pages, don’t invest too much thought and effort on subjects or details
about which have not given details or details mentioned briefly, and which remain unclear.
Don’t worry! We have thought of everything. The details will become clear before you reach page 49.
2. Since effort is required to absorb the terminology, we recommend reading the book a few times.
3. The drawings are for illustration and understanding, and are not there for decorative purposes, so don’t
skip them.
4. Changes in trading procedures: In view of the dynamism of the capital market, the stock market
changes to trading procedures from time to time. It is possible that when reading the book the trading
procedures could be different from what appears in it.
5. We use the letter K instead of 000.
For example: $100k is written instead of $100,000.
Each time the letter K is written, read it as thousand.
K – An abbreviation of Kilo (=1000).
We would be happy to hear any reactions and to answer any questions relating to an understanding of
the material.
Enjoyable reading
S. Simanovsky

Introduction
Types of Options
There are two types of options:
1. Call option (= buy option)
2. Put option (= sell option)
Call Options
A call option is a security giving its owner the right to purchase an asset, known as the “underlying asset”
(for example: a house), at a price agreed upon in advance, which is known as the “strike price” (for example:
$100,000).
An option has a limited duration. The option contains a definition of the “underlying asset”, what the
terms of purchase are and the duration of the option. We purchase the “underlying asset” from the “option
writer”, who we talk about later. Buying an option is similar to buying a lottery ticket. You buy, in the
expectation of making a profit. If you do not make a profit, the option becomes “garbage”.

Examples of an Underlying Asset
An underlying asset can be any asset, but the most common assets are standard assets, such as: An ounce
of gold, 1,000 barrels of oil, 100 “Microsoft Corp.” shares etc. There are some intangible assets also, such as
share indexes, which we will deal with in more detail later on.
Underlying Asset in the Example: House
In order to simplify understanding of the subject, we will use an example where the “underlying asset” is
a house at an imaginary vacation resort, where all the houses are of the same size and price. The prices of
the houses change daily according to the number of vacationers at the resort. The more vacationers there
are in town, the greater the price is and likewise, the fewer vacationers in town, the lower the price will be.
Premium
The price we pay for the option is known as the premium. The premium is like the price we pay for a
lottery ticket.
Exercising the Call option
We will exercise the Call option only if we are able to buy the underlying asset at a price lower than the
market price. If this is not possible, we will throw the option in the garbage.
Put Option
A Put option is a security giving us the right to sell an asset, known as the “underlying asset” (for example:
a house), at a price agreed in advance, which is known as the “exercise price”. The option has a limited
duration. The option also contains a definition of the “underlying asset”, what the terms of sale are and
the duration of the option.

Options- Introduction
Exercising the Put Option
We would exercise the Put option only if we are able to sell the underlying asset at a price higher than the
market price. If this cannot be done, we will throw the option away.
Options Trading
Most options are traded in a stock market. This means that the stock market acts as an intermediary
between buyers and sellers of options. The brokerage is carried out in the stock market. The prices of
the options, as we previously stated, are referred to as the “premium”, and they change during trading,
according to the supply and demand, in exactly the same way as the prices of shares vary. At the start of
trading you can buy a particular option for a premium of $10, and sell the option at the end of the trading
day for $20. In this book, we will relate only to traded options and we will assume that the houses in the
example are tradable. In other words, we can buy and sell the options on any day when trading takes
place in the stock market.

Call Option - Characteristics
Every option (both Put and Call) are characterized by four items of data which are known in advance, as
follows:
Illustration 1- Example of Call option data
1. Underlying asset: In our example, the underlying asset is the house in the vacation resort.
2. Type of option: Call.
3. Exercise price: The price which the option holder pays for the house if he decides to exercise the
option. In our example, he would pay $100K for the house. The exercise price is a fixed price, which is
known in advance and is not affected by the market price.
4. Expiry date: Every option has a limited duration. The expiry date stated is the last day of its life and
after that date it becomes worthless. The duration of an option varies from market to market. Usually
its duration is less than one year.
Period of Exercise of the Option
A distinction is made between two methods:
1. The American method - the option can be realized at any time up to the expiry date.
2. The European method - the option can be exercised only at the date of expiry.

Options- Introduction
Put Options - Characteristics
As previously mentioned, a Put option is an option to sell an underlying asset, for example an option
to sell a house. The explanation for the four items of data in the following illustration is similar to the
previous explanation about the call option.
Illustration 2- Example of Put option data
Option name
The name of an option consists of 4 parts, which are its four pieces of data:
1. Underlyin asset
2. Type of option
3. Exercise price
4. date of expiry
The name of the option is shown below and is read from left to right:
Uniformity of data
The data relating to options on the same “underlying asset” are usually uniform. For example, in the case
of houses, the price of the houses is always in thousands of dollars and the expiry is always on the last day
of the month.

Abbreviated name
The uniformity of data enables us to abbreviate the name of the option. The abbreviation is based on the
fact that the person trading in options will recognize the meaning of the abbreviations.
the abbreviated name of the call option will be:
Explanation of abbreviations
H - House.
C - Call.
100 - $100K.
June - June 30, 2008.
The abbreviated name of a Put option will be:
A further abbreviation of the name: If we know for certain that the underlying asset is a house, we can
dispense with the H.
For example: When the options appear in the newspaper under the title “Prices of options on houses”.
The abbreviated name will be:
