OPTIONS
Uses
of Derivatives:
1.
Risk Management:
Instead
of wheat, imagine that your
crop is equity securities: You
want their value to
grow
and
generate capital gains. Your
focus is more on investor demand
than on supply. When
the
country goes on the
stock-buying binge, prices go up.
When people get cold feet
and
retreat
from the market, prices go
down. This market risk
phenomenon is generally
analogous
to the farmer's price risk.
Similarly, someone holding bonds
faces a potential for
a
paper loss should interest
rates unexpectedly. Derivative
assets, especially interest
rate
futures,
can be used to reduce the interest rate
risk.
2.
Risk Transfer:
Derivatives
are much more convenient
(and less expensive) to use
than security
purchases
or
sales each time the
portfolio manger decides to
alter market exposure.
Futures and
options
provide a means for risk to
be transferred from one person to some
other market
participant
who, for a price is willing
to bear it.
3.
Financial Leverage:
Derivatives
may provide financial
leverage, which is one of the
primary reasons some
speculators
use them. As an example, an
investor may feel that
Ionics, Inc. (ION, NYSE),
a
manufacturer
of water treatment products, is an
excellent take over candidate. If
that
investor
bought 100 shares of this
stock at $29, the cost would
be $2,900. As an alternative
the
investor could speculate on takeover
rumors using a single stock
option selling for
perhaps
$300. With this position,
the investor would benefit
from a sharp increase in
the
stock
price, but would have
only a modest amount of money at
risk. The worst that
could
happen is
that the investor would lose
all $300. On the other
hand, an investor who
bought
the
stock could lose much more
than that if the stock
plummeted.
4.
Income Generation:
Some
people use derivatives as a means of
generating additional income
from their
investment
portfolio. Options are
widely used for this purpose
in the portfolios of
endowment
funds, pension funds, and
individual portfolios.
5.
Financial Engineering:
Just as
the chemist mixes compounds
in the laboratory to produce
something with known
characteristics,
a financial engineer can mix
financial assets in such a
way that portfolio
has
special
characteristics. Derivative assets
are the basic building
blocks the engineer
uses.
Some
of the recent financial
disasters involving derivatives
occurred because the
product
mix
was the potentially volatile.
Nitroglycerin can be use to treat
heart disease, but
masked
men
of the Wild west also used
it to blow up trains. Slight
variations in the composition
of
portfolio
can result in drastically different
characteristics.

What's
next?
It is
unlikely that we have seen
the last of innovation in
the derivative assets
markets. Many
brilliant
minds are searching for a
better mousetrap in the areas of
risk management and
income
generation. As with much of
scientific discovery, what is
commonplace today
would
have been a marvel just a
few years ago. One thing
that is certain is that
these
products
are the permanent features
of the financial landscape. An informed
investment
professional
needs a basic understanding of
their uses and potential
risks.
The
Origin of an Option:
Two
parties are necessary to trade; if
someone buys an option,
someone else has to sell
it.
Unlike
more familiar securities
such as shares of stock,
there is no set number of
put or call
options.
In fact, the number in
existence changes every day.
Options can be destroyed.
This
unusual
fact is crucial to understanding
the options market.
The
first someone makes in a
particular is called an opening
transaction. When the option
is
subsequently
closed out with a second trade
(or with expiration of the
option), this latter
trade is
called a closing transaction.
Purchases and sales can be either
type of transaction.
Buying
something as an opening transaction is
perhaps easier to understand
than selling
something
as an opening transaction. Returning to
the football ticket example,
the university
created
the tickets and sold them;
this was an opening transaction
for the university.
When
an
option is sold as an opening
transaction, it is called writing an
option.
No
matter what the owner of an
option does, the writer of
the option keeps the
option
premium.
The university keeps the $
24 you paid for the two
tickets whether you go
the
game
or not.
Options
have an important characteristic
called fungibility, meaning
that, for a given
company,
all options of the same
type with the same
expiration and striking prince
are
identical.
Just as a $1 bill is equivalent to any
other $ bill, a Microsoft
APR 90 call written
today
is equivalent to a Microsoft APR 90
call written last month.
Fungibility is particularly
important
to the option writer. An
investor who writes an
option receives premium for
doing
so.
If market conditions changes a
week later, the investor can
buy an identical option
and
close
out the position. The
investor pays for the option
purchased, which may be more
or
less
than the amount received
when the investor wrote
the option. The important
point is
that
the option need not be
repurchased from the specific person to
whom it was sold,
because
the options are
fungible.
THE
OPTIONS MARKET:
Options:
Which
represent claims on an underlying common
stock, are created by
investors and sold
to
other investors? The
corporation whose common
stock underlies these claims
has no
direct
interest in the transaction,
being in no way responsible
for the creating,
terminating,
or
executing put and call
contracts.
Contracts
giving the owner the Tight to buy or sell the
underlying asset
245
Investment

Call:
An option to
buy a stock at a sated price
within a specified period of
months
A
call option gives the
holder the right to buy
(or "call away") 100 shares
of a particular
common
stock at a specified price
any time prior to a
specified expiration date.
Investors
purchase
calls if they expect the
stock price to rise, because
(lie price of the call and
the
common
stock will move together.
Therefore, calls permit
investors to speculate on a rise in
the
price of the underlying
common stock without buying
the stock itself.
Put:
An option to
sell a stock at a stated
price within a specified
period of months
A put
option gives the buyer
the right to sell (or
"put away") 100 shares of a
particular
common
stock at a specified price
prior to a specified expiration
date. If exercised, the
shares
are sold by the owner
(buyer) of the put contract
to a writer (seller) of this
contract
who
has been designated to take
delivery of the shares and
pay the specified price.
Investors
purchase
puts if they expect the
stock price to foil, because
the value of the put will
rise as
the
stock price declines.
Therefore, puts allow
investors to speculate on * decline in
the
stock
price without selling the
common stock short.
Why
Options Market?
An
investor can always purchase shares of
common stock if he or she is
bullish about the
company's
prospects or sell short if bearish. Why
then should we create these
indirect
claims
on a stock as an alternative way to
invest? Several reasons have
been advanced, in-
cluding
the following:
1. Puts and
call expand the opportunity
set available to investors,
making available
risk-return
combinations that would
otherwise be impossible or that
improve the-
risk-return
characteristics of a portfolio. For
example, an investor can;
sell the stock
short
and buy a call, thereby
decreasing the risk on the
short sale for the
life of the
call.
2. In
the case of calls, an
investor can control (for a
short period) a claim on
the
underlying
common stock for a much
smaller investment than
required to buy the
stock
itself. In the case of puts,
an investor can duplicate a short
sate without a
margin
account and at a modest cost in relation to
the value of the stock.
The buyer's
maximum
loss is known in advance. If an option
expires worthless, the most
the
buyer
can lose is the cost (price) of the
option.
3.
Options provide leverage
magnified percentage gains in relation to
buying the stock;
furthermore,
options can provide greater leverage
than fully margined,
stock
transactions.
4.
Using options on a market
index such as the Standard &
Poor's 500 Composite
Index
(S&P 500), an investor can
participate in market movements
with a, single
trading
decision.
Understanding
Options:
To
understand puts and calls, one
must understand the
terminology used in
connection
with
them. Our discussion here applies
specifically to options on the
organized exchanges
as
reported daily in such
sources as The Wall Street
Journal.4
Important
options terms
246
Investment
Analysis & Portfolio Management
(FIN630)
VU
include
the following:
1.
Exercise (strike)
price:
The
exercise (strike) price is the per-share
price at which the common
stock may be
purchased
(in the case of a call) or
sold to a writer (in the
case of a put). Most stocks in
the
options
market have options
available at several different exercise
prices, thereby providing
investors
with a Choice. For stocks
with prices greater than $25,
the strike price changes
in
increments
of $5, whereas for those under
$25, the increment is $2.50.
As the stock price
changes,
options with new exercise prices
are added.
2.
Expiration date:
The
expiration date is the last
date at which an option can be exercised.
All puts and calls
are
designated by the month of
expiration. The options exchanges
currently offer
sequential
options
and-other shorter term
patterns. The expiration
dates for options contracts
vary from
stock
to stock but do not exceed
nine months.
3.
Option premium:
The
option premium is the price
paid by. the option buyer to
the writer (seller) of the
option
whether
put or call. The premium is
stated on a per-share basis for
options on organized
exchanges;
and since the standard contract is for
100 snares, a $3 premium represents
$300,
a $15
premium represents $1500, and so
forth. Information on options
premiums can be
found
on The Wall Street Journal's
"Listed Options Quotation"
page. The most
active
contracts
for the day are
reported along, with some
individual equity options.
Information
about
index options is also available on
this page.
The
options page of The Wall
Street Journal, as well as other sources,
also carries the
information
for long-term options known
as long-term equity anticipation
securities
(LEAPS),
which were introduced in
1990. These long-term options,
available on roughly
450 stocks and
several indexes, trade on four
U.S. exchanges. All LEAPS options
for
stocks
expire in January, and for
indexes, December. Maturities extend
out to about two
and
one-half years.
LEAPS
are typically more expensive
than short-term options, but
with a longer
maturity,
they
may cost less per share when
calculated on a daily basis.
Like short-term options,
they
can be
used to hedge-or speculate.
Standardized
Options Characteristics:
Features:
All
options have standardized expiration
dates. For most options, it
falls on the Saturday
following
the third Friday designated
months. Individual investors
typically view the
third
Friday
of the month as the
expiration date, because exchanges
are closed to public
trading
on
Saturday.
Striking
prices are established at multiples of 2 ˝ or $5
depending on the current
stock
price.
Stocks priced at $25 or below have
the low multiple, while
higher period stocks
have
the
$5 multiple. Shifts in the
price of a stock result in
the creation of new striking
prices. As
a
matter of policy there is
always at least one striking price above
and at least below the
current
stock price.

Both
puts and calls are based on
100 shares of the underlying
security. As investor
who
buys
a call option on the stock
of particular company is purchasing
the right to buy 100
shares
of stick. It is not possible to buy or
sell odd lots of
options.
The
Premium:
The
premium has two components:
intrinsic value and time
value. For a call
option,
intrinsic
value equals stock price
minus striking price; for a
put, intrinsic value
equals
striking
price minus stock price. In
some respects, determining
intrinsic value is the
first
step
in valuing an option. By convention,
intrinsic value cannot be
less than zero.
Time
value
is equal to the option
premium minus the intrinsic
value.
If an
option has no intrinsic
value, it is out-of-the-money, if it does
have intrinsic value, it
is
in-the-money.
In special when an option's striking
price is exactly equal to
the price of
underlying
security, the option is
at-the-money.

How
Options Work:
noted,
a standard call' (put) contract
gives the buyer the
right to purchase (sell) 100
AS
shares
of a particular stock at a specified
exercise price any time
before the expiration
date.
Both
puts and calls are created
by sellers who write a
particular contract. Sellers
(writers)
ate
investors, either individuals or
institutions, who seek to
profit from their beliefs
about
the
underlying stock's likely price
performance, just as the
buyer does.
The
buyer and the seller have
opposite expectations about the
likely performance of
the
underlying
stock, and therefore the
performance of the
option.
1.
The call writer expects the
price of the stock to remain
roughly steady or perhaps
move
down.
2.
The call buyer expects the
price of the stock to move
upward relatively
soon.
3.
The put writer expects the
price of the stock to remain
roughly steady or perhaps
move
up.
4.
The put buyer expects the
price of the stock to move
down relatively soon.
THE
MECHANICS OF TRADING:
The
Options Exchanges:
Five
option exchanges constitute the
secondary market: the
Chicago Board Options
Exchange
(CBOE), the American, the
Philadelphia, the Pacific, and
the newer
International
Securities
Exchange (1SE) in New York.
Traditionally, the first
four exchanges controlled
the
trading of U.S. options,
each handling different
options and competing very
little. The
ISE
began trading in May 2000,
and now has a substantial
share of U.S. trading volume
in
options.
This all-electronic market is
extremely efficient, and has
forced the other
four
exchanges to
handle all options. This
competition has led to lower
costs and narrower
spreads
for customers, and quicker
access to the market.

The
options markets provide
liquidity to investors, which is a
very important
requirement
for
successful trading. Investors
know that they can instruct
their broker to buy or
sell
whenever
they desire at a price set
by the forces of supply and demand. These
exchanges
have
made puts and call a success
by standardizing the exercise date and
exercise price of
contracts.
The
Clearing Corporation:
The
options clearing corporation
(OCC) performs a number of
important functions
that
contribute
to the success of the
secondary market for
options. H functions as an
intermediary
between the brokers
representing the buyers and
the writers. That is, once
the
brokers
representing the buyer and
the seller negotiate the
price on the floor of
the
exchange,
they no longer deal with
each other but with
the OCC.
Through
their brokers, call writers
contract with the OCC
itself to deliver shares
of
the
particular stock, and buyers of
calls actually receive the
right to purchase the
shares
from
the 0CC Thus, the OCC
becomes the buyer for
every seller and the seller
for every
buyer,
guaranteeing that all
contract obligations will be met.
This prevents the
problems
that
could occur as buyers
attempted to force writers to
honor their obligations. The
net
position
of the OCC is zero, because
the number of contracts purchased
must equal the
number
sold.
Investors
wishing to exercise their options
inform their brokers, who in
turn inform the
OCC
of the exercise. The OCC
randomly selects a broker on
whom it holds the
same
written
contract, and the broker
randomly selects a customer
who has written these
options
to
honor the contract. Writers
chosen, in this manner are
said to be assigned an obligation
or
to
have received an assignment notice.
Once assigned, the writer
cannot execute an
offsetting
transaction to eliminate the
obligation; .that is, a call
writer who receives an
assignment
must sell the underlying
securities, and a put writer
must purchase them.
One
of the great advantages of a
clearinghouse is that transactors in
this market can
easily
cancel
their positions prior to
assignment. Since the OCC
maintains all the positions
for
both
buyers and sellers, it can cancel
out the obligations of both
call and put writers
wishing
to
terminate their position.
With regard to puts and calls,
margin refers to the
collateral than
option
writers provide their
brokers to erasure fulfillment of
the contract in case of
exercise.
Options
cannot be purchased on margin. Buyers
must pay 100 percent of the
purchase price.
