Put Option Basics
Research for Online Investors

What does it mean to buy a
“Put”?
A “Put” is an option contract
that gives you the
right to sell the
underlying stock at a predetermined price on a certain
date.
The writer (seller) of the ‘put’
is obligated to purchase the underlying stock at the strike
price.
Put contracts are the opposite of
‘Call’ contracts. Call contracts are bought when you think the
price of a stock will increase. When you own a ‘call’ contract,
you have the
right to buy a stock at a set
price for a predetermined amount of
time.
The key to these two
instruments is you are in control. You can exercise the contract, or let
it expire.
You have the right to
buy the underlying stock with a ‘call’ (normally
exercised only if the stock moves above the strike
price).
You have the right to
sell the underlying stock with a ‘put’ at the strike
price (normally exercised only if the stock falls below the
strike price).
Put contracts can be used to
‘protect’ a position, or as a tool to capitalize on a stock
going down in price. This is akin to shorting a stock, but buying
a ‘put’ limits your risk to the premium paid for the ‘put’
option.
Think of a ‘Put’ as your option
to put a stock to the
seller.
Let’s say ABC company stock is
trading at a high price and the investor wants to protect
against a possible fall in the price. In this case we don’t want to sell the stock,
but buy protection against a drop in the stock
price.
Put options are like call
options; each option contract is for 100 shares of the
underlying stock but is priced at cost per
share.
A put price at $1.00, means $1
dollar per share and will cost $100.00 (plus commission) when
executed.
Let’s look at an
example: present stock
prices and amount
committed:
ABC stock priced
at:
$50 x 100
shares = $5,000.00
March $49.00 put bought @ $1 x
100 shares = $ 100.00
Total value of stock and cost of
put:
$5,100.00
Third Friday in March
price:
ABC stock priced
at: $45.00 x 100 shares = $4,500.00
March $49.00 put sold @ $ 4.00 x
100 shares
= $ 400.00
ABC stock and put value at end of
period:
= $4,900.00
Loss:
$ 200.00
In this instance our investor
paid $1.00 per share to protect his shares in
ABC.
Rather than suffering a $5.00
loss per share, the put increased in price as the share price
dropped.
The investor can sell his shares
to the seller of the put, or just ‘sell to close’ the put
before close of business on the option expiration
day.
The investor experienced a total
loss of $200 rather than $500 by owning a put on his
shares.
If the investor was wrong, and
ABC Company’s stock increased in price, the put option would
expire worthless. In this case, the investor looks at the ‘put’
as insurance.
Just like your homeowners
insurance, we pay for it just in case we need
it!
You can also buy ‘put’ contracts
to capitalize on a stock price going down, without owning the
underlying stock, rather than shorting the
stock.
Let’s look at the same
example: present stock
prices and amount
committed:
ABC stock sold short at:
$50 x 100
shares = $5,000.00
March $49.00 put bought @ $1 x
100 shares =
$
100.00
Third Friday in March
price:
ABC stock buy to cover at: $45.00
x 100 shares
=$4,500.00
March $49.00 put sold @
$ 4.00 x 100
shares
= $ 400.00
Gain on ABC
short
=
$
500.00
Gain on $49
put:
$400.00 -
$100.00
= $ 300.00
You made a 10% gain on risk
capital in the short transaction, this is more than on the
‘put’ contract, but your potential losses were unlimited,
because the price of ABC stock could have gone higher, much
much higher.
The ‘put’ contract cost $100 and
returned $400 for a $300 gain, a 300% return on risk
capital. You had no
potential losses other than the original $100 purchase price of
the ‘put.’
What is
the largest disadvantage to ‘put’ contracts; time. You
own a contract to sell that is limited by time, and time decay
can eat into your profits quickly. In the example above,
our investor paid $1 to have the right to sell the stock at
$49. If ABC ended the time period at $48.50, you would
make back $0.50 for a loss of $0.50 per share. It doesn’t
matter if the stock goes to $45 per share a week after the
option expires. You can be right in your prediction, but
wrong in time frame and lose money. If you shorted the
stock, you could buy to cover for the $48.50 per share and make
a smaller profit or chose to wait longer for the lower target
price.
Puts and calls may not be bought,
or sold, in IRA or 401K accounts. The exception being
covered calls, such as in our Buy, Sell,
Hold Service. You must sign an
option addendum with your online brokerage company to sell
and buy options.
To buy a
put option we enter the option symbol, it is generally made up
of five letters. You may have to enter a (.) period in
front of the symbol. Enter the quantity of contracts you
want to purchase, remember each contract is for 100
shares. Option contracts trade with a Bid and Ask price,
we highly recommend using limit orders on option contracts as
the ‘spread’ is usually wider on options than on stocks.
We use the ‘Buy to Open’ to place the order. This refers
to ‘Opening’ the contract. If we chose to sell the option
contract before it expires, we would ‘Sell to Close’ to close
the contract.
We have
talked about buying put option contracts; you can also sell put
options. Using the ABC company trading at $50, if we
believed it would increase in price through the option
expiration date, we could sell to open the $49 put for $1.00
per share. If it stays above $49 through option
expiration day we get to keep the $1.00 premium. If ABC
falls under $49 per share we would have to buy the stock at the
$49 Then we
are faced with the decision of holding the stock or selling it
for less than the strike price. This is not a trade you
want to enter lightly, it can be dangerous. Thus it is
called selling a “naked” put.
Selling
puts can be used to acquire stocks at a price lower than
today's market price. If you do your research and decide
you want to own ABC company for a long-term investment, why not
sell (write) puts on it to buy at a cheaper price. You
will be paid to wait in option premium, which further reduces
your cost in ABC if the stock is "put to the
seller".
I hope this has been helpful to
you. If you have experience in options, it may seem
elementary, but remember the first option you bought. We
all have to start somewhere. I encourage you to start by
buying one contract, and monitoring your trade for
experience. Experience is the very best teacher, and will
help you understand the concepts
better.

It really does
become amazing to watch.
We had a "debate"
locally Friday night of Republicans running for the
House.
I could not go as work on the
Long Term Portfolio consumes Friday
night.
A friend emailed Saturday
morning that one of the candidates had a "deer in
headlights" look. And she is the one that is in the
statehouse now! I have seen some of her statements in
the paper and thought "Wow." When you can't do anything thing else;
run for office.
