Protective puts
Using calls to hedge a short position
Writing covered calls to protect against
market downturns
Options as a Hedge

Hedgers transfer unwanted risk to
speculators who are willing to bear it
–


13
E.g., insuring a home
Insurance that expires without a claim does
not constitute a waste of money
Hedging a stock or commodity price
position - clarity on the objective is
important
Protective Puts

A protective put is a descriptive term given
to a long stock position combined with a
long put position
–
14
Investors may anticipate a decline in the value
of an investment but cannot conveniently sell
the security or choose not to for some reason

The maximum loss is $6.25
The maximum loss occurs at all stock prices of
$75 or below
The put breaks even somewhere between $75
and $90 (it is exactly $81.25)
The maximum gain is unlimited but it will always
be reduced by the cost of the ‘insurance’ - this is
what needs to be clearly understood

Protective Put
Logic:
 A protective put is like an insurance policy
–

You can choose how much protection you want
The put premium is what you pay to
transfer the risk of large losses
–
The striking price puts a lower limit on your
maximum possible loss

–
20
Like the deductible in car insurance
The more protection you want, the higher the
premium you are going to pay

Synthetic Options

The term synthetic option describes a
collection of financial instruments that are
equivalent to an option position
–

look at the shape of the protective put - similar
appearance to a call option position
A protective put is an example of a synthetic call

Using Calls to Hedge A Short
Position


24
Short sale
Microsoft example
Hedging a Short Position
25

Call options can be used to provide a hedge
against losses resulting from rising
security prices

Call options are particularly useful in short
sales
Short Sale

Investors can make a short sale
–
–


26
The opening transaction is a sale
The closing transaction is a purchase
Short sellers borrow shares from their
brokers
Closing out a short position is called
covering the short position
Short Sale (cont’d)


A short sale is like buying a put - you profit
from a decline in the price of the security
Many investors prefer the put
The loss is limited to the option premium
– Buying a put requires less capital than margin
requirements
However:
– The put has a limited life or time frame
– The cost of the put needs to be considered
–



in a long put
–
Assume the purchase of an OCT 90 call at $3.38
in addition to the short sale
–
The potential for unlimited losses is eliminated

Writing Covered Calls to Protect
Against Market Downturns

A call where the investor owns the stock
and writes a call against it is called a
covered call
–
–
33
The call premium cushions the loss
Useful for investors anticipating a drop in the
market but unwilling to sell the shares now

Writing Covered Calls to
Generate Income




36
Actually quite a conservative approach
An attractive way to generate income for
foundations, pension funds, and other
portfolios
A very popular activity with individual
investors
Attractive when investor expects stock to
trade sideways
Writing Calls to Generate
Income (cont’d)

Writing calls may not be appropriate when
–
–
Option premiums are very low
The option is very long-term


37
may be able to generate more income by writing a
series of shorter term call options
give away upside opportunity for long term
Writing Calls to Generate
Income (cont’d)
Writing a Microsoft Call Example
It is now July 10, 2001. A year ago, you bought 300
shares of Microsoft at $46. Your broker suggests
writing three OCT 90 calls @ $3.38, or $338.00 on
100 shares.
38
Writing Calls to Generate
Income (cont’d)
Writing a Microsoft Call Example (cont’d)
If prices advance above the striking price of $90,
your stock will be called away and you must sell it
to the owner of the call option for $90 per share,
despite the current stock price.
If Microsoft trades for $90, you will have made a
good profit, since the stock price has risen
substantially. Additionally, you retain the option
premium.
39
Writing Naked Options


40
A naked option position is one where you do not
have another related security position that can
cushion losses from price movements that are
adversely impacting your short option position
– long stock position cushions losses from a
short call option position - ‘covered call’
– short stock position cushions losses from a
short put option position
Very risky due to the potential for unlimited losses
- no offset or cushion
Writing Naked Calls(cont’d)
Writing a Naked Microsoft Call Example
The following information is available:




41
It is now July 11
A July 95 MSFT call exists with a premium of $.12
The July 95 MSFT call expires on July 21
Microsoft currently trades at $79.44
Writing Naked Calls(cont’d)
Writing a Naked Microsoft Call Example
(cont’d)
A brokerage firm feels it is extremely unlikely that
MSFT stock will rise to $95 per share in ten days.
The firm decides to write 100 July 95 calls. The firm
receives $0.12 x 10,000 = $1,200 now. If the stock
price stays below $95, nothing else happens. If the
stock were to rise dramatically, the firm could
sustain a large loss.
42
Naked vs. Covered Puts
43

A naked put means a short put by itself

A covered put means the combination of a
short put and a short stock position
Naked vs. Covered Puts (cont’d)

A short stock position would cushion (only)
losses from a short put:
Short stock + short put  short call
Profit/
Loss
44
Stock Price
@ Expiration
Naked or Short Put
Long stock + short call =‘s short put
(covered call) =‘s (approx) short put
……a strategy to consider!
45
Put Overwriting:

Put overwriting involves owning shares of stock
and simultaneously writing put options against
these shares
–
–
–
46
Both positions are bullish
Appropriate for a portfolio manager who needs to
generate additional income but does not want to write
calls for fear of opportunity losses in a bull market
Also a consideration in Corporate Share repurchase
(buyback) situations - short put
Microsoft Example

An investor simultaneously:
–
–
47
Buys shares of MSFT at $79.44
Writes an AUG 80 MSFT put for $4

Improving on the Market

Writing calls to improve on the market
–
56
Investors owning stock may be able to increase
the amount they receive from the sale of their
stock by writing deep-in-the-money calls against
their stock position
Writing Calls to Improve on the
Market (cont’d)
Writing Deep-in-the-Money Microsoft Calls Example
Assume an institution holds 10,000 shares of MSFT. The
current market price is $79.44. AUG 60 call options are
available @ $21.
57
The institution could sell the stock outright for a total of
$794,000. Alternatively, the portfolio manager could write 100
AUG 60 calls on MSFT, resulting in total premium of $210,000.
If the calls are exercised on expiration Friday, the institution
would have to sell MSFT stock for a total of $600,000. Thus,
the total received by writing the calls is $810,000, $16,000
more than selling the stock outright.
Writing Calls to Improve on the
Market (cont’d)

There is risk associated with writing deepin-the-money calls
–
–

58
It is possible that Microsoft could fall below the
striking price (option strategy less
advantageous vs outright sale)
Bid/ask and liquidity/depth considerations
Upside is essentially capturing time value
associated with the option
Writing Puts to Improve on the
Market

Writing puts to improve on the market
–

Risks to consider:
–
–

59
An institution could write deep-in-the-money puts when it
wishes to buy stock to reduce the purchase price
If the stock rises above the strike price and the put is not
exercised, the stock has not been acquired
‘opportunity loss’ if the stock price falls ie you would have
done better simply buying the stock outright
Trading range for the stock when this strategy is
advantageous
