Objectives
• Become familiar with options terminology
• Understand the advantages and disadvantages of options
• Recognize when it is profitable to exercise an option.
What is an Option?
• Definition: An option is the rightright, but not the obligation,obligation, to buy or sell a futures contract at some predetermined price at anytime within a specified time period.
• Options are derivative instruments. The option is written on an underlying asset—the futures contract.
Calls and Puts
• A call optioncall option is the right to buy the underlying futures contract at a predetermined price prior to expiration.
• A put optionput option is the right to sell an underlying futures contract at a predetermined price prior to expiration.
Strike Price and Premium
• The predetermined price at which an underlying futures contract may be bought or sold is called the strike pricestrike price or the exercise priceexercise price.
• The premiumpremium is the amount paid for an option. (Paid up-front, no matter what).
Strike Price Listing
When an option is first listed, the strike prices include the closest strike to a futures price and then a predetermined number of then a predetermined number of strikes above and belowstrikes above and below. The number of strikes will vary by exchange.
As market conditions change, additional strikes are listed.
Options – CBOT Example (Jan 19, 2007)
Corn cents/bu
Futures = 390 ¾ Call Put
Strike Price Dec07 Dec07
370 49 29 3/8
380 45 3/8 35
390 41 7/8 41 ¼
400 38 7/8 47 5/8
410 35 7/8 --
420 33 61 ¼
Premiums
• PremiumsPremiums are determined in an open outcry auction. It’s important to realize that all of the options terms are set by the exchange except for the premium.
• The premium is paid up-front by the buyer and must be paid whether the option is exercised or not.
Option Alternatives• The buyer of the option may do the following prior to
the option expiration:
– exercise the option (get the futures position) – offset or liquidate the position
• Buy a put ---sell same put
• Buy a call---sell same call
– allow the option to expire.
No obligation with an option purchase!
When Is an Option Exercised?
• Options can be exercised if profitable.– a put option is profitable when the option strike
is above the underlying futures price (the right to sell higher than the current futures price)
– a call option is profitable when the strike price is below the underlying futures price (the right to buyer below the current market)
What About the Sellers of Options?
• Option Seller (Writer): – receives the premium from the option buyer, and– must take the opposite position if the option is
exercised.
As a result, – the option seller must post margin, and– may face margin calls.
Option Jargon
• In-the-moneyIn-the-money: An option is said to be in-the-money if it is profitable to exercise.
• Out-of-the-moneyOut-of-the-money: An option is said to be out-of-the-money if a loss would result if it were exercised.
• At-the-moneyAt-the-money: An option is at-the-money if its strike price is the same as its underlying futures price.
What Determines an Options Value?
1. Intrinsic Value: the positive value if an option were to be exercised
– Put: Strike Price is Above the Current Futures – Call: Strike price is below the current Futures
2. Days to Expiration
-Value increases as time to expiration increases
What Determines an Options Value?
3. Volatility of Underlying Futures
• Higher volatility increases option premiums
4. Interest Rates
• Higher interest rates lower option premiums
BioFuels Era Impact on Options Value
• With the increase in biofuels demand for corn and uncertainty about supply, volatility of futures has increased!– Average volatility from 1980-2006: 18.3%– Average volatility in 2005: 21.9%– Average volatility in 2006: 28.8%
• This makes option premiums greater than when prices were lower and less volatile

Objectives
• Understand the mechanics of hedging with options
• Establish the advantages and disadvantages of options hedges
• Complete examples of options hedges
Hedging with Options• A long cash market position can be hedged with
options to provide a minimum (floor) price, but also enable higher prices if subsequent futures prices were to rise ( a floor price but no ceiling).
• Two common strategies:– Buy a put option– Sell cash grain and buy an OTM call option
• “Sell and defend”• Both strategies set a price floor price and also allow
you to gain if futures prices subsequently increase.
Why Options Over Futures?
• Seller’s/Buyer’s RemorseSeller’s/Buyer’s Remorse: Option hedgers can take advantage of favorable price movements.
• Posting and Managing MarginPosting and Managing Margin: Buyers of options do not post margin (although writers do).
Which Month and Strike for You to Buy?
1. Contract Month
Time Frame of the Objective
2. Cost of premium
3. Protection level: What is the tradeoff between the premium and the protection?
-Lower protection---lower costs
-Higher protection---higher costs
4. Outlook – what is likely to happen to the underlying futures price.
-----------Plus some more---------
Also for you to consider
5. Your risk bearing ability
6. Your costs of production
7. Your pricing objectives
8. Your understanding of pricing alternatives
A Soybean Example …
• It’s late Spring and you want to protect against low soybean prices at harvest. What month? What option type?
Which strike do you select?
November futures: $5.75
Put option @ $5.75: 25 cents
Put option @ $5.50: 15 cents
Buy a Put(Strategy #2, p50)
• Goal: Establish a price floor
• Advantage: Establishes a floor price but not a ceiling
• Disadvantage: Premium cost
Example—Buy a Put
• In May, an Indiana corn producer seeks to protect the value of corn sold at harvest.
• Question: What type of option should this producer consider buying? Why? What month?
• Question: What are the advantages of this option hedge over futures hedging?
Example—Buy a Put
• Current Dec07 Futures @ $3.90/bu.
• Premium for $3.80 put is $0.35/bu.
• Expected Basis is $0.20 under.
• What minimum price is established?
Example—Buy a Put
Min. Price = $3.80 - $0.35 - $0.20- $0.02 = 3.23
Minimum Price = Strike Price
- Premium
- Expected Basis- Hedging Costs (Interest/Brokerage Fee)
Example--Put, Prices Fall
At marketing in November, suppose prices fall.Futures Prices @ $3.00
Cash Prices @ $2.80

Strike Price/Premium Tradeoff
• Put:– Higher strike price means more price protection, but it
costs more– Lower strike price costs less, but it means less price
protection
• Call:– Lower strike price means more chance of payoff, but it
costs more– Higher strike price costs less, but means less chance of
payoff (futures price has to increase more to get above the strike price)
Sell Cash and Buy OTM Call(Strategy #5, p. 57)
• Strategy is called a synthetic put because it establishes a price floor and leaves upside potential in place (no ceiling)– Pre-harvest combine a forward contract with
OTM call
– Post-harvest combine cash sale with OTM call
Example—Sell Cash Grain in March and Buy OTM Call (Weather Protection)
• Current July07 Futures on March 1 are $4.25/bu.
• Cash price on March 1 is $4.00. Corn delivered and sold at $4.00.
• Premium for $4.50 July call is $0.28– A $4.50 call is OTM—this option allows the owner to gain if July
futures move above $4.50. Since the current July futures is $4.25, they cannot start gaining until the July futures move up $.25 per bushel. (They can gain after the market moves up $.25/bu.)
• What minimum price is established?
Example—Sell Cash Grain, Buy OTM Call
Min. Price = $4.00 - $0.28- $0.02 = $3.70/bushel
Minimum Price = Cash Price
- Premium- Hedging Costs (Interest/Brokerage Fee)
Example—Cash & Call, Prices Fall
Say by June weather has favorable and July futures drop.
July Futures Prices @ $3.25

Sell a Call(Strategy #3, p. 52)
• Goal: Increase selling price
• Advantage: Receive premium
• Disadvantage: Little price protection and sets maximum price (price ceiling)
Sell a Call
• Current Dec07 Futures @ $3.90/bu.
• Premium for $4.00 call is $0.36/bu.
• Expected Basis is $0.20 under.
• What maximum price is established?
Example—Sell a Call
Max. Price = $4.00 + $0.36 - $0.20- $0.02 = 4.14
Maximum Price = Strike Price
+ Premium

Limited downside protection
Fence (Window): Buy a Put and Sell a Call (Strategy #4, p. 53)
• Goal: Provides both floor price and ceiling price. Locks in cheap price protection
• Advantage: Cost of floor price protection (put) is reduced by income from selling call
• Disadvantage: Limited upward price potential (establishes a ceiling price)
Fence (Window) : Buy a Put and Sell a Call
• Combine previous two strategies with OTM Put and OTM Call
• Current Dec07 Futures @ $3.90/bu.– Premium for $4.20 call is $0.30/bu.– Premium for $3.60 put is $0.26/bu.
• Expected Basis is $0.20 under • What minimum and maximum prices
are established?
Fence or Window• Total premiums = -$0.26+$0.30 = +$0.04
• Buy Put establishes minimum price (price floor)Min Price = Put Strike Price + Total Premium- Expected

Before Hedging with Options…
• Calculate minimum price
– Is this price above loan?
• An LDP is a free put—no need to buy another
• Is this price high enough to cover your costs?
• Is the option strategy the best alternative given all
the pricing alternatives and your farm’s individual
considerations?
Pricing Options Summary1. Do no forward pricing
2. Futures Hedge (lock in the futures price)
3. Options Hedges– Long cash grain and buy Puts (floor price, no ceiling)
– Sell cash grain and buy OTM Calls (floor price, no ceiling) (called a synthetic put)
– Long cash grain and sell Calls (Ceiling price, limited downside protection)
– Long cash grain and Fence by buying Puts and selling Calls (establishes a floor and ceiling price at a low costs)
