Options • What are options? • An option is the right, but not the obligation, to buy or sell an item at a predetermined price within a specific time period. • Options on futures are the right to buy or sell a specific futures contract. • Option buyers pay a price (premium) for the rights contained in the option.
Option Types • Two types of options: Puts and Calls • A put option contains the right to sell a futures contract. • A call option contains the right to buy a futures contract. • Puts and calls are not opposite positions in the same market. They do not offset each other. They are different markets.
Put Option • The Buyer pays the premium and has the right,but not theobligation,to sell a futures contract at the strike price. • The Seller receives the premium and isobligatedtobuy a futures contract at the strike price if the Buyer uses their right.
Call Option • The Buyer pays a premium and has the right, but not theobligation,to buy a futures contract at the strike price. • The Seller receives the premium butis obligatedtosell a futures contract at the strike price if the Buyer uses their right.
Options as Price Insurance • The person wanting price protection (the buyer) pays the option premium. • If damage occurs (price moves in the wrong direction), the buyer is reimbursed for damages. • The seller keeps the premium, but must pay for damages.
Options as Price Insurance • The option buyer has unlimited upside and limited downside risk. • If prices moves in their favor, the option buyer can take full advantage. • If prices moves against them, the option seller compensates them. • The option seller has limited upside and unlimited downside risk. • The seller gets the option premium.
Option Issues and Choices • The option may or may not have value at the end • The right to buy corn futures at $6.00 per bushel has no value if the market is below $6.00. • The buyer can choose to offset, exercise, or let the option expire. • The seller can only offset the option or wait for the buyer to choose.
Strike Prices • The predetermined prices for the trade of the futures in the options • They set the level of price insurance • Range of strike prices determined by the futures exchange
Options Premiums • Determined by trading in the marketplace • Different premiums • For puts and calls • For each contract month • For each strike price • Depends on five variables • Strike price • Price of underlying futures contract • Volatility of underlying futures • Time to maturity • Interest rate
Option References • In-the-money • If the option expired today, it would have value • Put: futures price below strike price • Call: futures price above strike price • At-the-money • Options with strike prices nearest the futures price • Out-of-the-money • If the option expired today, it would have no value • Put: futures price above strike price • Call: futures price below strike price
