Chapter 14: Options Markets - Financial Markets and Institutions

Background and Fundamentals of Options

  • Definition of Options     * Call Option: Represents the right to purchase an underlying financial instrument at a specified exercise price (or strike price) within a defined period of time.         * In the money: When the current market price of the underlying instrument is greater than the exercise price (MarketPrice>ExercisePriceMarket Price > Exercise Price).         * At the money: When the market price is exactly equal to the exercise price (MarketPrice=ExercisePriceMarket Price = Exercise Price).         * Out of the money: When the market price is less than the exercise price (MarketPrice<ExercisePriceMarket Price < Exercise Price).     * Put Option: Represents the right to sell an underlying financial instrument at a specified exercise price (or strike price) within a defined period of time.         * In the money: When the market price is less than the exercise price (MarketPrice<ExercisePriceMarket Price < Exercise Price).         * At the money: When the market price equals the exercise price (MarketPrice=ExercisePriceMarket Price = Exercise Price).         * Out of the money: When the market price is greater than the exercise price (MarketPrice>ExercisePriceMarket Price > Exercise Price).

  • Comparison of Options and Futures     * Premiums: To obtain an option, the buyer must pay a premium in addition to the price of the financial instrument itself. In contrast, futures contracts primarily involve obligations without an upfront premium of this nature.     * Expirations: The owner of an option maintains the choice to let the contract expire on the expiration date without exercising it if the transaction is not favorable. Futures contracts typically represent a binding obligation to fulfill the contract terms.

  • Markets Used to Trade Options     * Chicago Board Options Exchange (CBOE): Established in 1973, it remains the most significant exchange for trading options.     * CME Group: Another major venue where options are traded.     * Stock Exchanges: As stock options gained popularity, various stock exchanges began listing them.     * Listing Requirements: A primary requirement for an option to be listed is a minimum trading volume of the underlying company's stock.     * Role of the Options Clearing Corporation (OCC): Serves as the essential guarantor for option contracts traded within the United States to ensure contract fulfillment.     * Regulation: Trading is regulated by the Securities and Exchange Commission (SEC) and other regulatory bodies.

  • Executing Trades     * Types of Orders: Investors can utilize market orders (executed at the prevailing price) or limit orders (executed only at a specific price or better) for option transactions.     * Online Trading: Option contracts can be conveniently purchased or sold through online platforms.

Institutional Participation in Options Markets

  • Commercial Banks: Sometimes offer options directly to business clients.

  • Savings Institutions: Typically take positions in options on futures contracts to hedge against potential interest rate risk.

  • Mutual Funds:     * Stock Mutual Funds: Take positions in stock index options to hedge against declines in the market value of their portfolios. They may also take speculative positions to boost returns.     * Bond Mutual Funds: Use options on futures to hedge against interest rate risk.

  • Securities Firms: Function primarily as brokers, executing stock option transactions on behalf of individuals and businesses.

  • Pension Funds:     * Utilize stock index options to protect their stock portfolios from price declines.     * Use options on futures contracts to hedge bond portfolios against adverse interest rate movements.

  • Insurance Companies:     * Employ stock index options for hedging equity portfolios.     * Use options on futures to protect bond portfolios from interest rate volatility.

Determinants of Stock Option Premiums

  • Determinants of Call Option Premiums     * Market Price: There is a positive relationship; the higher the existing market price relative to the exercise price, the higher the call option premium.     * Stock Volatility: Greater volatility in the underlying stock leads to a higher call option premium because of the increased potential for the price to exceed the strike.     * Time to Maturity: The longer the time until expiration, the higher the premium, as there is more time for price favorable movements.

  • Determinants of Put Option Premiums     * Market Price: There is an inverse relationship; the higher the market price relative to the exercise price, the lower the put option premium.     * Stock Volatility: Similar to calls, greater volatility results in a higher put option premium.     * Time to Maturity: A longer duration until expiration increases the put option premium.

  • Deriving Volatility through Pricing Formulas     * Investors use option-pricing formulas (like Black-Scholes) to estimate a stock's anticipated volatility.     * Implied Volatility: By inputting the prevailing market premium and other known factors into the formula, investors can calculate the implied standard deviation or implied volatility.

  • Indicator Monitoring     * Option traders monitor economic indicators because conditions influence cash flows and firm valuations, which in turn impact premiums.     * Framework factors include economic conditions, market conditions, and anticipated volatility.

Speculating with Stock Options

  • Speculating with Call Options: Used when an investor expects the price of the underlying stock to increase. If the stock price rises above the strike price plus premium, the investor realizes a profit.

  • Speculating with Put Options: Used when an investor expects the price of the underlying stock to decrease.

  • Case Study: Steelco Potential Returns (Exhibit 14.10):     * Option 1 (105105 strike, 1010 premium): Profit per unit ranges from −10-10 (at stock price 104104) to 1111 (at stock price 126126). Percentage return from −100%-100\% to 110%110\%.     * Option 2 (110110 strike, 77 premium): Profit ranges from −7-7 to 99. Percentage return from −100%-100\% to 129%129\%.     * Option 3 (115115 strike, 44 premium): Profit ranges from −4-4 to 77. Percentage return from −100%-100\% to 175%175\%.

  • Managing Speculative Risk:     * Firms must monitor employees to ensure trading stays within internal guidelines.     * Separation of reporting and trading functions is critical so traders cannot hide losses.     * Firms should evaluate positions closely when receiving margin calls.

Hedging Strategies using Options

  • Covered Call Strategy:     * Involves selling a call option on a stock already owned by the investor.     * Downside Protection: The premium received from the call sale partially offsets losses if the stock price declines.     * Upside Limitation: If the stock price increases significantly, the call will be exercised, and the investor must sell the stock at the strike price, capping gains.

  • Hedging with Put Options: Portfolio managers use put options to protect against temporary declines in a stock's value. The put sets a floor on the potential loss.

  • Long-term Equity Anticipations (LEAPs):     * Options with expiration dates ranging from two to three years from their listing date.     * Available for large-capitalization stocks and are more effective for long-term hedging than short-term options.

Options on ETFs and Stock Indexes

  • Overview: Options are available on various exchange-traded funds (ETFs) and major stock indexes, allowing for speculation on broader market movements.

  • Settlement: These provide the right to trade the index at a specified price by the expiration date.

  • Examples of Available Instruments (Exhibit 14.13):     * ETFs: iShares Nasdaq Biotechnology, iShares Russell 1000 Value, Financial Select Sector SPDR, Health Care Select Sector SPDR.     * Indexes: S&P 500, S&P 100, Nasdaq 100, Dow Jones Industrial Average, Russell 2000, Emerging Markets Asia Index.

  • Dynamic Asset Allocation: Managers switch between risky and low-risk positions based on market expectations. Index options are used to adjust market exposure efficiently.

  • Measuring Market Risk: A stock index's implied volatility can be derived from its index options, providing insight into market-wide risk sentiment.

Options on Futures Contracts

  • Definition: Gives the owner the right (but not the obligation) to purchase or sell a specific futures contract at a set price within a set period.

  • Speculation on Interest Rates:     * Decline in Rates: Speculators purchase call options on Treasury bond (T-bond) futures.     * Increase in Rates: Speculators purchase put options on Treasury bond futures.

  • Hedging Interest Rate and Stock Risk:     * Banks hedge mortgage/bond portfolios with interest rate futures options.     * Investors hedge stock portfolios with index futures options to offset potential losses while retaining some upside potential.

  • Exhibit 14.14 Hedging Results (T-Bond Put Options):     * Scenario 1 (Rates Rise): T-bond futures price declines to 91−0091-00. Decision: Exercise put option. Result: Sale at 98,00098,000 minus Purchase at 91,00091,000 minus Premium 2,0002,000 equals Net Gain of 5,0005,000.     * Scenario 2 (Rates Fall): T-bond futures price increases to 104−00104-00. Decision: Do not exercise. Result: Net loss of 2,0002,000 (the premium paid).

Executive Compensation and Globalization

  • Options as Executive Compensation:     * Purpose: To align executive incentives with the firm's stock performance.     * Drawbacks: Programs often ignore general market conditions. Executives may be tempted to manipulate stock prices for short-term gain at the expense of long-term stability.

  • Globalization of Options:     * Currency Options: Provide the right to buy (call) or sell (put) a specific currency at a set price.     * Speculation: Buyers pick calls for strengthening currencies and puts for weakening currencies.     * International Business: Firms use currency options to hedge future payables and receivables in foreign markets. Every buyer requires a seller (writer) to form a contract.
