Determinants of Stock Option Premiums How Option Pricing Can Be Used to Derive a Stock’s Volatility ■ Some investors assess a specific stock’s risk by using the option-pricing formula to estimate the stock’s anticipated volatility. ■ By using the prevailing option premium and values for the other factors in the option-pricing formula, the implied volatility or implied standard deviation can be estimated. 15 © 2013 Cengage Learning.

Determinants of Stock Option Premiums Explaining Changes in Option Premiums Economic conditions and market conditions can cause abrupt changes in the stock price or in the anticipated volatility of the stock price over the time until option expirations, leading to changes in the stock option’s premium. ■ Indicators Monitored by Participants in the Options Market Traders of options tend to monitor economic indicators because economic conditions affect cash flows of firms and thus can affect expected stock valuations and stock option premiums. 16 © 2013 Cengage Learning.

Speculating with Stock Options Excessive Risk from Speculation ■ Firms should closely monitor the trading of derivative contracts by their employees to ensure that derivatives are being used within the firm’s guidelines. ■ Firms should separate the reporting function from the trading function so that traders cannot conceal trading losses. ■ When firms receive margin calls on derivative positions, they should recognize that there may be potential losses on their derivative instruments and should closely evaluate those positions. 24 © 2013 Cengage Learning.

Hedging with Stock Options Hedging with Covered Call Options ■ Call options on a stock can be used to hedge a position in that stock. ■ When the stock declines in value, the premium received from selling the call partially offsets the losses incurred on the stock. ■ When the stock increases in value, the call will be exercised and the stock will be sold to the purchaser of the call option. 25 © 2013 Cengage Learning.

Hedging with Stock Options Hedging with Put Options ■ Put options are used to hedge when portfolio managers are concerned about a temporary decline in a stock’s value. ■ Hedging with LEAPs ■ Long-term equity anticipations (LEAPs) are options that have longer terms to expiration, usually between two and three years from the initial listing date. ■ These options are available for some large capitalization stocks, and they may be a more effective hedge over a longer term period than using options with shorter terms to expiration. 28 © 2013 Cengage Learning.

Options as Executive Compensation Limitations of Option Compensation ■ Many option compensation programs do not account for general market conditions. ■ Executives with substantial options may be tempted to manipulate the stock’s price upward in the short term, even though doing so adversely affects the stock price in the long term. ■ Backdating Options - In the late 1990s and early 2000s, some firms allowed their CEOs to backdate options they had already been granted to an earlier period when the stock price was lower. In 2006, firms that allowed backdating terminated the practice. 37 © 2013 Cengage Learning. All Rights Reserved.

SUMMARY  Stock options are traded on exchanges, just as many stocks are. Orders submitted by a brokerage firm are transmitted to a trading floor, where floor brokers execute the trades. Many trades are executed electronically.  The premium of a call option is influenced by the characteristics of the option and of the underlying stock that can affect the potential gains. In particular, the premium is higher when the market price of the stock is high relative to the exercise price, when the stock’s volatility is greater, and when the term until expiration is longer. For put options, the higher the market price of the stock relative to the exercise price, the lower the premium. The volatility of the underlying stock and the term to expiration are related to the put option premium in the same manner as they are to the call option premium. 39 © 2013 Cengage Learning.

SUMMARY (Cont.) 40  Speculators purchase call options on stocks whose prices are expected to rise and purchase put options on those expected to decrease.  Financial institutions can hedge against adverse movements in a stock by selling call options on that stock. Alternatively, they can purchase put options on that stock.  Financial institutions commonly hedge their stock portfolios by purchasing put options on stock indexes. They may also use stock index options as a tool for dynamic asset allocation, increasing their exposure when they have optimistic views about the stock market and reducing their exposure (buying put options on stock indexes) when they have pessimistic views. © 2013 Cengage Learning.

SUMMARY (Cont.)  41 Speculators purchase call options on interest rate futures contracts when they expect interest rates to decrease. Financial institutions with large holdings of long-term debt securities hedge against interest rate risk by purchasing put options on interest rate futures. Index options can be used to speculate on movements in stock indexes and require only a small investment. Put options on stock indexes can be purchased to hedge a stock portfolio whose movements are similar to that of the stock index. Options on stock index futures can be used to speculate on movements in the value of the stock index futures contract. Put options on stock index futures can be purchased to hedge portfolios of stocks that move in tandem with the stock index. © 2013 Cengage Learning. All Rights Reserved.
