Types of Options • Types of Options – Puts – Calls – Rights – Warrants • All of the above are types of derivative securities, which derive their value from the price behavior of an underlying real or financial asset Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -3

All rights reserved. 14 -4

Options: Puts and Calls (cont’d) • Options allow buyers to use leverage; investors can benefit from stock-price movements without having to invest a lot of capital • A given percentage change in a stock’s price usually generates a larger percentage change in an option’s price • Puts and calls are created by individual investors, not by the organizations that issue the underlying financial asset Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -5

Options: Puts and Calls (cont’d) • Option Buyer – Has the right to buy (in the case of a call option) or sell (in the case of a put option) an underlying asset at a fixed price (called the exercise price or strike price) for a given period of time – To acquire this right, the option buyer must pay the option seller a fee known as the option premium (or option price) – Buyers do not have to exercise their options; they can walk away if exercising the option isn’t profitable Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -6

Options: Puts and Calls (cont’d) • Option Seller (also called the option writer) – Receives the option premium from the buyer up front – Has the obligation to sell (in the case of a call option) or buy (in the case of a put option) the underlying asset according to the terms of the option contract – Whereas option buyer can walk away if exercising the option is unprofitable, option seller cannot walk away Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -7

Options: Puts and Calls (cont’d) • Put and call options trade in the open market much like any other security and may be bought and sold through securities brokers and dealers • Values of puts and calls change with the values of the underlying assets • Other factors influence option prices (e. g. , an option’s value is usually higher if there is more time before the option expires) Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -8

Advantages of Puts and Calls • Allows use of leverage – Leverage: the ability to obtain a given equity position at a reduced capital investment, thereby magnifying total return • Option buyer’s potential loss is limited to fee paid to purchase the put or call option • Investors can make money when value of assets go up or down Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -9

Disadvantages of Puts and Calls • Investor does not receive any interest or dividend income • Options expire; the investor has limited time to benefit from options before they become worthless • Options are risky; a small change in the price of the underlying asset may make an option worthless • Option seller’s exposure to risk may be unlimited Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -10

How Calls Work • Call: an option that gives the holder (buyer) the right to buy the underlying security at a specified price over a set period of time – The buyer of the call option wants the price of the underlying asset to go up – The seller of the call option wants the price of the underlying asset to go down Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -11

How Calls Work (cont’d) • If the price of the underlying asset goes above the option’s strike price: – The option holder will purchase the asset at the strike price and then sell it at the higher market price, making a profit – The option writer must sell the asset at the strike price (which is lower than the asset’s market price). – If the seller does not already own the underlying asset, then the seller will have to purchase it at the higher market price • Covered call: seller owns the underlying asset • Naked call: seller does not own the underlying asset Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -12

How Calls Work (cont’d) • If the price of the underlying asset goes down: – The buyer will let the call option expire worthless and lose the option premium – The seller will keep the option premium and make a profit Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -13

How Calls Work (cont’d) • Example: Assume the market price for a share of common stock is $50. An investor buys a call option which grants the right to purchase 100 shares of the stock at a strike price of $50. The call premium is $500 • If the market price of the stock goes up to $75 per share, the investor will exercise the right to purchase 100 shares for $50. The investor then sells the shares on the open market for $75. • The investor’s net profit will be: • The option seller’s loss will be: • Notice that the buyer’s profit equals the seller’s loss; options are a zero-sum game Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -14

How Calls Work: The Value of Leverage • In the previous example, the option buyer makes a profit of $2, 000 after investing just $500 in capital • The buyer’s total return using the call option was: • Rather than buying the option, the investor might have simply purchased 100 shares of stock directly. At a price of $50 per share, the cost of 100 shares would have been $50, 000. If the share price had risen to $75, the investor would have earned a $2, 500 profit. The total rate of return on the investment would have been: • The same $25 increase in the stock price generates a much higher rate of return for the option investor than for an investor who buys stocks directly Copyright © 2014 Pearson Education, Inc.

How Calls Work (cont’d) • Example: Assume the market price for a share of common stock is $50. An investor buys a call option to purchase 100 shares of the stock at a strike price of $50 per share. The option premium is $500. • If the market price of the stock goes down to $25 per share, the investor will allow the call option to expire worthless. • The option buyer’s loss will be: • The option seller’s profit will be equal to the option premium: Copyright © 2014 Pearson Education, Inc.

How Puts Work • Put: an option that enables the holder (buyer) to sell the underlying security at a specified price over a set period of time – The buyer of the put option wants the price of the underlying asset to go down – The seller of the put option wants the price of the underlying asset to go up Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -17

How Puts Work (cont’d) • If the price of the underlying asset goes below the put option’s strike price: – The put owner will buy the underlying asset, paying the open-market price, and then force the put seller to buy the asset at the higher strike price, making a profit – The seller will pay a price higher than the market price • If the price of the underlying asset goes up: – The buyer will let the put option expire worthless and lose the option premium – The seller will keep the option premium and make a profit Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -18

How Puts Work (cont’d) • Example: Assume the market price for a share of common stock is $50. An investor buys a put option that grants the right to sell 100 shares of the stock at a strike price of $50. The option premium is $500. • If the market price of the stock goes down to $25 per share, the investor will purchase 100 shares of stock in the open market for $25 each. Then the investor exercises his right to sell those shares to the put seller for $50 each • The buyer of the put option earns a profit of $2, 000: • The seller’s loss will be: Copyright © 2014 Pearson Education, Inc.

A put option to sell 100 shares of the stock at a strike price of $50 per share may be purchased for $500. • If the market price of the stock goes up to $75 per share, the buyer will allow the put option to expire worthless. • The buyer’s loss will be: • The seller/maker/writer’s profit will be: Copyright © 2014 Pearson Education, Inc.

Valuation of Stock Options • Option Premium (Price): the quoted price the investor pays to buy a listed put or call option • Option premiums (prices) are affected by: – Intrinsic value: based upon current market price of underlying assets – Time Premium: amount that option price exceeds the fundamental value Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -26

Intrinsic Value of a Call Option • The intrinsic value of a call option equals the difference between the market price of the stock and the strike price of the option, or zero, whichever is greater • Example: Suppose a call option has a strike price of $50 – If the underlying stock price is $75, the call’s intrinsic value is $25 (actually, $2, 500 because the call grants the right to buy 100 shares) – If the underlying stock price is $25, the call’s intrinsic value is $0 Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -27

Intrinsic Value of a Put Option • The intrinsic value of a put option equals the difference between the strike price of the option and the market price of the stock, or zero, whichever is greater • Example: Suppose a put option has a strike price of $50 – If the underlying stock price is $25, the put’s intrinsic value is $25 (actually $2, 500 because the put grants the right to sell 100 shares) – If the underlying stock price is $75, the put’s intrinsic value is $0 Copyright © 2014 Pearson Education, Inc.

Valuation of Stock Options • In-the-Money – Call option: when the strike price is less than the market price of the underlying security – Put option: when the strike price is greater than the market price of the underlying security – When an option is in the money, its intrinsic value is greater than zero • Out-of-the-Money – Call option: when the strike price is greater than the market price of the underlying security – Put option: when the strike price is less than the market price of the underlying security Copyright © 2014 Pearson Education, Inc. All rights reserved. 14 -30

Option Pricing Models • The best known option pricing model is the Black and Scholes Model • The model states that an option’s price depends on five variables – The – The option’s strike price option’s expiration date price of the stock risk free rate of interest stock’s volatility Copyright © 2014 Pearson Education, Inc.
