Assume that you have just been hired as a financial analyst by Triple Play, a mid-sized California

Question:

Assume that you have just been hired as a financial analyst by Triple Play, a mid-sized California company that specializes in creating high-fashion clothing. Because no one at Triple Play is familiar with the basics of financial options, you have been asked to prepare a brief report that the firm's executives can use to gain a cursory understanding of the topic.

To begin, you gathered some outside materials on the subject and used these materials to draft a list of pertinent questions that need to be answered. In fact, one possible approach to the report is to use a question-and-answer format. Now that the questions have been drafted, you have to develop the answers.

a. What is a financial option? What is the single most important characteristic of an option?

b. Options have a unique set of terminology. Define the following terms:

(1) Call option

(2) Put option

(3) Strike price or exercise price

(4) Expiration date

(5) Exercise value

(6) Option price

(7) Time value

(8) Writing an option

(9) Covered option

(10) Naked option

(11) In-the-money call

(12) Out-of-the-money call

(13) LEAPS

c. Consider Triple Play's call option with a $25 strike price. The following table contains historical values for this option at different stock prices:

Stock Price Call Option Price

$25............... .$3.00

30...................7.50

35..................12.00

40..................16.50

45..................21.00

50................25.50

(1) Create a table that shows

(a) Stock price,

(b) Strike price,

(d) Option price, and

(e) The time value, which is the option's price less its exercise value.

(2) What happens to the time value as the stock price rises? Why?

d. Consider a stock with a current price of P = $27. Suppose that over the next 6 months the stock price will either go up by a factor of 1.41 or down by a factor of 0.71.

Consider a call option on the stock with a strike price of $25 that expires in 6 months. The risk-free rate is 6%.

(1) Using the binomial model, what are the ending values of the stock price? What are the payoffs of the call option?

(2) Suppose you write one call option and buy Ns shares of stock. How many shares must you buy to create a portfolio with a riskless payoff (i.e., a hedge portfolio)?

What is the payoff of the portfolio?

(3) What is the present value of the hedge portfolio? What is the value of the call option?

(4) What is a replicating portfolio? What is arbitrage?

e. In 1973, Fischer Black and Myron Scholes developed the Black-Scholes option pricing model (OPM).

(1) What assumptions underlie the OPM?

(2) Write out the three equations that constitute the model.

(3) According to the OPM, what is the value of a call option with the following characteristics?

Stock price = $27.00

Strike price = $25.00

Time to expiration = 6 month = 0.5 years

Risk-free rate = 6.0%

Stock return standard deviation = 0.49

f. What impact does each of the following parameters have on the value of a call option?

(1) Current stock price

(2) Strike price

(3) Option's term to maturity

(4) Risk-free rate

(5) Variability of the stock price

g. What is put-call parity?

Strike Price
In finance, the strike price of an option is the fixed price at which the owner of the option can buy, or sell, the underlying security or commodity. Portfolio
A portfolio is a grouping of financial assets such as stocks, bonds, commodities, currencies and cash equivalents, as well as their fund counterparts, including mutual, exchange-traded and closed funds. A portfolio can also consist of non-publicly...
