1. GS, Inc. stock is selling for $28 a share. A 3-month call on GS stock with a strike price of $30 is priced at $1.50. Risk-free assets are currently returning 0.3% per month. What is the price of a 3-month put on GS stock with a strike price of $30?

We will use Put- Call Parity to calculate the value of Put

c+ Xe^-(r(T-t)) = p+S

Put :To determine the value of Put given the value of Call

Inputs

Stock Price= S= $28.00

Exercise price = X= $30.00

Time to expiration = T-t= 3 months

Risk free rate = r = 0.30% per month

Call= $1.5000

Calculations

X * e ^(-r(T-t)) = $29.7312 =30x e ^ (-0.003x3)

p=c+Xe^(-r(T-t))-S)= $3.2312 =1.5 + 29.7312 - 28

Answer: Value of put= $3.2312

2. A firm has 100 shares of stock and 40 warrants outstanding. The warrants are about to expire, and all of them will be exercised. The market value of the firm's assets is $2,000, and the firm has no debt. Each warrant gives the owner the right to buy 2 shares at $15 per share. What is the price per share of the stock?

Market Value of firm's assets= $2,000

Number of warrants= 40

Each warrant gives the owner the right to buy 2 shares for $ 15 each

Number of additional shares= 2 x 40= 80

Additional cash for the company when the warrants are exercised= $1,200 =15x80

Value of the firm when the warrants are exercised= $2000 + $ 1200= $3,200

Total number of outstanding shares when the warrants are exercised=100+80= 180

Therefore price per share= $ 3,200 / 180= $17.78

Answer: Price per share of the stock= $17.78

3. What is the value of a 9-month call with a strike price of $45 given the Black-Scholes Option Pricing Model and the following information?

Stock price $48

Exercise price $45

Time to expiration 0.75

Risk-free rate 0.05

N(d1) 0.718891

N(d2) 0.641713

We will use Black Scholes Pricing Formula

Value of call= S N(d1) - X * e -r(T-t) * N(d2)

Inputs

Stock Price= S= $48.00

Exercise price = X= $45.00

Time ...
