Summary Introduction
To select: Comparison between the value of beta of S&P 500 index and call index with an exercise price of 1930 and 1940.
Introduction : Value of beta is depending on the elasticity value and exercise value. Hence higher exercise value is much more sensitive to the lower exercise price.

2. Derive the single - period binomial model for a put option. Include a single - period example where: u = 1.10, d
= 0.95, Rf = 0.05, SO = $100, X = $100. 3. Assume ABC stock's price follows a binomial process, is trading at SO =
$100, has u 1.10, d = 0.95, and probability of its price increasing in one period is 0.5 (q = 0.5). a. Show with a
binomial tree ABC's possible stock prices, logarithmic returns, and probabilities after one period and two periods. . b.
What are the stock's expected logarithmic return and variance for 2 periods and 3 periods? c. Define the properties of a
binomial distribution.
Let X = strike price and S = share price. A put option is deep out-of-the-money if _____________ (choose the best answer from the list below to complete the sentence).
X/S is between 1.01 and 1.05
X/S is between 1.06 and 1.15
X/S is between 0.95 and 0.99
X/S is between 0.85 and 0.94
X/S is equal to 1.00
If put A has T = 0.5, X = 50, sigma = 0.2, and a price of 10, and put B has T = 0.5, X = 50, sigma = 0.2, and a price of 12, which put is written on a stock with a lower price (and why)?
