Questions:

730.1 A non-dividend paying stock is currently trading at a price $35.00 when its volatility is 30.0% and the riskfree rate is 3.0%. Consider a chooser option with a strike price of $30.00 that gives the holder the right to choose (a call or put option) in three months and the chosen option, at that point in time, will have a remaining time to maturity of nine months; i.e., T1 = +0.25 years and T2 = +1.0 years. The price of this chooser is $7.710. Which of the following changes, ceteris paribus, will INCREASE the value of this chooser?

a. Dividend increase to 4%
b. Volatility decrease to 20%
c. Stock drops to $30.00
d. Increase T1 to six months


730.2 Consider a one-year barrier call option on a non-dividend-paying stock with a volatility of 30.0% per annum when the stock's price is $25.00 and the option's strike price is $20.00. The risk-free rate is 3.0%. The price of a regular call (i.e., without the barrier) in this case is $6.32. This barrier option has a barrier at $18.00 such that, if it is a knock-in (aka, down-and-in) its price is only $0.22. Each of the following statements is true (or at least plausible!) EXCEPT which statement must be false?

a. The corresponding knock-out (aka, down-and-in) must have a price of about $6.10
b. If the barrier is increased to $22.00, then the price of this knock-in must be higher than $0.22
c. If the barrier is increased to $22.00, then the price of the corresponding knock-out must be lower than $6.10
d. If the barrier is increased to $28.00, then the price of this knock-in will be $6.32 and the price of the corresponding knock-out will be zero


730.3. A non-dividend-paying stock with a current price of $40.00 and a volatility of 30.0% per annum when the risk-free rate is 4.0%. Consider a one-year barrier option with a barrier, H = $43.00, and a strike price, K = $45.00. Please note that the corresponding regular (i.e., without the barrier) put option price is $6.75. Which of the following instances of this barrier option has the LOWEST price?

a. Knock-in call
b. Knock-out call
c. Knock-in put
d. Knock-out put
