### Mock test 2

Tina’s portfolio has a large (negative) theta. She is planning to add a call option on a non dividend paying stock to her portfolio. She doesn’t want the new option to change the overall theta of her portfolio by a large extent. The 6-month call options which she is considering have a time to maturity of 1 month. The current stock price is \$105. Which of the following options should she buy?
a. Call option with Strike price = \$105 Incorrect
b. Call option with Strike price = \$100 Correct
c. Call option with Strike price = \$115 Incorrect
d. Call option with Strike price = \$110 Incorrect
The correct answer is Call option with Strike price = \$100.
Explanation.
Theta curve for out of the money options approaches to 0 as the time to expiry nears. Tina should buy the out of the money call option which is the one with strike price of \$100.

But y not C or D because ITM call option also aproaches Zero for theta.

Note that the question says that she does not want to change the theta of the portfolio.
That mean, she must add an option with a large (negative) theta since the portfolio has a large (negative) theta.
Otherwise, if she adds a low theta stock, that would lower the overall theta of the portfolio.

Think about it this way: Lets say we have a portfolio with a Beta of 2. Now, if we add a risk free asset (Beta = 0), that would LOWER the beta of the portfolio.

Hope this helps!

Yes exactly, but in that case she should choose at the money option because that has highest negative theta. i.e answer should be A.?? Correct.??
