Answer:
4.35%
Step-by-step explanation:
You buy a share of stock, write a one-year call option with X = $12, and buy a one-year put option with X = $12. Your net outlay to establish the entire portfolio is $11.50. What must be the risk-free interest rate? The stock pays no dividends.
Given the following :
1 - year call option with X = $12
1- year put option with X = $12
Net outlay to establish portfio = $11.50
No dividend
Risk-free interest rate :
(X / net outlay) - 1
(12 / 11.50) - 1
1.0434782 - 1
= 0.0434782
Expressing as a percentage :
0.0434782 * 100
= 4.347%
=4.35%
