According to the Black-Scholes formula, what will be the hedge ratio (delta) of a call option as the stock price becomes infinitely large? Explain briefly.
In the Black-Scholes option pricing model, the value of a call is inversely related to: a. the risk-free interest stock b. the volatility of the stock c. its time to expiration date d. its stock price e. its strike price
Given the information in the table below, which of the following statements is correct, assuming that either security will be held in a portfolio with other investments?
Stock
Expected Return
Required Return
Beta
Standard Deviation
A
10%
12%
0.9
25%
B
8%
5%
0.3
35%
Question 26 options:
The investor should purchase both stocks because their beta is less than that of the market.
The investor should purchase A since its risk, as measured by standard deviation, is the lowest.
The investor should purchase A because it requires the highest rate of return.
The investor should purchase B since its expected return exceeds its required return.
