The correct answer is D. All of the above.
The normal rate of return is the rate of return that investors expect to earn on an investment. It is determined by a number of factors, including the degree of risk involved, the current rate of interest on gilt-edged securities, and the weighted average cost of capital.
The degree of risk involved is the likelihood that the investment will not earn the expected return. The higher the risk, the higher the expected return.
The current rate of interest on gilt-edged securities is the rate of return on government bonds. It is a benchmark for other investments, and it is used to determine the risk-free rate of return.
The weighted average cost of capital is the average cost of capital for a company. It is calculated by taking into account the cost of debt and the cost of equity, and it is used to determine the minimum rate of return that a company must earn on its investments.
All of these factors are important in determining the normal rate of return for the valuation of shares in market value method.
