Now I have P0 from step 4 and equity BV from step 6… justified P/BV = 22.69688 / 8.76057 = 2.59080 !!! what makes this answer differs from the answer given in the book!!!
Thanks for your reply. The difference between my work and yours is that you used expected NI instead of current NI. I cannot relate what’s the rationale for that?
The dividend at the end of the coming year is based on the coming year’s net income, not the previous year’s net income.
Furthermore, ROE is calculated using the book value of equity at the beginning of the year, not at the end of the year, much as the rate of return on an investment is the amount of the return divided by the initial investment, not the terminal value.
Think of the 23% as you starting a business with an equity capital of $100 today (BV_0) and use it to generate a net income of $23 at the end of the year (NI_1). That’s how much you have generated on your equity investment.
If we were to do 23/123 ( \frac{NI_1}{BV_1} ), it would not be meaningful as a measure of return.
