1. In caclulating WACC, how can you find Rm (the market return) and b (systematic risk)? Actually, i dunno how many years should be used for the market return (i.e. if i used Dow Jones as an index ref, am i looked at 1 year or 10 years mkt return?) For the systematic risk, i know it should be involved a complex calculation behind the theory, am i needed to really calculate the b? (coz it seems impracticable which involved matrix..) or i can simply assigned "1" to the company if i think it moves in the same pace with market? Finally, since all of our subsidiaries are private companies, how can i find the market value of the equity shares?
