Estimating Cost of Equity: Deutsche Bank
! Deutsche Bank is in two different segments of business - commercial banking
and investment banking.
- To estimate its commercial banking beta, we will use the average beta of
commercial banks in Germany.
- To estimate the investment banking beta, we will use the average bet of investment
banks in the U.S and U.K.
! To estimate the cost of equity in Euros, we will use the German 10 - year bond
rate of 4. 05 % as the riskfree rate and the US historical risk premium ( 4. 82 %)
as our proxy for a mature market premium.
