The table below shows information for securities held by three investors, Daniel, David, and Diana.
| Investor | Expected Standard Deviation | Beta |
| Daniel | 30 | 1.60 |
| David | 25 | 1.80 |
| Diana | 20 | 1.40 |
Given that the expected return for David’s security is 14% and the riskfree rate is 2.5%, what is the expected return for the market?
The expected return for the market can be calculated using the following
equation:
E (Ri)= Rf+ β (E (Rm) −Rf) 14% = 2.5% + 1.80 (E (Rm) −2.5%) E(Rm)= 8.88%
