We know the following expected returns for stocks A and B, given different states of the economy:
State (s) | Probability | E(rA,s) | E(rB,s) |
Recession | 0.3 | -0.01 | 0.04 |
Normal | 0.5 | 0.14 | 0.07 |
Expansion | 0.2 | 0.22 | 0.11 |
Note: If you can, it is much faster to solve these problems in a spreadsheet. However, the answer cannot be had simply by using the built-in AVERAGE() or STDEV() functions. If you are somewhat familiar with Excel, you might look into the SUMPRODUCT() function which is widely used to calculate weighted sums.
A: What is the expected return for stock A? 3+ Decimals
B: What is the expected return for stock B? 3+ Decimals
C:What is the standard deviation of returns for stock A? 3+ Decimals
D: What is the standard deviation of returns for stock B? 4+3+ Decimals
