How do you caluclate a Holding per Return (HPR))?
If a daily return is 0.80%, how would you calculate an annualized return?
= (1.0008) ^365
Define the required rate of return…
The minimum level of expected return that an investor requires in order to invest.
How do you calculate Expected Alpha?
= Expected Return - Required Return
If an asset’s price equals the intrinsic value price, what is the expected alpha?
0
How do you calculate an expected return?

- Calculate the mean return on the index
- Select a proxy for the risk free rate
When estimating an Equity Risk Premium, explain when Arthimetic Mean and Geometric Mean are most appropriately used
- Arithmetic - when looking at a single period
- Geometric - the preferred method for use in historical estimates
Explain Survivorship Bias….
tends to inflate historical estimates of ERP because poorly performing or defunct companies have been removed from the index
How do you calculate the Gordon Growth Model (GGM) equity risk premium?
= (1 yr forecasted dividend yield on market index) + (consensus long term earnings growth rate) - (long term government bond yield)

- The assumption of a stable growth rate, which is often not appropriate in rapidly growing economies
What is the formula of the Macroeconomic Model created by Ibotson & Chan?
How do you calculate expected inflation (EINFL)?
= (1+YTM on 20 yr t-bonds) / (1+ YTM on 20 yr TIPS) - 1
