Arithmetic (mean) versus geometric (median) stock return
The expected return of a stock is ambiguous because, if we assume returns are normal, then price levels are lognormal. In which case, the mean does not equal the median future stock price.

FRM: Intro credit risk: expected loan return
The expected return on a loan adjusts for default risk. If p = probability of repayment, then 1-p = probability of non-repayment. The expected non-repayment, E[loan amount*(1-p)], is an expected loss (EL) covered by loan loss provisions (a contra-asset account). A "cost of doing business"

Capital asset pricing model (CAPM, FRM T1-9)
The CAPM is a ex ante single-factor model where the single-factor is the market's excess return: it says that we should expect an excess return that is proportional to the stock's beta, which is the stock's exposure to market's excess return, as measured by the stock's beta. Beta can be re
