Risk premium equation?
Risk premium = expected return - risk free rate
Risk premium = E(Ri) - Rf
Expected return
Return on risky asset expected in future
Calculating variance and standard deviation squared?
variance = (Standard deviation)^2
(Standard deviation)^2=
(standard deviation)^2 X (probability) + (standard deviation)^2 X (probability) +…etc
Portfolio
Group of assets such as stocks and bonds held by
An investor
Portfolio watch
Percentage of portfolio’s total value in particular investment
Total return equation?, systematic/unsystematic components?
Total return = expected return + unexpected return
Total return =

Announcement
Announcement = expected part + surprise
Systemic risk AKA Market risk
Risk that influences large number of assets
Unsystematic risk AKA Unique or asset specific risk
Risk that affects at most a small number of assets
Principle of diversification
Spreading an investment across a # of assets will
Eliminate some, but not all of the risk
What is unsystematic risk eliminated by?
Diversification
Total risk equation
Total risk = systematic risk + unsystematic risk
Systematic risk principle
Expected returns on risky asset depends only on that
Asset’s systematic risk
Beta coefficient
Amount of systematic risk present in particular risky
Asset relative to that in an average risky asset
What must be true about the reward to risk ratio?
Be same for all assets in the market
