Stock A: SD = 12%, Average Return = 10%
Stock B: SD = 8%, Average Return = 5%
Which one is more risky?
What formula to use?

Coefficient of Variation: SD / Average Return
Higher CV more risk

Correlation Cor/ Correlation Efficiency
Measures what and how it’s measured?

Cor = (Cov 1-2) / ((SD1)(SD2))
+1 means 2 assets perfectly correlated, No diversification
0 means there is no relation between 2 assets
-1 means they are perfectly correlated
Diversification starts when Cor < 1

Beta measures what and how it’s measured?

It measures 1 security risk relative to the market.
Beta of bench market risk is: 1
If security Beta > 1, it means it’s more riskier than the market.
If its Beta < 1, it’s less riskier than the market.

Beta vs. SD, what’s the difference in measurements?

Beta measures Systematic, market risk
SD measures total risk
Beta1= Cov 1-m / (SD m ^2)
Or
Beta1= (Cor 1-m * SD1)/ SD m
Beta = R 1 / R m

CML Capital Market Line
How is it relate to CAPM? What does it measure?

It’s the macro aspect of CAPM
It’s the relationship between risk and return of ALL possible portfolios.
It’s NOT used to evaluate 1 security
It uses SD in calculation

SML Security Market Line
What does it measure and how is it different from CML?

It measures the risk and return as defined in CAPM formula.
If Rp > SML, it’s under valued, buy signal
If Return of portfolio < SML, over valued, do not buy
SML uses Beta, CML uses SD

What’s Information Ratio measuring?

It measures Portfolio performance
Relative risk adjusted performance
It measures the excess return provided by a fund manager, relative to a benchmark. Higher IR the better.

Which fund would you recommend? Use Treynor Index
Growth Fund: Beta 1.2, Rf 3%, actual return 12%
Index Fund: all same except actual return is 9%

Jensen ‘s Alpha
What does it measure? How it measures it?

It measures Portfolio Managers performance.
Alpha = Rp - SML/CAPM
Rp - ((Rf+Beta p (Rm-Rf))
+Alpha means manager did better than market
-Alpha means manager did worse than market

D’s mutual fund returned 19% last year with Beta 2. Risk free 3%, market return 8%. SD 18%. What would you tell D about the performance? What ratio would you use and why or why not.

Can not use Treynor, Sharpe because there is not enough data for comparison assets. Jensen but Jensen is more straight forward.

R^2
When a portfolio is considered diversified
What ratio to use to judge performance

> 0.7 means more diversified, Beta, Treynor, Jensen should be used to measure recommendations
If it’s < 0.7, not diversified, SD, Sharpe should be used

Which fund would you recommend?
A: SD 12%, R^2 0.92, Alpha 2, Shape 1.2
B: SD 13%, R^2 0.90, Alpha 1.8, Sharpe 1.5

Since R^2 > 0.7, use Jensen or Treynor
