12. CAL Capital Allocation Line (when one asset is rf)

rA = Optimal Risky Asset

rf = Risk Free Asset

Concept Point for line:

• For defining a straight line we require two points.

• A straight line will have only one slope [which is nothing but its angle with x-axis]

= y2 – y1

x2 – x1

• A general Equation of a straight line

Y = a + bx

rp

Return Y

Risk X

Y2= rA

Y1= rf

x1= 0 x1= σA

i. Slope of CAL :

= Excess return over risk free return rA - rf

Total risk of A σA

ii. Equation of CAL:

rp = rf + rA - rf σp

σA

Risky return for portfolio p

Risky free return for portfolio p

Price of risk

Risk of Portfolio p

Risk premium for portfolio p
