Eg.
Initial Value: 1,000
Return 1: 4%
Return 2: -3%
Return 3: 7%
1000 * (1.04) * (0.97) * (1.07) = 1079.42
What is the difference between price return and total return?
price return is based on price ending period and beginning period.
total return includes income as well as price ending period and beginning period
What is price return formula?
PRi = Pi1 - Pi0 / Pi0
What is total return formula?
TRi = (Pi1 - Pi0 + Inc1) / Pi0
Whats the formula for calculating the price returns for an index given different weight and returns?
PR1 = w1PR1 + w2PR2 + + wN*PRN
N= number of stocks
Whats the formula for calculating the total returns for an index given different weight and returns?
TR1 = w1TR1 + w2TR2 + + wN*TRN
When selecting or creating an index what 3 things must you decide on? TIR
