Lesson 3: Risk and Return Flashcards
the time period an investment is held
or is the period in which you own an investment
Holding Period
the return for the period of investment
Holding Period Return
Formula of HPR
HPR = ending value of investment/ beginning value of investment
If you commit to invest Php 500 at the beginning of the year and get back Php 550 at the end of the year, what is your return for the period?
HPR = 550/500
= 1.10
HPY = HPR - 1
=1.10 -1
= 0.10 or 10%
Percentage Return
Holding Period Yield
Formula of Annual HPR
Annual HPR = HPR^1/n
Formula of Holding Period Yield
HPY = HPR - 1
Consider an investment that cost Php 1,000 and is worth Php 800 after a year. Calculate for the HPR and the HPY.
HPR = Php 800/Php 1,000
= 0.8
Annual HPR = 0.8^1/1
= 0.8
Annual HPY = 0.8 - 1
= -0.20 / -20%
Consider an investment that cost Php 2, 500 and is worth Php 3,500 after being held for 2 years. Calculate for the HPR and the HPY.
HPR = Php 3,500/Php 2,500
= 1.40
Annual HPR = 1.4^1/2
= 1.1832
Annual HPY = 1.1832 - 1
= 0.1832 or 18.32%
You have an investment of Php 1,000 held for 6 months and this investment earned Php 1,120. Calculate for the HPR and the HPY.
HPR = Php 1,120/Php 1,000
= 1.12
Annual HPR = 1.12 1/0.5
= 1.2554
Annual HPY = 1.2554 - 1
= 0.2554 / 25.54%
Consider an investment that cost Php 1,000 and is worth Php 750 after being held for 2 years. Calculate for the HPR and the HPY.
HPR = Php 750.00/Php 1,000
= 0.75
Annual HPR = 0.75^1/2
= 0.8660
Annual HPY = 0.8660 - 1
= -0.1339 or -13.4%
Mean Historical Rate of Return (Single Investment)
- Arithmetic Mean
- Geometric Mean
the sum of HPYs divided by the number of years
Arithmetic Mean
the nth root of the product of the HPRs for the number of years minus one
Geometric Mean
Formula of Arithmetic Mean
AM = Sum of HPY / n
Formula of Geometric Mean
={[(HPR1)(HPR2)…(HPRn)]^1/n} - 1
Find AM and GM
Year 1:
Beginning Value = 100
Ending Value = 115
HPR = 1.15
HPY = 0.15
Year 2:
Beginning Value = 115
Ending Value = 138
HPR = 1.2
HPY = 0.20
Year 3:
Beginning Value = 138
Ending Value = 110.4
HPR = .8
HPY = -0.20
AM = [(0.15)+(0.20)+(-0.20)] / 3
= 0.15 / 3
= 0.05 = 5%
GM = [(1.15) X (1.20) X (0.80)] 1/3 - 1
= (1.04) 1/3 - 1
= 1.03353- 1
= 0.03353 = 3.353%
Year 1:
Beginning Value = 50
Ending Value = 110
HPR = 2
HPY = 1
Year 2:
Beginning Value = 100
Ending Value = 50
HPR = .50
HPY = -.50
AM = [(1) + (-0.50] / 2
= 0.50 / 2
= 0.25 = 25%
GM = [(2) X (0.50)] 1/2 - 1
= (1) 1/2 - 1
= 1 - 1
= 0%
Measured as the weighted average of the HPYs for the individual investments in the portfolio
Mean Historical Rate of Return (Portfolio)
Weights used in computing are the relative beginning market values for each investment (dollar-weighted or value weighted)
