502-5 Security Analysis Flashcards
Describe the following methods of calculating an average share price: price-weighted average
The price-weighted (simple) average is calculated by adding the share prices and dividing by the total number of prices.
Describe the following methods of calculating an average share price: capitalization-weighted average
The capitalization-weighted average involves (1) weighting each price by the number of shares outstanding to get a total capitalization value for each stock, (2) adding the total values of the stocks, and (3) dividing by the total number of shares. Most indices are capitalization-weighted, and these are the indices that are used in modern portfolio theory
Describe the following methods of calculating an average share price: equally weighted average
The percentage change in the price of each security is computed, and then they are added together. This total is then divided by the total number of securities. Every stock has the same weighting in the index, regardless of the overall market capitalization.
Briefly explain how a price index works.
A price index allows for an easy comparison of prices over time. An initial price is used as the base year price, and all previous or subsequent years’ prices are compared to it by dividing the other year’s price by the base year’s price. For example, if the base year’s price is $1.00 and the subsequent year’s price is $1.15, the index is 1.15 (1.15 ÷ 1.00). This means that the current price is 15% greater than the base year’s price.
Describe the following methods of calculating average returns: arithmetic average return
An arithmetic average return is calculated by adding up the various returns and dividing the total by the number of returns.
Describe the following methods of calculating average returns: weighted-average return
A weighted-average return is calculated by (1) multiplying the return of each investment by its respective market value weight in the portfolio and then (2) adding together the weighted returns.
Describe the following methods of calculating average returns: geometric average return
The geometric average return is calculated by
(1) successively multiplying 1 plus each return by each other,
(2) taking the “Nth” root of the product (where “n” equals the number of returns), and
(3) subtracting 1 and multiplying by 100.
(4) Or it can be calculated by starting with $1 and seeing what it grows to based upon the given returns, and then solve for the return by doing a basic TVM calculation by inputting the (PV), FV, N, and then solving for I.
What is the holding period return?
The HPR is the sum of an investment’s income and change in price over a specified period, divided by the purchase price.
Under what circumstances can the HPR (Holding Period Return) be misleading?
The HPR has a major weakness in that it fails to consider when cash flows have occurred. If the holding period of an investment is greater than one year, the HPR overstates the true, annualized return. Conversely, if the time period of an investment is less than one year, the HPR understates the true, annual rate of return and the return must be annualized.
Define the internal rate of return.
The IRR is the interest rate that equates the present value of an investment’s cash flows with the cost of the investment
What are two problems associated with the use of the internal rate of return method?
First, the IRR method assumes that all cash flows received by an investor from an investment will be reinvested at the same IRR. This is unrealistic since interest rates vary and an investor seldom reinvests all such cash flows in the same investment product— and even if he or she does, there is no assurance that future returns on the reinvested dollars will equal the IRR rate.
Second, when more than one purchase is made in a time period, the IRR results may prove confusing. The timing of the subsequent dollar inflows may increase the weight of the returns from one period over those of another. The result could be an IRR that does not truly reflect the return on the investment itself. Instead, it reflects the return of the investor, due to the investor’s decisions about when to invest his or her available dollars. An investment (e.g., a mutual fund) may have a return of 10% for an entire year, whereas a particular investor in the fund may have a loss of 10% for the year, due to the investor’s decision to invest just before the fund’s price fell.
An alternative to the dollar-weighted rate of return is the time-weighted rate of return.
What is a time-weighted return?
A time-weighted return involves calculating the return for each period (HPR) and taking a geometric average. It is a compound rate that ignores the influence of the amount and timing of funds invested in each period.
What argument can be made for the use of a time-weighted return rather than a dollar-weighted return in evaluating the performance of a portfolio manager?
Because a manager cannot control the size and timing of money flowing in and out of an account, the use of a dollar-weighted return is inappropriate for evaluating portfolio performance.
Calculate the average annual compound rate of return (IRR) earned on a six- year investment in a stock using a dollar-cost-averaging plan. Assume that $5,000 is invested initially, that $500 more is invested at the end of each year, and that the market value of the stock at the end of six years is $14,000.
This problem requires the calculator to be set to “end.”
Average annual compound rate of return = 12.12%
Calculate the average annual compound rate of return (IRR) earned on a one- year investment in a mutual fund using a dollar-cost-averaging plan. Assume that $50 is invested at the beginning of each month and that the value of the mutual fund account at the end of the year is $635.
This problem requires the calculator to be set to “begin.”
I = 10.43%
How much money should a client invest today to achieve a return of 11% on an investment in a mutual fund if the client needs to accumulate a total retirement fund of $600,000 in 11 years? Assume that the client will also invest $24,000 at the end of each year in addition to the lump-sum investment made now.
This problem requires the calculator to be set to “end.”
PV = $41,413.62
If a client invests $60,000 now in a mutual fund and plans to add $8,000 to the fund at the end of each year for the next 22 years, how much will the client have accumulated at the end of that time if the fund has a total return of 13% per year?
FV = $1,726,757.89
