AF4 Calculations Flashcards
Standard Deviation - Calculation?
What does it tell you?
Return - mean (of returns)
= Result squared
Mean of result squared
Find the square root
Standard deviation helps determine market volatility or the spread of asset prices from their average price. When prices move wildly, standard deviation is high, meaning an investment will be risky. Low standard deviation means prices are calm, so investments come with low risk.
CAPM Calculation?
What does it tell you?
= Rf + B (Rm - Rf)
Describes the relationship between systematic risk and the expected return for assets.
Rests on two assumptions: (1) securities markets are efficient (that is, relevant information about the companies is quickly and universally distributed and absorbed); (2) these markets are dominated by rational, risk-averse investors, who seek to maximize satisfaction from returns on their investments.
Holding Period Return Calculation?
What does it tell you?
D + V1 - V0
/
V0
Total return earned on an investment during the time that it has been held.
MWR Calculation?
What does it tell you?
D + V1 - V0 +/- C
/
V0 +/- C * n/12
Calculates the performance of an investment that accounts for the size and timing of deposits or withdrawals
TWR Calculation?
What does it tell you?
1+R = (1+R)(1+R2) = R is holding period return -
D + V1 - V0
/
V0
The TWR is a measure of the compound rate of growth in a portfolio. The TWRR measure is often used to compare the returns of investment managers because it eliminates the distorting effects on growth rates created by inflows and outflows of money.
Interest Yield Calculation?
What does it tell you?
Coupon
/
Clean price
The annual return that an investor receives from the bond investment
(GRY) Redemption Yield Calculation?
What does it tell you?
Interest Yield +/- gain or loss / yrs to maturity
/
Clean Price
- 100
The yield is the annual income and anticipated capital gain (or loss) from holding a bond until maturity. The yield represents the expected annual returns.
If less than Interest Yield then there will be a capital loss, and vice versa.
Sharpe Ratio Calculation?
What does it tell you?
Rp - Rf
/
Standard Deviation
The Sharpe ratio adjusts a portfolio’s past performance—or expected future performance—for the excess risk that was taken by the investor.
Assumes that returns are normally distributed.
Can be manipulated by portfolio managers seeking to boost their apparent risk-adjusted returns. This can be done by lengthening the measurement interval.
Alpha Calculation?
What does it tell you?
Rp - CAPM
Alpha is the excess return on an investment after adjusting for market-related volatility and random fluctuations.
Tells investors whether an asset has consistently performed better or worse than its beta predicts.
Information Ratio Calculation?
What does it tell you?
Rp - Rb
/
Tracking Error
A measurement of portfolio returns beyond the returns of a benchmark, compared to the volatility of those returns.
Attempts to identify the consistency of the performance.
A low tracking error means the portfolio is beating the index consistently over time. A high tracking error means that the portfolio returns are more volatile over time and not as consistent in exceeding the benchmark.
EPS Calculation?
What does it tell you?
Net income
/
Shares in issue
How much money a company makes for each share of its stock.
P/E Calculation?
What does it tell you?
Price per share
/
EPS
The price-to-earnings (P/E) ratio relates a company’s share price to its earnings per share.
A high P/E ratio could mean that a company’s stock is overvalued, or else that investors are expecting high growth rates in the future.
Dividend Yield Calculation?
What does it tell you?
Dividend
/
Share Price
* 100
The percentage of a company’s share price that it pays out in dividends each year.
Dividend Cover Calculation?
What does it tell you?
EPS
/
DPS
Measures the number of times that a company can pay dividends to its shareholders.
P/B Calculation?
What does it tell you?
Share Price
/
NAV
Measures the market’s valuation of a company relative to its book value.
