Study Notes
Risk and Risk Premiums
- Risk-free rate: The return rate earned with certainty.
- Risk premium: The expected return exceeding the risk-free rate.
- Excess return: Return surpassing the risk-free rate.
- Risk aversion: Reluctance to accept risk.
- Price of risk: Ratio of risk premium to variance.
Mean-Variance Analysis
- Used to rank portfolios using Sharpe ratios.
- Sharpe Ratio = (Portfolio Risk Premium) / (Standard Deviation of Excess Returns)
Historical Record & Time Series of Return
- Uses historical data to calculate variance and standard deviation.
- Scenario analysis is derived from historical returns.
The Normal Distribution
- Transforms a normally distributed return into a standard deviation score (Z-score).
- Can calculate returns using the standard normal score and standard deviation.
Normality over Time
- Returns are normally distributed over short time periods (up to one month).
- Using continuously compounded rates is advised for longer periods.
Value at Risk (VaR)
- Measures downside risk.
- Represents the worst loss with a given probability (usually 1% or 5%).
Deviation from Normality & Value at Risk
- Kurtosis: Measures the "fatness" of a distribution's tails, indicating extreme outcome likelihood.
- Skew: Measures the asymmetry of a distribution.
- Sharpe Ratio: Measures portfolio risk premium to standard deviation.
Portfolio Asset Allocation
- Expected Return of the Complete Portfolio: E (rC ) = y E (rp ) + (1 − y) r f
- Standard Deviation of the Complete Portfolio: C = y p
Capital Allocation Line (CAL)
- Plots the risk-return combinations achieved by varying allocations between risky and risk-free assets.
Risk Aversion and Capital Allocation
- Allocation (y) depends on risk aversion and the risk premium to variance ratio.
Passive Strategies and the Capital Market Line (CML)
- Passive strategies: Avoid security analysis and use market-index portfolios.
- Capital Market Line (CML): Uses a market-index portfolio as the risky asset in a capital allocation line.
Rates of Return
- Holding-Period Return (HPR): Calculated using the ending price, beginning price, and dividends.
- HPR is the sum of dividend yield and capital gains yield.
- Arithmetic Average: Sum of returns divided by the number of periods.
- Geometric Average: Single return that reflects the cumulative performance over multiple periods.
- Dollar-Weighted Average Return: Internal rate of return on an investment.
- Annual Percentage Rate (APR): Per-period rate multiplied by periods per year, ignoring compounding.
- Effective Annual Rate (EAR): Actual rate of return taking into account compounding.
Risk and Risk Premiums
- Risk-Free Rate: Return earned with certainty.
- Risk Premium: Expected return above the risk-free rate.
- Excess Return: Return exceeding the risk-free rate.
- Risk Aversion: Reluctance to accept risk.
- Price of Risk: Ratio of risk premium to variance.
- Mean-Variance Analysis: Ranking portfolios based on Sharpe ratios.
- Sharpe Ratio: Measures the portfolio's excess return relative to its standard deviation.
- Normal Distribution: Can be used to estimate potential return outcomes by converting them into standard deviation scores.
- Value at Risk (VaR): Measures downside risk, the worst loss over a given period with a specific probability.
- Kurtosis: Measures the "fatness" of distribution tails, indicating the likelihood of extreme outcomes.
- Skewness: Measures the asymmetry of distribution, showing its potential for extreme outcomes on one side.
Asset Allocation
- Asset Allocation: Portfolio choices across different investment classes.
- Complete Portfolio: The entire portfolio, including risky and risk-free assets.
- Capital Allocation: The choice between risky and risk-free assets.
- Risk-Free Asset: Investments with minimal risk, like U.S. Treasury bonds, money market instruments, or price-indexed government bonds.
Historical Record
- Scenario Analysis: Estimates potential return outcomes based on historical data.
- Variance and Standard Deviation: Calculated from a time series of returns.
- World Portfolios: Represent a diverse range of investment opportunities across different countries.
- Standard & Poor's 500 (S&P 500): Tracks the performance of the 500 largest U.S. companies by market capitalization.
- U.S. Small Stocks: Measures the performance of the smallest 20% of stocks on the NYSE, NASDAQ, and AMEX.
- World Bonds: Represents bonds issued by developed economies included in the world large stocks portfolio.
- U.S. Treasury Bonds: Tracks a specific index of long-term U.S. Treasury bonds.
Rates of Return
- Holding-Period Return (HPR) measures the rate of return over a given investment period
- HPR is comprised of the dividend yield and the capital gains yield
- Arithmetic average is the sum of returns divided by the number of periods
- Geometric average is a single period return that yields the same cumulative return as the sequence of actual returns
- Dollar-weighted average return is the internal rate of return on an investment
Annualizing Rates of Return
- APR (Annual Percentage Rate) is the per-period interest rate multiplied by the number of periods per year and doesn’t account for compounding
- EAR (Effective Annual Rate) is the actual rate at which an investment grows and accounts for compounding.
Interest Rates
- Nominal interest rate is the interest rate without considering inflation
- Real interest rate is the return on an investment after taking inflation into account
- The Fisher Equation states that the nominal interest rate is equal to the real interest rate plus the expected inflation rate
- The difference between the nominal interest rate and the real interest rate is the amount of inflation
Risk and Risk Premiums
- Risk premium is the expected return in excess of risk-free securities
- Risk aversion is the reluctance to accept risk
- Mean-Variance Analysis ranks portfolios based on their Sharpe Ratios
- Sharpe Ratio is the ratio of a portfolio's risk premium to its standard deviation.
- The Sharpe Ratio is a measure of risk-adjusted return
- Scenario analysis is a method of estimating the expected return and risk of an investment by considering different possible economic scenarios
- Probability distribution is a way of representing the possible outcomes of an investment and their associated probabilities
- Variance measures the expected value of the squared deviation from the mean
- Standard deviation is the square root of the variance
- The normal distribution is a bell-shaped curve that is commonly used to model returns on investments
- Value at risk (VaR) is a measure of downside risk that estimates the maximum potential loss for a given confidence level.
- Kurtosis measures the fatness of the tails of the probability distribution
- Skew measures the asymmetry of the probability distribution
Historical Record
- Scenario Analysis uses historical return data to estimate future returns and risk
- Variance and Standard Deviation are calculated from historical data
- World Large Stocks include 24 developed countries and approximately 6000 stocks
