502-3 Modern Portfolio Theory and Behavioral Finance Flashcards
Explain how each of the tools listed might be used by an investor who is constructing an investment portfolio: capital asset pricing model
to determine the required return for a security when the risk-free rate, the market return, and the security’s beta are known
Explain how each of the tools listed might be used by an investor who is constructing an investment portfolio: capital market line
The macro version of Capital Asset Pricing Model (CAPM)
A graph showing the relationship between total risk (standard deviation) and return for a portfolio of securities in which risky securities are combined with a risk-free asset. As riskier securities are added, and standard deviation goes up, then required return also goes up
Explain how each of the tools listed might be used by an investor who is constructing an investment portfolio: efficient frontier
to plot the various combinations of security portfolios that represent the optimal combination of assets for any specific level of risk that an investor is willing to bear
Explain how each of the tools listed might be used by an investor who is constructing an investment portfolio: optimal portfolio
to determine the specific combination of assets that will have the greatest probability of maximizing an investor’s expected return at the investor’s given level of risk
Explain how each of the tools listed might be used by an investor who is constructing an investment portfolio: security market line
The micro version of Capital Asset Pricing Model (CAPM)
A graph showing the relationship between systematic risk (measured by beta) and the required return for an investment for any given level of risk. The CAPM determines the SML
Explain how each of the tools listed might be used by an investor who is constructing an investment portfolio: arbitrage
to identify mispriced securities, especially when a single security is selling at different prices in different organized markets
What does an indifference curve indicate?
An indifference curve indicates an investor’s willingness to bear risk. The investor has the same level of satisfaction from any of the combinations of risk and return shown by all the alternatives on the curve.
In the CAPM formula, what is the term (Rm – Rf) called?
It s called the market risk premium.
Explain how portfolio risk (σp) is used to develop the efficient frontier in the Markowitz model.
A graph is constructed in which the horizontal axis measures the risk associated with the portfolio (σp) and the vertical axis measures the expected return of the portfolio. Various combinations (portfolios) of securities are plotted on the graph, and a curve emerges that defines the efficient set (frontier) of portfolios, which are those portfolios that offer the highest return for any given level of risk. No single portfolio on the efficient frontier is superior to any other single portfolio on the frontier. Each portfolio has a different risk level and a return consistent with that risk level.
What is an unattainable or non feasible portfolio?
What is an attainable but inefficient portfolio?
What is an efficient portfolio?
Unattainable or nonfeasible portfolios do not exist (i.e., there is no such combination of risk and return that is achievable for an extended period of time). Attainable but inefficient portfolios offer an inferior return for a given amount of risk; they are inefficient because the investor can get a higher return without increasing risk or get the indicated return at a lower risk level. Efficient portfolios are those that offer the highest return for a given level of risk (or the lowest risk for a given level of return).
Can the Markowitz model by itself be used to select an optimal portfolio for an investor? Explain your answer.
Rational investors want an optimal portfolio that offers the highest return for a given level of risk or the least amount of risk for a given level of return. By itself, the Markowitz model does not identify the optimal portfolio; it only identifies the efficient frontier of portfolios. The optimal portfolio occurs at the point of tangency of the indifference curve and the efficient frontier. The optimal portfolio for an investor is determined by combining the efficient frontier and the investor’s willingness to bear risk.
When the CFP Board refers to the CAPM and does not specify which form is being addressed, is it referring to the Security Market Line (SML) or the Capital Market Line (CML)
When the CFP Board refers to the CAPM and does not specify which form is being addressed, it is the security market line (SML) that is being referred to.
Using the explanations for a security’s return distinguish the arbitrage pricing theory from the capital asset pricing model. - Variables affecting stock prices
Arbitrage Pricing Theory: It is a multivariate model that recognizes that variables other than market return and beta can affect stock prices.
Capital Asset Pricing Model: It assumes that only a market return and a beta with respect to that market are necessary to explain all stock returns.
Using the explanations for a security’s return distinguish the arbitrage pricing theory from the capital asset pricing model. - Relationship between risk and return
Arbitrage Pricing Theory: The relationship between a stocks return and risk is not a straight line.
Capital Asset Pricing Model: Assumes a straight line between risk and return.
Using the explanations for a security’s return distinguish the arbitrage pricing theory from the capital asset pricing model. - Factors that affect return
Arbitrage Pricing Theory: Factors that affect return fall into the categories of sector influences and systematic influences.
Capital Asset Pricing Model: The only factor that explains return is a stocks beta.
Under Arbitrage Pricing Theory (APT), research suggests that four unanticipated factors have the greatest impact on stock returns. What are these four factors?
- changes in inflation
- changes in interest rates
- changes in industrial production/gross domestic product
- changes in risk premiums
Under APT, when a factor has a numerical value of zero, what impact on return does that factor have?
That factor has no impact on the return.
How would a casino operator or forest products company be affected if inflation unexpectedly rises?
The casino operator would experience little impact when inflation rises; people tend to gamble regardless of economic conditions. They may be more inclined to try to increase their net worth when inflation eats into their paychecks.
Forest products companies have the majority of their net worth tied up in their trees; any rise in inflation tends to substantially increase the value of their tree inventories.
How would am electric utility or food retailer when be affected when interest rates unexpectedly increase?
People must purchase food regardless of interest rate levels.
Electric utilities are very highly leveraged, and increased interest rates have a direct impact on their net profit. The value of the utilities’ securities would decrease.
Hou would telephone utility or durable goods manufacturer be affected when when consumer spending unexpectedly decreases?
People will use their telephones regardless of the condition of the economy.
When people believe their incomes are in jeopardy, they will likely cut back on all but essential consumer products, such as food and clothing; they will defer purchases of durable goods, such as furniture.
List some of the major characteristics of each of these life cycle phases.- accumulation phase
Early career phase with career and family beginning. Income low and growing, limited amount of assets, home most significant asset, long-term time horizon for investments and retirement.
List some of the major characteristics of each of these life cycle phases.- consolidation phase
Mid-to-late career phase with income exceeding expenses. Home equity and retirement account balances may result in large net worth. Investment time horizon is still long.
List some of the major characteristics of each of these life cycle phases. -spending phase
After retirement. Earned income decreases or ceases, expenses funded by Social Security, pensions, retirement accounts. Investment time horizon can still be long from beginning of retirement.
List some of the major characteristics of each of these life cycle phases. -gifting phase
Assuming a high net worth and more than enough for retirement costs, may begin to give away assets to relatives and charity.
