CIMA - Certified Investment Management Analyst Portfolio Theory and Construction Questions and Answers

Question 1

An investment advisor is constructing a portfolio for a client. According to Modern Portfolio Theory (MPT), which of the following portfolios is considered 'efficient'?

Accepted Answer

A portfolio that provides the highest possible return for any given level of risk.

Answer

Modern Portfolio Theory (MPT) defines an efficient portfolio as one that offers the highest expected return for a given level of risk (measured by standard deviation). Portfolios on the efficient frontier represent this optimal trade-off. A portfolio of only the highest-returning assets would likely have unacceptably high risk. No portfolio can guarantee positive returns, and investing only in government securities would likely not provide the highest possible return for its low level of risk.

Question 2

An analyst is evaluating a portfolio that lies below the Capital Market Line (CML). What does this position signify?

Accepted Answer

The portfolio is inefficient, offering a suboptimal risk-return trade-off.

Answer

The Capital Market Line (CML) represents the risk-return combinations of all efficient portfolios formed by combining a risk-free asset and the market portfolio. Any portfolio that plots below the CML is considered inefficient because it offers a lower return for the same level of risk (standard deviation) as a portfolio on the CML, or conversely, it has higher risk for the same level of return.

Question 3

A portfolio manager makes short-term adjustments to a client's asset allocation to capitalize on expected market outperformance in the technology sector. This is an example of which portfolio management strategy?

Accepted Answer

Tactical Asset Allocation

Answer

Tactical Asset Allocation (TAA) is a dynamic strategy that involves making short-term, active adjustments to a portfolio's strategic asset allocation to capitalize on perceived market opportunities or to mitigate risks. This contrasts with Strategic Asset Allocation, which is a long-term, target-based approach.

Question 4

In the context of the Capital Asset Pricing Model (CAPM), which of the following lines graphically represents the expected return of all assets and portfolios in the market, based on their systematic risk (beta)?

Accepted Answer

Security Market Line (SML)

Answer

The Security Market Line (SML) is a graphical representation of the CAPM, plotting the expected return of an asset or portfolio against its systematic risk, which is measured by beta. The CAL shows the risk-return trade-off for a specific risky portfolio and a risk-free asset, while the CML is a special case of the CAL using the market portfolio. The efficient frontier shows optimal portfolios based on total risk (standard deviation), not systematic risk.

Question 5

A CIMA professional is using an optimization model that generates a series of 'corner portfolios'. What is the primary significance of these corner portfolios in portfolio construction?

Accepted Answer

Any other efficient portfolio on the frontier can be created by combining two adjacent corner portfolios.

Answer

Corner portfolios are specific portfolios on the efficient frontier identified by optimizers. Their key characteristic is that any other optimal portfolio located on the efficient frontier between two corner portfolios can be constructed as a linear combination (a weighted average) of those two adjacent corner portfolios. This simplifies the process of identifying all possible efficient portfolios.
