IMC Portfolio Management Principles 2 — Questions and Answers
Question 1: What is the 'Sharpe ratio' and how is it used?
- A measure of a fund's size relative to peers
- A risk-adjusted performance measure showing return per unit of total risk (excess return divided by standard deviation) (Correct answer)
- A measure of bond duration
- A comparison of active versus passive fund returns
Correct answer: A risk-adjusted performance measure showing return per unit of total risk (excess return divided by standard deviation)
The Sharpe ratio = (Portfolio Return - Risk-Free Rate) / Standard Deviation. It measures how much excess return (above the risk-free rate) is achieved per unit of total risk. A higher Sharpe ratio indicates better risk-adjusted performance.
Question 2: What is the 'information ratio' in active fund management?
- The ratio of a manager's research budget to assets under management
- A measure of active return (alpha) per unit of active risk (tracking error) (Correct answer)
- The proportion of investment decisions based on public information
- The ratio of successful to unsuccessful trades
Correct answer: A measure of active return (alpha) per unit of active risk (tracking error)
The information ratio = Active Return / Tracking Error. It measures the consistency of a manager's outperformance relative to their benchmark. A higher information ratio indicates more consistent alpha generation per unit of active risk taken.
Question 3: What is 'passive management' in fund management?
- Management where the manager is not involved in day-to-day decisions
- An investment strategy that replicates a market index rather than selecting securities, aiming to match rather than beat the benchmark (Correct answer)
- Management of low-volatility portfolios only
- Any fund that doesn't use derivatives
Correct answer: An investment strategy that replicates a market index rather than selecting securities, aiming to match rather than beat the benchmark
Passive management (index investing) aims to replicate the performance of a market index by holding its constituent securities in proportion to their index weights. It does not attempt to select securities or time the market, resulting in lower costs than active management.
Question 4: What is the 'investment policy statement' (IPS) and why is it important?
- A regulatory filing required annually by the FCA
- A document outlining a client's investment objectives, risk tolerance, constraints, and guidelines, serving as a mandate for the portfolio manager (Correct answer)
- A fund's annual report to investors
- A statement of investment fees and charges
Correct answer: A document outlining a client's investment objectives, risk tolerance, constraints, and guidelines, serving as a mandate for the portfolio manager
An IPS is a foundational document that defines the client's investment goals, risk tolerance, time horizon, liquidity needs, regulatory constraints, and any special considerations (ethical, tax). It guides all investment decisions and provides a basis for evaluating manager performance.
Question 5: What does 'reversion to the mean' suggest in investment analysis?
- That all returns will eventually become negative
- That returns and valuations that deviate significantly from their long-term average tend to move back towards it over time (Correct answer)
- That fund managers should always invest in mean (average) funds
- That interest rates always return to zero
Correct answer: That returns and valuations that deviate significantly from their long-term average tend to move back towards it over time
Mean reversion is the tendency for asset prices, valuations, and returns that deviate substantially from their long-run average to return toward it. It underpins contrarian investment strategies and suggests current extremes (high or low valuations) are likely temporary.
Question 6: What is 'factor investing' (smart beta)?
- Investing based on macroeconomic factors only
- An investment approach that targets specific return-driving characteristics (factors) such as value, momentum, quality, or low volatility (Correct answer)
- Passive investing in market indices
- Investing in companies with strong management teams only
Correct answer: An investment approach that targets specific return-driving characteristics (factors) such as value, momentum, quality, or low volatility
Factor investing systematically targets exposure to well-documented drivers of return (factors) such as value (cheap stocks), momentum (recent outperformers), quality (profitable stable companies), and size (smaller companies). It sits between pure passive and fully active management.
