Overview of Risk Measurement
- →Distinguish risk management from risk measurement
- →Understand what the investment policy statement (IPS) contains
- →Identify the five components of risk measurement
- →Understand risk measurement at the position level and valuation approaches
- →Understand how data collection frequency affects risk measurement
Risk Management vs. Risk Measurement; The IPS; Five Components
- Risk management — decisions and actions associated with overseeing and controlling exposure to uncertainty.
- Risk measurement — all steps involved in gathering and reporting information to capture an investor's exposure to uncertainty.
Risk management starts with risk measurement; risk measurement starts with the performance reporting process.
Investment Policy Statement (IPS) — the top-level document governing risk:
- Describes investor's financial goals, objectives, circumstances, and constraints
- Contains investment mandates for the portfolio
- Provides the context for all risk measurement and management
- Risk is developed top-down (from IPS → asset class → strategy → geography → sector → position)
- Aggregated bottom-up (from each position up through each level to portfolio total)
Five Components of Risk Measurement (the five interrogatives):
| # | Component | Interrogative | Description |
|---|---|---|---|
| 1 | Investment/Position Level | Where | Design data collection approach per investment |
| 2 | Frequency of Data Collection | When | Daily, weekly, monthly, quarterly, annual |
| 3 | Aggregation & Systems Development | How | Systematised, repeatable risk process |
| 4 | Dimensions of Risk | What | All risks associated with each investment |
| 5 | Risk Reporting | Whom | For whom the risk data is collected and acted upon |
Five Components of Risk Measurement
| # | Component | Interrogative | Key focus |
|---|---|---|---|
| 1 | Investment/Position Level | Where | Data collection design per position |
| 2 | Frequency of Collection | When | Daily → annual; linked to investment liquidity |
| 3 | Aggregation & Systems | How | Systematised, repeatable, automated process |
| 4 | Dimensions of Risk | What | All quantitative and qualitative risks |
| 5 | Risk Reporting | Whom | Tailored to each level of decision-maker |
Check Your Understanding
A risk officer asks: "How often should we collect return data, and should it differ by investment type?" Which of the five components of risk measurement does this question address?
Valuation at Position Level; Data Collection Frequency
Risk measurement at the position level includes:
- Amount invested, valuation, long or short position
- For fixed income and OTC derivatives: rates, tenor, early redemption, optionality, key covenants, exercise terms, extraordinary features
Valuation confidence hierarchy:
- Level 1: Highly liquid, exchange-traded; prices accepted with high confidence
- Level 2: Can be valued using observable inputs
- Level 3: Illiquid; model-based values with relatively low confidence
Three methods for illiquid asset interim valuations:
- Capital statement valuations — quarterly statements from sponsoring manager; used as basis for interim estimates
- DCF model-based calculations — defined parameters (growth rate, discount rate, expected exit value) for interim periods
- Customized index — proxy using comparable public securities with an illiquidity discount ("haircut")
Valuation policy — crafted by back office; approved by operating and investment committees; summarised in a pricing matrix (asset type × valuation approach).
-
Industry best practice: all valuation activities within back office only (avoids conflict of interest from investment team involvement)
-
Exception report — filters data to show only instances where risk measures are outside predetermined bands; used to optimise efficiency and focus senior management attention.
Key frequency principle: Higher data collection frequency → less time between valuations, better exception reporting, earlier detection of style drift or risk increases. However, illiquid alternatives (private equity, hedge funds) naturally arrive with new information only quarterly or annually.
Exhibit 1 — Data Collection Frequency Summary:
- Daily: Values, returns, position size, volume, benchmark data, keyword alerts → Values, performance, risks, exceptions
- Weekly: No additional data → Exposures, netted exposures, changes in exposures
- Monthly: Position/manager changes; non-investment qualitative risks → Turnover, exposures, cash, illiquid positions
- Quarterly: Manager calls and reports; illiquid position valuations → Manager call summaries, illiquid position info
- Annually: Site visits, annual audits, reference updates → Reports, summaries, manager analyses
Data Collection Frequency — What Changes at Each Level
| Frequency | Additional data collected | Key reporting outputs |
|---|---|---|
| Daily | Values, returns, positions, volume, benchmarks, keyword alerts | Performance, risks, exceptions, events |
| Weekly | No new data beyond daily | Exposures, changes in exposures |
| Monthly | Position/manager changes; qualitative risks (legal, regulatory) | Turnover, top positions, cash, illiquid positions |
| Quarterly | Extensive manager calls; illiquid valuations | Manager call summaries; illiquid position info |
| Annually | Site visits, annual audits, reference updates | Full re-underwriting reports, manager analyses |
