Capital market expectations sit at the very heart of the portfolio management process — they are the bridge between an investor's policy (the IPS) and the actual portfolio that gets constructed.
**Where CMEs Fit in the Process:**
The portfolio management workflow follows a logical chain:
1. **Investment Policy Statement (IPS)** — defines objectives (return requirements, risk tolerance) and constraints (time horizon, liquidity, taxes, legal, unique)
2. **Capital Market Expectations** — forecasts of expected return, risk, and correlations for each permissible asset class
3. **Strategic Asset Allocation** — combines the IPS constraints with CMEs to determine the long-term policy mix
4. **Implementation** — security selection and portfolio construction within each asset class
5. **Monitoring and Rebalancing** — ongoing review and adjustment
CMEs are the critical Step 2 input. Without them, you literally cannot perform Step 3 — strategic asset allocation requires quantitative estimates of expected returns, volatilities, and correlations for every asset class in your opportunity set.
**Why You Can't Skip CMEs:**
Imagine a pension fund whose IPS permits eight asset classes: domestic equities, international developed equities, emerging market equities, domestic government bonds, domestic corporate bonds, real estate, commodities, and cash. To determine the optimal mix, the fund needs:
- 8 expected return estimates
- 8 volatility estimates
- 28 pairwise correlation estimates (8 choose 2)
- That's 44 quantitative inputs, all of which are CMEs
If any of these inputs are materially wrong, the resulting allocation will be suboptimal — potentially dangerously so. This is why the CFA curriculum devotes two full readings to CME setting before even discussing allocation techniques.
**Long-Term vs. Short-Term CMEs:**
- **Long-term CMEs** drive strategic asset allocation — the baseline policy portfolio. These are typically 5–20 year projections anchored to fundamental economic drivers.
- **Short-term CMEs** support tactical asset allocation — temporary deviations from the strategic mix to exploit perceived mispricings. These are 6–18 month views.
**The Insight:** CMEs also inform security selection. The macro analysis you perform when setting asset class expectations reveals insights about which sectors, industries, or securities within an asset class are likely to benefit from your macro view.
