A written global allocation plan: EM share, country caps and review triggers

What you will learn

• How to set an emerging-market (EM) share with a stated reason and a tolerance you can live with.
• How to translate country caps and vehicle limits into euro amounts.
• How to define rebalancing bands and event-based review triggers for global holdings.
• How to write the plan on one page so that you can check it in ten minutes a quarter.

Explanation

A general investment policy is covered in the course "ETFs, Funds & Long-Term Investing", and sizing rules for factors and alternatives are covered in their own courses. This lesson adds the global and EM-specific part. A good global allocation plan has six sections.

1. EM share and its reason

State the EM share of your equities as a number and give the reason in one sentence, for example "15 % of equities, between the market-cap weight of about 12 % and a modest valuation tilt, because I want diversification without a currency exposure I cannot hold through a weak decade". Write the worst case in euros using a 50 to 60 % drawdown, which EM indices have experienced historically, and confirm you would not sell there.

2. Country and issuer caps

A broad EM ETF already has a cap built in by the UCITS rules: an index-tracking UCITS fund may hold up to 20 % in a single issuer, 35 % in exceptional market conditions. But countries are not capped. Set your own: for example, no single EM country above 30 % of your EM holdings or 4 % of your total portfolio, counting broad funds, single-country funds and direct shares together. Look through funds: a China fund on top of a broad EM ETF can double the China weight unnoticed.

3. Vehicle rules

Decide in advance which instruments you use: index family (one family only, as explained in the ETF lesson), accumulating or distributing, whether you accept synthetic replication, maximum share of closed-end or single-country funds, and whether EM bonds count as equity risk or bond risk in your allocation (most planners treat hard-currency EM debt as closer to equity risk in a crisis).

4. Rebalancing bands

Use relative bands: review when the EM share drifts more than 25 % away from target (for a 15 % target, below 11.25 % or above 18.75 %), or at a fixed date once a year, whichever comes first. Relative bands prevent a small position from quietly shrinking after a bad run.

5. Event triggers

List events that require a review within a set time regardless of weights: an index reclassification announcement for a country above your cap, sanctions or capital controls affecting a holding, a fund closing or changing index, a withholding-tax change in a major country (Brazil's 2026 dividend tax is an example), and a change in your own circumstances such as moving country or retiring.

6. What you will not do

Write a short list of actions you forbid yourself: no new country fund without a written thesis, no leverage on EM positions, no selling the EM block entirely after a drawdown. Leverage, CFDs and futures on volatile EM indices can lose money very quickly; this plan assumes unleveraged holdings.

Worked example

Hypothetical example: a €100,000 portfolio with a 70 % equity target. All numbers are invented; taxes, fees and currency moves are excluded.

Step 1 – amounts. Equities = 0.70 × 100,000 = €70,000. EM share 15 % of equities = 0.15 × 70,000 = €10,500. Developed equities = €59,500.

Step 2 – country cap. Cap: no country above 30 % of EM. 0.30 × 10,500 = €3,150, which is 3.15 % of the total portfolio. If the broad EM index holds China at 28 %, a single China fund of any size would break the cap.

Step 3 – bands. Target 15 % of equities, relative band ±25 %: lower limit 11.25 %, upper limit 18.75 %. In euros at today's equity value: €7,875 to €13,125.

Step 4 – a drift test. Suppose EM falls 30 % and developed markets rise 10 %. EM = 10,500 × 0.70 = €7,350; developed = 59,500 × 1.10 = €65,450. EM share = 7,350 ÷ (7,350 + 65,450) = 10.1 %. Below 11.25 %, so the plan calls for buying EM back towards 15 % with new savings or by trimming developed holdings, after checking that no event trigger explains the fall.

Step 5 – worst case in euros. A 55 % EM drawdown on €10,500 is a loss of €5,775, 5.8 % of the portfolio. The investor confirms in writing that this is acceptable.

Common mistake

Practice activity

On paper: a €250,000 portfolio with an 80 % equity target and a 20 % EM share of equities. Your rule: no single EM country above 25 % of EM holdings. Your broad EM ETF holds India at 22 %, and you also own a single-country India fund worth €8,000. (a) Calculate the EM amount and the India cap in euros. (b) Calculate your total India exposure and the amount above the cap. (c) Name two event triggers from this lesson that would force a review of this position even if the weights were within limits.

Key takeaways

• State the EM share, its reason and its euro worst case; if you would sell at the worst case, the share is too high.
• Cap countries across all routes (broad funds, country funds, direct shares) and look through funds once a year.
• Use relative rebalancing bands plus a fixed annual date, and keep a list of event triggers that override the calendar.
• Write what you will not do: no leverage, no unplanned country bets, no abandoning the plan after a drawdown.
