Multi-Asset Portfolio Management

At this level, the question shifts from "is this a good trade?" to "is this a good addition to my portfolio?" Multi-asset portfolio management treats all your positions — across currencies, indices, commodities, and crypto — as one book with one risk budget. It's how professional money managers think, and it draws on every risk lesson in Tiers 1–5.

What you'll learn

• Thinking in portfolios instead of individual trades
• Risk budgeting across asset classes and strategies
• Volatility-based sizing so each position contributes comparable risk
• Correlation-aware allocation and rebalancing
• Portfolio-level drawdown control

1. Thinking in portfolios

A single trade is judged by its setup. A portfolio is judged by how positions work together:

• Do they share a hidden driver (see Portfolio-level risk)?
• Does the portfolio still make sense if one theme fails?
• Is risk spread across independent sources of return?

2. Risk budgeting

Decide how much total risk you'll run, then allocate it deliberately.

(Illustrative risk budget for a $100,000 portfolio.)

The budget forces choices. When a new opportunity appears and the relevant bucket is full, you either skip it or replace a weaker position.

3. Volatility-based sizing

Assets have very different volatility. A 1% move in EUR/USD is large; in Bitcoin it's routine. Sizing every position at the same notional amount means the most volatile assets dominate your risk.

Volatility-based sizing sets each position so it contributes similar risk — typically using ATR or a similar volatility measure to set stops, then sizing each from the same risk amount (see Volume and volatility indicators).

Worked example

(Illustrative. Risk per position $400.)

Each position risks the same $400, even though their notional sizes and volatility differ enormously. The MES line also shows a real constraint: sometimes the minimum contract size is too large for the budget.

4. Correlation-aware allocation and rebalancing

• Allocate across low-correlation sources: for example, trend-following in commodities and mean-reversion in equity indices.
• Recheck correlations monthly over a recent window (see Correlation across your market and adjacent markets).
• Rebalance risk, not just capital: as positions move, their risk changes (especially after trailing stops or big volatility shifts). Review and resize periodically.

5. Portfolio-level drawdown control

Apply the tiered drawdown plan (see Drawdown control and equity curve management) to the whole portfolio:

• Measure drawdown on total equity, not per position.
• Reduce the overall risk budget at thresholds (for example, cut the maximum total open risk from 4% to 2% at a 6% portfolio drawdown).
• Reduce first where evidence is weakest — strategies below their benchmarks.

Who it suits

Common beginner mistakes

• Equal notional sizing across assets with very different volatility.
• Diversifying on paper while holding one hidden theme.
• No overall risk budget.
• Ignoring rebalancing as positions and volatility change.
• Measuring drawdown per trade instead of for the portfolio.

Key terms

Practice

1. Write a risk budget for your account: total, per asset class, per theme, per strategy.
2. Size three positions in different asset classes with the same risk amount, using ATR-based stops.
3. Run a simple risk-off stress test on your current or hypothetical portfolio.
4. Add portfolio-level drawdown thresholds to your trading plan.

Quick recap

• Judge positions by how they fit the portfolio.
• Set a risk budget by asset class, theme, and strategy.
• Use volatility-based sizing so each position contributes comparable risk.
• Allocate across low-correlation sources and rebalance risk regularly.
• Control drawdown at the portfolio level.
