Portfolio Risk Management: Diversification and Correlation

Portfolio Risk Management: Diversification and Correlation

Most traders treat each trade independently. Professional traders manage portfolio risk: how all positions correlate and interact. This guide teaches you portfolio-level risk management.

Concentration Risk

If you have 5 long positions on crypto correlated pairs (BTC, ETH, ADA), one market event liquidates all of them together. This is concentration risk.

Better approach: Mix long and short positions, different asset classes (crypto, forex, commodities), different correlations.

Correlation Matrix

Correlation ranges from -1 (perfect opposite moves) to +1 (perfect same moves).

BTC and ETH: Correlation ~0.9 (move together)

BTC and Gold: Correlation ~-0.2 (often opposite)

Long-short mix: Correlation ~0 (hedged)

Build a portfolio with mixed correlations for stability.

Maximum Drawdown Planning at Portfolio Level

If each position risks 1% and you have 5 positions: Maximum loss = 5%. If worst case, all 5 lose at once, you're down 5%.

If you have 10 positions at 1% each: Maximum loss = 10%. But if only 50% lose in the worst month (typical), you lose 5%.

More positions = more likely some win while others lose (portfolio stability).

The Ideal Portfolio Mix

- 60% in your highest-conviction setups (win-rate 65%+)

- 30% in good setups (win-rate 55-60%)

- 10% in speculative/learning setups (win-rate unknown)

This mix balances high-probability wins with diversification.

Action Plan

List all your open positions right now. Calculate: What if all correlate 0.9+ (move together)? What if market gaps against all of them overnight? If you can't survive that scenario, reduce concentration.
