When to use this
- Understanding what factors and themes your portfolio is exposed to
- Finding correlated risks across positions
- Stress-testing your holdings against a scenario
- Getting a clear picture of your real risk, not just position sizes
Step 1: Map your exposures
Step 2: Find correlated risk
The key insight is correlation, not just size:Step 3: Stress-test a scenario
Step 4: Decide whether to adjust
Common mistakes
- Equating position size with risk. A small position in a volatile, correlated name can carry more risk than a large position in a stable one.
- Missing the common thread. Diversification by name is not diversification by risk. Look for the shared driver.
- Stress-testing only the obvious. Test the scenario you are not worried about, not just the one you are.
