What Is Understanding Portfolio Drawdowns?
A portfolio drawdown measures the peak-to-trough decline in portfolio value. Maximum drawdown captures the worst historical decline, while average drawdown provides a more typical expectation. Recovery time — how long to return to the peak — is equally important for planning.
Why It Matters
Drawdowns of 20% or more are psychologically difficult for most investors and often trigger panic selling at the worst possible time. Understanding your portfolio's expected drawdown range before it happens helps maintain discipline during market stress.
How LyraIQ Approaches This
LyraIQ computes heuristic drawdown estimates based on current portfolio volatility, concentration, and regime context. The system provides probabilistic framing: 'Based on current conditions, a 15-20% drawdown would be expected in a severe correction, with 8-12 months typical recovery time.'
Practical Steps
- Calculate maximum drawdown using historical portfolio returns
- Estimate recovery time from past drawdown episodes
- Set a personal maximum drawdown threshold for risk management
- Build a cash reserve equal to 6-12 months of expected maximum drawdown
- Document a re-entry plan for adding equity exposure after significant drawdowns
