Maximum Drawdown (MDD)

Definition

Maximum Drawdown (MDD) is defined as the maximum observed loss in the value of a portfolio from its highest point (peak) to its lowest point (trough) before it reaches a new peak. This metric is essential for understanding downside risk over a specific time period and can be used independently or as an input for other performance metrics such as “Return over Maximum Drawdown.”

Formula for Maximum Drawdown

To calculate MDD, use the following formula:

\[ \text{MDD} = \frac{\text{Trough Value} - \text{Peak Value}}{\text{Peak Value}} \times 100 \]

Comparison: Maximum Drawdown (MDD) vs. Standard Deviation

Example

Suppose you had an investment portfolio that reached a peak value of $100,000 and then experienced a decline to a trough of $70,000 before recovering again.

Using the formula: \[ \text{MDD} = \frac{70,000 - 100,000}{100,000} \times 100 = -30% \]

This means that your portfolio experienced a maximum drawdown of 30%.

Fun Facts

• Historical studies have shown that the average maximum drawdown for stock markets is around 50%, which means if you had bought at the peak, you might end up doing the “drawdown dance!”

Frequently Asked Questions

1. What does MDD tell me about my investment?

   • MDD gives insight into how much you might lose in a downturn, which can help in planning your investment strategy accordingly.

2. How can I reduce the maximum drawdown in my portfolio?

   • Diversification, stop-loss orders, and choosing less volatile investments can help manage MDD.

3. Should I only focus on MDD when evaluating investments?

   • While MDD is important, it should be considered along with other metrics such as returns and volatility.

4. Why is MDD expressed as a percentage?

   • Expressing MDD as a percentage allows investors to assess loss relative to their investment, making it easier to compare risks across different portfolios.

5. Is a lower MDD always better?

   • Not necessarily. A lower MDD may indicate less risk, but it could also mean fewer opportunities for significant returns.
