A drawdown is the decline in an investment's value from its peak (highest point) to its trough (lowest point) before a new peak is reached. It measures how much an investment falls during a losing period and is one of the most important metrics for understanding investment risk.
While returns tell you how much you have gained, drawdown tells you how much pain you might have to endure along the way. Even investments with excellent long-term returns can experience significant drawdowns that test investor resolve.
Formula: Drawdown = (Peak Value - Trough Value) / Peak Value × 100
Example: Your portfolio reaches $100,000, then drops to $75,000 before recovering
The mountain hike analogy
Imagine hiking up a mountain. Your overall journey takes you from sea level to 3,000 meters. But along the way, you might descend into valleys where you drop 500 meters before climbing again. The drawdown is like measuring how deep those valleys are. Even though you reach the summit eventually, those valleys can be exhausting and discouraging.
Drawdown is psychologically and financially important for several reasons:
Large drawdowns can cause investors to panic and sell at the worst time. Studies show that the pain of losing money is roughly twice as powerful as the pleasure of gaining the same amount. A 30% drawdown feels much worse than a 30% gain feels good.
Recovering from a drawdown requires a larger percentage gain than the percentage lost:
| Drawdown | Return Needed to Recover |
|---|---|
| 10% | 11.1% |
| 20% | 25.0% |
| 30% | 42.9% |
| 40% | 66.7% |
| 50% | 100.0% |
| 60% | 150.0% |
The recovery math is brutal
If your portfolio drops 50%, you need a 100% gain just to break even. This is why avoiding large drawdowns is often more important than chasing high returns. An investment that gains 8% per year with small drawdowns often outperforms one that gains 12% but experiences 40% drawdowns.
Understanding historical drawdowns helps set expectations:
| Event | Period | Drawdown | Recovery Time |
|---|---|---|---|
| Great Depression | 1929-1932 | -86% | 25 years |
| Oil Crisis | 1973-1974 | -48% | 7.5 years |
| Dot-com Crash | 2000-2002 | -49% | 7 years |
| Financial Crisis | 2007-2009 | -57% | 5.5 years |
| COVID Crash | 2020 | -34% | 5 months |
| 2022 Bear Market | 2022 | -25% | 2 years |
The maximum drawdown is the largest peak-to-trough decline over an investment's entire history. It represents the worst-case scenario an investor would have experienced.
When evaluating investments, always check the maximum drawdown. A fund might advertise 15% annual returns, but if its maximum drawdown was 60%, many investors would have sold in panic during that period and missed the recovery.
Compare investments not just by returns, but by returns relative to drawdowns:
Investment A might be preferable because the extra 2% return in B does not compensate for the nearly 3x higher drawdown.
Understanding drawdown helps with:
A useful metric that incorporates drawdown:
Calmar Ratio = Annualized Return / Maximum Drawdown
Higher is better. A ratio above 0.5 is decent; above 1.0 is excellent.
Spreading investments across different assets reduces drawdowns because they rarely all decline simultaneously.
Including bonds and other less volatile assets limits overall portfolio drawdown:
| Portfolio | Expected Return | Typical Max Drawdown |
|---|---|---|
| 100% Stocks | 10% | 50%+ |
| 80% Stocks / 20% Bonds | 9% | 35-40% |
| 60% Stocks / 40% Bonds | 8% | 25-30% |
| 40% Stocks / 60% Bonds | 6-7% | 15-20% |
Some investors use predetermined exit points to limit drawdowns, though this can result in selling low and missing recoveries.
Continuing to invest during drawdowns means buying at lower prices, which can accelerate recovery.
The silver lining of drawdowns
While painful, drawdowns present opportunities. Investors who continued buying during the 2008 financial crisis or the 2020 COVID crash saw exceptional returns in subsequent years. If you have a long time horizon and stable income, drawdowns are opportunities to buy quality investments at discounted prices.
Before investing, honestly assess your risk tolerance:
If you would panic and sell during a 30% drawdown, you should not hold a 100% stock portfolio, regardless of the long-term return potential.
