Drawdown
What Is a Drawdown? (Short Answer)
A drawdown is the percentage drop from an investment’s peak value to its lowest point before a new peak is reached. It measures the worst loss experienced over a specific period. For example, a fall from $100 to $80 is a 20% drawdown.
If returns tell you how much money you made, drawdown tells you how much pain you had to endure to get there. And in the real world, pain matters. Most investors don’t abandon a strategy because long-term returns look bad on paper - they quit because the drawdown was deeper or longer than they could tolerate.
Key Takeaways
- In one sentence: Drawdown measures the maximum percentage loss from a peak to a trough in an investment or portfolio.
- Why it matters: Deep drawdowns test investor discipline, force bad timing decisions, and can permanently impair capital if you’re leveraged or withdrawing.
- When you’ll encounter it: Portfolio performance reports, hedge fund fact sheets, backtests, risk disclosures, and fund marketing materials.
- Critical insight: Two portfolios can have the same long-term return but wildly different drawdowns - and only one will be psychologically survivable.
- Related metric to watch: Maximum drawdown - the single worst peak-to-trough loss over a period - is often more revealing than volatility.
Drawdown Explained
Drawdown exists because investors don’t experience returns in a straight line. Markets move in fits and starts, and what matters emotionally - and financially - is not the average return, but the largest loss you had to sit through before things recovered.
Historically, drawdown became a core risk metric in professional money management as hedge funds and institutional allocators realized that volatility alone was misleading. A strategy could have low volatility most of the time, then suffer a brutal collapse. Drawdown captures that tail risk in a way standard deviation doesn’t.
Retail investors often think of drawdown as “how much I’m down right now.” Professionals think differently. They focus on maximum drawdown, average drawdown, and drawdown duration - how long it takes to recover. A 20% drawdown that recovers in three months is very different from a 20% drawdown that takes three years.
Institutions use drawdown to size positions, set risk limits, and decide when a strategy is broken versus just out of favor. Analysts use it to compare strategies with similar returns. Companies care about it indirectly because large shareholder drawdowns raise capital costs and invite activist pressure.
Here’s the key mental shift: drawdown is not about predicting the future. It’s about stress-testing your ability to stay invested. If you can’t survive the drawdown, the long-term return is irrelevant.
What Causes a Drawdown?
Drawdowns don’t happen randomly. They’re usually triggered by a small set of repeatable forces. The catalyst changes, but the mechanics are familiar.
- Economic slowdowns and recessions - When growth expectations reset lower, earnings estimates fall, multiples compress, and prices follow. This is how broad, market-wide drawdowns are born.
- Monetary tightening - Rising interest rates increase discount rates and reduce risk appetite. Long-duration assets (growth stocks, tech, crypto) tend to experience the deepest drawdowns.
- Earnings deterioration - Company-specific drawdowns often start when revenue growth stalls or margins crack. The market reprices quickly once confidence breaks.
- Valuation excesses unwinding - Assets priced for perfection don’t need bad news to fall. They just need reality.
- Leverage and forced selling - Margin calls, redemptions, or systematic de-risking can turn normal declines into sharp drawdowns.
- Exogenous shocks - Wars, pandemics, policy surprises. Rare, but when they hit, drawdowns are fast and brutal.
How Drawdown Works
Mechanically, drawdown is simple: you track the highest value reached, then measure how far the price or portfolio falls from that peak. The clock resets only when a new high is achieved.
Drawdown is always expressed as a negative percentage. It doesn’t care how long the decline takes or what caused it - only the distance from peak to trough.
Formula: (Trough Value − Peak Value) ÷ Peak Value
Peak = highest value reached
Trough = lowest value before a new peak
Worked Example
Imagine a $100,000 portfolio. It grows to $120,000. Then the market turns, and the portfolio falls to $90,000 before recovering.
The drawdown isn’t from your original $100,000. It’s from the peak of $120,000.
Calculation: ($90,000 − $120,000) ÷ $120,000 = −25% drawdown.
That number tells you something critical: to get back to breakeven, you now need a 33% gain. Drawdowns are asymmetric - the deeper they get, the harder recovery becomes.
Another Perspective
Now compare two strategies. Strategy A has a −15% maximum drawdown. Strategy B has a −40% drawdown but slightly higher long-term returns.
On paper, B wins. In real life, most investors abandon B at the worst possible time. That’s why drawdown-adjusted returns matter more than headline performance.
Drawdown Examples
Global Financial Crisis (2007–2009): The S&P 500 suffered a maximum drawdown of roughly −57%. Many investors who sold near the bottom missed one of the strongest bull markets in history.
COVID Crash (Feb–Mar 2020): The S&P 500 fell about −34% in just over a month. The speed was unprecedented, but the recovery was equally fast.
NASDAQ 2000–2002: Tech-heavy portfolios experienced drawdowns exceeding −75%. It took over a decade for the index to reclaim its highs.
Individual stock example: Meta (Facebook) fell roughly −76% from its 2021 peak to its 2022 trough as growth slowed and valuations reset.
Drawdown vs Volatility
| Aspect | Drawdown | Volatility |
|---|---|---|
| What it measures | Peak-to-trough loss | Price variability |
| Direction-sensitive | Yes (loss-focused) | No (up and down) |
| Investor relevance | Psychological & capital risk | Statistical risk |
| Common use | Risk limits, stress testing | Portfolio construction |
Volatility tells you how bumpy the ride is. Drawdown tells you how bad the worst crash was. Investors live with drawdowns; risk models live with volatility.
If you care about staying invested - and you should - drawdown is the more honest metric.
Drawdown in Practice
Professional investors bake drawdown limits into their process. A hedge fund might cap acceptable drawdown at −20%. Breach that, and risk is cut automatically.
Long-term allocators compare strategies on return per unit of drawdown. A smoother path compounds better because capital stays invested.
Certain sectors - commodities, crypto, small caps - are drawdown-prone by nature. That doesn’t make them uninvestable, but it demands smaller position sizes and stronger stomachs.
What to Actually Do
- Size positions assuming the worst drawdown will repeat. If a stock historically drops 40%, don’t size it like a bond.
- Match drawdown to time horizon. Deep drawdowns are tolerable only if you have years, not months.
- Use drawdown to set rules, not emotions. Decide in advance what level triggers a rebalance or review.
- Respect recovery math. Losses over 30% require outsized gains to recover - avoid digging that hole.
- When NOT to act: Don’t sell solely because you’re in a drawdown. Sell because the thesis is broken.
Common Mistakes and Misconceptions
- “Drawdowns mean the strategy failed.” No - all strategies have drawdowns. The question is magnitude and duration.
- “It’ll come back because it always has.” Not always. Some drawdowns are permanent.
- “Volatility and drawdown are the same.” They measure different risks. One is noise; the other is damage.
- “I’ll know when the bottom is in.” You won’t. Manage risk instead.
Benefits and Limitations

- Useful for comparing strategies
- Improves position sizing discipline
- Aligns risk with psychology
Limitations:
- Backward-looking by definition
- Depends heavily on time window

- Can understate slow, grinding declines
- Not predictive on its own
Frequently Asked Questions
Is a drawdown a good time to invest?
Sometimes. Shallow drawdowns can be noise; deep drawdowns can be opportunity or value traps. The difference is fundamentals.
How often do drawdowns happen?
Small drawdowns happen yearly. Large ones (20%+) occur roughly once a decade in equities.
How long do drawdowns last?
Anywhere from weeks to years. Duration matters as much as depth.
What’s the difference between drawdown and a bear market?
A bear market is a market-wide decline of 20%+. Drawdown applies to any asset or portfolio.
What should I do during a drawdown?
Revisit your thesis, rebalance if planned, and avoid emotional decisions.
The Bottom Line
Drawdown is the price of admission for long-term returns. You can’t eliminate it, but you can decide in advance how much you’re willing to endure. The best investors don’t avoid drawdowns - they design portfolios that survive them.
