What is a Drawdown?
What is a Drawdown?
Most investors focus on annual returns, but that misses the reality of markets: your portfolio will regularly lose 10%, 20%, or even 50% of its value. A drawdown is that experience—the decline from a peak to a trough. Understanding drawdowns is foundational to surviving them.
Quick definition: A drawdown is the peak-to-trough decline in a portfolio's value, typically expressed as a percentage. If your portfolio reaches $100,000 and then falls to $70,000, you've experienced a 30% drawdown.
Key Takeaways
- A drawdown measures the decline from the highest point your portfolio reaches to its lowest subsequent point
- Drawdowns are measured from previous peaks, not from entry price or cost basis
- Every portfolio experiences drawdowns; they are a feature of equity markets, not a bug
- Understanding drawdown frequency and magnitude helps you set realistic expectations
- Long-term investors must tolerate temporary losses to capture long-term gains
The Definition: Peak to Trough
A drawdown begins when a portfolio starts declining from its all-time high (the peak) and ends when it stops declining (the trough). The magnitude is the percentage drop from peak to trough. If your $100,000 portfolio falls to $70,000, that's a 30% drawdown. If it falls further to $50,000, that becomes a 50% drawdown—measured always from the original peak.
The key insight: drawdowns reset after recovery. Once your portfolio climbs back to or above the previous peak, the drawdown is over. A new peak is established, and the next drawdown measurement begins from this new level.
Drawdowns vs. Volatility
Novice investors sometimes confuse volatility with drawdowns, but they measure different things. Volatility is the frequency and magnitude of short-term price swings. A portfolio can be highly volatile (moving up and down constantly) yet experience only modest drawdowns if the declines never last long. Conversely, a portfolio can have low volatility but still experience severe drawdowns during prolonged bear markets.
Volatility is noise. Drawdowns are the real cost of equity ownership—the sustained loss that tests your resolve.
Historical Context
The U.S. stock market (S&P 500) has experienced:
- Drawdowns of 10–20% roughly every 3–5 years
- Drawdowns of 20%+ (bear markets) roughly every 7–10 years
- Drawdowns of 50%+ roughly every 20–30 years
These aren't rare. They're the price of admission to equity returns that exceed cash and bonds by 5–7% annually over decades.
Why Drawdowns Matter More Than Returns
A portfolio that gains 100% then loses 50% ends at a 0% net return (100 − 50 = 50, then 50/100 = 50% remaining). This illustrates why the sequence of returns matters and why drawdown recovery is non-linear. To recover from a 50% loss, you don't need a 50% gain—you need a 100% gain to get back to even.
This is not theoretical. During the 2008 financial crisis, the S&P 500 lost 57% from peak to trough. Investors needed a 133% gain to recover. That took until March 2013—more than four years.
Types of Drawdowns
Market-Wide Drawdowns are declines affecting the entire market or major asset classes. These are caused by recession fears, monetary policy shocks, or geopolitical crises. Everyone holding equities experiences them simultaneously.
Company-Specific Drawdowns affect individual stocks due to management failures, earnings misses, or disruption. A stock can plunge 70% while the market declines 15%. Diversification reduces company-specific risk.
Sector Drawdowns hit particular industries—technology in 2022, regional banks in 2023, or energy in 2015. Broad market investors see them as dampened swings in their overall portfolio.
Measuring Your Own Drawdowns
To calculate drawdown in a real portfolio:
- Identify the highest value your portfolio has reached (the peak)
- Track the lowest point it falls to afterward (the trough)
- Calculate: (Trough − Peak) / Peak × 100
Example: Peak of $250,000, trough of $150,000. Drawdown = (150,000 − 250,000) / 250,000 = −40%
If you monitor daily, you'll see drawdowns updating constantly. If the portfolio rises to a new high, the previous drawdown "closes" and a new measurement begins from the new peak.
Real-World Examples
The Dot-Com Crash (2000–2003): The NASDAQ lost 78% from peak to trough. An investor with $100,000 in tech stocks on March 10, 2000, watched it shrink to $22,000. Recovery took 15 years.
The Financial Crisis (2008–2009): The S&P 500 fell 57%. A $500,000 balanced portfolio (60% stocks, 40% bonds) fell to roughly $340,000.
The 2020 COVID Crash: The S&P 500 fell 34% in 23 days (March 2020). However, it recovered to new highs within 5 months—the fastest 30%+ drawdown recovery on record.
The Psychological Reality
Drawdowns hurt not because of the math but because of the feeling. A 30% loss stings more than a 30% gain feels good—this is loss aversion. Your brain treats losses as twice as painful as equivalent gains are pleasant. This asymmetry is why most investors fail at buy-and-hold: they endure the pain of drawdowns but then bail out near the bottom.
Common Mistakes
Mistaking a drawdown for a permanent loss: A 40% decline is painful but temporary if you hold a diversified portfolio of quality companies. Time is the equalizer.
Confusing historical drawdowns with personal risk tolerance: Just because markets have experienced 50% drawdowns doesn't mean your personal portfolio should. Position sizing, asset allocation, and diversification reduce personal drawdown magnitude.
Selling during drawdowns to "avoid further losses": This crystallizes losses and often locks in losses near market bottoms. Recovery is impossible without the recovery.
FAQ
Q: How long does a typical drawdown last? A: Market-wide drawdowns average 9–18 months from peak to recovery. The 2008 crisis took 4+ years. The 2020 COVID crash recovered in 5 months. Outliers exist.
Q: Is a 30% drawdown normal? A: Yes. Expect a 30%+ drawdown roughly every 10 years in a diversified equity portfolio. A 50% drawdown occurs roughly every 20–30 years.
Q: Should I reduce my stock allocation to lower drawdowns? A: Only if your time horizon is short (under 7 years) or if drawdown losses would force you to sell at the bottom. For 20+ year horizons, the opportunity cost of being underinvested usually exceeds the drawdown pain.
Q: How do bonds reduce drawdowns? A: A 60% stock / 40% bond portfolio typically experiences drawdowns 30–40% smaller than an all-stock portfolio. During the 2008 crisis, it fell 25% instead of 57%.
Q: What's the difference between a drawdown and a bear market? A: A drawdown is any peak-to-trough decline. A bear market is conventionally defined as a 20%+ drawdown. A bear market is a severe type of drawdown.
Q: Can I hedge against drawdowns? A: Partially. Bonds, diversification, and some alternative assets reduce drawdown magnitude. But hedging has a cost (lower returns in bull markets). Most long-term investors accept drawdowns rather than pay to hedge them.
Related Concepts
Maximum Drawdown (MDD): The worst peak-to-trough loss a portfolio has experienced historically or could experience. This is critical for risk assessment.
Drawdown Duration: How long a portfolio stays in negative territory from peak. Longer drawdowns test psychological resolve harder than sharp, fast ones.
Recovery Time: The time from trough to return to the previous peak. Some drawdowns recover in months; others take years.
Underwater: A portfolio is "underwater" when it remains below a previous peak—i.e., in drawdown. Investors often feel most pain when underwater longest.
Summary
A drawdown is not a failure of your investment strategy—it's a natural and inevitable feature of equity markets. The S&P 500 has experienced dozens of significant drawdowns over its 100+ year history, yet investors who held through them captured wealth-building returns.
The challenge isn't avoiding drawdowns (impossible) or timing them away (statistically futile). The challenge is understanding them well enough to not panic and sell into them. In the next article, we'll examine why drawdowns are not just inevitable—they're mathematically guaranteed by market structure itself.
