Drawdown(回撤)

A drawdown measures the peak-to-trough decline of an investment from its highest value. It tells you how much you could lose from the top — and how long it takes to recover.

Formula

Drawdown % = (Trough Value − Peak Value) ÷ Peak Value × 100

Recovery requires a larger gain than the loss: a 50% drawdown needs a 100% gain to break even.

Example

Your portfolio reaches a peak of $100,000, then declines to $70,000 during a market downturn. The drawdown is ($70,000 − $100,000) ÷ $100,000 = −30%, or a 30% drawdown. To recover, your portfolio must gain 42.9% ($70,000 → $100,000), not just 30%.

Why It Matters

Drawdown is the most psychologically important risk metric because it reflects the actual pain investors experience. While standard deviation measures volatility in the abstract, drawdown answers the visceral question: "How much did I actually lose from my highest point?" A 50% drawdown doesn't just halve your wealth — it shakes your confidence, tempts you to sell at the bottom, and takes years to recover. Studies show that investors who experience drawdowns exceeding 25% are significantly more likely to abandon their investment strategy.

The mathematics of recovery are asymmetric and brutal. After a 30% loss, you need a 43% gain to break even. After a 50% loss, you need to double your money. After an 80% loss — which many tech stocks experienced in 2000-2002 — you need a 5x return. This asymmetry is why professional risk management focuses on limiting drawdowns rather than maximizing returns. A strategy that makes 20% annually with 50% drawdowns is far worse than one making 12% with 15% drawdowns, because the former's recovery periods destroy compounding.

Real-World Example

Tesla (TSLA) is a textbook example of extreme drawdowns. In 2022, Tesla stock fell from its November 2021 peak of approximately $414 to around $101 in January 2023 — a drawdown of roughly 75%. Investors who bought near the peak needed Tesla to triple from the bottom just to break even. By mid-2025, Tesla recovered to above $300 but still hadn't fully reclaimed its all-time high.

Compare this with Microsoft (MSFT), which experienced a maximum drawdown of about 37% during the same 2022 period (from ~$370 to ~$213). Microsoft recovered to new all-time highs by early 2024. The difference illustrates why drawdown management matters: smaller drawdowns recover faster, allowing compounding to resume sooner. This is why many institutional investors cap maximum drawdown at 15-20% — beyond that, the math of recovery becomes too punishing.

Common Mistakes

Pro Tips

Set a personal "circuit breaker": Before investing, define your maximum tolerable drawdown (e.g., 20%). If your portfolio hits that level, automatically reduce equity exposure by 30-50%. This removes emotional decision-making during crashes.

Track drawdown duration, not just depth: The S&P 500's 2000-2002 drawdown lasted 2.5 years, and recovery took another 4 years. The 2020 COVID drawdown was 34% but recovered in just 5 months. Short, deep drawdowns are far less damaging than prolonged shallow ones because of opportunity cost.

Frequently Asked Questions

What is maximum drawdown?

Maximum drawdown is the largest peak-to-trough decline in your portfolio. If your portfolio grew to $100K then dropped to $70K before recovering, your max drawdown is 30%. This is the worst-case scenario you experienced. Risk-averse investors should target max drawdown below 20% — anything above causes sleepless nights.

How long does recovery from drawdown take?

A 10% drop needs 11% gain to recover. A 30% drop needs 43% gain. A 50% drop needs 100% gain. This exponential relationship is why controlling drawdown is so important. The S&P 500 took 5.5 years to recover from the 2008 crash (57% drawdown) and about 5 months to recover from the 2020 crash (34% drawdown).

How can I reduce portfolio drawdown?

Diversify across asset classes (stocks, bonds, gold), maintain cash reserves, use stop-losses on individual positions, and consider protective options strategies during uncertain times. The simplest approach: increase bond allocation. A 60/40 portfolio historically has about half the max drawdown of a 100% stock portfolio.
