Drawdown Definition & Formula
In investing, a drawdown quantifies the decline from a peak price to the current price. Unlike a simple price change that compares today's price to yesterday's, a drawdown always references the highest point the asset has ever reached — its all-time high.
Formula
Drawdown % = ((Current Price − All‑Time High) / All‑Time High) × 100
The result is always zero or negative. A drawdown of 0% means the asset is trading at its all-time high. A drawdown of −50% means the asset has lost half its value from the peak.
Drawdown Example
Suppose you're watching a stock that reached an all-time high of $100 and is now trading at $75:
Drawdown % = (($75 − $100) / $100) × 100
Drawdown % = (−$25 / $100) × 100
Drawdown % = −25%
The stock is in a 25% drawdown from its all-time high.
This tells you the stock is 25% cheaper than its best-ever price. Whether that represents a buying opportunity depends on why the stock declined and whether the drawdown is unusual for that particular asset. A 25% drawdown is routine for a volatile stock like Tesla (TSLA) but extremely rare for a stable stock like Microsoft (MSFT).
Drawdowns vs Corrections vs Bear Markets
These terms are often confused, but they describe different things. Here's how they compare:
| Term | Definition | Threshold | Scope |
|---|---|---|---|
| Drawdown | Decline from all-time high | Any size | Individual asset |
| Correction | Decline from recent peak | 10–20% | Market-wide |
| Bear Market | Sustained decline | 20%+ | Market-wide |
The key distinction: drawdowns apply to any individual asset and have no minimum threshold. A stock in a 3% drawdown is simply 3% below its all-time high. Corrections and bear markets are terms reserved for broader market declines of specific magnitudes.
This makes drawdowns the most versatile and precise measurement for individual stock monitoring. You can track the drawdown of any asset — a single stock, an ETF like the S&P 500 (SPY), or a cryptocurrency like Bitcoin (BTC) — at any given moment.
Why Drawdowns Matter for Investors
Tracking drawdowns helps investors move beyond emotional decision-making and toward data-driven buying. When a quality stock you've been watching enters a significant drawdown, it may represent a buying opportunity — the same business at a lower price. This is the foundation of the buy-the-dip strategy.
However, not every drawdown is meaningful. A volatile stock might routinely experience 20–30% drawdowns as part of its normal trading pattern, while the same drawdown for a stable blue-chip stock would be historically rare. Context matters. The raw drawdown percentage only tells part of the story — you also need to know how unusual that drawdown is for that particular asset.
This is why experienced investors compare the current drawdown against historical drawdown patterns for each stock. A drawdown that is 2–3 times larger than a stock's typical pullback is far more noteworthy than one that falls within normal volatility. Understanding this distinction is what separates opportunistic buying from catching a falling knife.
How DrawdownAlerts Measures Drawdowns
At DrawdownAlerts, we go beyond the simple drawdown percentage. Our proprietary Drawdown Severity Score analyzes up to 40 years of historical data for each asset to determine how unusual the current drawdown is relative to that stock's own history.
The Drawdown Severity Score answers one question:
"Is this a routine dip, or a rare opportunity?"
A severity of 1x is an average pullback. A severity of 5x+ means the stock is experiencing a drawdown 5 times deeper than its typical dip — a statistically rare event. Learn more about how the score works.
You can view current drawdown data and severity scores for thousands of assets on the Explore page, or check any individual ticker like AAPL or GOOGL for detailed drawdown history.
Frequently Asked Questions
How long do stock drawdowns typically last?
The duration varies widely depending on the severity and cause. Minor drawdowns of 5–10% for individual stocks often recover within weeks to a few months. Moderate drawdowns of 10–20% can take several months to over a year. Major drawdowns of 30%+ (such as during the 2008 financial crisis or 2020 COVID crash) can take 1–3 years or longer for a full recovery to new all-time highs. You can explore historical drawdown timelines on our market drawdowns page.
What is a normal drawdown for stocks?
A "normal" drawdown depends on the individual asset. Low-volatility blue-chip stocks may typically experience drawdowns of 10–20% during routine pullbacks, while high-volatility stocks regularly see drawdowns of 30–50%. For the S&P 500 index, drawdowns of 5–10% happen roughly once or twice per year and are considered routine. Drawdowns exceeding 20% are less common and often signal broader market stress.
Is a drawdown the same as a loss?
No. A drawdown measures the decline from a peak price and represents an unrealized paper decline. You only incur an actual loss if you sell while the drawdown is in effect. Many investors use drawdowns as buying opportunities rather than selling signals, purchasing quality assets at discounted prices during temporary declines.
What is the difference between a drawdown and a correction?
A drawdown measures any decline from an asset's all-time high, regardless of size, and applies to individual stocks, ETFs, or crypto. A correction is a specific term for a market-wide decline of 10–20% from a recent peak. All corrections involve drawdowns, but not all drawdowns are corrections. See our glossary for more investing terms.
How do you calculate the drawdown of a stock?
Use the formula: Drawdown % = ((Current Price − All-Time High) / All-Time High) × 100. For example, if a stock reached an all-time high of $200 and is currently trading at $150, the drawdown is (($150 − $200) / $200) × 100 = −25%. The stock is 25% below its peak price.
