Returns get all the attention. Drawdowns are what decide whether you can actually stick with an investment or trading strategy long enough for returns to matter.

Drawdown is a simple concept - how far something fell from a prior peak - but it’s also one of the most practical risk metrics you can track because it describes the “pain” investors and traders experience during real market stress.

This guide breaks down drawdown (and maximum drawdown) properly, shows you the math, explains how to read an underwater chart, and shows how to visualize drawdowns using Investorean’s Asset Drawdown Chart tool.

What is a drawdown?

A drawdown is the decline in value from a previous peak to a subsequent trough, typically expressed as a percentage. It’s used to measure historical downside risk, compare investments or strategies, and monitor portfolio risk over time.

Two details matter:

Drawdown is measured from the peak, not from your entry price.

Drawdown is a path measure. Two assets can end the year at the same return, but the one that suffered a deeper drawdown was harder (and riskier) to hold in real life.

Peak, trough, high-water mark: the language of drawdowns

If you want drawdown to stop being vague, you need clean terms:

Peak / high-water mark: the highest value reached so far.

Trough / low-water mark: the lowest point after that peak (before a new high is reached).

Drawdown: how far the current value is below the running peak (usually shown as a negative %).

In more formal terms used in quantitative finance, drawdown is the difference between current value and the running maximum (“historic high point”).

How to calculate drawdown

The practical drawdown formula

Investorean defines drawdown as the % decline from a running peak:

Drawdown (%) = (Current Price / Running Peak − 1) × 100

Example:

Running peak = 110

Current price = 80

Drawdown = (80 / 110 − 1) × 100 = −27.3%

The “peak-to-trough” drawdown idea (same concept, different framing)

Most definitions describe drawdown as the peak-to-trough decline over a selected period. That’s the same idea, just described in plain English.

Current drawdown vs maximum drawdown (MDD)

These get mixed up constantly.

Current drawdown

Current drawdown is where you are right now relative to the most recent running peak.

If current drawdown is −12%, the asset is 12% below its latest high.

Maximum drawdown (MDD)

Maximum drawdown (MDD) is the worst peak-to-trough decline observed in the selected time window, before a new peak is reached.

Why investors obsess over MDD: it captures the “most unfavorable” experience - effectively the loss you’d have suffered if you bought at the peak and sold at the bottom.

Drawdown duration and time to recovery

Depth is only half the story. How long you stay underwater matters just as much.

Drawdown duration: how long the asset stays below its prior peak.

Time to recovery (time back to high-water mark): how long it takes to regain the previous peak after the decline.

This is why two assets can share the same max drawdown but feel completely different:

Asset A: −25% drawdown, recovers in 3 months

Asset B: −25% drawdown, recovers in 3 years

Same depth. Totally different risk in real life.

Drawdown vs loss vs volatility

These are related, but not interchangeable.

Drawdown vs loss

A drawdown is measured from the asset’s peak. A loss is typically measured from your purchase price (or your realized exit). You can be in a large drawdown from the peak and still be profitable if you entered earlier at a lower price.

Drawdown vs volatility

Volatility describes how much returns fluctuate (up and down). Drawdown focuses specifically on declines from previous highs. Two assets can have similar volatility and very different drawdowns - and very different recovery behavior.

Drawdown in a trading account

In trading, drawdown is commonly described as the decline in an account from its peak equity value to its lowest point before recovering.

Why drawdown matters

Drawdown matters because:

It represents actual pain, not abstract “risk.”

It destroys compounding by shrinking the capital base.

Recovery is nonlinear - the deeper the drawdown, the more brutal the required return to get back to even.

The recovery math

If you lose X%, you need more than X% to recover - because you’re earning returns on a smaller base.

Drawdown	Required gain to recover
−10%	+11.1%
−20%	+25.0%
−30%	+42.9%
−40%	+66.7%
−50%	+100%
−60%	+150%
−70%	+233.3%

That “−50% requires +100%” asymmetry is not a motivational quote - it’s arithmetic, and it’s exactly why deep drawdowns can set portfolios back for years.

What does “−20% drawdown” signal?

A −20% drawdown simply means the asset fell 20% from its most recent peak. Many market commentators and index discussions use ~20% peak-to-trough declines as a common bear-market threshold for broad indexes.

How investors use drawdown

Long-term investors track drawdowns to answer questions like:

“How bad did this portfolio get during a real crisis?”

“Did it fall deeper than the benchmark?”

“How long did it take to recover?”

Practical uses:

Comparing funds/ETFs with similar returns: drawdown exposes which one required stronger stomach (and more time) to hold.

Stress testing your allocation: drawdown history highlights whether your asset mix really diversifies when it matters.

Setting realistic expectations: if you can’t tolerate the historical drawdowns of an asset class, you’ll likely make the classic mistake: selling during the drawdown and missing the recovery.

How traders use drawdown

Traders focus on drawdown for survival and risk control:

Strategy evaluation: a strategy isn’t “good” if it requires a massive drawdown before it works.

Risk limits: many traders set maximum allowable drawdown thresholds (daily/weekly/monthly) to prevent a bad streak from turning into account death.

Position sizing: deeper drawdown usually means you’re overexposed relative to the strategy’s edge (or you’re trading something you don’t understand).

Prop firm constraints: “max daily drawdown” / “max trailing drawdown” rules essentially force traders to manage equity curve drawdowns, not just per-trade losses.

In short: drawdown is how risk shows up in the real world - especially when you’re leveraged.

What is a drawdown chart (underwater chart)?

A drawdown chart (often called an underwater chart) plots the percent decline from each historical peak over time.

How to read it:

0% line = new highs (at peak)

Negative values = underwater (below the latest peak)

Deeper valleys = deeper drawdowns

Wider valleys = longer time in drawdown / recovery

Investorean’s Asset Drawdown Chart tool

If you want to see drawdowns instead of guessing, use Investorean’s Asset Drawdown Chart. It lets you visualize:

Drawdown as the % drop from the running peak to the current value over time

The difference between current drawdown and maximum drawdown

Drawdown charts (underwater charts), where 0% is the high-water mark and negative values show how far below the peak the asset is

Benchmark comparison vs the S&P 500, which helps you see whether an asset falls deeper or recovers slower than the market

How to use it

Open the tool: https://investorean.com/tools/asset-drawdown/

Type a ticker or asset name into the search field.

(Optional) Use the S&P 500 benchmark toggle to compare drawdowns.

Read the chart:

Look for the deepest dip (max drawdown in the selected period).

Look for how long it stayed below 0% (duration / time to recovery).

Compare to S&P 500: deeper or slower recoveries usually mean higher downside risk relative to the benchmark.

One nuance to mention (dividends & data)

Drawdown results depend on the underlying data series:

Price-return vs total-return (with dividends reinvested) can materially change drawdown depth and recovery timing.

Most datasets are split-adjusted, but dividend handling can vary.

If you’re analyzing long-term drawdowns for dividend-heavy assets, total-return data is the cleaner picture when available. Investorean currently only provides the price-return data.

Common mistakes when people talk about drawdown

1) Treating max drawdown like a “forecast”

It’s backward-looking. It shows what happened, not what must happen next.

2) Ignoring the time dimension

Depth without duration is incomplete. A smaller drawdown that lasts years can be worse than a bigger drawdown that recovers quickly (depending on your goals).

3) Comparing drawdowns across different time windows

Max drawdown changes with the timeframe. A 3-year window and a 20-year window are not comparable unless you explicitly standardize the lookback.

4) Confusing drawdown with “my loss”

Drawdown is from the peak; your P&L is from your entry. Those are not the same thing.

5) Using drawdown alone

Even Investopedia explicitly notes MDD doesn’t tell you how often losses occur or how long recovery takes. It’s one metric, not a complete risk model.

Drawdown-based ratios investors actually use

Drawdown isn’t only a standalone metric. It’s also embedded in popular risk-adjusted performance ratios.

Calmar Ratio

Compares average annual return to maximum drawdown over a (commonly) 3-year period. It’s a “returns vs worst pain” lens.

MAR Ratio

MAR = CAGR since inception ÷ maximum drawdown. Often used for hedge funds, CTAs, and trading strategies when you want a long-run risk-adjusted comparison.

RoMaD (Return Over Maximum Drawdown)

RoMaD frames a simple question: “Am I willing to accept an occasional drawdown of X% to generate an average return of Y%?”

FAQ

What is a “good” drawdown?

There is no universal “good” drawdown. It depends on:

your time horizon,

your leverage (if any),

your strategy’s expected returns,

and whether you can emotionally and financially survive the recovery path.

The clean way to think about it: a drawdown is acceptable only if you can stick with the strategy through it.

What does a −20% drawdown mean in plain English?

It means the asset or portfolio fell 20% from its most recent peak. Some market discussions use −20% as a common bear-market threshold for broad indexes.

Is drawdown the same as volatility?

No. Volatility captures the overall fluctuation of returns (up and down). Drawdown focuses specifically on declines from highs and how deep/long they get.

Does max drawdown tell me how long recovery will take?

No. MDD is depth-only. It doesn’t include recovery time or frequency of declines.

Why use a drawdown chart instead of just looking at price?

Because an underwater chart shows the sequence of pain: depth + duration. Price charts can look “fine” while hiding multi-year periods underwater.
