What is max drawdown?

Max drawdown is the largest peak-to-trough decline over a period — the pain metric that total return alone hides.

Why drawdown is the pain metric that returns alone hide

A strategy or ticker can post a healthy total return over a year and still have put a holder through a brutal -40% stretch along the way — the ending number says nothing about what it felt like to hold through the middle. Drawdown captures exactly that worst-case experience, independent of where the price eventually recovered to.

Frequently asked questions

Why does a 50% drawdown need a 100% gain to recover?

Recovery math is asymmetric: losing half your position's value means the remaining half must double just to get back to the starting point.

Is a good total return enough on its own?

No — a strategy can post a healthy total return while still having put a holder through a severe drawdown along the way; the ending number alone hides that experience.
