Drawdown
Maximum loss from a previous peak.
A drawdown is the percentage decline from the most recent peak to the lowest point before a new high is reached. It measures the pain of a position: not how far it has fallen in absolute terms, but how far it has fallen from the moment it was at its highest. A 50% drawdown means the price has been cut in half from its peak.
There is a stark mathematical asymmetry in drawdowns: recovering from a 50% loss requires a 100% gain. Recovering from a 75% loss requires a 300% gain. This asymmetry is one of the fundamental reasons why risk management — reducing large drawdowns — matters more than maximizing absolute returns in favorable periods.
Worked example
Meta Platforms (META) in 2022 suffered a 76% drawdown from its September 2021 peak ($380) to its November 2022 low ($90). It took roughly 18 months to return to pre-drawdown levels — only through a massive cost-reduction program and a rebound in advertising revenue. Not all stocks recover: many companies in prolonged drawdowns never return to previous highs.
The S&P 500 historically averages a drawdown of roughly 14% in ordinary corrections, and drawdowns above 30% in recessions (2008: -57%, 2020: -34%). A 100%-equity U.S. portfolio had to wait five years to recover from the 2008 drawdown. Reducing the average portfolio beta does not eliminate drawdowns but dampens them.
When it's used
Drawdown is the most direct measure of the real risk of a portfolio or stock over time. First, comparing strategies: two portfolios with the same annualized return are not equivalent if one had a maximum drawdown of 15% and the other 55%. Second, planning the emotional capacity to hold through losses: an investor who cannot maintain a position through a 30% drawdown should size positions differently. Third, identifying slow recoveries — stocks with historically deep drawdowns take longer on average to return to highs.
Limits
Drawdown looks backward: it does not predict how deep the next one will be. Historical maximum drawdown is almost always exceeded by the next crisis: unexpected market events produce losses that surpass those of previous crises. Drawdown also does not distinguish between temporary and permanent loss: a stock in a 70% drawdown might represent the maximum opportunity (unjustified collapse) or the beginning of a bankruptcy.
Frequently asked
Are drawdown and loss the same thing?
No. A loss is realized P&L — it is locked in when you sell. Drawdown is the unrealized decline from a peak, measured at any point in time. You can have a 40% drawdown and not have lost anything if you have not sold — but the psychological volatility of the journey is real.
How long does it take to recover from a drawdown?
It depends on the depth and the quality of the asset. A 20% drawdown on a diversified index: historically 12–24 months on average. A 50% drawdown: 2 to 7 years on average. For individual stocks in structural decline: never, in many cases.
What is an 'underwater period'?
The period of time spent below the previous peak — in other words, the time spent in drawdown. A long underwater period is psychologically wearing even if the final value recovers: this is why the drawdown profile matters in evaluating a strategy, not just the total return.
