Drawdown
The peak-to-trough decline in a portfolio or trading account's value, expressing how much capital was lost before a recovery to a new high.
Definition
A drawdown is the percentage (or absolute) decline from a portfolio's or trading strategy's peak equity value to its lowest subsequent value before a new peak is reached. It captures the lived experience of loss that a trader or investor endures during a losing streak or adverse market phase. Drawdown is distinct from a simple daily P&L loss: it is a running measure that begins the moment the portfolio makes a new high and ends only when that previous high is surpassed again. The full sequence — peak, trough, and recovery — defines a single drawdown episode. Traders frequently track drawdown alongside risk-reward ratio to evaluate whether a strategy's returns justify the periods of loss it inflicts.
Why it matters
Drawdown matters because of the deeply asymmetric mathematics of loss and recovery. A 10% drawdown requires an 11.1% gain to recover; a 25% drawdown needs a 33.3% gain; a 50% drawdown demands a full 100% gain. This asymmetry is a major reason why many F&O traders who appear profitable on individual trades eventually blow up their accounts — a single large losing month can erase months of small wins and then require an unrealistic recovery. Indian F&O markets, with their weekly expiry structure and high leverage, can produce sharp, fast drawdowns: a short-straddle trader on Bank Nifty can suffer a 20–30% drawdown in a single session during a surprise RBI announcement or budget day. Drawdown duration — the number of days or weeks before a new high is reached — is equally important; a long, grinding drawdown is psychologically harder to sustain than a sharp, brief one. Prop firms and algo funds in India typically impose hard maximum drawdown limits at which trading is automatically suspended.
Formula
Drawdown at time t = (Peak value up to t − Value at t) ÷ Peak value up to t, expressed as a percentage.
If your account peaked at ₹10,00,000 and currently stands at ₹8,20,000, the current drawdown = (₹10,00,000 − ₹8,20,000) ÷ ₹10,00,000 = 18%. The drawdown remains open (ongoing) until the account recovers to ₹10,00,000 or beyond.
Example
Suppose you run a hypothetical options-selling strategy on Nifty weekly expiries. Your account grows from ₹5,00,000 to ₹7,50,000 over six months — a 50% gain — and then suffers four consecutive losing weeks during a volatile election period, falling to ₹6,30,000. Your current drawdown is (₹7,50,000 − ₹6,30,000) ÷ ₹7,50,000 = 16%. To close this drawdown and reach a new high, you need a 19% gain from ₹6,30,000. If your risk management plan specifies a 20% drawdown limit before halving position size, you are approaching that threshold and should review sizing now rather than after breaching it. This is a hypothetical illustration; real strategy performance depends on market conditions, strikes selected, and hedging discipline.
